llvm-3.2 should also build polly in tools subdirectory

[howarth@…]

The llvm-3.2 release will officially support polly...

​http://llvm.org/docs/ReleaseNotes.html

It would be helpful to add polly support to the existing llvm-3.2 package as it will allow debugging of ​http://llvm.org/bugs/show_bug.cgi?id=14140 by the Apple programmers.

The instructions for building polly under llvm are at ​http://polly.llvm.org/get_started.html and will require an isl and cloog-isl package as well as gmp. As I mentioned before in the gcc48 tickets MacPorts really should provide isl/cloog-isl because ppl/cloog-ppl support is deprecated now in FSF gcc trunk.I would also note that Polly does work in llvm-3.2 under clang by using...

/sw/opt/llvm-3.2/bin/clang -Xclang -load -Xclang /sw/opt/llvm-3.2/lib/LLVMPolly.so -O3 -mllvm -polly himenoBMTxpa.c

Note that a fix for ​http://llvm.org/bugs/show_bug.cgi?id=14135 has been proposed...

​http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-October/054710.html

and should be checked in shortly so that 'make polly-test' will function on darwin.

Polly support will require that the isl and cloog packages be updated to the git head versions of those packages.
I was only able to build the llvm polly support under fink against isl 0.10.0 and cloog 0.17.0 because of a cmake
configuration flaw which is now fixed in polly svn. Fortunately the soversions for both isl and cloog are unchanged
and gcc48 still builds against isl/cloog git head without new regressions in the graphite testsuite.

The 'make polly-test' results look reasonable with only three darwin specific regressions.

It may be essential to provide the Apple programmers with prebuilt llvm-3.2/dragonegg-3.2 packages in order to
allow ​http://llvm.org/bugs/show_bug.cgi?id=14140 to be properly debugged. I fear we may have tickled a linker or dyld
bug with dragonegg.so loading LLVMPolly.so.
