Unfortunately I use poudriere to build a local package reposi= tory on my fastest machine and install packages on all other machines on my netw= ork. My build machine has AVX-512 instructions, the machine I want to run the co= de on doesn't and crashes with an illegal instruction when it hits a vxorps opcode. The ports Makefile has no option to control whether or not optimised code is used, that depends only on the actual hardware used for the build. It needs= an option to disable use of the optimised code. I've got a quick hack to the Makefile that works, but don't know if it's of suitable quality for ports. = The diff is attached. I reused the standard SIMD option as the control. --=20 You are receiving this mail because: You are the assignee for the bug.=
