Handle global loop counters in fortran oacc kernels
Unable to have loop counters with a scope limited to the kernels region, and
the fact that function scope inhibits parallelization, at the technical
level,
it seems possible to do DCE and get rid of the dead code that is inhibiting
parallelization (in other words, the code copying the loop iterator value
out
of the region), but probably some effort would be involved.
Another possibility is to add an assign of the final value of the loop
iteration variable after the loop to cut the dependency, though this will
only
work for loops where that value is know at compile time -- which is exactly
what pass_scev_cprop does.

openacc kernels directive -- initial support
Hi,
I'm submitting a patch series with initial support for the oacc kernels
directive.
The patch series uses pass_parallelize_loops to implement parallelization of
loops in the oacc kernels region.
The patch series consists of these 8 patches:
...
1 Expand oacc kernels after pass_build_ealias
2 Add pass_oacc_kernels
3 Add pass_ch_oacc_kernels to pass_oacc_kernels
4 Add pass_tree_loop_{init,done} to pass_oacc_kernels
5 Add pass_loop_im to pass_oacc_kernels
6 Add pass_ccp to pass_oacc_kernels
7 Add pass_parloops_oacc_kernels to pass_oacc_kernels
8 Do simple omp lowering for no address taken var
...
The patch series does not yet apply cleanly to trunk, since it's dependent on
the oacc middle end changes present in the gomp-4_0-branch, already submitted by
Thomas for trunk.
Furthermore, it's dependent on an assert fix submitted for trunk ('Fix
gcc_assert in expand_omp_for_static_chunk' @
https://gcc.gnu.org/ml/gcc-patches/2014-11/msg01149.html ).
The patch series is intended for trunk, but - given the dependency on the oacc
middle end changes - has been bootstrapped for x86_64 on top of gomp-4_0-branch.
I'll post the patch series in reply to this email.
Thanks,
- Tom
[ FTR In order to get clean libgomp and goacc test results in gomp-4_0-branch,
to have a good basis for testing, I used the following patch set:
Don't allow flto-partition=balance for fopenacc
Unsubmitted. This works around a compilation problem for
libgomp/testsuite/libgomp.oacc-c-c++-common/asyncwait-2.c that I ran into on
our internal dev branch. I'll investigate whether I can reproduce with
gomp-4_0-branch asap.
