Hi all, I first want to make it clear that I am not asking for "support" but just asking if someone can point me in the right direction.ยจ
I've been playing with compiling the system with CPU specific flags for example: COPTS += -march=znver1 -mtune=znver1 CXXOPTS += -march=znver1 -mtune=znver1 Which for the base system seems to be fine so far, but for some ports such as devel/gcc/* math/cblas it seems that the compiler/linker (or whatever beyond my knowledge) fails with CPU instructions that don't exist. Such as this: Error: no such instruction: `vmovsd %xmm0,8(%rsp)' This is fine, I am just trying to learn, but what I would like is if someone can point me in the right direction to specify global COPTS/CXXOPTS/CFLAGS/CXXFLAGS/etc but unset them for specific ports. Or.. How to let these builds know that these instructions do exist would be even more nice.. :-) Any insight? Thanks, Justin
