| * | [ARM][LowOverheadLoops] Add LR def safety check | Sam Parker | 2019-09-17 | 1 | -23/+22 |
| | | | | | | | | | | | | | | | | Converting the *LoopStart pseudo instructions into DLS/WLS results in LR being defined. These instructions were inserted on the assumption that LR would already contain the loop counter because a mov is introduced during ISel as the the consumers in the loop can only use LR. That assumption proved wrong! So perform a safety check, finding an appropriate place to insert the DLS/WLS instructions or revert if this isn't possible.

| * | [Alignment] Use llvm::Align in MachineFunction and TargetLowering - fixes ↵ | Guillaume Chatelet | 2019-09-11 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | mir parsing Summary: This catches malformed mir files which specify alignment as log2 instead of pow2. See https://reviews.llvm.org/D65945 for reference, This is patch is part of a series to introduce an Alignment type. See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2019-July/133851.html See this patch for the introduction of the type: https://reviews.llvm.org/D64790 Reviewers: courbet Subscribers: MatzeB, qcolombet, dschuff, arsenm, sdardis, nemanjai, jvesely, nhaehnle, hiraditya, kbarton, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, PkmX, jocewei, jsji, Petar.Avramovic, asbirlea, s.egerton, pzheng, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D67433 llvm-svn: 371608 | ||||
| * | [ARM][LowOverheadLoops] Revert after read/write | Sam Parker | 2019-08-07 | 1 | -0/+128 |
| Currently we check whether LR is stored/loaded to/from inbetween the loop decrement and loop end pseudo instructions. There's two problems here: - It relies on all load/store instructions being labelled as such in tablegen. - Actually any use of loop decrement is troublesome because the value doesn't exist! So we need to check for any read/write of LR that occurs between the two instructions and revert if we find anything. Differential Revision: https://reviews.llvm.org/D65792 llvm-svn: 368130 | |||||
