2020-07-04[Utils] Make -assume-builder/-assume-simplify actually work on Old-PMRoman Lebedev1-0/+1
clang w/ old-pm currently would simply crash when -mllvm -enable-knowledge-retention=true is specified. Clearly, these two passes had no Old-PM test coverage, which would have shown the problem - not requiring AssumptionCacheTracker, but then trying to always get it. Also, why try to get domtree only if it's cached, but at the same time marking it as required?

2020-05-23Added a new IRCanonicalizer pass.Michal Paszkowski1-0/+1
Summary: Added a new IRCanonicalizer pass which aims to transform LLVM modules into a canonical form by reordering and renaming instructions while preserving the same semantics. The canonicalizer makes it easier to spot semantic differences when diffing two modules which have undergone different passes.

2020-05-21Add CanonicalizeFreezeInLoops passJuneyoung Lee1-0/+1
Summary: If an induction variable is frozen and used, SCEV yields imprecise result because it doesn't say anything about frozen variables. Due to this reason, performance degradation happened after https://reviews.llvm.org/D76483 is merged, causing SCEV yield imprecise result and preventing LSR to optimize a loop. The suggested solution here is to add a pass which canonicalizes frozen variables inside a loop. To be specific, it pushes freezes out of the loop by freezing the initial value and step values instead & dropping nsw/nuw flags from instructions used by freeze. This solution was also mentioned at https://reviews.llvm.org/D70623 .

2020-04-15Introduce fix-irreducible passSameer Sahasrabuddhe1-0/+1
An irreducible SCC is one which has multiple "header" blocks, i.e., blocks with control-flow edges incident from outside the SCC. This pass converts an irreducible SCC into a natural loop by introducing a single new header block and redirecting all the edges on the original headers to this new block. This is a useful workaround for a limitation in the structurizer which, which produces incorrect control flow in the presence of irreducible regions. The AMDGPU backend provides an option to enable this pass before the structurizer, which may eventually be enabled by default.

2020-03-30Introduce unify-loop-exits pass.Sameer Sahasrabuddhe1-0/+1
For each natural loop with multiple exit blocks, this pass creates a new block N such that all exiting blocks now branch to N, and then control flow is redistributed to all the original exit blocks. The bulk of the tranformation is a new function introduced in BasicBlockUtils that an redirect control flow from a set of incoming blocks to a set of outgoing blocks via a common "hub". This is a useful workaround for a limitation in the structurizer which incorrectly orders blocks when processing a nest of loops. This pass bypasses that issue by ensuring that each natural loop is recognized as a separate region. Since the structurizer is a region pass, it no longer sees a nest of loops in a single region, and instead processes each "level" in the nesting as a separate region. The AMDGPU backend provides a new option to enable this pass before the structurizer, which may eventually be enabled by default.

to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

At -O0, globalopt is not run during the compile step, and we can have a chain of an alias having an immediate aliasee of another alias. The summaries are constructed assuming aliases in a canonical form (flattened chains), and as a result only the base object but no intermediate aliases were preserved. Fix by adding a pass that canonicalize aliases, which ensures each alias is a direct alias of the base object.
