Suppose there is a main.cpp which depends on utils.cpp and static libraries static_A, and static libraries static_A depend on static libraries static_B, here static_A compile without -fno-omit-frame-pointer, but everything else with -fno-omit-frame-pointer, and the final generated binary, each static library and cpp Do functions in files have fr…
