Thanks for showing interesting:) (At least let me know I am not wasting my energy.) Posted D102453 <https://reviews.llvm.org/D102453> for the GCC optimization. Personally I always build llvm-project with a stable Clang so D102453 <https://reviews.llvm.org/D102453> doesn't really make my life better. D102453 <https://reviews.llvm.org/D102453> is for those distributions which build llvm-project with GCC... When building Linux kernel, I don't see additional improvement by adding -fno-semantic-interposition, but it does make libLLVM.so 2% smaller (notably, GCC -fPIC -fno-semantic-interposition can optimize some functions which call other non-inline functions so in various places the function body can be smaller. Some vtable can be optimized out as well.)
