Somewhat motivating case In PR43146: https://bugs.llvm.org/show_bug.cgi?id=43146 But that's a lot more complicated. llvm-svn: 370381
Add a GISelPredicateCode to the stxr_* PatFrags in AArch64InstrAtomics.td. This allows us to select these intrinsics. Differential Revision: https://reviews.llvm.org/D65779 llvm-svn: 370382
…date tests. Summary: I'm not planning to check this in at the moment, but feedback is very welcome, in particular how this affects performance. The feedback obtains here will guide the next steps towards enabling this. This patch enables the use of MemorySSA in the loop pass manager. Passes that currently use MemorySSA: - EarlyCSE Passes that use MemorySSA after this patch: - EarlyCSE - LICM - SimpleLoopUnswitch Loop passes that update MemorySSA (and do not use it yet, but could use it after this patch): - LoopInstSimplify - LoopSimplifyCFG - LoopUnswitch - LoopRotate - LoopSimplify - LCSSA Loop passes that do *not* update MemorySSA: - IndVarSimplify - LoopDelete - LoopIdiom - LoopSink - LoopUnroll - LoopInterchange - LoopUnrollAndJam - LoopVectorize - LoopReroll - IRCE Reviewers: chandlerc, george.burgess.iv, davide, sanjoy, gberry Subscribers: jlebar, Prazek, dmgreen, jdoerfert, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D58311 llvm-svn: 370384
Sometimes it's easier to resolve merge conflict than arguing. llvm-svn: 370385
This removes the curses result formatter which appears to be broken. Passing --curses to dotest.py screws up my terminal and doesn't run any tests. It even crashes Python on occasion. Differential revision: https://reviews.llvm.org/D66917 llvm-svn: 370386
It used to be possible to enable logging through environment variables read by dotest. This approach is deprecated, as stated in the dotest help output. Instead --channel should be used. Differential revision: https://reviews.llvm.org/D66920 llvm-svn: 370387
AMDGPU uses this for some addressing mode selection patterns. The analysis run itself doesn't do anything so it seems easier to just always require this than adding a way to opt in. llvm-svn: 370388
I dropped the DemandedElts since it seems to be missing from some of the new interfaces, but not others. llvm-svn: 370389
