Hi,
this patch series for stage1 trunk adds support to:
- parallelize oacc kernels regions using parloops, and
- map the loops onto the oacc gang dimension.
The patch series contains these patches:
1 Insert new exit block only when needed in
transform_to_exit_first_loop_alt
2 Make create_parallel_loop return void
3 Ignore reduction clause on kernels directive
4 Implement -foffload-alias
5 Add in_oacc_kernels_region in struct loop
6 Add pass_oacc_kernels
7 Add pass_dominator_oacc_kernels
8 Add pass_ch_oacc_kernels
9 Add pass_parallelize_loops_oacc_kernels
10 Add pass_oacc_kernels pass group in passes.def
11 Update testcases after adding kernels pass group
12 Handle acc loop directive
13 Add c-c++-common/goacc/kernels-*.c
14 Add gfortran.dg/goacc/kernels-*.f95
15 Add libgomp.oacc-c-c++-common/kernels-*.c
16 Add libgomp.oacc-fortran/kernels-*.f95
The first 9 patches are more or less independent, but patches 10-16 are
intended to be committed at the same time.
Bootstrapped and reg-tested on x86_64.
Build and reg-tested with nvidia accelerator, in combination with a
patch that enables accelerator testing (which is submitted at
https://gcc.gnu.org/ml/gcc-patches/2015-10/msg01771.html ).
I'll post the individual patches in reply to this message.
This patch adds Fortran oacc kernels execution tests.
Thanks,
- Tom
