To do so, simply add these init files to X86ASM-OBJS instead of OBJS in the Makefile. The former is already used for the actual assembly files, but using them for the C init files just works, because the build system uses file extensions to derive whether it is a C or a NASM file. This avoids compiling unused function stubs and also reduces our reliance on DCE: We don't add %if checks to the asm files except for AVX, AVX2, FMA3, FMA4, XOP and AVX512, so all the MMX-SSE4 functions will be available. It also allows to remove HAVE_X86ASM checks in these init files. Reviewed-by: Kacper Michajłow <kasper93@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
