Reject really weird coalescer case when trying to merge identical subregisters of different register classes. e.g. %reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3 Where %reg1048 is a GR32 register. This is not impossible to handle, but it is pretty hard and very rare. This should unbreak the dragonegg builder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102672 91177308-0d34-0410-b5e6-96231b3b80d8
