Andrea Di Biagio 2fddd75212 Fix for PR23103. Correctly propagate the 'IsUndef' flag to the register operands of a commuted instruction. ... Revision 220239 exposed a latent bug in method 'TargetInstrInfo::commuteInstruction'. When commuting the operands of a machine instruction, method 'commuteInstruction' didn't correctly propagate the 'IsUndef' flag to the register operands of the new (commuted) instruction. Before this patch, the following instruction: %vreg4<def> = VADDSDrr %vreg14, %vreg5<undef>; FR64:%vreg4,%vreg14,%vreg5 was wrongly converted by method 'commuteInstruction' into: %vreg4<def> = VADDSDrr %vreg5, %vreg14<undef>; FR64:%vreg4,%vreg5,%vreg14 The correct instruction should have been: %vreg4<def> = VADDSDrr %vreg5<undef>, %vreg14; FR64:%vreg4,%vreg5,%vreg14 This patch fixes the problem in method 'TargetInstrInfo::commuteInstruction'. When swapping the operands of a machine instruction, we now make sure that 'IsUndef' flags are correctly set. Added test case 'pr23103.ll'.
