Jakob Stoklund Olesen d40d4c34f7 Resolve conflicts involving dead vector lanes for -new-coalescer. ... A common coalescing conflict in vector code is lane insertion: %dst = FOO %src = BAR %dst:ssub0 = COPY %src The live range of %src interferes with the ssub0 lane of %dst, but that lane is never read after %src would have clobbered it. That makes it safe to merge the live ranges and eliminate the COPY: %dst = FOO %dst:ssub0 = BAR This patch teaches the new coalescer to resolve conflicts where dead vector lanes would be clobbered, at least as long as the clobbered vector lanes don't escape the basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164250 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-19 21:29:18 +00:00
