Jakob Stoklund Olesen babf0569e2 Teach TableGen to infer missing register classes. ... The set of register classes should be closed under sub-register operations and intersections. That will allow the register allocator to model combinations of constraints accurately. This patch implements the easiest form of register class inference: For every register class, and for every sub-register SubIdx, the subset of registers in RC that have a SubIdx sub-register should also be a register class. This does create some new register classes for the targets in the tree: ARM gets a new QQQQPR_with_ssub_0. This class was omitted from the .td file on purpose because it only has two registers. InstrEmitter and RegisterCoalescer have safeguards against selecting too small register classes, so it is harmless. PowerPC gets a G8RC_with_sub_32 class because LR is not a sub_32 sub-register of LR8. I think that might be an omission? X86 puts RIP in the GR64 class, and since that register doesn't have 8-bit sub-registers, we get: GR64_with_sub_8bit GR64_TC_with_sub_8bit GR64_NOREX_with_sub_8bit GR64_TC_with_sub_8bit_hi The various CodeGen classes have already been fixed so adding new register classes should not affect compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141084 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-04 15:28:49 +00:00
