Reassociation's NegateValue moved instructions to the beginning of blocks (after PHIs) without checking for exception handling pads. It's possible for reassociation to move something into an exception handling block so we need to make sure we don't move things too early in the block. This change advances the insertion point past any exception handling pads. If the block we want to move into contains a catchswitch, we cannot move into it. In that case just create a new neg as if we had not found an existing neg to move. Differential Revision: https://reviews.llvm.org/D61089 llvm-svn: 360262 |
