LLVM Virtual registers after RA pass?
...ementations (including ARM Thumb) create virtual registers in ‘eliminatedFrameIndex’. What am I missing?, is there something that I need to set for virtual registers to be allowed after the RA pass, and specifically in the ‘eliminateFrameIndex’ function?

How to change CLang struct alignment behaviour?
My target implementation has 2 byte (16 bit ints) For my target implementation I would want that Clang would always use 2 byte aligned padding for Structs, which would match the size of an int. The current situation is that for this struct: struct AA { char n; char m; char j; }; I get it aligned by 1: %a = alloca %struct.AA, align 1 I would want it to implicitly use 4 bytes

How to change CLang struct alignment behaviour?
...icks such as shifts and byte-swaps, when trying to replace struct ‘memcpy’s by word sized load/store instructions. For 16 bit aligned structs the ‘memcpy’ replacement code is much cleaner. That’s the reason I would want structs to be always 16 bit aligned/padded.
