[LLVMdev] Combining physical registers
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...
