https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D262857 --- Comment #5 from Jan Beich <jbeich@FreeBSD.org> --- (In reply to Robert Clausecker from comment #4) Setting CPUTYPE via make.conf(5) has the same effect. -Dsse2=3Dfalse in mes= a-* simply removes -msse2 -mfpmath=3Dsse. FreeBSD i386 uses Clang, so -msse2 im= plies -mfpmath=3Dsse while -march=3Dpentium4 or greater implies -msse2. $ cc -msse2 -mfpmath=3D387 -dM -E -</dev/null | fgrep SSE2 error: the '387' unit is not supported with this instruction set $ cc -march=3Dpentium4 -dM -E -</dev/null | fgrep SSE2 #define __SSE2_MATH__ 1 // aka -mfpmath=3Dsse #define __SSE2__ 1 // aka -msse2 $ gcc12 -march=3Dpentium4 -dM -E -</dev/null | fgrep SSE2 #define __SSE2__ 1 // aka -msse2 --=20 You are receiving this mail because: You are the assignee for the bug.=
