mysql80-server 8.0.26 build output
I'm finding that on my FreeBSD 12.2-RELEASE-p7 amd64 system with dual Xeon
L5420s (Harpertown, which is Penryn microarchitecture), I'm unable to build
mysql80-server, as a SIGILL is thrown running routerfuzz_router_uri. I've tried
MAKE_JOBS_UNSAFE=yes with no changes, as well as adding CPUTYPE?=penryn to
/etc/make.conf.
I've attached the output from make trying to build the port.
After rebuilding the routerfuzz_router_uri binary that's deleted, and running
gdb on the core dump, I receive the following:
root@uncannyvalley:/usr/ports/databases/mysql80-server/work/.build/router/tests/fuzzers

popcnt is a Nehalem instruction, which obviously my Penryn CPU wouldn't have.
Looks like __sanitizer_cov_trace_const_cmp1 is a clang function - this may
actually be a clang bug (at least as FreeBSD supplies it), but we'll go with
mysql80-server as being the problem right now because that's the only thing I
can't build.
And my current /etc/make.conf:
WITH_PKGNG= yes
DEFAULT_VERSIONS+=ssl=openssl
MAKE_JOBS_NUMBER=9
#MAKE_JOBS_UNSAFE=yes
OPTIONS_UNSET= GSSAPI_BASE
OPTIONS_SET= GSSAPI_MIT
CPUTYPE?= penryn
And, for completeness, compiler info:
