search for: _sse2

If someone knowledgable enough in > that area wants to fix it, though... My suggestion would be to have a get_checksum1_sse2() and get_checksum1_sse3() and always build them. The compiler should support it. Then on runtime you would check for sse3 and based on the result get_checksum1() would either invoke the _sse2() or sse3(). Without auto detection it won't be utilized by distros. But yes, this could be improved...

...ecause it disables -msse2 switch. Maybe it makes sense to add new switch, --no-force-sse2 or --disable-force-sse2 or similar? And replace if test "x$asm_optimisation$sse_os" = "xyesyes" ; then XIPH_ADD_CFLAGS([-msse2]) fi with if test "x$force_sse2" = "xyes" ; then XIPH_ADD_CFLAGS([-msse2]) fi ?

What do you base this on? Per https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html : "For the x86-32 compiler, you must use -march=cpu-type, -msse or -msse2 switches to enable SSE extensions and make this option effective. For the x86-64 compiler, these extensions are enabled by default." That reads to me like we're fine for SSE2. As stated in my comments, SSSE3 support must be

The attached patch cleans up Opus's x86 intrinsics configury. It: * Makes ?enable-intrinsics work with clang and other non-GCC compilers * Enables RTCD for the floating-point-mode SSE code in Celt. * Disables use of RTCD in cases where the compiler targets an instruction set by default. * Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in
