Instead, we have large switch statements like getARMRegisterNumbering(). Actually, I think it might be useful to have TableGen handle the register encoding numbering, just like it does for DWARF register numbers. /jakob --------------...

The function TII::canCombineSubRegIndices has been gone for a while now, and I was wondering if there is a target-independent way of determining if a certain set of physical registers "adds up" to a larger register. For example, on X86, AL and AH together form AX. On Hexagon, R0 and R1 are D0. The context here is an attempt to coalesce multiple loads/stores into fewer loads/stores

Hello, I would like to know if there's a way of setting the callee-saved register list inside getCalleeSavedRegs() to make the PEI pass save/restore only one half of a register pair if the other half is not being used, instead of saving the whole pair. Here is an example of what I try to explain to make things more clear: Suppose this situation where we have a register file of 8bit regs, and
