Those sysctl names are probably wrong. On a Broadwell system, only |
| features->sse4_1 = GetDarwinSysCtlByName("hw.optional.sse4_1"); | ||
| features->sse4_2 = GetDarwinSysCtlByName("hw.optional.sse4_2"); | ||
| #elif defined(CPU_FEATURES_OS_FREEBSD) | ||
| features->sse = sysctlbyname("hw.instruction_sse", NULL, NULL, NULL, 1); |

As far as I understand, this is not how sysctlbyname is supposed to be used.
https://www.freebsd.org/cgi/man.cgi?query=sysctlbyname&manpath=FreeBSD+13.0-RELEASE+and+Ports
One need to set proper arguments.
Also returned value is 0 upon success and -1 upon failures.
I believe we should rename GetDarwinSysCtlByName above and use it here.

This should probably be merged with the Darwin logic above.

I'm closing this PR, FreeBSD support will be handled by #163 which will be submitted as soon as we have FreeBSD support in our CI. Thank you @mldulaney for the patch: it didn't make it to the repo but it got me interested in solving the issue so it's a worthwhile contribution! (also thank you @vishwin for the comment) |

This patch introduces support for x86 on FreeBSD. I note that I added the check for FreeBSD on aarch64 to fail in case this gets built on an aarch64 FreeBSD system.
