Hi Everyone, I'm trying to use SSE2 and SSSE3 intrinsics on some old hardware. The program performs its own CPUID checks, so it knows when it can enter a particular code path. The program is compiled with -march=native, but the machine lacks SSSE3 and above. It causing the compile to fail. I recall seeing a GCC bug report that enabled intrinsics all time, regardless of the machine's features. I can no longer locate the bug report, so I don't know which version of GCC supports the feature. My question is, which version of GCC supports intrinsics independent of -mXXX? Thanks in advance.
