------------------------------------------------------------------------ r155817 | void | 2012-04-30 03:44:54 -0700 (Mon, 30 Apr 2012) | 9 lines Second attempt at PR12573: Allow the "SplitCriticalEdge" function to split the edge to a landing pad. If the pass is *sure* that it thinks it knows what it's doing, then it may go ahead and specify that the landing pad can have its critical edge split. The loop unswitch pass is one of these passes. It will split the critical edges of all edges coming from a loop to a landing pad not within the loop. Doing so will retain important loop analysis information, such as loop simplify. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_31@155833 91177308-0d34-0410-b5e6-96231b3b80d8

------------------------------------------------------------------------ r155668 | atrick | 2012-04-26 14:48:25 -0700 (Thu, 26 Apr 2012) | 8 lines Fix the SD scheduler to avoid gluing the same node twice. DAGCombine strangeness may result in multiple loads from the same offset. They both may try to glue themselves to another load. We could insist that the redundant loads glue themselves to each other, but the beter fix is to bail out from bad gluing at the time we detect it.

------------------------------------------------------------------------ r155466 | chandlerc | 2012-04-24 11:42:47 -0700 (Tue, 24 Apr 2012) | 17 lines Fix a crash on valid (if UB) bitcode that is produced for some global constants in C++11 mode. I have no idea why it required such particular circumstances to get here, the code seems clearly to rely upon unchecked assumptions. Specifically, when we decide to form an index into a struct type, we may have gone through (at least one) zero-length array indexing round, which would have left the offset un-adjusted, and thus not necessarily valid for use when indexing the struct type. This is just an canonicalization step, so the correct thing is to refuse to canonicalize nonsensical GEPs of this form. Implemented, and test case added. Fixes PR12642. Pair debugged and coded with Richard Smith. =] I credit him with most of the debugging, and preventing me from writing the wrong code. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_31@155506 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-18This reverts a long string of commits to the Hexagon backend. TheseChandler Carruth
commits have had several major issues pointed out in review, and those issues are not being addressed in a timely fashion. Furthermore, this was all committed leading up to the v3.1 branch, and we don't need piles of code with outstanding issues in the branch. It is possible that not all of these commits were necessary to revert to get us back to a green state, but I'm going to let the Hexagon maintainer sort that out. They can recommit, in order, after addressing the feedback. Reverted commits, with some notes: Primary commit r154616: HexagonPacketizer - There are lots of review comments here. This is the primary reason for reverting. In particular, it introduced large amount of warnings due to a bad construct in tablegen. - Follow-up commits that should be folded back into this when reposting: - r154622: CMake fixes - r154660: Fix numerous build warnings in release builds. - Please don't resubmit this until the three commits above are included, and the issues in review addressed. Primary commit r154695: Pass to replace transfer/copy ... - Reverted to minimize merge conflicts. I'm not aware of specific issues with this patch. Primary commit r154703: New Value Jump. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154703: Remove iostream usage - r154758: Fix CMake builds - r154759: Fix build warnings in release builds - Please incorporate these fixes and and review feedback before resubmitting. Primary commit r154829: Hexagon V5 (floating point) support. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154841: Remove unused variable (fixing build warnings) There are also accompanying Clang commits that will be reverted for consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155047 91177308-0d34-0410-b5e6-96231b3b80d8
