This patch trivially adds braces and reindents the
OMP_CLAUSE_TO/OMP_CLAUSE_FROM/OMP_CLAUSE__CACHE_ stanza in
c_finish_omp_clause and finish_omp_clause, in preparation for the
following patch (to clarify the diff a little).
2022-09-13 Julian Brown <julian@codesourcery.com>
gcc/c/
* c-typeck.cc (c_finish_omp_clauses): Add braces and reindent
OMP_CLAUSE_TO/OMP_CLAUSE_FROM/OMP_CLAUSE__CACHE_ stanza.
gcc/cp/
* semantics.cc (finish_omp_clause): Add braces and reindent
OMP_CLAUSE_TO/OMP_CLAUSE_FROM/OMP_CLAUSE__CACHE_ stanza.

(This one has already been approved. Some adjustments have been made to
this version for other patches already committed.)
This patch is an extension and rewrite/rethink of the following two patches:
"OpenMP/OpenACC: Add inspector class to unify mapped address analysis"
https://gcc.gnu.org/pipermail/gcc-patches/2022-March/591977.html
"OpenMP: Handle reference-typed struct members"
https://gcc.gnu.org/pipermail/gcc-patches/2022-March/591978.html
The latter was reviewed here by Jakub:
https://gcc.gnu.org/pipermail/gcc-patches/2022-May/595510.html with the
with the comment,
> Why isn't a reference to pointer handled that way too?
and that opened a whole can of worms... generally, C++ references were
not handled very consistently after the clause-processing code had been
extended several times already for both OpenACC and OpenMP, and many
cases of using C++ (and Fortran) references were broken. Even some
cases not involving references were being mapped incorrectly.
At present a single clause may be turned into several mapping nodes,
or have its mapping type changed, in several places scattered through
the front- and middle-end. The analysis relating to which particular
transformations are needed for some given expression has become quite hard
to follow. Briefly, we manipulate clause types in the following places:
1. During parsing, in c_omp_adjust_map_clauses. Depending on a set of
rules, we may change a FIRSTPRIVATE_POINTER (etc.) mapping into
ATTACH_DETACH, or mark the decl addressable.
2. In semantics.cc or c-typeck.cc, clauses are expanded in
handle_omp_array_sections (called via {c_}finish_omp_clauses, or in
finish_omp_clauses itself. The two cases are for processing array
sections (the former), or non-array sections (the latter).
3. In gimplify.cc, we build sibling lists for struct accesses, which
groups and sorts accesses along with their struct base, creating
new ALLOC/RELEASE nodes for pointers.
4. In gimplify.cc:gimplify_adjust_omp_clauses, mapping nodes may be
adjusted or created.
This patch doesn't completely disrupt this scheme, though clause
types are no longer adjusted in c_omp_adjust_map_clauses (step 1).
Clause expansion in step 2 (for C and C++) now uses a single, unified
mechanism, parts of which are also reused for analysis in step 3.
Rather than the kind-of "ad-hoc" pattern matching on addresses used to
expand clauses used at present, a new method for analysing addresses is
introduced. This does a recursive-descent tree walk on expression nodes,
and emits a vector of tokens describing each "part" of the address.
This tokenized address can then be translated directly into mapping nodes,
with the assurance that no part of the expression has been inadvertently
skipped or misinterpreted. In this way, all the variations of ways
pointers, arrays, references and component accesses can be teased apart
into easily-understood cases - and we know we've "parsed" the whole
address before we start analysis, so the right code paths can easily
be selected.
For example, a simple access "arr[idx]" might parse as:
base-decl access-indexed-array
or "mystruct->foo[x]" with a pointer "foo" component might parse as:
base-decl access-pointer component-selector access-pointer
A key observation is that support for "array" bases, e.g. accesses
whose root nodes are not structures, but describe scalars or arrays,
and also *one-level deep* structure accesses, have first-class support
in gimplify and beyond. Expressions that use deeper struct accesses
or e.g. multiple indirections were more problematic: some cases worked,
but lots of cases didn't. This patch reimplements the support for those
in gimplify.cc, again using the new "address tokenization" support.
An expression like "mystruct->foo->bar[0:10]" used in a mapping node will
translate the right-hand access directly in the front-end. The base for
the access will be "mystruct->foo". This is handled recursively -- there
may be several accesses of "mystruct"'s members on the same directive,
so the sibling-list building machinery can be used again. (This was
already being done for OpenACC, but the new implementation differs
somewhat in details, and is more robust.)
For OpenMP, in the case where the base pointer itself,
i.e. "mystruct->foo" here, is NOT mapped on the same directive, we
create a "fragile" mapping. This turns the "foo" component access
into a zero-length allocation (which is a new feature for the runtime,
so support has been added there too).
A couple of changes have been made to how mapping clauses are turned
into mapping nodes:
The first change is based on the observation that it is probably never
correct to use GOMP_MAP_ALWAYS_POINTER for component accesses (e.g. for
references), because if the containing struct is already mapped on the
target then the host version of the pointer in question will be corrupted
if the struct is copied back from the target. This patch removes all
such uses, across each of C, C++ and Fortran.
The second change is to the way that GOMP_MAP_ATTACH_DETACH nodes
are processed during sibling-list creation. For OpenMP, for pointer
components, we must map the base pointer separately from an array section
that uses the base pointer, so e.g. we must have both "map(mystruct.base)"
and "map(mystruct.base[0:10])" mappings. These create nodes such as:
GOMP_MAP_TOFROM mystruct.base
G_M_TOFROM *mystruct.base [len: 10*elemsize] G_M_ATTACH_DETACH mystruct.base
Instead of using the first of these directly when building the struct
sibling list then skipping the group using GOMP_MAP_ATTACH_DETACH,
leading to:
GOMP_MAP_STRUCT mystruct [len: 1] GOMP_MAP_TOFROM mystruct.base
we now introduce a new "mini-pass", omp_resolve_clause_dependencies, that
drops the GOMP_MAP_TOFROM for the base pointer, marks the second group
as having had a base-pointer mapping, then omp_build_struct_sibling_lists
can create:
GOMP_MAP_STRUCT mystruct [len: 1] GOMP_MAP_ALLOC mystruct.base [len: ptrsize]
This ends up working better in many cases, particularly those involving
references. (The "alloc" space is immediately overwritten by a pointer
attachment, so this is mildly more efficient than a redundant TO mapping
at runtime also.)
There is support in the address tokenizer for "arbitrary" base expressions
which aren't rooted at a decl, but that is not used as present because
such addresses are disallowed at parse time.
In the front-ends, the address tokenization machinery is mostly only
used for clause expansion and not for diagnostics at present. It could
be used for those too, which would allow more of my previous "address
inspector" implementation to be removed.
The new bits in gimplify.cc work with OpenACC also.
