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 deals with loops in an oacc kernels region which are
annotated using "#pragma acc loop". It expands such a loop as a normal
loop, which has the effect of ignoring the "#pragma acc loop".



Ping^2.

Thanks,
- Tom
