Bootstrap on Darwin x86_64 is broken on at least AVX512 and i5 cpus at revision r12-3311-g1e6267b33526. "fp-machine.h:81:22: error: unknown type name 'TFtype'; did you mean 'HFtype’?” any immediate ideas on what might be the issue? thanks Iain > > On Mon, Aug 2, 2021 at 2:31 PM liuhongt <hongtao....@intel.com> wrote: >> >> Update from v2: >> >> 1.
