LDtocL, and other loads that roughly correspond to the TOC_ENTRY SDAG node, represent loads from the TOC, which is invariant. As a result, these loads can be hoisted out of loops, etc. In order to do this, we need to generate GOT-style MMOs for TOC_ENTRY, which requires treating it as a legitimate memory intrinsic node type. Once this is done, the MMO transfer is automatically handled for TableGen-driven instruction selection, and for nodes generated directly in PPCISelDAGToDAG, we need to transfer the MMOs manually. Also, we were not transferring MMOs associated with pre-increment loads, so do that too. Lastly, this fixes an exposed bug where R30 was not added as a defined operand of UpdateGBR. This problem was highlighted by an example (used to generate the test case) posted to llvmdev by Francois Pichet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230553 91177308-0d34-0410-b5e6-96231b3b80d8 |
