The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=2fd73b7126d7d7e5701e001af929411ce7a0c5f1 commit 2fd73b7126d7d7e5701e001af929411ce7a0c5f1 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2024-04-18 17:46:57 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2024-04-18 18:42:21 +0000 share/mk/bsd.cpu.mk: add F16C feature for i386 and amd64 architectures As discussed in bug 278417, some ports require the F16C instruction set to compile, but there is no way yet to detect whether the currently chosen CPUTYPE supports this feature. Add the feature to the MACHINE_CPU variable, for each processor that supports it. The list of processors was extracted from clang 18's -dM output, filtered on the __F16C__ define.
