Compiler 7.4.8 the output object is extremely huge

giorgos tsoumplekas

Dear all,

We have created a output object using the 7.4.8 compiler.

Although τhe size of the code  is 661 KB, the  total size of object is 21.8 MB. After execute the strip command the size 1.88 KB. 
 The symbolic debug options are enabled when  we compiler the whole project. 
How we can reduce the size of the executable?

Please find below the compiler setting and the linker setting.

Compiler options 
CCOPTS = -mv6600 --abi=eabi -q -mi10 -mo -pdr -pden -pds=238 -pds=880 -pds1110  --program_level_compile -o3 -g --optimize_with_debug 
  $(TI_BIN_CGTOOLS)/cl6x.exe -mv6600 --abi=eabi  $(CCOPTS) --disable_push_pop --gen_acp_raw --compile_only --display_error_number --diag_warning=225 --diag_wrap=off --cmd_file="$(VOB_ROOT_REL)/project/udp6654/cfg/udp6654/compiler.opt" -i$(VOB_ROOT_DIR)/project/udp6654/inc/sysbios

Linker options
$(TI_BIN_CGTOOLS)/cl6x.exe  --abi=eabi --run_linker --display_error_number -mv6600 --reread_libs --run_abs  --absolute_exe  --rom_model --trampolines=on

Thank in advance

The advice in this post does not apply to those using C6000 compiler version 8.0.0 or higher.

Consider removing the -g option on some of the source files. These would be files you are confident you don't need to single step, set breakpoints, etc. I am not certain this change will save you enough size to matter. But I think it is worth a try. Please let us know whether you try this experiment, and how it works out for you.

Thanks and regards,

On the same source files you build without -g, also add the option --symdebug:none. Please let us know whether this helps.

Thanks and regards,

May I ask why you need to reduce the size of the executable object file? It's not uncommon for this file to be much larger than the target footprint, and the executable size does not affect the target footprint.

Please run the command line utility ofd6x on the executable object file and post the output.

I'm sorry, I'm not seeing any sort of ofd6x output in the thread; you may need to try attaching the file again. You should be able to drag and drop the file right into your post
