[IRBuilder][RS4GC] Require FunctionCallee when creating statepoint

2022-02-04T08:47:32+00:00

This makes the statepoint methods in IRBuilder accept a
FunctionCallee, which carries both the callee and function type.
This is used to add the elementtype attribute to the statepoint call.

RS4GC requires an additional tweak to actually preserve that attribute
-- previously the attributes on the call were completely overwritten.

[rs4gc/tests] Remove use of internal debug flags

2021-03-06T17:20:02+00:00

As a pragmatic tradeoff, the ease of updating the tests outweighs the slightly easier to understand test conditions.  Where revevant, debug output was converted to comments to help human understanding.

Revert "Temporarily Revert "Add basic loop fusion pass.""

2019-04-17T04:52:47+00:00

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Temporarily Revert "Add basic loop fusion pass."

2019-04-17T02:12:23+00:00

As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

[PM] port Rewrite Statepoints For GC to the new pass manager.

2017-12-15T09:32:11+00:00

Summary:
The port is nearly straightforward.
The only complication is related to the analyses handling,
since one of the analyses used in this module pass is domtree,
which is a function analysis. That requires asking for the results
of each function and disallows a single interface for run-on-module
pass action.

Decided to copy-paste the main body of this pass.
Most of its code is requesting analyses anyway, so not that much
of a copy-paste.

The rest of the code movement is to transform all the implementation
helper functions like stripNonValidData into non-member statics.

Extended all the related LLVM tests with new-pass-manager use.
No failures.

[RewriteStatepointsForGC] All constant should have null base pointer

2016-05-27T13:13:59+00:00

Currently we consider that each constant has itself as a base value. I.e "base(const) = const". 
This introduces couple of problems when we are trying to avoid reporting constants in statepoint live sets:

1. When querying "base( phi(const1, const2) )" we will get "phi(const1, const2)" as a base pointer. Since 
   it's not a constant we will record it in a stack map. However on practice we don't want this to happen
   (constant are never relocated).
2. base( phi(const, gc ptr) ) = phi( const, base(gc ptr) ). This particular case imposes challenge on our 
   runtime - we don't expect to see constant base pointers other than null. This problems can be avoided 
   by treating all constant as if they were derived from null pointer base. I.e in a first case we will 
   not include constant pointer in a stack map at all. In a second case we will get "phi(null, base(gc ptr))" 
   as a base pointer which is a lot more convenient.

[RS4GC] Clamp UseDeoptBundles to true and update tests

2016-01-29T00:28:57+00:00

The full diff for the test directory may be hard to read because of the
filename clash; so here's all that happened as far as the tests are
concerned:

```
cd test/Transforms/RewriteStatepointsForGC
git rm *ll
git mv deopt-bundles/* ./
rmdir deopt-bundles
find . -name '*.ll' | xargs gsed -i 's/-rs4gc-use-deopt-bundles //g'
```
