All the object files in the stage 2 build directory are aarch64, except
the GHC binary itself; now, I don't know why this happens, but this line
seems a little weird in hadrian/src/Rules/Program.hs:
-- For cross compiler, copy @stage0/bin/<pgm>@ to @stage1/bin/@.
Anyway, with the hello world program I mentioned I built using stage 1,
I ran it with LLDB in the OpenBSD/arm64 machine, and it segfaults here:
(lldb) run
Process 66875 launched: '/home/habib/hello' (aarch64)
Process 66875 stopped
* thread #1, stop reason = signal SIGSEGV
frame #0: 0x0000000000a2c3a0 hello`stg_enter_info + 24
hello`stg_enter_info:
-> 0xa2c3a0 <+24>: ldur w15, [x17, #-0x8]
0xa2c3a4 <+28>: sxtw x15, w15
0xa2c3a8 <+32>: mov x14, #0x1a
0xa2c3ac <+36>: cmp x15, x14
(lldb)
I saw an old ticket for macOS where it errors on the line before the
ldur (which you can't see here), because it accesses the reserved x18
register, so I thought maybe something similar is going on with OpenBSD
where,
due to GHC not yet having tested or even specifically designed for, the
OpenBSD/arm64 compilation target, maybe there's some OpenBSD-specific
thing that hasn't been accounted for that the OpenBSD devs know about.
If an OpenBSD dev wants to look at it, I can send the binary or an
assembly dump of it as an attachment, however you want. I can then let
the GHC developers know where their aarch64 output is wrong for OpenBSD.
I'll try using the LLVM backend to compile the hello world program,
since that obviously supports OpenBSD/arm64, so I don't see it
outputting incorrect assembly for a hello world program for that target.
I might or might not keep working on this today, but I'll try and get
back in with another progress update tomorrow evening.
Cheers,
Habib
