Hi, This drops -ffreestanding for i386 unconditionally for GCC, and on Clang version 16 and later. FORTIFY_SOURCE depends on the libcall optimizations made without -ffreestanding on Clang. On GCC, there is no expected differences. With that done, it's possible to gain Clang FORTIFY_SOURCE coverage on i386 again, though only for Clang 16+.
