2021-12-16c++: two-stage name lookup for overloaded operators [PR51577]Patrick Palka1-6/+6
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.

2021-10-05c++: defaulted <=> with bitfields [PR102490]Jakub Jelinek1-87/+153
The testcases in the patch are either miscompiled or ICE with checking, because the defaulted operator== is synthesized too early (but only if constexpr), when the corresponding class type is still incomplete type. The problem is that at that point the bitfield FIELD_DECLs still have as TREE_TYPE their underlying type rather than integral type with their precision and when layout_class_type is called for the class soon after that, it changes those types but the COMPONENT_REFs type stay the way that they were during the operator== synthesize_method type and the middle-end is then upset by the mismatch of types. As what exact type will be given isn't just a one liner but quite long code especially for over-sized bitfields, I think it is best to just not synthesize the comparison operators so early and call defaulted_late_check for them once again as soon as the class is complete. This is also a problem for virtual operator<=>, where we need to compare the noexcept-specifier to validate the override before the class is complete. Rather than try to defer that comparison, maybe_instantiate_noexcept now calls maybe_synthesize_method, which calls build_comparison_op in non-defining mode if the class isn't complete yet. In that situation we also might not have base fields yet, so we look in the binfo for the bases.

2021-09-14c++: Fix __is_*constructible/assignable for templates [PR102305]Jakub Jelinek1-0/+1
is_xible_helper returns error_mark_node (i.e. false from the traits) for abstract classes by testing ABSTRACT_CLASS_TYPE_P (to) early. Unfortunately, as the testcase shows, that doesn't work on class templates that haven't been instantiated yet, ABSTRACT_CLASS_TYPE_P for them is false until it is instantiated, which is done when the routine later constructs a dummy object with that type. The following patch fixes this by calling complete_type first, so that ABSTRACT_CLASS_TYPE_P test will work properly, while keeping the handling of arrays with unknown bounds, or incomplete types where it is done currently. 2021-09-14 Jakub Jelinek <jakub@redhat.com> PR c++/102305 * method.c (is_xible_helper): Call complete_type on to. * g++.dg/cpp0x/pr102305.C: New test.

2021-05-19c++: ICE with <=> fallback [PR100367]Jason Merrill1-7/+35
Here, when genericizing lexicographical_compare_three_way, we haven't yet walked the operands, so (a == a) still sees ADDR_EXPR <a>, but this is after we've changed the type of a to REFERENCE_TYPE. When we try to fold (a == a) by constexpr evaluation, the constexpr code doesn't understand trying to take the address of a reference, and we end up crashing. Fixed by avoiding constexpr evaluation in genericize_spaceship, by using fold_build2 instead of build_new_op on scalar operands. Class operands should have been expanded during parsing.

2021-04-01c++: GC collects live data when synthesizing operator== [PR99831]Marek Polacek1-1/+6
Here we crash in reshape_init because we're accessing ggc_freed & poisoned data: since r277865 in defaulted_late_check we call synthesize_method here: if (kind == sfk_comparison) { /* If the function was declared constexpr, check that the definition qualifies. Otherwise we can define the function lazily. */ if (DECL_DECLARED_CONSTEXPR_P (fn) && !DECL_INITIAL (fn)) synthesize_method (fn); return; } which in this test triggers when we're processing the string<"a">{} in the static_assert. First, we create a CONSTRUCTOR for the "{}" in cp_parser_functional_cast, then we call finish_compound_literal which calls complete_type and that results in garbage collection, which then frees the CONSTRUCTOR {} we created when parsing the braced-list in string<"a">{} -- at this point, it's not referenced by anything. (That's not the case for 'type' in finish_compound_literal: the symbol table contains a node for operator==, so ggc_mark_roots goes and marks the fn decl, its type, its arguments etc., as used, so we don't collect it.)

2021-03-25c++: ICE on invalid with inheriting constructors [PR94751]Marek Polacek1-5/+17
This is an ICE on invalid where we crash because since r269032 we keep error_mark_node around instead of using noexcept_false_spec when things go wrong; see the walk_field_subobs hunk. We crash in deduce_inheriting_ctor which calls synthesized_method_walk to deduce the exception-specification, but fails to do so in this case, because the testcase is invalid so get_nsdmi returns error_mark_node for the member 'c', and per r269032 the error_mark_node propagates back to deduce_inheriting_ctor which subsequently calls build_exception_variant whereon we crash. I think we should return early if the deduction fails and I decided to call mark_used to get an error right away instead of hoping that it would get called later. My worry is that we could forget that there was an error and think that we just deduced noexcept(false). And then I noticed that the test still crashes in C++98. Here again we failed to deduce the exception-specification in implicitly_declare_fn, but nothing reported an error between synthesized_method_walk and the assert. Well, not much we can do except calling synthesized_method_walk again, this time in the verbose mode and making sure that we did get an error. gcc/cp/ChangeLog: PR c++/94751 * call.c (build_over_call): Maybe call mark_used in case deduce_inheriting_ctor fails and return error_mark_node. * cp-tree.h (deduce_inheriting_ctor): Adjust declaration. * method.c (deduce_inheriting_ctor): Return bool if the deduction fails.

http://eel.is/c++draft/class.compare.default#6 says for the expanded list of subobjects: "In that list, any subobject of array type is recursively expanded to the sequence of its elements, in the order of increasing subscript." but build_comparison_op just tried to compare the whole arrays, which failed and therefore the defaulted comparison was deleted. The following patch instead compares the array elements, and if info.defining, adds runtime loops around it so that it iterates over increasing subscripts. For flexible array members it punts, we don't know how large those will be, for zero sized arrays it doesn't even try to compare the elements, because if there are no elements, there is nothing to compare, and for [1] arrays it will not emit a loop because it is enough to use [0] array ref to cover everything. 2020-12-21 Jakub Jelinek <jakub@redhat.com> PR c++/93480 * method.c (common_comparison_type): If comps[i] is a TREE_LIST, use its TREE_VALUE instead.

I thought I had implemented P1186R3, but apparently I didn't read it closely enough to understand the point of the paper, namely that for a defaulted operator<=>, if a member type doesn't have a viable operator<=>, we will use its operator< and operator== if the defaulted operator has an specific comparison category as its return type; the compiler can't guess if it should be strong_ordering or something else, but the user can make that choice explicit.

2020-10-02c++: cleanup ctor_omit_inherited_parms [PR97268]Nathan Sidwell1-8/+28
ctor_omit_inherited_parms was being somewhat abused. What I'd missed is that it checks for a base-dtor name, before proceeding with the check. But we ended up passing it that during cloning before we'd completed the cloning. It was also using DECL_ORIGIN to get to the in-charge ctor, but we sometimes zap DECL_ABSTRACT_ORIGIN, and it ends up processing the incoming function -- which happens to work. so, this breaks out a predicate that expects to get the incharge ctor, and will tell you whether its base ctor will need to omit the parms. We call that directly during cloning. Then the original fn is essentially just a wrapper, but uses DECL_CLONED_FUNCTION to get to the in-charge ctor. That uncovered abuse in add_method, which was happily passing TEMPLATE_DECLs to it. Let's not do that. add_method itself contained a loop mostly containing an 'if (nomatch) continue' idiom, except for a final 'if (match) {...}' check, which itself contained instances of the former idiom. I refactored that to use the former idiom throughout. In doing that I found a place where we'd issue an error, but then not actually reject the new member. gcc/cp/ * cp-tree.h (base_ctor_omit_inherited_parms): Declare. * class.c (add_method): Refactor main loop, only pass fns to ctor_omit_inherited_parms.

2020-05-06c++: Don't synthesize sfk_comparison method multiple times [PR94907]Jakub Jelinek1-1/+1
On the following testcase we ICE, because synthesize_method is called twice on the same sfk_comparison method fndecl, the first time it works fine because start_preparsed_function in that case sets both current_function_decl and cfun, but second time it is called it only sets the former and keeps cfun NULL, so we ICE when trying to store current_function_returns_value. I think it is just wrong to call synthesize_method multiple times, and most synthesize_method callers avoid that by not calling it if DECL_INITIAL is already set, so this patch does that too. 2020-05-06 Jakub Jelinek <jakub@redhat.com> PR c++/94907 * method.c (defaulted_late_check): Don't call synthesize_method on constexpr sfk_comparison if it has been called on it already. * g++.dg/cpp2a/spaceship-synth8.C: New test.

2020-04-10c++: make __is_constructible work with paren-init of aggrs [PR94149]Marek Polacek1-3/+39
In C++20 this is well-formed: using T = int[2]; T t(1, 2); which means that std::is_constructible_v<int[2], int, int> should be true. But constructible_expr immediately returned the error_mark_node when it saw a list with more than one element. To give accurate results in C++20, we have to try initializing the aggregate from a parenthesized list of values. To not repeat the same mistake as in c++/93790, if there's only one element, I'm trying {} only when () didn't succeed. is_constructible5.C verifies this. In paren-init24.C std::is_nothrow_constructible_v doesn't work due to error: invalid 'static_cast' from type 'int' to type 'int [1]' and error: functional cast to array type 'int [2]' This needs to be fixed in libstdc++.

In this PR we're emitting -Wnoexcept warnings about potentially-throwing NSDMIs when computing the noexcept specification of a class's defaulted default constructor. Although these warnings are in some sense valid, this patch takes the route of suppressing them, because: 1. the warning message is confusing in its current form; 2. warning for 'struct C { B b = B(); };' but not for 'struct C { B b; };' is inconsistent; and 3. emitting a warning here arguably doesn't fall under the umbrella of -Wnoexcept, whose documentation says it warns only when a noexcept-expression evaluates to false, but there are no noexcept-expressions here. gcc/cp/ChangeLog: PR c++/93805 * except.c (maybe_noexcept_warning): Add TODO comment. * method.c (walk_field_subobs): Pass tf_none to expr_noexcept_p. gcc/testsuite/ChangeLog: PR c++/93805 * g++.dg/warn/Wnoexcept2.C: New test.

2019-11-05Implement C++20 operator<=>.Jason Merrill1-22/+713
There are three major pieces to this support: scalar operator<=>, synthesis of comparison operators, and rewritten/reversed overload resolution (e.g. a < b becomes 0 > b <=> a). Unlike other defaulted functions, where we use synthesized_method_walk to semi-simulate what the definition of the function will be like, this patch determines the characteristics of a comparison operator by trying to define it. My handling of non-dependent rewritten operators in templates can still use some work: build_min_non_dep_op_overload can't understand the rewrites and crashes, so I'm avoiding it for now by clearing *overload. This means we'll do name lookup again at instantiation time, which can incorrectly mean a different result. I'll poke at this more in stage 3. I'm leaving out a fourth section ("strong structural equality") even though I've implemented it, because it seems likely to change radically tomorrow.

(cp_build_addr_expr_1): Reject taking address of immediate function outside of immediate function. * decl.c (validate_constexpr_redeclaration): Diagnose consteval vs. non-consteval or vice versa redeclaration. Use SET_DECL_IMMEDIATE_FUNCTION_P if new_decl is immediate function. (check_tag_decl): Use %qs with keyword string to simplify translation. Handle ds_consteval. (start_decl): Adjust diagnostics for static or thread_local variables in immediate functions. (grokfndecl): Call sorry_at on virtual consteval. Use %qs with keyword to string to simplify translation. Diagnose consteval main. Use SET_DECL_IMMEDIATE_FUNCTION_P for consteval. (grokdeclarator): Handle consteval. Use %qs with keyword strings to simplify translation. Use separate ifs instead of chained else if for invalid specifiers. For constinit clear constinit_p rather than constexpr_p. * constexpr.c (find_immediate_fndecl): New function. (cxx_eval_outermost_constant_expr): Allow consteval calls returning void. Diagnose returning address of immediate function from consteval evaluation. (fold_non_dependent_expr_template): Add OBJECT argument, pass it through to cxx_eval_outermost_constant_expr. (fold_non_dependent_expr): Add OBJECT argument, pass it through to fold_non_dependent_expr_template. (fold_non_dependent_init): Adjust fold_non_dependent_expr_template caller. * method.c (defaulted_late_check): Adjust diagnostics for consteval. * lambda.c (maybe_add_lambda_conv_op): Copy over DECL_DECLARED_CONSTEXPR_P and DECL_IMMEDIATE_FUNCTION_P bits from callop to both artificial functions. * init.c (build_value_init): Don't do further processing if build_special_member_call returned a TREE_CONSTANT.
