2022-01-10c++: Ensure some more that immediate functions aren't gimplified [PR103912]Jakub Jelinek1-0/+11
Immediate functions should never be emitted into assembly, the FE doesn't genericize them and does various things to ensure they aren't gimplified. But the following testcase ICEs anyway due to that, because the consteval function returns a lambda, and operator() of the lambda has decl_function_context of the consteval function. cgraphunit.c then does: /* Preserve a functions function context node. It will later be needed to output debug info. */ if (tree fn = decl_function_context (decl)) { cgraph_node *origin_node = cgraph_node::get_create (fn); enqueue_node (origin_node); } which enqueues the immediate function and then tries to gimplify it, which results in ICE because it hasn't been genericized. When I try similar testcase with constexpr instead of consteval and static constinit auto instead of auto in main, what happens is that the functions are gimplified, later ipa.c discovers they aren't reachable and sets body_removed to true for them (and clears other flags) and we end up with a debug info which has the foo and bar functions without DW_AT_low_pc and other code specific attributes, just stuff from its BLOCK structure and in there the lambda with DW_AT_low_pc etc. The following patch attempts to emulate that behavior early, so that cgraph doesn't try to gimplify those and pretends they were already gimplified and found unused and optimized away. 2022-01-10 Jakub Jelinek <jakub@redhat.com> PR c++/103912 * semantics.c (expand_or_defer_fn): For immediate functions, set node->body_removed to true and clear analyzed, definition and force_output. * decl2.c (c_parse_final_cleanups): Ignore immediate functions for expand_or_defer_fn. * g++.dg/cpp2a/consteval26.C: New test.

2021-12-20c++: ahead-of-time overload set pruning for non-dep callsPatrick Palka1-0/+15
This patch makes us remember the function selected by overload resolution during ahead of time processing of a non-dependent call expression, so that at instantiation time we avoid repeating some of the work of overload resolution for the call. Note that we already do this for non-dependent operator expressions via build_min_non_dep_op_overload. Some caveats: * When processing ahead of time a non-dependent call to a member function template of a currently open class template (as in g++.dg/template/deduce4.C), we end up generating an "inside-out" partial instantiation such as S<T>::foo<int, int>(), the likes of which we're apparently not prepared to fully instantiate. So in this situation, we instead prune to the selected template instead of the specialization in this situation. * This change triggered a latent FUNCTION_DECL pretty printing issue in cpp0x/error2.C -- since we now resolve the call to foo<0> ahead of time, the error now looks like: error: expansion pattern ‘foo()()=0’ contains no parameter pack where the FUNCTION_DECL for foo<0> is clearly misprinted. But this pretty-printing issue could be reproduced without this patch if we define foo as a non-template function. Since this testcase was added to verify pretty printing of TEMPLATE_ID_EXPR, I work around this test failure by making the call to foo type-dependent and thus immune to this ahead of time pruning. * We now reject parts of cpp0x/fntmp-equiv1.C because we notice that the non-dependent call d(f, b) in int d(int, int); template <unsigned long f, unsigned b, typename> e<d(f, b)> d(); is non-constexpr. Since this testcase is about equivalency of dependent names in the context of declaration matching, it seems the best fix here is to make the calls to d, d2 and d3 within the function signatures dependent. gcc/cp/ChangeLog: * call.c (build_new_method_call): For a non-dependent call expression inside a template, returning a templated tree whose overload set contains just the selected function. * semantics.c (finish_call_expr): Likewise. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/error2.C: Make the call to foo type-dependent in order to avoid latent pretty-printing issue for FUNCTION_DECL inside MODOP_EXPR. * g++.dg/cpp0x/fntmp-equiv1.C: Make the calls to d, d2 and d3 within the function signatures dependent. * g++.dg/template/non-dependent16.C: New test. * g++.dg/template/non-dependent16a.C: New test. * g++.dg/template/non-dependent17.C: New test.
2021-12-16c++: two-stage name lookup for overloaded operators [PR51577]Patrick Palka1-18/+28
In order to properly implement two-stage name lookup for dependent operator expressions, we need to remember the result of unqualified lookup of the operator at template definition time, and reuse that result rather than performing another unqualified lookup at instantiation time. Ideally we could just store the lookup in the expression directly, but as pointed out in r9-6405 this isn't really possible since we use the standard tree codes to represent most dependent operator expressions. We could perhaps create a new tree code to represent dependent operator expressions, with enough operands to store the lookup along with everything else, but that'd require a lot of careful work to make sure we handle this new tree code properly across the frontend. But currently type-dependent operator (and call) expressions are given an empty TREE_TYPE, which dependent_type_p treats as dependent, so this field is effectively unused except to signal that the expression is type-dependent. It'd be convenient if we could store the lookup there while preserving the dependent-ness of the expression. To that end, this patch creates a new kind of type, called DEPENDENT_OPERATOR_TYPE, which we give to dependent operator expressions and into which we can store the result of operator lookup at template definition time (DEPENDENT_OPERATOR_TYPE_SAVED_LOOKUPS). Since this type is always dependent (by definition), and since the frontend doesn't seem to care much about the exact type of a type-dependent expression, using this type in place of a NULL_TREE type seems to "just work"; only dependent_type_p and WILDCARD_TYPE_P need to be adjusted to return true for this new type. The rest of the patch mostly consists of adding the necessary plumbing to pass DEPENDENT_OPERATOR_TYPE_SAVED_LOOKUPS to add_operator_candidates, adjusting all callers of build_x_* appropriately, and removing the now unnecessary push_operator_bindings mechanism. In passing, this patch simplifies finish_constraint_binary_op to avoid using build_x_binary_op for building a binary constraint-expr; we don't need to consider operator overloads here, as the &&/|| inside a constraint effectively always has the built-in meaning (since atomic constraints must have bool type). This patch also makes FOLD_EXPR_OP yield a tree_code instead of a raw INTEGER_CST. Finally, this patch adds the XFAILed test operator-8.C which is about broken two-stage name lookup for rewritten non-dependent operator expressions, an existing bug that's otherwise only documented in build_new_op.

2021-12-14c++: processing_template_decl vs template depth [PR103408]Patrick Palka1-1/+1
We use processing_template_decl in two slightly different ways: as a flag to signal that we're dealing with templated trees, and as a measure of the current syntactic template nesting depth. This overloaded meaning of p_t_d is conceptually confusing and leads to bugs that we end up working around in an ad-hoc fashion. This patch replaces all uses of processing_template_decl that care about its magnitude to instead look at the depth of current_template_parms via a new macro current_template_depth. This allows us to eliminate 3 workarounds in the concepts code: two about non-templated requires-expressions (in constraint.cc) and one about lambdas inside constraints (in cp_parser_requires_clause_expression etc). This also fixes the testcase in PR103408 about auto(x) used inside a non-templated requires-expression. The replacement was mostly mechanical, aside from two issues: * In synthesize_implicit_template_parm, when introducing a new template parameter list for an abbreviated function template, we need to add the new level of current_template_parms sooner, before calling process_template_parm, since this latter function now looks at current_template_depth to determine the level of the new parameter. * In instantiate_class_template_1 after substituting a template friend declaration, we currently increment processing_template_decl around the call to make_friend_class so that the friend_depth computation within this subroutine yields a nonzero value. We could just replace this with an equivalent manipulation of current_template_depth, but this patch instead rewrites the friend_depth calculation within make_friend_class to not depend on p_t_d / c_t_d at all when called from instantiate_class_template_1.

front-end adjustments This patch implements three pieces of functionality: (1) Adjust array section mapping to have standards conforming behavior, mapping array sections should *NOT* also map the base-pointer: struct S { int *ptr; ... }; struct S s; Instead of generating this during gimplify: map(to:*_1 [len: 400]) map(attach:s.ptr [bias: 0]) Now, adjust to: (i.e. do not map the base-pointer together. The attach operation is still generated, and if s.ptr is already mapped prior, attachment will happen) The correct way of achieving the base-pointer-also-mapped behavior would be to use: (A small Fortran front-end patch to trans-openmp.c:gfc_trans_omp_array_section is also included, which removes generation of a GOMP_MAP_ALWAYS_POINTER for array types, which appears incorrect and causes a regression in libgomp.fortranlibgomp.fortran/struct-elem-map-1.f90) (2) Related to the first item above, are fixes in libgomp/target.c to not overwrite attached pointers when handling device<->host copies, mainly for the "always" case.

2021-12-03c++: Fix for decltype(auto) and parenthesized expr [PR103403]Marek Polacek1-14/+4
In r11-4758, I tried to fix this problem: int &&i = 0; decltype(auto) j = i; // should behave like int &&j = i; error wherein do_auto_deduction was getting confused with a REFERENCE_REF_P and it didn't realize its operand was a name, not an expression, and deduced the wrong type. Unfortunately that fix broke this: int&& r = 1; decltype(auto) rr = (r); where 'rr' should be 'int &' since '(r)' is an expression, not a name. But because I stripped the INDIRECT_REF with the r11-4758 change, we deduced 'rr's type as if decltype had gotten a name, resulting in 'int &&'. I suspect I thought that the REF_PARENTHESIZED_P check when setting 'bool id' in do_auto_deduction would handle the (r) case, but that's not the case; while the documentation for REF_PARENTHESIZED_P specifically says it can be set in INDIRECT_REF, we don't actually do so. This patch sets REF_PARENTHESIZED_P even on REFERENCE_REF_P, so that do_auto_deduction can use it. It also removes code in maybe_undo_parenthesized_ref that I think is dead -- and we don't hit it while running dg.exp. To adduce more data, it also looks dead here: https://splichal.eu/lcov/gcc/cp/semantics.c.gcov.html (It's dead since r9-1417.) Also add a fixed test for c++/81176.

2021-11-30Make OpenACC orphan gang reductions errorsCesar Philippidis1-0/+8
This patch promotes all OpenACC gang reductions on orphan loops as errors. Accord to the spec, orphan loops are those which are not lexically nested inside an OpenACC parallel or kernels regions. I.e., acc loops inside acc routines. At first I thought this could be a warning because the gang reduction finalizer uses an atomic update. However, because there is no synchronization between gangs, there is way to guarantee that reduction will have completed once a single gang entity returns from the acc routine call. gcc/c/ * c-typeck.c (c_finish_omp_clauses): Emit an error on orphan OpenACC gang reductions. gcc/cp/ * semantics.c (finish_omp_clauses): Emit an error on orphan OpenACC gang reductions. gcc/fortran/ * openmp.c (oacc_is_parallel, oacc_is_kernels): New 'static' functions.

2021-11-25c++: Implement C++23 P2128R6 - Multidimensional subscript operator [PR102611]Jakub Jelinek1-1/+2
The following patch implements the C++23 Multidimensional subscript operator P2128R6 paper. As C++20 and older only allow a single expression in between []s (albeit for C++20 with a deprecation warning if it is a comma expression) and even in C++23 and for the coming years I think the vast majority of subscript expressions will still have a single expression and even in C++23 it is quite special, as e.g. the builtin operator requires exactly one assignment expression, the patch attempts to optimize for that case and if possible not to slow down that common case (or use more memory for it). So, already during parsing it differentiates between that (uses a single index_exp tree in that case) and the new cases (zero or two+ expressions in the list), for which it sets index_exp to NULL_TREE and uses a releasing_vec instead similarly to how e.g. finish_call_expr uses it. In call.c it introduces new functions build_op_subscript{,_1} which are something in between build_new_op{,_1} and build_op_call{,_1}. The former requires fixed number of arguments (and the patch still uses it for the common case of subscript with exactly one index expression), the latter handles variable number of arguments but is too CALL_EXPR specific and handles various cases that are unnecessary for the subscript. Right now the subscript for 0 or 2+ expressions doesn't need to deal with builtin candidates and so is quite simple. As discussed in the paper, for backwards compatibility, if for 2+ index expressions build_op_subscript fails (called with tf_none) and the expressions together form a valid comma expression (again checked with tf_none), it is used that C++20-ish way with a pedwarn about it, but if even that fails, build_op_subscript is called again with standard complain flags to diagnose it in the new way. And similarly for the builtin case. The -Wcomma-subscript warning used to be enabled by default unless -Wno-deprecated.

This struct copy_body_data's hook is always NULL since merge of the tuples branch, before that it has been shortly used by the C++ FE during ctor/dtor cloning to chain the remapped blocks, but only very shortly, before transform_lang_insert_block was a bool and the call to insert_block was done through a langhook.

2021-11-18c++: Implement C++23 P0849R8 - auto(x) [PR103049]Marek Polacek1-0/+14
This patch implements P0849R8 which allows auto in a functional cast, the result of which is a prvalue. [expr.type.conv]/1 says that the type is determined by placeholder type deduction. We only accept 'auto', not 'decltype(auto)' -- that the type shall be auto comes from [dcl.type.auto.deduct]. Therefore the rules are like for [temp.deduct.call], deducing template arguments from a function call, so the result type will never be a reference, and we decay arrays/functions.

2021-11-11openmp: Add support for 2 argument num_teams clauseJakub Jelinek1-0/+47
In OpenMP 5.1, num_teams clause can accept either one expression as before, but it in that case changed meaning, rather than create <= expression teams it is now create == expression teams. Or it accepts two expressions separated by :, with the meaning that the first is low bound and second upper bound on how many teams should be created. The other ways to set number of teams are upper bounds with lower bound of 1. The following patch does parsing of this for C/C++. For host teams, we actually don't need to do anything further right now, we always create (pretend to create) exactly the requested number of teams, so we can just evaluate and throw away the lower bound for now. For teams nested in target, we don't guarantee that though and further work will be needed. In particular, omplower now turns the teams part of: struct S { S (); S (const S &); ~S (); int s; }; void bar (S &, S &); int baz (); _Pragma ("omp declare target to (baz)"); void foo (void) { S a, b; #pragma omp target private (a) map (b) { #pragma omp teams firstprivate (b) num_teams (baz ()) { bar (a, b); } } } into: retval.0 = baz (); retval.1 = retval.0; { unsigned int retval.3; struct S * D.2549; struct S b; retval.3 = (unsigned int) retval.1; D.2549 = .omp_data_i->b; S::S (&b, D.2549); #pragma omp teams num_teams(retval.1) firstprivate(b) shared(a) __builtin_GOMP_teams (retval.3, 0); { bar (&a, &b); } S::~S (&b); #pragma omp return(nowait) } IMHO we want a new API, say GOMP_teams3 which will take 3 arguments instead of 2 (the lower and upper bounds from num_teams and thread_limit) and will return a bool whether it should do the teams body or not. And, we should add right before outermost {} above while (__builtin_GOMP_teams3 ((unsigned) retval.1, (unsigned) retval.1, 0)) and remove the __builtin_GOMP_teams call. The current function performs exit equivalent (at least on NVPTX) which seems bad because that means the destructors of e.g. private variables on target aren't invoked, and at the current placement neither destructors of the already constructed privatized variables in teams. I'll do this next on the compiler side, but I'm afraid I'll need help with the nvptx and amdgcn implementations. E.g. for nvptx, we won't be able to use %ctaid.x . I think ideal would be to use a .shared integer variable for the omp_get_team_num value, but I don't have any experience with that, are .shared variables zero initialized by default, or do they have random value at start? PTX docs say they aren't initializable. 2021-11-11 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.h (OMP_CLAUSE_NUM_TEAMS_EXPR): Rename to ... (OMP_CLAUSE_NUM_TEAMS_UPPER_EXPR): ... this.

2021-09-08c++/102228 - make lookup_anon_field O(1)Richard Biener1-0/+8
For the testcase in PR101555 lookup_anon_field takes the majority of parsing time followed by get_class_binding_direct/fields_linear_search which is PR83309. The situation with anon aggregates is particularly dire when we need to build accesses to their members and the anon aggregates are nested. There for each such access we recursively build sub-accesses to the anon aggregate FIELD_DECLs bottom-up, DFS searching for them. That's inefficient since as I believe there's a 1:1 relationship between anon aggregate types and the FIELD_DECL used to place them. The patch below does away with the search in lookup_anon_field and instead records the single FIELD_DECL in the anon aggregate types lang-specific data, re-using the RTTI typeinfo_var field. That speeds up the compile of the testcase with -fsyntax-only from about 4.5s to slightly less than 1s. I tried to poke holes into the 1:1 relationship idea with my C++ knowledge but failed (which might not say much). It also leaves a hole for the case when the C++ FE itself duplicates such type and places it at a semantically different position. I've tried to poke holes into it with the duplication mechanism I understand (templates) but failed. 2021-09-08 Richard Biener <rguenther@suse.de> PR c++/102228 gcc/cp/ * cp-tree.h (ANON_AGGR_TYPE_FIELD): New define. * decl.c (fixup_anonymous_aggr): Wipe RTTI info put in place on invalid code. * decl2.c (reset_type_linkage): Guard CLASSTYPE_TYPEINFO_VAR access. * module.cc (trees_in::read_class_def): Likewise.

2021-08-17c++: Implement P0466R5 __cpp_lib_is_layout_compatible compiler helpers ↵Jakub Jelinek1-0/+268
[PR101539] The following patch implements __is_layout_compatible trait and __builtin_is_corresponding_member helper function for the std::is_corresponding_member template function. As the current definition of layout compatible type has various problems, which result e.g. in corresponding members in layout compatible types having different member offsets, the patch anticipates some changes to the C++ standard: 1) class or enumeral types aren't layout compatible if they have different alignment or size 2) if two members have different offsets, they can't be corresponding members ([[no_unique_address]] with empty types can change that, or alignas on the member decls) 3) in unions, bitfields can't correspond to non-unions, or bitfields can't correspond to bitfields with different widths, or members with [[no_unique_address]] can't correspond to members without that attribute __builtin_is_corresponding_member for anonymous structs (GCC extension) will recurse into the anonymous structs. For anonymous unions it will emit a sorry if it can't prove such member types can't appear in the anonymous unions or anonymous aggregates in that union, because corresponding member is defined only using common initial sequence which is only defined for std-layout non-union class types and so I have no idea what to do otherwise in that case. 2021-08-17 Jakub Jelinek <jakub@redhat.com> PR c++/101539 gcc/c-family/ * c-common.h (enum rid): Add RID_IS_LAYOUT_COMPATIBLE. * c-common.c (c_common_reswords): Add __is_layout_compatible. gcc/cp/ * cp-tree.h (enum cp_trait_kind): Add CPTK_IS_LAYOUT_COMPATIBLE.

2021-08-12openmp: Add support for OpenMP 5.1 masked constructJakub Jelinek1-0/+23
This construct has been introduced as a replacement for master construct, but unlike that construct is slightly more general, has an optional clause which allows to choose which thread will be the one running the region, it can be some other thread than the master (primary) thread with number 0, or it could be no threads or multiple threads (then of course one needs to be careful about data races). It is way too early to deprecate the master construct though, we don't even have OpenMP 5.0 fully implemented, it has been deprecated in 5.1, will be also in 5.2 and removed in 6.0. But even then it will likely be a good idea to just -Wdeprecated warn about it and still accept it. The patch also contains something I should have done much earlier, for clauses that accept some integral expression where we only care about the value, forces during gimplification that value into either a min invariant (as before), SSA_NAME or a fresh temporary, but never e.g. a user VAR_DECL, so that for those clauses we don't need to worry about adjusting it. 2021-08-12 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.def (OMP_MASKED): New tree code. * tree-core.h (enum omp_clause_code): Add OMP_CLAUSE_FILTER. * tree.h (OMP_MASKED_BODY, OMP_MASKED_CLAUSES, OMP_MASKED_COMBINED, OMP_CLAUSE_FILTER_EXPR): Define. * tree.c (omp_clause_num_ops): Add OMP_CLAUSE_FILTER entry.

2021-08-12openmp: Diagnose syntax mismatches between declare target and end declare targetJakub Jelinek1-2/+2
OpenMP 5.1 says: For any directive that has a paired end directive, including those with a begin and end pair, both directives must use either the attribute syntax or the pragma syntax. The following patch enforces it with the only pair so far recognized in C++ (Fortran has many, but on the other side doesn't have attribute syntax). While I initially wanted to use vec<bool, va_gc> *member; in there, that unfortunately doesn't work, one gets linker errors and I guess it is fixable, but for begin declare target we'll need a struct anyway to store device_type etc. 2021-08-12 Jakub Jelinek <jakub@redhat.com> * cp-tree.h (omp_declare_target_attr): New type.

2021-07-30c++: Implement P0466R5 __cpp_lib_is_pointer_interconvertible compiler ↵Jakub Jelinek1-3/+111
helpers [PR101539] The following patch attempts to implement the compiler helpers for libstdc++ std::is_pointer_interconvertible_base_of trait and std::is_pointer_interconvertible_with_class template function. For the former __is_pointer_interconvertible_base_of trait that checks first whether base and derived aren't non-union class types that are the same ignoring toplevel cv-qualifiers, otherwise if derived is unambiguously derived from base without cv-qualifiers, derived being a complete type, and if so, my limited understanding of any derived object being pointer-interconvertible with base subobject IMHO implies (because one can't inherit from unions or unions can't inherit) that we check if derived is standard layout type and we walk bases of derived recursively, stopping on a class that has any non-static data members and check if any of the bases is base. On class with non-static data members no bases are compared already. Upon discussions, this is something that maybe should have been changed in the standard with CWG 2254 and the patch no longer performs this and assumes all base subobjects of standard-layout class types are pointer-interconvertible with the whole class objects. The latter is implemented using a FE __builtin_is_pointer_interconvertible_with_class, but because on the library side it will be a template function, the builtin takes ... arguments and only during folding verifies it has a single argument with pointer to member type. The initial errors IMHO can only happen if one uses the builtin incorrectly by hand, the template function should ensure that it has exactly a single argument that has pointer to member type. Otherwise, again with my limited understanding of what the template function should do and pointer-interconvertibility, it folds to false for pointer-to-member-function, errors if basetype of the OFFSET_TYPE is incomplete, folds to false for non-std-layout non-union basetype, then finds the first non-static data member in the basetype or its bases (by ignoring DECL_FIELD_IS_BASE FIELD_DECLs that are empty, recursing into DECL_FIELD_IS_BASE FIELD_DECLs type that are non-empty (I think std layout should ensure there is at most one), for unions checks if membertype is same type as any of the union FIELD_DECLs, for non-unions the first other FIELD_DECL only, and for anonymous aggregates similarly (union vs. non-union) but recurses into the anon aggr types with std layout check for anon structures. If membertype doesn't match the type of first non-static data member (or for unions any of the members), then the builtin folds to false, otherwise the built folds to a check whether the argument is equal to OFFSET_TYPE of 0 or not, either at compile time if it is constant (e.g. for constexpr folding) or at runtime otherwise. As I wrote in the PR, I've tried my testcases with MSVC on godbolt that claims to implement it, and https://godbolt.org/z/3PnjM33vM for the first testcase shows it disagrees with my expectations on static_assert (std::is_pointer_interconvertible_base_of_v<D, F>); static_assert (std::is_pointer_interconvertible_base_of_v<E, F>); static_assert (!std::is_pointer_interconvertible_base_of_v<D, G>); static_assert (!std::is_pointer_interconvertible_base_of_v<D, I>); static_assert (std::is_pointer_interconvertible_base_of_v<H, volatile I>); Is that a bug in my patch or is MSVC buggy on these (or mix thereof)? https://godbolt.org/z/aYeYnne9d shows the second testcase, here it differs on: static_assert (std::is_pointer_interconvertible_with_class<F, int> (&F::b)); static_assert (std::is_pointer_interconvertible_with_class<I, int> (&I::g)); static_assert (std::is_pointer_interconvertible_with_class<L, int> (&L::b)); static_assert (std::is_pointer_interconvertible_with_class (&V::a)); static_assert (std::is_pointer_interconvertible_with_class (&V::b)); Again, my bug, MSVC bug, mix thereof? According to Jason the <D, G>, <D, I> case are the subject of the CWG 2254 above discussed change and the rest are likely MSVC bugs. Oh, and there is another thing, the standard has an example: struct A { int a; }; // a standard-layout class struct B { int b; }; // a standard-layout class struct C: public A, public B { }; // not a standard-layout class static_assert( is_pointer_interconvertible_with_class( &C::b ) ); // Succeeds because, despite its appearance, &C::b has type // “pointer to member of B of type int”. static_assert( is_pointer_interconvertible_with_class<C>( &C::b ) ); // Forces the use of class C, and fails. It seems to work as written with MSVC (second assertion fails), but fails with GCC with the patch: /tmp/1.C:22:57: error: no matching function for call to ‘is_pointer_interconvertible_with_class<C>(int B::*)’ 22 | static_assert( is_pointer_interconvertible_with_class<C>( &C::b ) ); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~ /tmp/1.C:8:1: note: candidate: ‘template<class S, class M> constexpr bool std::is_pointer_interconvertible_with_class(M S::*)’ 8 | is_pointer_interconvertible_with_class (M S::*m) noexcept | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /tmp/1.C:8:1: note: template argument deduction/substitution failed: /tmp/1.C:22:57: note: mismatched types ‘C’ and ‘B’ 22 | static_assert( is_pointer_interconvertible_with_class<C>( &C::b ) ); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~ the second int argument isn't deduced. This boils down to: template <class S, class M> bool foo (M S::*m) noexcept; struct A { int a; }; struct B { int b; }; struct C : public A, public B {}; bool a = foo (&C::b); bool b = foo<C, int> (&C::b); bool c = foo<C> (&C::b); which with /std:c++20 or -std=c++20 is accepted by latest MSVC and ICC but rejected by GCC and clang (in both cases on the last line). Is this a GCC/clang bug in argument deduction (in that case I think we want a separate PR), or a bug in ICC/MSVC and the standard itself that should specify in the examples both template arguments instead of just the first?

2021-06-24openmp: in_reduction clause support on target constructJakub Jelinek1-43/+68
This patch adds support for in_reduction clause on target construct, though for now only for synchronous targets (without nowait clause). The encountering thread in that case runs the target task and blocks until the target region ends, so it is implemented by remapping it before entering the target, initializing the private copy if not yet initialized for the current thread and then using the remapped addresses for the mapping addresses. For nowait combined with in_reduction the patch contains a hack where the nowait clause is ignored. To implement it correctly, I think we would need to create a new private variable for the in_reduction and initialize it before doing the async target and adjust the map addresses to that private variable and then pass a function pointer to the library routine with code where the callback would remap the address to the current threads private variable and use in_reduction combiner to combine the private variable we've created into the thread's copy. The library would then need to make sure that the routine is called in some thread participating in the parallel (and not in an unshackeled thread). 2021-06-24 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.h (OMP_CLAUSE_MAP_IN_REDUCTION): Document meaning for OpenMP. * gimplify.c (gimplify_scan_omp_clauses): For OpenMP map clauses with OMP_CLAUSE_MAP_IN_REDUCTION flag partially defer gimplification of non-decl OMP_CLAUSE_DECL.

This patch implements that. A minor annoyance was handling macros, in libstdc++ we have reference operator[](size_type __pos) { __glibcxx_assert(__pos <= size()); ... } wherein __glibcxx_assert expands to if (__builtin_is_constant_evaluated() && !bool(__pos <= size()) ... but I'm of a mind to not warn on that.

2021-06-07c++: alias with same name as base fn [PR91706]Jason Merrill1-2/+4
This is a bit complex. Looking up c<T> in the definition of D::c finds C::c, OK. Looking up c in the definition of E finds D::c, OK. Since the alias is not dependent, we strip it from the template argument, leaving using E = A<decltype(c<T>())>; where 'c' still refers to C::c. But instantiating E looks up 'c' again and finds D::c, which isn't a function, and sadness ensues. I think the bug here is looking up 'c' in D at instantiation time; the declaration we found before is not dependent. This seems to happen because baselink_for_fns gets BASELINK_BINFO wrong; it is supposed to be the base where lookup found the functions, C in this case. gcc/cp/ChangeLog: PR c++/91706 * semantics.c (baselink_for_fns): Fix BASELINK_BINFO. gcc/testsuite/ChangeLog: PR c++/91706 * g++.dg/template/lookup17.C: New test.

target [PR99928] The reduction clause should be copied as map (tofrom: ) to combined target if present, but as we need different handling of array sections between map and reduction, doing that during gimplification would be harder.

2021-05-21openmp: Fix up firstprivate+lastprivate clause handling [PR99928]Jakub Jelinek1-0/+27
The C/C++ clause splitting happens very early during construct parsing, but only the FEs later on handle possible instantiations, non-static member handling and array section lowering. In the OpenMP 5.0/5.1 rules, whether firstprivate is added to combined target depends on whether it isn't also mentioned in lastprivate or map clauses, but unfortunately I think such checks are much better done only when the FEs perform all the above mentioned changes. So, this patch arranges for the firstprivate clause to be copied or moved to combined target construct (as before), but sets flags on that clause, which tell the FE *finish_omp_clauses and the gimplifier it has been added only conditionally and let the FEs and gimplifier DTRT for these. 2021-05-21 Jakub Jelinek <jakub@redhat.com> PR middle-end/99928 gcc/ * tree.h (OMP_CLAUSE_FIRSTPRIVATE_IMPLICIT_TARGET): Define. * gimplify.c (enum gimplify_omp_var_data): Fix up GOVD_MAP_HAS_ATTACHMENTS value, add GOVD_FIRSTPRIVATE_IMPLICIT.

2021-04-29c++: Fix up detach clause vs. data-sharing clause checking [PR100319]Jakub Jelinek1-3/+3
The standard says that "The event-handle will be considered as if it was specified on a firstprivate clause." which means that it can't be explicitly specified in some other data-sharing clause. The checking is implemented correctly for C, but for C++ when detach_seen is true (i.e. the construct had detach clause) we were comparing OMP_CLAUSE_DECL (c) with t, which was previously initialized to OMP_CLAUSE_DECL (c), which means it complained about any explicit data-sharing clause on the same construct with a detach clause. Fixed by remembering the detach clause in detach_seen (instead of a boolean flag) and comparing against its OMP_CLAUSE_DECL. 2021-04-29 Jakub Jelinek <jakub@redhat.com> PR c++/100319 * semantics.c (finish_omp_clauses): Fix up check that variable mentioned in detach clause doesn't appear in data-sharing clauses. * c-c++-common/gomp/task-detach-3.c: New test.
2021-04-14c++: non-static member, array bound, sizeof [PR93314]Jason Merrill1-0/+10
N2253 allowed referring to non-static data members without an object in unevaluated operands like that of sizeof, but in a constant-expression context like an array bound or template argument within such an unevaluated operand we do actually need a value, so that permission cannot apply. gcc/cp/ChangeLog: PR c++/93314 * semantics.c (finish_id_expression_1): Clear cp_unevaluated_operand for a non-static data member in a constant-expression. gcc/testsuite/ChangeLog: PR c++/93314 * g++.dg/parse/uneval1.C: New test.
2021-04-13c++: debug location of variable cleanups [PR88742]Jason Merrill1-0/+19
PR49951 complained about the debugger jumping back to the declaration of a local variable when we run its destructor. That was fixed in 4.7, but broke again in 4.8. PR58123 fixed an inconsistency in the behavior, but not the jumping around. This patch addresses the issue by setting EXPR_LOCATION on a cleanup destructor call to the location of the closing brace of the compound-statement, or whatever token ends the scope of the variable. The change to cp_parser_compound_statement is so input_location is the } rather than the ; of the last substatement. gcc/cp/ChangeLog: PR c++/88742 PR c++/49951 PR c++/58123 * semantics.c (set_cleanup_locs): New.
