[PATCH 0/4] Graphite code generation for OpenCL.

[Sebastian Pop]

Hi,

I went over the patches submitted by Alexey and Alexander:

  Make some of the graphite functions from graphite-clast-to-gimple.c
    exposed for the new files.
  Conservatively estimate subscript upper bound from the loop iteration
    domain.
  Code generation for OpenCL.

and I made some stylistic changes (reducing the number of warnings of
the script contrib/check_GNU_style.sh).  I also have corrected some
problems occuring when configuring with CLooG.org:

  Make it bootstrap with CLooG.org.

The result is that the graphite branch passed bootstrap with all these
patches on amd64-linux.  I am installing these patches in the graphite
branch.  We will need some testcases that will exercise this new code
generation, and I'll set up one of the testing machines to test every
commit to the graphite branch with the new flags.

Thanks again for your contribution, and merry Christmas!
Sebastian
