009318c5a9 Fix warnings when building with -DSDL_LIBC=OFF on Linux 2024-03-18 21:29:08 +01:00

cb3a1a82d5 SDL_memcpy.c, SDL_memmove.c, SDL_memset.c: don't use gcc builtins if !HAVE_LIBC 
__builtin_memcpy, as well as __builtin_memset and __builtin_memmove, needn't be
inlined but emitted as a libc call, leading to infinitely recursive calls.

7a069cc4b0 Allow optimizing memcpy and memset where possible 
Modern C runtimes have well optimized memset and memcpy, so use those instead of dispatching into SDL's versions. In addition, some compilers can analyze memset and memcpy calls and directly turn them into optimized assembly.

5da85376b9 stdlib: move all mslibc functions to SDL_mslibc.c 
This allows disabling LTO on them by only specifying a single file.

ae7446a959 stlib: Extract SDL_memcpy and SDL_memset to its own file respectively 
This is done such that we can disable LTO for these 2 functions when
building with MSVC.

This is due to a limitation of Link Time Code Generation (LTCG).
Code generation might generate a new reference to memset after linking
has started. The LTCG must make assumptions about where memset is
defined which is normally the C runtime.
