*	[ARM][LowOverheadLoops] Add LR def safety check	Sam Parker	2019-09-17	1	-5/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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] Add CPSR defs	Sam Parker	2019-07-26	1	-16/+13
\| \| \| \| \| \| \| \| \| \|	Both WhileLoopStart and LoopEnd may get turned into a cmp and br pair, so add an implicit def to these pseudo instructions in case that WLS and LE aren't generated. Differential Revision: https://reviews.llvm.org/D65275 llvm-svn: 367089
*	[ARM][LowOverheadLoops] Correct offset checking	Sam Parker	2019-07-11	1	-0/+199
	This patch addresses a couple of problems: 1) The maximum supported offset of LE is -4094. 2) The offset of WLS also needs to be checked, this uses a maximum positive offset of 4094. The use of BasicBlockUtils has been changed because the block offsets weren't being initialised, but the isBBInRange checks both positive and negative offsets. ARMISelLowering has been tweaked because the test case presented another pattern that we weren't supporting. llvm-svn: 365749
