[LLVMdev] Strange behaviour with x86-64 windows, bad call instruction address
...FFFC5121A je 000007FFFFC511C3
000007FFFFC51220 mov qword ptr [rbp-68h],rdi
000007FFFFC51224 mov eax,10h
000007FFFFC51229 call 0000080077B3F1D0
000007FFFFC5122E sub rsp,rax
000007FFFFC51231 mov rdx,rsp
000007FFFFC51234 mov qword ptr [rbp-0F0h],rdx
000007FFFFC5123B sub rsp,20h
The call instruction at 000007FFFFC51229 is the one that jumps into invalid memory at 80077B3F1D0. I'm not sure why this particular EXE causes llvm to use such large address values, but it looks like there might be some 32 bit vs 64 bit address calc...

[LLVMdev] SIMD instructions and memory alignment on X86
Hmm, I'm not able to get those .ll files to compile if I disable SSE and I
end up with SSE instructions(including sqrtpd) if I don't disable it.
