Consider this case: vreg1 = A2_zxth vreg0 (1) ... vreg2 = A2_zxth vreg1 (2) Redundant instruction elimination could delete the instruction (1) because the user (2) only cares about the low 16 bits. Then it could delete (2) because the input is already zero-extended. The problem is that the properties allowing each individual instruction to be deleted depend on the existence of the other instruction, so either one can be deleted, but not both. The existing check for this situation in RIE was insufficient. The fix is to update all dependent cells when an instruction is removed (replaced via COPY) in RIE. llvm-svn: 276792 |
