This replaces the old option -polly-use-pocc. Also call the passes uniformly
-polly-opt-pocc and -polly-opt-isl.

llvm-svn: 145071

We disable Polly by default and add a new option '-polly' that enables Polly.
This allows us to create an the alias

$ alias clang clang -Xclang -load -Xclang LLVMPolly.so

which loads Polly always into clang. It can now be enabled by running:

$ clang -O3 -mllvm -polly file.c

To enable it by default an alias pollycc can be create

$ alias pollycc clang -O3 -mllvm -polly

Instead we switch to the recommended getName(). This fixes compilation with
recent versions of LLVM.

Fix suggested by Sebastian Pop.

llvm-svn: 144900

- Use uppercase letters according to the LLVM coding style
- Rename functions to not include 'tiledSchedule', but just Schedule. This
  is more correct as tiling might be disabled.

Style fix, noted by Sebastian Pop.

The new isl_id support for parmeters created problems when importing new
access functions. Even though the parameters had the same names,
they were mapped to different ids and where therefore incompatible.
We copy the ids now from the old parameter dimensions. This fixes the
problem.

llvm-svn: 144642

Parameters can be complex SCEV expressions, but they can also be single scalar
values. If a parameters is such a simple scalar value and the value is named,
use this name to name the isl parameter dimensions.

This does not work reliable and is probably not needed. I accidentally changed
this in this recent commit:

    ScopDetect: Use INVALID macro to fail in case of aliasing

    This simplifies the code and also makes the error message available to the
    graphviz scop viewer.

address is part of the access function. Also remove unused special cases that
were necessery when the base address was still contained in the access function

llvm-svn: 144280

llvm-svn: 144279

Previously we allowed in access functions only a single SCEVUnknown, which later
became the base address. We now use getPointerBase() to derive the base address
and all remaining unknowns are handled as parameters. This allows us to handle
cases like A[b+c];

The SCEVAffFunc is now only used to express memory accesses. Give it a proper
name and rework the class such that this is obvious.

llvm-svn: 144231

This also removes the construction of MayAliasSets that became invalid when
removing the use of SCEVAffFunc.

llvm-svn: 144230

We do not use it anymore. It was replaced by SCEVVisitors like the
SCEVValidator.

llvm-svn: 144229

This check was necessary because of the use AffineSCEVIterator in TempScopInfo.
As we removed this use recently it is not necessary any more.
