OpenBSD build*/mvm breakout

[KenDickey]

Added building/openbsd64* files. Tested builds on x86_64 & aarch64 OpenBSD
Cleaned OpenBSD refs from linux64x64 & linux64ARMv8 mvm's; also built & tested on x86_64 & aarch64 Linux.
Looks good to me.
We live in hope! 8^)

QNX RasPi5 self-hosted squeak.stack.spur build{,.debug,.assrtt} build & tests OK.
Rebuilt on Linux on x86_64 and aarch64 and on MaxOSarm64, so configure of
--with-vm-dislay-qnxScreen works.

OK to integrate AFAIKT.

nice

[KenDickey]

Also built & tested [cog] OK on OpenBSD on x86_64 and aarch64.
Also framebuffer OK on Alpine Linux [x86_64].
Please integrate!

[KenDickey]

Cog build & build.debug VMs build and run on QNX RPi5 self-hosted.

Built osvm on latest OpenBSD release [7.9] on both arm64 and x86_64.

Hi, Builds and runs well for me, though on arm64 I had to reduce the optimization from -O2 to -O1.  Odd not on x86_64. When I get more time I will look into why the compiler gets this wrong. cheers bruce

aarch64 OpenBSD 7.9 confirmed.
-O2 builds & works for stack interpreter
-O2 builds & segfaults for cog but cog works fine for -O1
Compiled with clang 19.1.7

Hmmm.. ??

[KenDickey]

Problem seems to exhibit from file "src/spur64.cog/cogitARMv8.c"

Could someone knowledgeable shed some light on this?

Note that OSVM cog builds & works on x86_64 and aarch64 (as well as on QNX aarch64).
I.e. All builds AOK AFAIKT
