Hi, thanks for the information, but LLVM still does not provide ABI compatibility. If you reduce the struct to 3 i32, it is passed in edi, esi, and edx on my machine. However according to the ABI it should be packed in rdi and rsi. Checkout the QBE transcription and what it will compile to http://c9x.me/paste/mGOO http://c9x.me/paste/mGOO (there is a bit of register shuffling because hinting in regalloc is not very mature yet, but note that SSA form for the input is not required!).
