Notational Conventions
In this document, the following notational conventions are used:
Program listings, program examples, and interactive displays are shown
in a special typeface. Examples use a bold versionof the spe-
cial typeface for emphasis. Interactive displays use boldto distinguish
commands that you enter from items that the system displays (such as
prompts, command output, error messages, etc.). Some interactive
displays use italicsto describe the type of information that should be
entered.
Here is a sample program listing:

Setting Up the Code Generation Environment
1.3 Setting Up the Code Generation Environment
Before or after you install the code generation tools, you can define environ-
ment variables that set certain software tool parameters you normally use. An
environment variable is a special system symbol that you define and associate
to a string. A program uses this symbol to find or obtain certain types of
information.
When you use environment variables, default values are set, making each
individual invocation of the tools simpler because these parameters are auto-
matically specified. When you invoke a tool, you can use command-line
options to override many of the defaults that are set with environment vari-
ables.
The code generation tools use the following environment variables:
A_DIR
C_DIR
C_OPTION
TMP
By default, the installation program modifies your autoexec.bat file and sets
up these environment variables:
set PATH=c:\tool_dir;%PATH%
set A_DIR=c:\tool_dir
set C_DIR=c:\tool_dir
If you choose not to have the environment variables set up automatically, you
can modify your autoexec.bat file to include the set commands above.
In addition to setting up environment variables, you must modify your path
statement. The following subsections describe how to modify your path state-
ment and how to define the environment variables that the code generation
tools use.

Setting Up the Code Generation Environment
Identifying the directory that contains the executable files (PATH statement)
You must include the tool_dir directory in your PATH statement so that you can
specify the assembler and compiler tools without specifying the name of the
directory that contains the executable files.
If you modify your autoexec.bat file to change the path information, add
the following to the end of the PATH statement:
;c:\tool_dir
If you set the PATH statement from the command line, enter the following:
set PATH=c:\tool_dir;%PATH%
The addition of ;%PATH% ensures that this PATH statement does not
undo the PATH statements in any other batch files (including the
autoexec.bat file).
Identifying alternate directories for the assembler to search (A_DIR)
The assembler uses the A_DIR environment variable to name alternative
directories for the assembler to search. To set the A_DIR environment vari-
able, use this syntax:
set A_DIR=pathname [;pathname . . .]
1
2
The pathnames are directories that contain copy/include files or macro
libraries. You can separate the pathnames with a semicolon or with a blank.
Once you set A_DIR, you can use the .copy, .include, or.mlib directive in
assembly source without specifying path information.
If the assembler does not find the file in the directory that contains the current
source file or in directories named by the –ioption (which names alternate
directories), it searches the paths named by the A_DIR enviroment variable.
For more information on the –i option, see the TMS470R1x Assembly
Language Tools User’s Guide or the TMS470R1x Optimizing C Compiler
User’s Guide.
Identifying alternate directories for the compiler to search (C_DIR)
The compiler uses the C_DIR environment variable to name alternative direc-
tories for the compiler to search. To set the C_DIR environment variable, use
this syntax:
set C_DIR=pathname [;pathname . . .]
1
2
The pathnames are directories that contain #include files or function libraries
(such as stdio.h). You can separate the pathnames with a semicolon or with
a blank. In C source, you can use the #include directive without specifying path
information. Instead, you can specify the path information with C_DIR.

Setting default shell options (C_OPTION)
You might find it useful to set the compiler, assembler, and linker shell default
options using the C_OPTION environment variable. If you do this, the shell
usesthedefaultoptionsand/orinputfilenamesthatyounamewithC_OPTION
every time you run the shell.
Setting the default options with the C_OPTION environment variable is useful
when you want to run the shell consecutive times with the same set of options
and/or input files. After the shell reads the command line and the input file-
names, it reads the C_OPTION environment variable and processes it.
To set the C_OPTION environment variable, use this syntax:
set C_OPTION=option [;option . . .]
1
2
Environment variable options are specified in the same way and have the
same meaning as they do on the command line. For example, if you want to
always run quietly (the –q option), enable C source interlisting (the –s option),
andlink(the–zoption), setuptheC_OPTIONenvironmentvariableasfollows:
set C_OPTION=–qs –z
In the following examples, each time you run the compiler shell, it runs the
linker. Any options following –z on the command line or in C_OPTION are
passed to the linker. This enables you to use the C_OPTION environment vari-
able to specify default compiler and linker options and then specify additional
compiler and linker options on the shell command line. If you have set –z in
the environment variable and want to compile only, use the –c option of the
shell. These additional examples assume C_OPTION is set as shown above:
cl470 *c
cl470 –c *.c
; compiles and links
; only compiles
cl470 *.c –z lnk.cmd
; compiles and links using a
; command file
cl470 –c *.c –z lnk.cmd ; only compiles (–c overrides –z)
For more information about shell options, see the TMS470R1x Optimizing C
Compiler User’s Guide. For more information about linker options, see the
TMS470R1x Assembly Language Tools User’s Guide .

Setting Up the Code Generation Environment
Specifying a temporary file directory (TMP)
The compiler shell program creates intermediate files as it processes your
program. By default, the shell puts intermediate files in the current directory.
However, you can name a specific directory for temporary files by using the
TMP environment variable.
Using the TMP environment variable allows use of a RAM disk or other file
systems. It also allows source files to be compiled from a remote directory
without writing any files into the directory where the source resides. This is
useful for protected directories.
To set the TMP environment variable, use this syntax:
set TMP=pathname
For example, to set up a directory named temp for intermediate files on your
hard drive, enter:
set TMP=c:\temp
Resetting defined environment variables
The environment variables that you define remain set until you reboot the
system. If you want to clear an environment variable, use this command:
set variable name=
For example, to reset the A_DIR environment variable, enter:
set A_DIR
Verifying that the environment variables are set
To verify that the environment variables are set, open a DOS box and enter:
set
This command lists the path and environment variables and their current
values.

Performance Considerations / Where to Go From Here
1.4 Performance Considerations
You may notice a speed degradation when you use the code generation tools
with DOS or Windows 3.1x. This speed degradation may occur when you use
DOS with the tools to get appropriate host memory support.
If you encounter error messages when you use the tools on a PC with DOS,
run PMINFO to determine your system configuration before you contact tech-
nical support. For more information about PMINFO, see Appendix A, Trouble-
shooting DOS systems.
1.5 Where to Go From Here
Your code generation tools are now installed on your DOS or Windows 3.1x
system. Now you should do each of the following tasks:
Go to Chapter 5, Getting Started With the Code Generation Tools. This
chapter provides you with an overview of how to invoke and use the
assembler, linker, and compiler.
Read Chapter 6, Release Notes. This chapter explains the new features
included in release 1.20 of the code generation tools.
Use Appendix A, Troubleshooting DOS Systems, as necessary. This
appendix lists kernel and DOS/4G error messages and explains how
you can resolve the messages.

2
export A_DIR
(Be sure to enclose the directory names within quotes.)
The pathnames are directories that contain copy/include files or macro librar-
ies. You can separate the pathnames with a semicolon or a blank. Once you
set A_DIR, you can use the .copy, .include, or .mlib directive in assembly
source without specifying path information.
If the assembler does not find the file in the directory that contains the current
source file or in directories named by the –i option (which names alternate di-
rectories), it searches the paths named by the A_DIR environment variable.

For more information on the –i option, see the TMS470R1x Assembly Lan-
guage Tools User’s Guide or the TMS470R1x Optimizing C Compiler User’s
Guide.
Identifying alternate directories for the compiler to search (C_DIR)
The compiler uses the C_DIR environment variable to name alternate direc-
tories that contain #include files and function libraries. To set the C_DIR envi-
ronment variable, use this syntax:
For C shells:
setenv C_DIR “pathname [;pathname . . .]”
1
2
For Bourne or Korn shells:
C_DIR=“pathname [;pathname . . .]”
1
2
export C_DIR
(Be sure to enclose the directory names within quotes.)
The pathnames are directories that contain #include files or libraries (such as
stdio.h). You can separate pathnames with a semicolon or with blanks. In C
source, you can use the #include directive without specifying path information.
Instead, you can specify the path information with C_DIR.
Setting default shell options (C_OPTION)
You may find it useful to set the compiler, assembler, and linker default shell
options using the C_OPTION environment variable. If you do this, the shell
usesthedefaultoptionsand/orinputfilenamesthatyounamewithC_OPTION
every time you run the shell.
Setting up default options with the C_OPTION environment variable is useful
when you want to run the shell consecutive times with the same set of options
and/or input files. After the shell reads the command line and the input file-
names, it reads the C_OPTION environment variable and processes it.
To set the C_OPTION environment variable, use this syntax:
For C shells:
setenv C_OPTION ”option [option . . .]”
1
2
For Bourne or Korn shells:
C_OPTION=”option [option . . .]”
1
2
export C_OPTION

Setting Up the Code Generation Environment
(Be sure to enclose the options within quotes.)
Environment variable options are specified in the same way and have the
same meaning as they do on the command line. For example, if you want to
always run quietly (the –q option), enable C source interlisting (the –s option),
andlink(the–zoption), setuptheC_OPTIONenvironmentvariableasfollows:
For C shells:
setenv C_OPTION ”–qs –z”
For Bourne or Korn shells:
C_OPTION=”–qs –z”
export C_OPTION
In the following examples, each time you run the compiler shell, it runs the
linker. Any options following –z on the command line or in C_OPTION are
passed to the linker. This enables you to use the C_OPTION environment vari-
able to specify default compiler and linker options and then specify additional
compiler and linker options on the shell command line. If you have set –z in
the environment variable and want to compile only, use the –c option of the
shell. These additional examples assume C_OPTION is set as shown above:
cl470 *.c
cl470 –c *.c
; compiles and links
; only compiles
cl470 *.c –z lnk.cmd
; compiles and links using a
; command file
cl470 –c *.c –z lnk.cmd ; only compiles (–c overrides –z)
For more information about shell options, see the TMS470R1x Optimizing C
Compiler User’s Guide. For more information about linker options, see the
TMS470R1x Assembly Language Tools User’s Guide.
Specifying a temporary file directory (TMP)
Thecompilershellprogramcreatesintermediatefilesasitprocessesyourpro-
gram. By default, the shell puts intermediate files in the current directory. How-
ever, you can name a specific directory for temporary files by using the TMP
environment variable.
Using the TMP environment variable allows use of a RAM disk or other file
systems. Italsoallowsyoutocompilesourcefilesfromaremotedirectorywith-
out writing any files into the directory where the source resides. This is useful
for protected directories.

Setting Up the Code Generation Environment
To set the TMP environment variable, use this syntax:
For C shells:
setenv TMP ”pathname”
For Bourne or Korn shells:
TMP=”pathname”
export TMP
(Be sure to enclose the directory name within quotes.)
For example, to set up a directory named temp for intermediate files, enter:
For C shells:
setenv TMP ”/temp”
For Bourne or Korn shells:
TMP=”/temp”
export TMP
Reinitializing your shell
When you modify your shell configuration file, you must ensure that the
changes are made to your current session. Use one of the following com-
mands to reread your system initialization file:
For C shells:
source ~/.cshrc
For Bourne or Korn shells:
source ~/.profile
Resetting defined environment variables
The environment variables that you define remain set until you reboot the sys-
tem. If you want to clear an environment variable, use this command:
For C shells:
unsetenv variable_name
For Bourne or Korn shells:
unset variable_name
For example, to reset the A_DIR environment variable, enter one of these
commands:
For C shells:
unsetenv A_DIR
For Bourne or Korn shells:
unset A_DIR

Installing the Code Generation Tools
4.2 Installing the Code Generation Tools
This section helps you install the code generation tools on your hard-disk sys-
tem. The software package is shipped on a CD-ROM. To install the tools on
an HP workstation, you must mount the CD-ROM, copy the files to your sys-
tem, and unmount the CD-ROM.
Note:
If you are running HP-UX 9.0x, you must have root privileges to mount or
unmount the CD-ROM. If you do not have root privileges, get help from your
system administrator.
Mounting the CD-ROM
As root, you can mount the CD-ROM using the UNIX mount command or the
SAM (system administration manager):
To use the UNIX mount command, enter the following from a command
shell:
mount –rt cdfs /dev/dsk/your_cdrom_device /cdrom
exit
Make the hp directory on the CD-ROM the current directory. For example,
if the CD-ROM is mounted at /cdrom, enter the following:
cd /cdrom/hp
To use SAM to mount the CD-ROM, see System Administration Tasks, the
HP documentation about SAM, for instructions.
Copying the files
After you mount the CD-ROM, log out as root and log back on as yourself. You
must create the directory that will contain the tools software and copy the soft-
ware to that directory.
1) Create a tools directory on your hard disk. To create this directory, enter:
mkdir /your_pathname/tool_dir
2) Copy the files from the CD-ROM to your hard-disk system:
cp –r * /your_pathname/tooldir

Setting up the software tools using a C shell
If you are using a C shell, enter the following:
setenv C_DIR ”tool_dir”
setenv A_DIR ”tool_dir”
set path=(tool_dir $path)
You can move the setenv and set path commands into your .login or .cshrc
file to avoid entering these commands each time you invoke a new shell.
Setting up the software tools using a Korn shell
If you are using a Bourne or Korn shell, enter the following:
C_DIR=tool_dir
A_DIR=tool_dir
PATH=tool_dir:$PATH
You can move the environment variable instructions into your .kshrc file to
avoid entering these commands each time you invoke a new shell.
Unmounting the CD-ROM
You must unmount the CD-ROM after copying the files. As root, enter the fol-
lowing from a command shell:
cd
umount /cdrom
exit

Setting Up the Code Generation Environment
4.3 Setting Up the Code Generation Environment
Before or after you install the code generation tools, you can define environ-
ment variables that set certain software tool parameters you normally use. An
environment variable is a special system symbol that you define and assign
to a string. A program uses this symbol to find or obtain certain types of
information.
When you use environment variables, default values are set, making each
individual invocation of the tools simpler because these parameters are auto-
matically specified. When you invoke a tool, you can use command-line op-
tions to override many of the defaults that are set with environment variables.
The code generation tools use the following environment variables:
A_DIR
C_DIR
C_OPTION
TMP
You can set up the environment variables o the command line or in your .login
or .cshrc file (for C shells) or .profile file (for Bourne or Korn shells). To set up
these environment variables in your system initialization file, enter the same
commands that you would enter on the command line in the file.
In addition to setting up environment variables, you must modify your path
statement. The following subsections describe how to modify your path state-
ment and how to define the environment variables that the code generation
tools use.

Setting Up the Code Generation Environment
Identifying the directory that contains the executable files (path statement)
You must include the tool_dir directory in your path statement so that you can
specify the assembler and compiler tools without specifying the name of the
directory that contains the executable files.
If you modify your .cshrc file (for C shells) or .profile file (for Bourne or Korn
shells) to change the path information, add the following to the end of the
path statement:
/your_pathname/tool_dir
If you set the path statement from the command line, use this format:
For C shells:
set path=(/your_pathname/tool_dir $path)
For Bourne or Korn shells:
PATH=/your_pathname/tool_dir $PATH
The addition of $path or $PATH ensures that this path statement does not
undo the path statements in the .cshrc or .profile file.
Identifying alternate directories for the assembler (A_DIR)
The assembler uses the A_DIR environment variable to name alternative
directories for the assembler to search. To set the A_DIR environment vari-
able, use this syntax:
For C shells:
setenv A_DIR ”pathname [;pathname … ]”
1
2
For Bourne or Korn shells:
A_DIR=”pathname [;pathname … ]”
1
2
export A_DIR
(Be sure to enclose the directory names within quotes.)
The pathnames are directories that contain copy/include files or macro librar-
ies. You can separate the pathnames with a semicolon or a blank. Once you
set A_DIR, you can use the .copy, .include, or .mlib directive in assembly
source without specifying path information.
If the assembler does not find the file in the directory that contains the current
source file or in directories named by the –i option (which names alternate
directories), it searches the paths named by the A_DIR environment variable.
For more information on the –i option, see the TMS470R1x Assembly
Language Tools User’s Guide or the TMS470R1x Optimizing C Compiler
User’s Guide.

Identifying alternate directories for the compiler (C_DIR)
The compiler uses the C_DIR environment variable to name alternate direc-
tories that contain #include files and libraries. To set the C_DIR environment
variable, use this syntax:

The pathnames are directories that contain #include files or libraries (such as
stdio.h). You can separate pathnames with a semicolon or with blanks. In C
source, you can use the #include directive without specifying path information.
Instead, you can specify the path information with C_DIR.

You may find it useful to set the compiler, assembler, and linker shell default
options using the C_OPTION environment variable. If you do this, the shell

5.1 Getting Started With the Assembler and Linker
This section provides a quick walkthrough of the assembler and linker so that
you can get started without reading the entire TMS470R1x Assembly
Language Tools User’s Guide. Example 5–1 through Example 5–6 show the
most common methods for invoking the assembler and linker.
1) Create two short source files to use for the walkthrough; call them
file1.asm and file2.asm. (See Example 5–1 and Example 5–2.)
Example 5–1. file1.asm
.global inclw
start: MOV
MOV
r6, #0
r7, #0
loop: BL
inclw
loop
BCC
.end
Example 5–2. file2.asm
.global inclw
inclw: ADDS
r7, r7, #1
ADDCSS r6, r6, #1
MOV
pc, lr
.end
2) Enter the following command to assemble file1.asm:
asm470 file1
The asm470 command invokes the assembler. The input source file is
file1.asm. (If the input file extension is .asm, you do not have to specify the
extension; the assembler uses .asm as the default.)
This example creates an object file called file1.obj. The assembler creates
an object file only if there are no errors in assembly. You can specify a
name for the object file, but if you do not, the assembler uses the input file-
name with an extension of .obj.

Getting Started With the Assembler and Linker
3) Now enter the following command to assemble file2.asm:
asm470 file2.asm –l
This time, the assembler creates an object file called file2.obj. The –l
(lowercase L) option tells the assembler to create a listing file; the listing
file for this example is called file2.lst. It is not necessary to create a listing
file, but it gives you information and assures you that the assembly has
resulted in the desired object code. The listing file for this example is
shown in Example 5–3.

4) Now enter the following command to link file1.obj and file2.obj:
lnk470 file1 file2 –m lnker2.map –o prog.out
The lnk470 command invokes the linker. The input object files are file1.obj
and file2.obj. (If the input file extension is .obj, you do not have to specify
the extension; the linker uses .obj as the default.) The linker combines
file1.obj and file2.obj to create an executable object module called
prog.out. The –o option supplies the name of the output module.
Example 5–4 shows the map file resulting from this operation. (The map
file is produced only if you use the –m option.)

Getting Started With the Assembler and Linker
The two files, file1 and file2, can be linked together with or without a com-
mand file. However, using a command file allows you to configure your
memory using the MEMORY and SECTIONS directives:
The MEMORY directive lets you specify a model of target memory so
that you can define the types of memory your system contains and the
address ranges they occupy.
The SECTIONS directive describes how input sections are combined
into output sections and specifies where output sections are placed in
memory.
You can include the linker options and filenames in the linker command
file, or you can enter them on the command line. If you do not include a
linker command file, the linker uses a default allocation algorithm. Refer to
the TMS470R1x Assembly Language Tools User’s Guide for more in-
formation about the linker command file and the default allocation algo-
rithm.
Example 5–5. Sample Linker Command File, linker2.cmd
/* Specify the System Memory Map */
MEMORY
{
D_MEM : org = 0x00000000 len = 0x00001000 /* Data Memory
(RAM) */
P_MEM : org = 0x00001000 len = 0x00001000 /* Program Memory (ROM) */
}
/* Specify the Sections Allocation Into Memory */
SECTIONS
{
.data
.text
: {} > D_MEM /* Initialized Data */
: {} > P_MEM /* Code */
}
Typing in the following command line using the linker command file shown
in Example 5–5 results in the map file shown in Example 5–6.

Getting Started With the C Compiler
5.2 Getting Started With the C Compiler
The TMS470R1x C compiler consists of many phases, including parsing, opti-
mization, and code generation. The simplest way to compile is to use the shell
program, which is included with the compiler. This section provides a quick
walkthroughsothatyoucangetstartedwithoutreadingtheentireTMS470R1x
Optimizing C Compiler User’s Guide.
1) Create a sample file called function.c that contains the following code:
/**************************************/
/*
function.c
*/
*/
/* (Sample file for walkthrough)
/**************************************/
int main(int i)
{
return(i < 0 ? –i : i );
}
2) To invoke the shell program to compile and assemble function.c, enter:
cl470 –o function
By default, the TMS470R1x shell program compiles and assembles 32-bit
instructions. To compile 16-bit instructions, use the –mt option:
cl470 –o –mt funtion
The shell program prints the following information as it compiles the pro-
gram:

By default, the shell deletes the assembly language file from the current
directory after the file is assembled. If you want to inspect the assembly
language output, use the –k option to retain the assembly language file:
cl470 –o –k function

Getting Started With the C Compiler
3) Also by default, the shell creates a COFF object file as output; however,
if you use the –z option, the output is an executable object module. The
following examples show two ways of creating an executable object
module:
a) The example in step 2 creates an object file called function.obj. To
create an executable object module, run the linker separately by
invoking lnk470 as in the following example:
lnk470 –c function.obj lnk32.cmd –o function.out –l rts32.lib
The –c linker option tells the linker to observe the C language linking
conventions. The linker command file, lnk32.cmd, is shipped with the
code generation tools. The –o option names the output module,
function.out; if you don’t use the –o option, the linker names theoutput
module a.out. The –l option names the runtime-support library. You
must have a runtime-support library before you can create an execut-
able object module; the prebuilt runtime-support libraries rts32.lib and
rts16.lib are included with the code generation tools.
b) In this example, use the –z shell option, which tells the shell program
to run the linker. The –z option is followed by linker options.
cl470 –o function.c –z lnk32.cmd –o function.out –l rts32.lib
For more information on linker commands, see the Linker Description
chapter of the TMS470R1x Assembly Language Tools User’s Guide.
4) The TMS470R1x compiler package also includes an interlist utility. This
program interlists the C source statements as comments in the assembly
language compiler output, allowing you to inspect the assembly language
generated for each line of C. To run the interlist utility, invoke the shell pro-
gram with the –s option. For example:
cl470 –s function –z lnk32.cmd –o function.out
The output of the interlist utility is written to the assembly language file
created by the compiler. (The shell –s option implies –k; that is, when you
use the interlist utility, the assembly file is automatically retained.)

Release Enhancements
6.2 Release Enhancements
Release 1.20 of the TMS470R1x code generation tools contains general
enhancements as well as enhancements specific to the assembler and
compiler. The following sections list these enhancements.
General enhancements
The TMS470R1x general enhancements include the following items:
All known bugs have been removed.
COFF version 2 is supported. Section names are no longer limited to eight
characters, and filenames are no longer limited to 14 characters. Section
name length is unrestricted, and filename length is restricted by the con-
ventions of your operating system.
Note: Using Version 1 COFF
If you depend on a third-party COFF-dependent tool that does not support
version 2 COFF, then use the –v1 linker option. The –v1 option instructs the
linker to generate version 1 COFF. Ensure that your object modules do not
have section names that are longer than eight characters or filenames that
are longer than 14 characters. The –v1 option is a temporary option for this
release and it will be removed in a future release.
Assembler enhancements
The TMS470R1x assembler enhancements are as follows:
A feature of COFF version 2 is the use of subsections. You can create
subsections of any section to give you tighter control of the memory map.
Subsectionsarecreatedusingthe.sectand.usectdirectives. Forinforma-
tion on creating subsections, see the Introduction to Common Object File
Format chapter of the TMS470R1x Assembly Language Tools User’s
Guide; for memory map examples using subsections, see the Linker
Description chapter.
The assembler supports conditionally linked sections. You select sections
for conditional linking with the .clink assembler directive.
The .clink directive marks the current section as a conditionally linked sec-
tion. This section will be linked into the final output of the linker only if it is
referenced by a linked section through a symbol reference. By default, all
sections are linked.

Download from Www.Somanuals.com. All Manuals Search And Download.
Release Enhancements
The section in which the entry point of a C program is defined cannot be
marked as a conditionally linked section. The compiler marks all function
veneers as conditionally linked.
You must link with the –a linker option, which creates an absolute, execut-
able output module, to enable conditional linking. The –j linker option
disables conditional linking.
For information on the .clink directive, see the Assembler Directives
chapter of the TMS470R1x Assembly Language Tools User’s Guide; for
information on the –j linker option, see the Linker Description chapter.
C compiler enhancements
The TMS470R1x optimizing C compiler enhancements are as follows. For
more information, see the named chapter of the TMS470R1x Optimizing C
Compiler User’s Guide.
You can specify command line options in a file. When you specify that file
on the command line with the –@ shell option, the compiler reads the file
and interprets it as if it contained part of the command line. For more
information, see the Compiler Description chapter.
The options that invoke the interlist utility with the shell have changed. The
–s option interlists optimizer comments (if the optimizer is invoked) and
assembly statements; otherwise it interlists C source and assembly state-
ments. The–ssoptioninterlistsCsourceandassemblystatements. Anew
option, the –os option, interlists optimizer comments with assembly state-
ments. To interlist C source and assembly statements with optimizer
comments, use the –os and –ss options when invoking the optimizer. For
more information, see the Compiler Description and Optimizing Your
Code chapters.
Global register variables are now supported. For more information, see
the TMS470R1x C Language chapter.
Bit-field manipulation improvements are incorporated. For more informa-
tion, see the Runtime Environment chapter.
The alignment of structures has changed. In previous releases, all struc-
tures were word aligned. Now, a structure is aligned according to the align-
mentofthestructure’smostrestrictiveelement. Formoreinformation, see
the Runtime Environment chapter.
Software interrupts are supported for C code. You define the software
interrupt with the SWI_ALIAS pragma. For more information, see the
TMS470R1x C Language and Runtime Environment chapters.

Appendix A
Troubleshooting DOS Systems
DOS/4GW is a memory manager that is embedded into the DOS version of
the TMS470R1x code generation tools, so you may occasionally see
DOS/4GW error messages while you are using the tools. The executable files
for DOS/4GW are not shipped as such, nor is any documentation provided on
this tool, except for the list of error messages.
Section A.2, Kernel Error Messages, and Section A.3, DOS/4G Error Mes-
sages, are excerpted from the DOS/4GW User’s Manual (reproduced here
with the permission of Tenberry Software, Inc). Included are lists of error mes-
sages with descriptions of the circumstances in which the error is most likely
to occur and suggestions for remedying the problem. (Portions of the excerpt
have been modified to provide you with specific information about using TI
tools.)

Troubleshooting in the Protected-Mode Environment
A.1 Troubleshooting in the Protected-Mode Environment
Getting 32-bit programs to execute properly under DOS can be frustrating.
Your computer’s configuration and memory management can cause problems
that may be difficult to find because many programs are interacting.
This list of error messages is reproduced in Section A.2 on page A-5 and
Section A.3 on page A-9 because they may occur when you are executing
any tools, since all of the tools have been assembled along with the DOS/4GW
memory extender. When reading this material, consider these items:
When an Action directs you to technical support, determine the configura-
tion of your system by using the PMINFO program (on page A-3) before
contacting technical support. See the If You Need Assistance section on
page vi, for information about contacting technical support.
Some error messages are not included in this appendix because they are
rarely seen when using DOS/4GW with the TMS470R1x tools. Also, many
of the messages that are documented here are seldom seen when using
DOS/4GW with the TMS470R1x tools.

Troubleshooting in the Protected-Mode Environment
The PMINFO32.EXE program
Purpose:
Run PMINFO.EXE to determine the performance of protected/
real-mode switching and extended memory.
Notes:
The time-based measurements made by PMINFO may vary
slightly from run to run.
If this error message appears:
DOS/16M error: [17] system software does not follow VCPI
or DPMI specifications
check for a statement in your CONFIG.SYS containing
NOEMS. If such a statement exists, remove it and reboot your
computer.
If the computer is not equipped with extended memory or if
none is available for DOS/4GW, the extended-memory
measurements do not display.
Other DOS/4GW error messages are in Section A.3, DOS/4G
Error Messages.
Example:
The following example shows the output of the PMINFO pro-
gram on an 80486 AT -compatible machine running at
33 MHz.

Purpose
CPU performance
Shows the CPU processor equivalent and the speed of the CPU (in MHz)
According to BIOS
Shows the configured memory in DOS and extended memory as provided by the
BIOS (interrupts 12h and 15h, function 88h)
SETUP
Shows the configuration obtained directly from the CMOS RAM as set by the com-
puter’s setup program. It is displayed only if the numbers are different from those
in the BIOS line. They are different if the BIOS has reserved memory for itself or
if another program has allocated memory and is intercepting the BIOS configura-
tion requests to report less memory available than is physically configured.
DOS/16M programs
Transfer rates
If displayed, shows the low and high addresses available to DOS/4GW in
extended memory
PMINFO tries to determine the memory architecture. Some architectures perform
well under some circumstances and poorly under others; PMINFO shows the best
and worst cases. The architectures detected are cache, interleaved, page-mode
(or static column), and direct.
Measurements are made by using 32-bit accesses and are reported as the num-
ber of megabytes per second that can be transferred. The number of wait states
is reported in parentheses. The wait states can be a fractional number, like 0.5,
if there is a wait state on writes but not on reads. Memory bandwidth (that is, how
fast the CPU can access memory) accounts for 60% to 70% of the performance
for typical programs (those that are not heavily dependent on floating-point math).
Overall CPU and memory
performance
Shows a performance metric developed by Tenberry Software, Inc. (formerly
knownasRationalSystems, Inc.), indicatingtheexpectedthroughputforthecom-
puter relative to a standard 8-MHz IBM PC/AT (disk accesses and floating-point
operations are both excluded).
Protected/real switch rate
Shows the speed with which the computer can switch between real and protected
modes, both as the maximum number of round-trip switches that can occur per
second, and as the time for a single round-trip switch, broken into the real-to-
protected (up) and protected-to-real (down) components.

Kernel Error Messages
A.2 Kernel Error Messages
This section describes error messages from the DOS/16M kernel embedded
in the TMS470R1x code generation tools. Kernel error messages can occur
because of severe resource shortages, corruption of the executable file, cor-
ruption of memory, operating system incompatibilities, or internal errors. All of
these messages are quite rare.
DOS/16M protected mode available only with 386 or 486
Description
DOS4G did not detect the presence of a 386-, 486-, or Pen-
tium-based processor.
Action
If you are running the tools on a 386 (or later) PC, rerun the
program. If you are running the tools on a 286 PC, reinstall
and run the tools on a 386 PC or later.
0: involuntary switch to real mode
Description
The computer was in protected mode but switched to real
mode without going through DOS/16M. This error most often
occurs because of an unrecoverable stack segment
exception (stack overflow) but can also occur if the global
descriptor table or interrupt descriptor table is corrupted.
Action
Restart your computer. If the problem persists, contact tech-
nical support.
2: not a DOS/16M executable <filename>
Description
DOS4G.EXE or a bound DOS/4G application has probably
been corrupted in some way.
Action
Recopy the file from the source media.
6: not enough memory to load program
Description
Action
There is not enough memory to load DOS/4G.
Make more memory available and try again.
8: cannot open file <filename>
Description
The DOS/16M loader cannot load DOS/4G, probably
because DOS has run out of file units.
Action
Set a larger FILES= entry in the CONFIG.SYS file, reboot,
and try again.

Kernel Error Messages
17: system software does not follow VCPI or DPMI specifications
Description
Some memory-resident program has put your 386 or 486
CPU into virtual 8086 mode. This is done to provide special
memory services to DOS programs, such as EMS simulation
(EMS interface without EMS hardware) or high memory. In
this mode, it is not possible to switch into protected mode
unless the resident software follows a standard that
DOS/16M supports (DPMI, VCPI, and XMS are the most
common).
Action
Contact the vendor of your memory-management software.
22: cannot free memory
Description
Memory was probably corrupted during execution of your
program.
Action
Make more memory available and try again.
23: no memory for VCPI page table
Description
Action
There is not enough memory to load DOS/4G.
Make more memory available and try again.
24: VCPI page table address incorrect
Description
Action

DOS/4G Error Messages
A.3 DOS/4G Error Messages
DOS/4G errors are more common than kernel errors when using DOS/4G or
DOS/4GW with the TMS470R1x code generation tools. They are usually re-
lated to an unknown path name, corrupt files, or memory problems. Memory
problems can include inadequate memory, poor configuration, or corrupted
memory.
1000 ”can’t hook interrupts”
Description
Action
A DPMI host has prevented DOS/4G from loading.
Contact technical support.
1001 ”error in interrupt chain”
Description
Action
A DOS/4G internal error was detected.
Contact technical support.
1003 ”can’t lock extender kernel in memory”
Description
DOS/4G could not lock the kernel in physical memory, prob-
ably because of a memory shortage.
Action
Free some memory for the DOS/4G application.
1005 ”not enough memory for dispatcher data”
Description
There is not enough memory for DOS/4G to manage user-
installed interrupt handlers properly.
Action
Free some memory for the DOS/4G application.
1007 ”can’t find file <program> to load”
Description
DOS/4G could not open the specified program. The file prob-
ably does not exist. It is possible that DOS ran out of file han-
dles or that a network or similar utility has prohibited read ac-
cess to the program.
Action
Make sure that the filename was spelled correctly.
1008 ”can’t load executable format for file <filename> [<error
code>]”
Description
DOS/4G did not recognize the specified file as a valid execut-
able file. DOS/4G can load linear executables (LE and LX)
and EXPs (BW).
Action
Recopy the file from the source media.

3301 ”unhandled EMPTYFWD, GATE16, or unknown relocation”
3302 ”unhandled ALIAS16 reference to unaliased object”
3304 ”unhandled or unknown relocation”
Description
If your program was built for another platform that supports
the LINEXE format, it may contain a construct that DOS/4G
does not currently support, such as a call gate. One of these
messages may also appear if your program has a problem
mixing 16- and 32-bit code. A linker error is another likely
cause.
Action
Check for viruses and reinstall the tools from the source
media. If the problem persists, contact technical support.

A
C
asm470: The name of the command that invokes the assembler for the
TMS470R1x.
assembler: A software program that creates a machine-language program
from a source file that contains assembly language instructions, direc-
tives, and macro definitions. The assembler substitutes absolute opera-
tion codes for symbolic operation codes and absolute or relocatable
addresses for symbolic addresses.
C compiler: A software program that translates C source statements into
assembly language source statements.
code generator: A compiler tool that takes the file produced by the parser
or the optimizer and produces an assembly language source file.
COFF: Common object file format. A binary object file format that promotes
modular programming by supporting the concept of sections. All COFF
sections are independently relocatable in memory space; you can place
any section into any allocated block of target memory.
cl470: The name of the command that invokes the compiler shell program
for the TMS470R1x. (The second character in the shell name is a lower-
case L.)
D
DOS/4G: The base version for DOS/4GW. You may occasionally see this
term in an error message. If so, see Appendix A, Troubleshooting DOS
Systems, for the appropriate action.

Glossary
DOS/4GW: A memory extender that is bound with the DOS version of the
TMS470R1x code generation tools. The executable DOS/4GW file is not
shipped separately but is embedded within the other executables. Error
messages from DOS/4GW are included in Appendix A, Troubleshooting
DOS Systems, to assist you in debugging. If you receive one of these
errormessages, contacttechnicalsupportforassistance, andremember
that the tools are shipped as object files with the memory extender
embedded.
DOS/16M: The executable filename for a tool that is embedded in the
TMS470R1x code generation tools. You may occasionally see this term
in an error message. If so, see Appendix A, Troubleshooting DOS
Systems, for the appropriate action.
E
I
environment variables: System symbols that you define and assign to a
string. They are usually included in batch files (for example, .cshrc).
interlist utility: A compiler utility that inserts as comments your original C
source statements into the assembly language output from the assem-
bler. The C statements are inserted next to the equivalent assembly
instructions.
L
linker: A software program that combines object files to form an object mod-
ule that can be allocated into system memory and executed by the de-
vice.
lnk470: The name of the command that invokes the linker for the
TMS470R1x.
O
optimizer: A software tool that improves the execution speed and reduces
the size of C programs.
options: Command parameters that allow you to request additional or
specific functions when you invoke a software tool.

Glossary
P
pragma: Preprocessor directive that provides directions to the compiler
about how to treat a particular statement.
protected-mode programs: 32-bit extended DOS programs. These
programs require an extended memory manager and run on 80386,
80486, andPentiumbasedPCsonly. Protected-modeprogramscanuse
all available RAM on a computer up to 64M bytes.
R
S
real-mode: 16-bit native DOS mode. This mode limits the available memory
to 640K bytes. Calls to DOS may involve switching from protected to real
mode. DOS real-mode tools are no longer supported by the TMS470R1x
code generation tools.
shell program: A utility that lets you compile, assemble, and optionally link
inonestep. Theshellrunsoneormoresourcemodulesthroughthecom-
piler (including the parser, optimizer, and code generator), the assem-
bler, and the linker.
structure: A collection of one or more variables grouped together under a
single name.
swap file: The file where virtual memory (secondary memory) is allocated
on the hard disk.
V
veneer: A sequence of instructions that serves as an alternate entry point
into a routine if a state change is required.
virtual memory: The ability of a program to use more memory than a
computer actually has available as RAM. This is accomplished by using
a swap file on disk to augment RAM. When RAM is not sufficient, part of
the program is swapped out to a disk file until it is needed again. The
combination of the swap file and available RAM is the virtual memory.
The TMS470R1x tools use the DOS/4GW memory extender to provide
virtual-memory management (VMM). This memory extender is not pro-
vided as an executable file but is embedded in several of the tools
shipped by TI. Contact technical support for more information.
