UPDATE:
I have successfully tested:
-- aarch64 (Qemu aarch64)
-- amd64 (x86_64 VMware VM)
-- arm (Qemu arm; tested armv3[no ldrh] and armv4[yes ldrh] code paths
-- i386 (x86 VMware VM)
-- sparc (Qemu sparc)
I have setups to test, but am having troubles with:
-- sparc64 -- but Qemu is giving me trouble with disk / network, so
need to get that fixed first
-- vax -- but my SIMH network setup stopped working, so I need to
figure that out
-- mips -- but gxemul doesn't seem to have good host networking
capabilities, and evbmips MALTA hangs in Qemu when attaching gt0
Platforms where a good emulation environment seems to exist, but I haven't set
one up yet:
-- powerpc (Qemu?)
Platforms I need help with due to lack of good emulation environments:
-- alpha (I have no clue how well SIMH's alpha simulator works)
-- hppa (Qemu doesn't support system emulation of hppa)
-- m68k (no good simulation environment that I can run, AFAICT)
-- sh3 (seems we don't support the boards that Qemu emulates, and also
lack of networking in gxemul Dreamcast emulation)
And in the WTF category:
-- or1k -- port is incomplete
-- riscv -- port is incomplete
-- ia64 -- I decided to accept the pain and learn some ia64 assembly,
but I don't know the state of the port, so... ?
-- usermode ... ??
ia64 compiles, at least.
So, any volunteers who can help me test alpha, hppa, m68k, and sh3? Let's
start with those for now, since I don't have any clear path to test them myself.
Thanks!
