Hi!
I'd like to merge (most of) gomp-4_0-branch to trunk.
Except for unknown bugs and known outstanding unclear spots in
the standard, the branch right now implements OpenMP 4.0 standard
with the following caveats that I hope can be dealt with incrementally
later on:
1) Fortran front-end support of OpenMP 4.0 isn't written, so Fortran
will for now only support OpenMP 3.1 and earlier, except for
library only features.
2) offloading isn't implemented, for the merge I've actually took out
the splay tree and plugin support from target.c, because it was so
far only useful for hack testing, there aren't any plugins yet
and when there will be, target.c will need to be modified.
#pragma omp target{, data, update} is supported, but will always
for now fall back to host execution.
3) #pragma omp declare simd is right now parsed and diagnosed, but
we don't actually generate the elemental function entry points
(ABI issue for public function, but we have yet to decide on the
ABI) and vectorizer doesn't use them (only optimization issue).
4) C++ tasks with firstprivate variables that need copy constructors
can't be discarded right now during cancellation, because there is
no way yet to call corresponding destructors. They will be therefore
started and if they hit some early cancellation point, they will be
cancelled there, otherwise they will simply run all the way through.
Shouldn't be that hard to handle this, but IMHO can be done
incrementally.
I've bootstrapped/regtested the merge on x86_64-linux and i686-linux.
I think most of the patch if not all of it falls under my OpenMP
maintainership and the vectorization part of the OpenMP 4.0 support
has been merged earlier, still I'd appreciate acks from the front-end
maintainers because the patch is very large and affects the frontends
quite a lot. And of course, if anybody has further comments, they'll
be appreciated.
Because the patch is too large for gcc-patches limits (1.15MB), I've
split it into 6 parts:
[1/6] gcc/ support other than gcc/{c/,cp/,testsuite/}
[2/6] C FE changes
[3/6] C++ FE changes
[4/6] gcc/testsuite
[5/6] libgomp/ (other than libgomp/testsuite/)
[6/6] libgomp/testsuite/
