--- Comment #5 from klondike klondike@klondike.es --- Created attachment 87543 --> https://bugs.freedesktop.org/attachment.cgi?id=87543&action=edit Expand most of the 64 bit operations into 32 bit ones
Well I have been messing a little bit with the TargetLowering. I have managed to get some operations to work (ANDs, ORs, XORs, UMULs, ADDS and SUBS amongst others) by forcing llvm to expand them.
DIVs are a completely different world since they require more advanced algorithms which I'm not familiar with or support for calls (plus porting gcc's functions). The first one I don't have time to do (for now) the second one is waaaaay out of my league.
The attached patch expands some of the 64 bit integer operations (but is still a WIP since likely most if not all (exceptions being loads and stores) need to be expanded and I haven't covered them all.
