The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=cf97d2a1dab8f2cddc4466fe64d37818339c73be commit cf97d2a1dab8f2cddc4466fe64d37818339c73be Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2021-02-23 20:03:32 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2021-02-23 20:10:01 +0000 Build lib/msun tests with compiler builtins disabled This forces the compiler to emit calls to libm functions, instead of possibly substituting pre-calculated results at compile time, which should help to actually test those functions.
