Hi all, I'm trying to understand which ABIs are supported in the PowerPC backend and I'm getting a bit confused. Here's what I've gathered so far alongside with some questions. - In PPCSubtarget.h there's DarwinABI, SVR4ABI and ELFv2ABI. - The CodeGenerator documentation claims that the AIX PowerPC ABI is followed (with some deviations). Is this refering to the DarwinABI? - In a recent commit a TargetABI value and enumeration was added to PPCSubtarget which contains PPC_ABI_UNKNOWN, PPC_ABI_ELFv1 and PPC_ABI_ELFv2. Fo...
