Hi Job, > This issue is basically that I cannot find a way to distinguish two i16 > arguments from one i32. Is there a way to do this in LLVM? Preferably using > tablegen, of course:-) I think the property you want is "isSplit" (or, from the TableGen side CCIfSplit). This gets applied to the first of those i16s that are produced. Unfortunately I can't think of much you can do from TableGen to swap the registers around (CCIfSplit is useful if the i32 would have to start at an even-numbered register, for example). But in the C++ ISelLowering code you can u...

I'm currently working on the MSP430 backend and I have some problems implementing the calling convention. It's a 16-bit architecture which dictates that arguments should be passed in registers R15-R12. Therefore, I have something like this is a .td file: CCIfType<[i16], CCAssignToReg<[R15W, R14W, R13W, R12W]>> 32-bit arguments should be passed in R14:R15 (R12:R13).

Attached is a working patch set for llvm to be able to emit arm64 (currently as triple aarch64-apple-ios) mach-o object files, in case someone is interested. I'm not sure if the llvm maintainers want the patch given the previous message that there's going to be an official patch set from apple to support this, but here is mine. What works (tested on an iPhone 5S): * objc strings,
