f7302c8b - [PlaceSafepoints] Clamp NoStatepoints to true

Thu, 28 Jan 2016 21:51:14 +0000

[PlaceSafepoints] Clamp NoStatepoints to trueThis change permanently clamps -spp-no-statepoints to true (the codedeletion will come later). Tests that specifically testedPlaceSafepoint's ability to wrap calls in gc.statepoint have been movedto RS4GC's test suite.llvm-svn: 259096 List of files: /llvm-project-15.0.7/llvm/test/Transforms/PlaceSafepoints/split-backedge.ll

a1d39ba9 - [Statepoints] Support for "patchable" statepoints.

Tue, 12 May 2015 23:52:24 +0000

[Statepoints] Support for "patchable" statepoints.Summary:This change adds two new parameters to the statepoint intrinsic, `i64 id`and `i32 num_patch_bytes`. `id` gets propagated to the ID fieldin the generated StackMap section. If the `num_patch_bytes` isnon-zero then the statepoint is lowered to `num_patch_bytes` bytes ofnops instead of a call (the spill and reload code remains unchanged).A non-zero `num_patch_bytes` is useful in situations where a languageruntime requires complete control over how a call is lowered.This change brings statepoints one step closer to patchpoints. Withsome additional work (that is not part of this patch) it should bepossible to get rid of `TargetOpcode::STATEPOINT` altogether.PlaceSafepoints generates `statepoint` wrappers with `id` set to`0xABCDEF00` (the old default value for the ID reported in the stackmap)and `num_patch_bytes` set to `0`. This can be made more sophisticatedlater.Reviewers: reames, pgavlin, swaroop.sridhar, AndyAyersSubscribers: llvm-commitsDifferential Revision: http://reviews.llvm.org/D9546llvm-svn: 237214 List of files: /llvm-project-15.0.7/llvm/test/Transforms/PlaceSafepoints/split-backedge.ll

5708cca7 - [PlaceSafepoints] Remove dependence on LoopSimplify

Tue, 12 May 2015 20:43:48 +0000

[PlaceSafepoints] Remove dependence on LoopSimplifyAs a step towards getting rid of internal pass manager hack entirely, remove the need for loop simplify to run in the inner pass manager. The new code does produce slightly different loop structures, so this isn't technically NFC.Differential Revision: http://reviews.llvm.org/D9585llvm-svn: 237172 List of files: /llvm-project-15.0.7/llvm/test/Transforms/PlaceSafepoints/split-backedge.ll

0b1b3874 - [PlaceSafepoints] Adjust enablement logic to default to off and be GC configurable per GC

Sat, 21 Feb 2015 00:09:09 +0000

[PlaceSafepoints] Adjust enablement logic to default to off and be GC configurable per GCPreviously, this pass ran over every function in the Module if added to the pass order. With this change, it runs only over those with a GC attribute where the GC explicitly opts in. A GC can also choose which of entry safepoint polls, backedge safepoint polls, and call safepoints it wants. I hope to get these exposed as checks on the GCStrategy at some point, but for now, the checks are manual string comparisons.llvm-svn: 230097 List of files: /llvm-project-15.0.7/llvm/test/Transforms/PlaceSafepoints/split-backedge.ll

0edbf2e4 - Introduce more tests for PlaceSafepoints
