Tobias Grosser e4e2f7b16e TempScop: Rename SCEVAffFunc to IRAccess 
The SCEVAffFunc is now only used to express memory accesses. Give it a proper
name and rework the class such that this is obvious.

 2011-11-09 22:35:09 +00:00
Tobias Grosser 499f0a48d8 Further remove now invalid SCEVAffFunc features. 
This also removes the construction of MayAliasSets that became invalid when
removing the use of SCEVAffFunc.

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

Tobias Grosser f317e3ac83 Do not check memory accesses additionally with isValidAffineFunction 
This check was necessary because of the use AffineSCEVIterator in TempScopInfo.
As we removed this use recently it is not necessary any more.

Tobias Grosser 60b54f19e6 Detect Parameters directly on the SCEV. 
Instead of using TempScop to find parameters, we detect them directly
on the SCEV. This allows us to remove the TempScop parameter detection
in a subsequent commit.

This fixes a bug reported by Marcello Maggioni <hayarms@gmail.com>

Tobias Grosser 6be480c4ab ScopInfo: Don't add common parameters during realignment to the context. 
Previously we built a context that contained already all parameter dimensions
from the start. We now build a context without any parameter dimensions and

realignment.

Tobias Grosser 76164677f8 ScopDetection: Use SCEVValidator for memory accesses. 
We currently run the old memory access checker in parallel, as we would
otherwise fail in TempScop because of currently unsupported functions. We will

Tobias Grosser 3fb4992221 ScopDetection: Add new SCEV Validator 
The SCEV Validator is used to check if the bound of a loop can be translated
into a polyhedral constraint. The new validator is more general as the check
used previously and e.g. allows bounds like 'smax 1, %a'. At the moment, we
only allow signed comparisons. Also, the new validator is only used to verify
loop bounds. Memory accesses are still handled by the old validator.

Tobias Grosser 792509b0db Register Polly passes automatically 
Polly adds, after it is loaded into opt or clang, its passes to the default set
of -O3 passes. This means optimizing a program with clang and Polly becomes as
simple as executing.

clang -Xclang -load -Xclang lib/LLVMPolly.so -O3 program.c

The same should work for dragonegg powered gfortran, g++, ... or any other tool
that uses the PassManagerBuilder.

Warning: Even though using Polly became with this commit extremly easy, Polly
         is still Pre-Alpha Quality. This means in most cases it will rather
         destroy the world than doing anything positive. ;-)
