[LLVMdev] Invalid or unaligned stack exception on Windows
...on the source code, it looks like you are
allocating stack manually, but I could be wrong.
What triple are you using with LLVM to generate code?
There isn't much else information here, but you can try to zero in on the
problem by checking the stack alignment manually with a helper like:
void CheckAlignment() {
assert((((uintptr_t)_AddressOfReturnAddress() + 8) & 15) == 0);
}
Run this near where LLVM calls back into C code. If it fails, disassemble
the calling LLVM function and look at that to see if there's something
wrong with the prologue. Sending that along with any followups would be

[LLVMdev] Invalid or unaligned stack exception on Windows
Hi,
I wrote sometime ago about this issue (see links below).

At the time I thought the problem was due to a bug in my code, and
that I had fixed it. But sadly it seems that the issue is still
present - it just got hidden by whatever change I made.

Alright, let's be specific. PPC64TargetInfo::relocateOne in tools/lld/ELF/Target.cpp has this:
switch (Type) {
case R_PPC64_ADDR14: {
checkAlignment<4>(Val, Type);
// Preserve the AA/LK bits in the branch instruction
uint8_t AALK = Loc[3];
write16be(Loc + 2, (AALK & 3) | (Val & 0xfffc));
break;
}
case R_PPC64_ADDR16:
checkInt<16>(Val, Type);
write16be(Loc, Val);
break;
case R_PPC64_ADDR16_DS:
checkInt<16>(Va...
