Part Number: TMS570LS0714
Tool/software: TI C/C++ Compiler
My customer use TMS570LS0714 ,customer met issue that the compiling time too long.
The detail as below:
LS0714 project compiling time around 50 minutes to rebuild(Build All) the project, while similar project which use Infineon Tri-core just used 10minute for rebuild(Build All),
CCS and compiler condition:
Compiler version: 5.0.4
-mv7R4 --code_state=32 --float_support=VFPv3D16 --abi=eabi -O3 -g --define=_TMS570LS07x_ --define=_VFP_SUPPORT_=1 --diag_warning=225 --diag_warning=16004 --display_error_number --diag_wrap=off --enum_type=packed --asm_listing --obj_directory="BSW/src/BSW/Gen/Dcm/src"
4.Customer already select “enable parallel build –Use optimal jobs(4)” option.
5.Customer cannot try the new LTS version compiler due to below reason:
a. The EATS OS limited the compiler version to 5.1.0 or more old version. If use the LTS version compiler , the OS will cannot compiler.
b. Customer project with ISO26262 ASIL-C requirement, the SDL CSP and MCAL CSP are based on 5.0.4 compiler.
The project with AUTOSAR ,OS,MCAL and application SW. When select “ Rebuild Project “ operation, will need around 50 minutes to finish TMS570 project compiling and generate the .out file. And most time are spend on the build stage and link time is very short .
Customer has similar project which used Infineon TC23x, the project also with AUTOSAR ,OS ,MCAL and application SW, with the same computer ,use Tasking environment to rebuild project just need 10minutes.
We really need you help to look into this issue and help to reduce the compiling time.
Please consider these two possible solutions.
The CCS indexer might take a long time. To learn about the indexer, why it might be the problem, and how to disable it, please see the indexer part of the larger article CCS Project and Build Handbook.
It might be the case that one or two very large functions take a lot of build time. Working through this issue requires finding the largest functions, then either making those functions smaller, or building them with lower optimization.
To find the largest functions, start by using a command similar to ...
% armofd --func_info final_executable.out > size_data.csv
armofd is the Object File Display utility. It is a command line utility that is part of the ARM compiler installation. It is documented in the ARM assembly tools manual. The option --func_info causes it to emit one line of information about each function in the program. The input in the example is final_executable.out. Replace that with the final executable file created by the linker. The output is written to a file named size_data.csv.
To understand what is in size_data.csv, here are 3 typical lines ...
The information is in comma separated values (CSV) format. The fields are function name, source file name, start address, end address, size. A CSV file can be directly loaded into a spreadsheet application like Excel. Then sort on the size column (the last one). Focus your attention on the first few functions.
Rebuild just one of those source files. In CCS, select the file, right click, then choose Build Selected File(s). If the build of that one file takes a long time, then you have found the problem. Or, maybe a big part of the problem.
Once the problem function, or functions, is found, consider splitting the function into multiple smaller functions. Or, perhaps lower the optimization used when building just this one source file. For details, see the File Specific Options part of the build handbook.

In reply to Huihuang Chen:
Huihuang ChenCould we provide one MCAL example project which "rebuild all "compiling time is around one mintue
That sounds like a good idea. But I am concerned about one thing. If this project needs other software packages to be installed on the system, that increases the risk I will not be able to build the project. I have experienced failure to build before. In that case, an example project depended on other software packages, and I could not work out what packages, what version, where they should be installed, and other such configuration details.
So, it is ideal if the project is self-contained. If that is not practical, then please tell me what software packages are needed, where to download them, what version, where they should be installed, and any other such detail that might be needed.
To package up the project, please use the directions in the article Project Sharing.
I think the project is self contained.you just need to install ARM compiler.
