- Support inline asm 'w' constraint for 128-bit vector types. - Also support the 'q' NEON registers asm code. llvm-svn: 90894

Handle ARM inline asm "w" constraints with 64-bit ("d") registers. The change in SelectionDAGBuilder is needed to allow using bitcasts to convert between f64 (the default type for ARM "d" registers) and 64-bit Neon vector types. Radar 7457110. llvm-svn: 91649

Remove arm_apcscc from the test files. It is the default and doing this matches what llvm-gcc and clang now produce. llvm-svn: 106221

Make tests register allocation independent again. llvm-svn: 129739

; CHECK: vmov.32 d30[0],
Change register allocation order for ARM VFP and NEON registers to put the callee-saved registers at the end of the lists. Also prefer to avoid using the low registers that are in register subclasses required by certain instructions, so that those registers will more likely be available when needed. This change makes a huge improvement in spilling in some cases. Thanks to Jakob for helping me realize the problem. Most of this patch is fixing the testsuite. There are quite a few places where we're checking for specific registers. I changed those to wildcards in places where that doesn't weaken the tests. The spill-q.ll and thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch of live values to force spills on those tests. llvm-svn: 116055
