* Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg ofEvan Cheng2009-09-284-5/+41
| | | | | | | | | | | | physical registers. This is especially critical for the later two since they start the live interval of a super-register. e.g. %DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1 If this instruction is eliminated, the register scavenger will not be happy as D0 is not defined previously. This fixes PR5055. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82968 91177308-0d34-0410-b5e6-96231b3b80d8
