https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227339 Dimitry Andric <dim@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dim@FreeBSD.org --- Comment #2 from Dimitry Andric <dim@FreeBSD.org> --- This also reproduces with clang from head: /usr/ports/databases/arangodb33/work/arangodb-3.3.6.1/3rdParty/curl/curl-7.= 50.3/lib/timeval.c:137:8: error: SSE2 register return with SSE2 disabled double curlx_tvdiff_secs(struct timeval newer, struct timeval older) ^ 1 error generated. and I think the problem is that the command line options make it impossible= to compile this source. E.g. it compiles for amd64, but something passes: -mno-sse2 -mno-sse3 -mno-ssse3 -mno-sse4.1 -mno-sse4.2 -mno-sse4a -mno-avx -mno-fma -mno-bmi2 -mno-avx2 -mno-xop -mno-fma4 -mno-avx512f -mno-avx512vl -mno-avx512pf -mno-avx512er -mno-avx512cd -mno-avx512dq -mno-avx512bw -mno-avx512ifma -mno-avx512vbmi on the command line, making it impossible to work with doubles in the amd64 ABI. You should try removing all the -mno-* options, and see if it compiles then. --=20 You are receiving this mail because: You are the assignee for the bug.=
