Evan Cheng ddc8678b00 Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of ... 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. llvm-svn: 82968		2009-09-28 05:28:43 +00:00
