Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- And it is an intentional disto decision, because 32-bit kernels aren't supported (not even shipped) in RHEL and thus SSE2 is required. You can always use -march=i386 or -mno-sse etc. to override the defaults. E.g. in Fedora 32-bit CPUs are still supported and the configured compiler defaults to -march=i686 for 32-bit compilation.
