Store the llvm::Value pointers of the AliasSet instead of the AliasSet
itself.
We have to be careful about changed IR when the message is generated,
because the Value pointers might not exist anymore. This would render
the Diagnostic invalid. For now we just assert there.
Simply do not retreive a diagnostic message after the IR has changed
it's not valid information anyway.

Remove the PoCC and ScopLib support from Polly as we do not have a
user/maintainer for it.
Differential Revision: http://reviews.llvm.org/D4871
llvm-svn: 215563
Use the explicit analysis if possible, only for splitBlock we will continue
to use the Pass * argument. This change allows us to remove the getAnalysis
calls from the code generation.

There is no needed for neither 1-dimensional nor higher dimensional arrays to
require positive offsets in the outermost array dimension.
We originally introduced this assumption with the support for delinearizing
multi-dimensional arrays.

+ Remove the class IslGenerator which duplicates the functionality of
IslExprBuilder.
+ Use the IslExprBuilder to create code for memory access relations.
+ Also handle array types during access creation.
+ Enable scev codegen for one of the transformed memory access tests,
thus access creation without canonical induction variables available.
+ Update one test case to the new output.
llvm-svn: 214659
The updated tests use a different context than the old ones did.
Other than that only their path and the code generation we use
changed.
llvm-svn: 214657
+ Split all reduction dependences and map them to the causing memory accesses.
+ Print the types & base addresses of broken reductions for each "reduction
parallel" marked loop (OpenMP style).
+ 3 test cases to show how reductions are now represented in the isl ast.
The mapping "(ast) loops -> broken reductions" is also needed to find the
memory accesses we need to privatize in a loop.
llvm-svn: 214489
The functions isParallel, isInnermostParallel and IsOutermostParallel in
IslAstInfo will now return true even in the presence of broken reductions.
To compensate for this change the negated result of isReductionParallel can
be used.
llvm-svn: 214488
+ Perform the parallelism check on the innermost loop only once.
+ Inline the markOpenmpParallel function.
+ Rename all IslAstUserPayload * into Payload to make it consistent.

Whe we build the IslAst we visit for nodes (in pre and post order) as well as
user/domain nodes. As these two sets are non overlapping we do not need to
check if we annotated a node earlier when we visit it.
llvm-svn: 214170
Use the fact that if we visit a for node first in pre and next in post order
we know we did not visit any children, thus we found an innermost loop.
+ Test case for an innermost loop with a conditional inside
llvm-svn: 213870
+ Renamed context into build when it's the isl_ast_build
+ Use the IslAstInfo functions to extract the schedule of a node
+ Use the IslAstInfo functions to extract the build/context of a node
+ Move the payload struct into the IslAstInfo class
+ Use a constructor and destructor (also new and delete) to
allocate/initialize the payload struct
llvm-svn: 213792
Offer the static functions to extract information out of an IslAst for node
as members of IslAstInfo not as top level entities.
+ Refactor common code
+ Add isParallel and isReductionParallel
+ Rename IslAstUser to IslAstUserPayload to make it clear this is just a (or
the) payload struct.
