Tim Northover 5eefec9e6d AArch64: use RegisterOperand for NEON registers. ... Previously we modelled VPR128 and VPR64 as essentially identical register-classes containing V0-V31 (which had Q0-Q31 as "sub_alias" sub-registers). This model is starting to cause significant problems for code generation, particularly writing EXTRACT/INSERT_SUBREG patterns for converting between the two. The change here switches to classifying VPR64 & VPR128 as RegisterOperands, which are essentially aliases for RegisterClasses with different parsing and printing behaviour. This fits almost exactly with their real status (VPR128 == FPR128 printed strangely, VPR64 == FPR64 printed strangely). llvm-svn: 190665		2013-09-13 07:26:52 +00:00
