* [Power9] Exploit vector integer extend instructions when indices aren't correct.Tony Jiang2017-07-055-54/+441
| | | | | | | | | | | | | | | This patch adds on to the exploitation added by https://reviews.llvm.org/D33510. This now catches build vector nodes where the inputs are coming from sign extended vector extract elements where the indices used by the vector extract are not correct. We can still use the new hardware instructions by adding a shuffle to move the elements to the correct indices. I introduced a new PPCISD node here because adding a vector_shuffle and changing the elements of the vector_extracts was getting undone by another DAG combine.

Only one will end up using it. * Use MIs.resize(1) instead of MIs.clear();MIs.push_back(I) and prevent GIM_RecordInsn from changing MIs[0].

* [GlobalISel] Refactor Legalizer helpers for libcallsDiana Picus2017-07-053-24/+33
| | | | | | | | | | We used to have a helper that replaced an instruction with a libcall. That turns out to be too aggressive, since sometimes we need to replace the instruction with at least two libcalls. Therefore, change our existing helper to only create the libcall and leave the instruction removal as a separate step. Also rename the helper accordingly. llvm-svn: 307149

* [SafepointIRVerifier] Add verifier pass for finding GC relocation bugsAnna Thomas2017-07-059-0/+638
| | | | | | | | | | | | | | | | | | | | Original Patch and summary by Philip Reames. RewriteStatepointsForGC tries to rewrite a function in a manner where the optimizer can't end up using a pointer value after it might have been relocated by a safepoint. This pass checks the invariant that RSForGC is supposed to establish and that (if we constructed semantics correctly) later passes must preserve. This has been a really useful diagnostic tool when initially developing the rewriting scheme and has found numerous bugs.

* [FastISel][SelectionDAG]Teach fastISel about GC intrinsicsAnna Thomas2017-07-042-1/+60
| | | | | | | | | | | | | | | | | | | | | | | Summary: We are crashing in LLC at O0 when gc intrinsics are present in the block. The reason being FastISel performs basic block ISel by modifying GC.relocates to be the first instruction in the block. This can cause us to visit the GC relocate before it's corresponding GC.statepoint is visited, which is incorrect. When we lower the statepoint, we record the base and derived pointers, along with the gc.relocates. After this we can visit the gc.relocate. This patch avoids fastISel from incorrectly creating the block with gc.relocate as the first instruction.
