Hi,
now that we have committed -foffload-alias in gomp-4_0-branch (
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg00214.html ), we no longer
need the kernels region to be a part of the original function when doing
alias analysis.
So, we no longer have the need to postpone splitting off the kernels
region into a seperate function until after alias analysis, but we can
do this at the same time as when we expand the parallel region.
The following patch series implements that:
1 Move expansion of kernels region back to first omp-expand
2 Update gate_oacc_kernels to handle oacc function
3 Revert "Add skip_stmt parm to pass_dominator::get_sese ()"
4 Revert "Add pass_dominator::sese_mode_p ()"
5 Handle oacc function in parloops
6 Update goacc kernels C testcases
7 Update goacc kernels Fortran testcases
8 Release_defs in expand_omp_atomic_fetch_op
9 Remove BUILT_IN_GOACC_KERNELS_INTERNAL
[ The patch series is broken up into logical bits, but intended as
single commit. Various things in kernels support will be broken in
intermediate stages. ]
Committed to gomp-4_0-branch.
I'll post the patches in reply to this message.
Thanks,
- Tom

This patch moves expansion of the kernels region back to the first
omp-expand pass, before ssa.
There's no longer a need for the region-replacing call to expand into
BUILT_IN_GOACC_KERNELS_INTERNAL and subsequently map onto
BUILT_IN_GOACC_PARALLEL during the second omp-expand pass. The
BUILT_IN_GOACC_KERNELS_INTERNAL call was modeled transparant to alias
analysis, and that's no longer needed.
Thanks,
- Tom

This patch updates the kernels pass group gate function.
Before, it needed to trigger on functions containing kernel regions.
Now, it needs to trigger on oacc functions that used to be kernels
regions before they were split off.
Furthermore, I've duplicated the parloops gate here
(flag_tree_parallelize_loops > 1). There's not much sense in running
the pass group unless we're trying to parallelize.
Consequently, I needed to add a "-ftree-parallelize-loops=32" settting
to a testcase which missed that setting.
Thanks,
- Tom

We were using the skip_stmt functionality in pass_dominator to skip over
a statement '.omp_data_i = &.omp_data_arr' in the kernels region. That
statement is removed during function split-off, so we no longer
encounter that statement in the kernels pass group.
This patch reverts the stip_stmt functionality.

We needed the sese_mode_p functionality in the dominators pass to limit
optimization scope to kernels regions. Now we no longer encounter
kernels region in the kernels pass group, but split-off function that
used to be kernels region. So we no longer need this functionality.
This patch reverts the sese_mode_p functionality.
Thanks,
- Tom

This patch removes handling of kernels regions in tree-parloops.c, and
adds handling of oacc functions that used to be kernels regions before
they were split off.
That means we no longer add a parallel pragma. OTOH, we now have to
clear PROP_gimple_eomp in order to trigger the subsequent omp-expand pass.
Thanks,
- Tom

Handle oacc function in parloops
2015-11-04 Tom de Vries <tom@codesourcery.com>
* omp-low.c (set_oacc_fn_attrib): Remove static.
* omp-low.h (set_oacc_fn_attrib): Declare.
* tree-parloops.c (create_parallel_loop): Remove region_entry parameter.
Remove handling of oacc kernels pragma and GOACC_kernels_internal call.
Remove insertion of oacc parallel pragma. Set oacc function attributes.
(gen_parallel_loop): Remove region_entry parameter.
(get_omp_data_i_param): New function.
(try_create_reduction_list): Use get_omp_data_i_param instead of
gimple_stmt_omp_data_i_init_p.
(ref_conflicts_with_region): Handle GIMPLE_RETURN.
(oacc_entry_exit_ok_1): Same. Add missing is_gimple_call test before
gimple_call_internal_p test.
(oacc_entry_exit_ok): Remove region_entry parameter. Use
get_omp_data_i_param instead of get_omp_data_i. Set region_bbs to all
bbs in function. Use function entry as region entry.
(parallelize_loops): Allow oacc functions and parallelized function if
oacc_kernels_p. Remove region_entry variable.
(pass_parallelize_loops_oacc_kernels::execute): Clear PROP_gimple_eomp
if a loop was parallelized.

The parloops pass constructs an atomic update:
...
#pragma omp atomic_load
D.1839_59 = *&.paral_data_load.33_51->reduction.23;
D.1840_60 = sum.27_56 + D.1839_59;
#pragma omp atomic_store (D.1840_60);
...
The expand_omp_atomic_fetch_op function removes the update statement but
doesn't release the ssa-name D.1840_60 defined by the update statement.
This causes an error when running ccp in lto1. We run into trouble here
for this unreleased ssa-name, because SSA_NAME_VAR (var) == NULL_TREE
and TREE_CODE (NULL_TREE) causes a sigsegv:
...
get_default_value (tree var)
{
ccp_prop_value_t val = { UNINITIALIZED, NULL_TREE, 0 };
gimple *stmt;
stmt = SSA_NAME_DEF_STMT (var);
if (gimple_nop_p (stmt))
{
/* Variables defined by an empty statement are those used
before being initialized. If VAR is a local variable, we
can assume initially that it is UNDEFINED, otherwise we must
consider it VARYING. */
if (!virtual_operand_p (var)
&& TREE_CODE (SSA_NAME_VAR (var)) == VAR_DECL)
val.lattice_val = UNDEFINED;
...
This patch fixes the problem by releasing the ssa-name in
expand_omp_atomic_fetch_op function.
Thanks,
- Tom
