...subtarget->isMachoABI() is true. > Alright, thx Evan, that's what I did. Here are the final patches I think can be committed. I tried to separate them into independent chunks, but I'm not sure how to do this in a good way because of CVS and since everything is kind of related. CallABIELF.patch file changes PPCISelLowering.cpp file for ELF ABI call support CalleeSavedLinuxPPC.patch changes the callee saved registers for function calls Creqv.patch adds some XLForm_1 classes to PPCInstrFormats.td for the CREQV instruction support Frame.patch modifies PPCFrameInfo.h to take into acc...

I think the easiest thing for you to do is to define a separate CALL instruction with a different set of Defs. This instruction should only be selected when the predicate isMacho is true. Also update PPCRegisterInfo.cpp getCalleeSavedRegs() to return a different list when subtarget->isMachoABI() is true. Evan On Feb 14, 2007, at 7:19 AM, Nicolas Geoffray wrote: > Hi Chris, >
