Jakob Stoklund Olesen 984997b3a0 Enable sub-sub-register copy coalescing. ... It is now possible to coalesce weird skewed sub-register copies by picking a super-register class larger than both original registers. The included test case produces code like this: vld2.32 {d16, d17, d18, d19}, [r0]! vst2.32 {d18, d19, d20, d21}, [r0] We still perform interference checking as if it were a normal full copy join, so this is still quite conservative. In particular, the f1 and f2 functions in the included test case still have remaining copies because of false interference. llvm-svn: 156878		2012-05-15 23:31:35 +00:00
