问题
I have two static libraries named libx.a and liby.a.
libx.a is compiled with gcc -g; while liby.a is compiled with gcc -O3.
I want to link them two into a single executable.
Is it viable?
Is it harmful?
回答1:
Yes, it is viable, it isn't harmful as long as the optimizations don't change the ABI (of function calls, or of floating point arithmetic/representation, etc.). Although even in those cases, I believe all necessary information is already compiled in or the linker resolves the issues.
