When i find information about reduce execution size, i found that in compilers like tiarmclang( https://software-dl.ti.com/codegen/docs/tiarmclang/rel1_3_0_LTS/compiler_manual/linker_description/08_using_linker_generated_copy_tables/compression-stdz0754720.html) and IAR,there are options provided to compress segments of execution(data,text..etc). usually i use gcc and clang compiler, are there similar options to compress the segments of execution? I only found compress options for debug information in clang compiler. thx A curious man:cora
