Jakob Stoklund Olesen 28e104bcb0 Explicitly request physreg coalesing for a bunch of Thumb2 unit tests. ... These tests all follow the same pattern: mov r2, r0 movs r0, #0 $CMP r2, r1 it eq moveq r0, #1 bx lr The first 'mov' can be eliminated by rematerializing 'movs r0, #0' below the test instruction: $CMP r0, r1 mov.w r0, #0 it eq moveq r0, #1 bx lr So far, only physreg coalescing can do that. The register allocators won't yet split live ranges just to eliminate copies. They can learn, but this particular problem is not likely to show up in real code. It only appears because r0 is used for both the function argument and return value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130858 91177308-0d34-0410-b5e6-96231b3b80d8		2011-05-04 19:02:07 +00:00
