See details in the llvm bug (see URL). FreeBSD 13.1-STABLE
(In reply to Yuri Victorovich from comment #0) This gives a little bit of local information about the specific error from my trying the reproducer. My information has backtraces as I build even non-debug style without stripping symbols. Relative to potential llvm14 status, it reports: error: unknown argument: '-munwind-tables' On 13.1, using its llvm13 context, I see things like: # . ./scalaraccess-7a4b7b.sh /disk-samsung/freebsd-ports/devel/vc/work/Vc-1.4.3/tests/scalaraccess.cpp:33:1: error: SSE2 register return with SSE2 disabled TEST_TYPES(V, reads, concat<AllVectors, SimdArrayList>) ^ . . .
