--- Comment #5 from Dennis Camera <[email protected]> ---
Exactly the same SIGILL with openssl from ports:

> # /usr/local/bin/openssl version
> OpenSSL 3.0.18 30 Sep 2025 (Library: OpenSSL 3.0.18 30 Sep 2025)
> # lldb /usr/local/bin/openssl speed sha256
> (lldb) target create "/usr/local/bin/openssl"
> Current executable set to '/usr/local/bin/openssl' (powerpc64).
> (lldb) settings set -- target.run-args  "speed" "sha256"
> (lldb) r
> Process 26301 launched: '/usr/local/bin/openssl' (powerpc64)
> Doing sha256 for 3s on 16 size blocks: Process 26301 stopped
> * thread #1, name = 'openssl', stop reason = signal SIGILL: illegal opcode
>     frame #0: 0x00000008105c37c8
> ->  0x8105c37c8: vshasigmaw 30, 4, 1, 15
>     0x8105c37cc: vadduwm 7, 7, 30
>     0x8105c37d0: vxor   29, 0, 1
