Aha! it is EH_RETURN :) and it appears stack adjustment is something different. for x86, gcc has: #define EH_RETURN_DATA_REGNO(N) ((N) <= DX_REG ? (N) : INVALID_REGNUM) thus N can either be AX_REG or DX_REG. (which is eax/rax and edx/rdx depending on compilation mode) for m68k gcc has: #define EH_RETURN_DATA_REGNO(N) \ ((N) < 2 ? (N) : INVALID_REGNUM) so that's registers d0 and d1 I'm guessing EHPersonality:CoreCLR is a different ABI that you're not concerned with.
Yeah, it also seems to be present in the X86 backend only (at least not in the Sparc backend).
Thus I think you want: getExceptionPointerRegister to return d0 and getExceptionSelectorRegister to return d1. give that a go, and see if you can throw/catch exceptions between code compiled by your llvm port and a gcc
Perfect, thanks.
hope that helps.
