Compiler/TMS320C6670: How to build C6000 RTS library without optimization

Part Number: TMS320C6670
Other Parts Discussed in Thread: TI-CGT

Tool/software: TI C/C++ Compiler

Hello,

How do I build the C6000 RTS library (e.g. rts6600_elf.lib) without optimization?

For verification of our tool I need the library without SPLOOPs, and with varying optimization options (-O0 to -O3).

What's the fastest way to do this?

    Use the mklib utility.  It is located in the \lib directory of your compiler installation.  To get you started, I wrote this Windows batch file.  You need to tweak it to your specific installation.

    @echo off
rem -----------------------------------------------------------------------
rem Run this batch file in the directory where the new RTS library is to
rem be written
rem -----------------------------------------------------------------------

rem -----------------------------------------------------------------------
rem Do not remember the environment variables set in this file
rem -----------------------------------------------------------------------
setlocal

rem -----------------------------------------------------------------------
rem Set to location of the compiler installation
rem -----------------------------------------------------------------------
set cgtroot=C:\ti\ccsv8\tools\compiler\ti-cgt-c6000_8.2.3

rem -----------------------------------------------------------------------
rem Set to desired optimization level.  Affects build options and the
rem name of the library built.
rem -----------------------------------------------------------------------
set olev=0

rem -----------------------------------------------------------------------
rem No need to modify
rem -----------------------------------------------------------------------
set lib=%cgtroot%\lib

rem -----------------------------------------------------------------------
rem Invoke mklib
rem -----------------------------------------------------------------------
@echo on
%lib%\mklib --pattern=rts6600_elf.lib --extra_options="--opt_level=%olev% --disable_software_pipeline" --index=%lib%\libc.a --install_to=. --name=rts6600_elf_opt%olev%.lib

    Thanks and regards,

    Hello,

    After additionally setting the PATH variable to utils/bin and utils/cygwin

    set PATH=C:\Users\user\ccsv8\utils\bin;C:\Users\user\ccsv8\utils\cygwin

    I get the following error:

    The compiler executables also need to be in the PATH.  I'm sorry I didn't tell you this before. In your case, add this ...

    C:\Users\user\ccsv8\tools\compiler\ti-cgt-c6000_8.2.4\bin

    ... to the PATH.

    Thanks and regards,

    -George
