Richard,
My understanding is the Sebastian intended to at least switch graphite from
legacy
cloog-ppl to cloog.org (cloog-isl) for gcc 4.6. This has the advantage of
decoupling
cloog from ppl and thus elimimating the problem of the ppl 0.11 ABI change.
I've confirmed
on darwin that if gcc's graphite is built under the older 0.10.4 ABI and cloog
is built
against the newer ppl 0.11 ABI that there is graphite testsuite breakage. Using
cloog.org eliminates
this issue entirely since the cloog-isl is in use (eliminating the need to
synchronize
which ppl is in use for graphite and cloog).
