The branch main has been updated by cognet: URL: https://cgit.FreeBSD.org/src/commit/?id=c328f64d81079bad5064c8a387883df50ab5aaed commit c328f64d81079bad5064c8a387883df50ab5aaed Author: Olivier Houchard <cognet@FreeBSD.org> AuthorDate: 2021-03-10 18:01:41 +0000 Commit: Olivier Houchard <cognet@FreeBSD.org> CommitDate: 2021-03-10 18:06:42 +0000 arm64: Fix COMPAT_FREEBSD32. The ENTRY() macro was modified by commit 28d945204ea1014d7de6906af8470ed8b3311335 to add an optional NOP instruction at the beginning of the function. It is of course an arm64 instruction, so unsuitable for the 32bits sigcode. So just use EENTRY() instead for aarch32_sigcode. This should fix receiving signals when running 32bits binaries on FreeBSD/arm64.
