2021-12-16c++: two-stage name lookup for overloaded operators [PR51577]Patrick Palka1-131/+2
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.

Now that GCC is compiled as C++11 there is no need to keep the C++03 implementation of gnu::unique_ptr. This removes the unique-ptr.h header and replaces it with <memory> in system.h, and changes the INCLUDE_UNIQUE_PTR macro to INCLUDE_MEMORY.

2021-12-09pch: Add support for relocation of the PCH data [PR71934]Jakub Jelinek1-2/+2
The following patch adds support for relocation of the PCH blob on PCH restore if we don't manage to get the preferred map slot for it. The GTY stuff knows where all the pointers are, after all it relocates it once during PCH save from the addresses where it was initially allocated to addresses in the preferred map slot. But, if we were to do it solely using GTY info upon PCH restore, we'd need another set of GTY functions, which I think would make it less maintainable and I think it would also be more costly at PCH restore time. Those functions would need to call something to add bias to pointers that haven't been marked yet and make sure not to add bias to any pointer twice. So, this patch instead builds a relocation table (sorted list of addresses in the blob which needs relocation) at PCH save time, stores it in a very compact form into the gch file and upon restore, adjusts pointers in GTY roots (that is right away in the root structures) and the addresses in the relocation table. The cost on stdc++.gch/O2g.gch (previously 85MB large) is about 3% file size growth, there are 2.5 million pointers that need relocation in the gch blob and the relocation table uses uleb128 for address deltas and needs ~1.01 bytes for one address that needs relocation, and about 20% compile time during PCH save (I think it is mainly because of the need to qsort those 2.5 million pointers). On PCH restore, if it doesn't need relocation (the usual case), it is just an extra fread of sizeof (size_t) data and fseek (in my tests real time on vanilla tree for #include <bits/stdc++.h> CU was ~0.175s and with the patch but no relocation ~0.173s), while if it needs relocation it took ~0.193s, i.e. 11.5% slower. Without PCH that #include <bits/stdc++.h> int i; testcase compiles with -O2 -g in ~1.199s, i.e. 6.2 times slower than PCH with relocation and 6.9 times than PCH without relocation. The discovery of the pointers in the blob that need relocation is done in the relocate_ptrs hook which does the pointer relocation during PCH save. Unfortunately, I had to make one change to the gengtype stuff due to the nested_ptr feature of GTY, which some libcpp headers and stringpool.c use. The relocate_ptrs hook had 2 arguments, pointer to the pointer and a cookie. When relocate_ptrs is done, in most cases it is called solely on the subfields of the current object, so e.g. if ((void *)(x) == this_obj) op (&((*x).u.fld[0].rt_rtx), cookie); so relocate_ptrs can assert that ptr_p is within the state->ptrs[state->ptrs_i]->obj .. state->ptrs[state->ptrs_i]->obj+state->ptrs[state->ptrs_i]->size-sizeof(void*) range and compute from that the address in the blob which will need relocation (state->ptrs[state->ptrs_i]->new_addr is the new address given to it and ptr_p-state->ptrs[state->ptrs_i]->obj is the relative offset. Unfortunately, for nested_ptr gengtype emits something like: { union tree_node * x0 = ((*x).val.node.node) ? HT_IDENT_TO_GCC_IDENT (HT_NODE (((*x).val.node.node))) : NULL; if ((void *)(x) == this_obj) op (&(x0), cookie); (*x).val.node.node = (x0) ? CPP_HASHNODE (GCC_IDENT_TO_HT_IDENT ((x0))) : NULL; } so relocate_ptrs is called with an address of some temporary variable and so doesn't know where the pointer will finally be. So, I've added another argument to relocate_ptrs (and to gt_pointer_operator). For the most common case I pass NULL as the new middle argument to that function, first one remains pointer to the pointer that needs adjustment and last the cookie. The NULL seems to be cheap to compute and short in the gt*.[ch] files and stands for ptr_p is an address within the this_obj's range, remember its address. For the nested_ptr case, the new middle argument contains actual address of the pointer that might need to be relocated, so instead of the above op (&(x0), &((*x).val.node.node), cookie); in there. And finally, e.g. for the reorder case I need a way to tell restore_ptrs to ignore a particular address for the relocation purposes and only treat it the old way. I've used for that the case when the first and second arguments are equal. In order to enable support for mapping PCH as fallback at different addresses than the preferred ones, a small change is needed to the host pch_use_address hooks. One change I've done to all of them is the change of the type of the first argument from void * to void *&, such that the actual address can be told to the callers (or shall I instead use void **?), but another change that still needs to be done in them if they want the relocation is actually not fail if they couldn't get a preferred address, but instead modify what the first argument refers to. I've done that only for host-linux.c and Iain is testing similar change for host-darwin.c. Didn't change hpux, netbsd, openbsd, solaris, mingw32 or the fallbacks because I can't test those.

There are other code paths that store error_mark_node into DECL_LOCAL_DECL_ALIAS, with the intent to differentiate the cases where we haven't yet tried to push it into the namespace scope (NULL) and one where we have tried it but it failed (error_mark_node), but looking around, there are other spots where we call functions or do processing which doesn't tolerate error_mark_node. So, the first hunk with the testcase fixes the testcase, the others fix what I've spotted and the fix was easy to figure out (there are I think 3 other spots mainly for function multiversioning). 2021-10-20 Jakub Jelinek <jakub@redhat.com> PR c++/102642 * name-lookup.c (push_local_extern_decl_alias): Don't call set_decl_tls_model on error_mark_node. * decl.c (make_rtl_for_nonlocal_decl): Don't call set_user_assembler_name on error_mark_node. * parser.c (cp_parser_oacc_declare): Ignore DECL_LOCAL_DECL_ALIAS if it is error_mark_node.

2021-06-04c++: Fix up attribute handling in methods in templates [PR100872]Jakub Jelinek1-2/+5
The following testcase FAILs because a dependent (late) attribute is never tsubsted. While the testcase is OpenMP, I think it is a generic C++ FE problem that could affect any other dependent attribute. apply_late_template_attributes documents that it relies on /* save_template_attributes puts the dependent attributes at the beginning of the list; find the non-dependent ones. */ The "operator binding" attributes that are sometimes added are added to the head of DECL_ATTRIBUTES list though and because it doesn't have ATTR_IS_DEPENDENT set it violates this requirement. The following patch fixes it by adding that attribute after all ATTR_IS_DEPENDENT attributes. I'm not 100% sure if DECL_ATTRIBUTES can't be shared by multiple functions (e.g. the cdtor clones), but the code uses later remove_attribute which could break that too. Other option would be to copy_list the ATTR_IS_DEPENDENT portion of the DECL_ATTRIBUTES list if we need to do this, that would be the same as this patch but replace that *ap = op_attr; at the end with *ap = NULL_TREE; DECL_ATTRIBUTES (cfn) = chainon (copy_list (DECL_ATTRIBUTES (cfn)), op_attr); Or perhaps set ATTR_IS_DEPENDENT on the "operator bindings" attribute, though it would need to be studied what would it try to do with the attribute during tsubst. 2021-06-04 Jakub Jelinek <jakub@redhat.com> PR c++/100872 * name-lookup.c (maybe_save_operator_binding): Add op_attr after all ATTR_IS_DEPENDENT attributes in the DECL_ATTRIBUTES list rather than to the start. * g++.dg/gomp/declare-simd-8.C: New test.

This unconditionally enables the maybe_save_operator_binding mechanism for all function templates, so that when resolving a dependent operator expression from a function template we ignore later-declared namespace-scope bindings that weren't visible at template definition time. This patch additionally makes the mechanism apply to dependent comma and compound-assignment operator expressions. Note that this doesn't fix the testcases in PR83035 or PR99692 because there the dependent operator expressions aren't at function scope. I'm not sure how adapt this mechanism for these testcases, since although we'll in both testcases have a TEMPLATE_DECL to associate the lookup result with, at instantiation time we won't have an appropriate binding level to push to. gcc/cp/ChangeLog: PR c++/51577 * name-lookup.c (maybe_save_operator_binding): Unconditionally enable for all function templates, not just generic lambdas.

2021-04-07c++: using overloaded with local decl [PR92918]Jason Merrill1-1/+1
The problem here was that the lookup for 'impl' when parsing the template only found the using-declaration, not the member function declaration. This happened because when trying to add the member function declaration, push_class_level_binding_1 saw that the current binding was a USING_DECL and the new value is an overload, and decided to just return success. That 'return true' dates back to r69921. In https://gcc.gnu.org/pipermail/gcc-patches/2003-July/110632.html Nathan mentions that we only push dependent USING_DECLs, which is no longer the case; now that we retain more USING_DECLs, handling this case like the other overloaded function cases seems like the obvious solution. gcc/cp/ChangeLog: PR c++/92918 * name-lookup.c (push_class_level_binding_1): Do overload a new function with a previous using-declaration. gcc/testsuite/ChangeLog: PR c++/92918 * g++.dg/lookup/using66.C: New test.
2021-03-26c++: imported templates and alias-template changes [PR 99283]Nathan Sidwell1-2/+4
During development of modules, I had difficulty deciding whether the module flags of a template should live on the decl_template_result, the template_decl, or both. I chose the latter, and require them to be consistent. This and a few other defects show how hard that consistency is. Hence this patch move to holding the flags on the template-decl-result decl. That's the entity various bits of the parser have at the appropriate time. Once needs STRIP_TEMPLATE in a bunch of places, which this patch adds. Also a check that we never give a TEMPLATE_DECL to the module flag accessors. This left a problem with how I was handling template aliases. These were in two parts -- separating the TEMPLATE_DECL from the TYPE_DECL. That seemed somewhat funky, but development showed it necessary. Of course, that causes problems if the TEMPLATE_DECL cannot contain 'am imported' information. Investigating now shows that we do not need to treat them separately. By reverting a bit of template instantiation machinery that caused the problem, we're back on course. I think what has happened is that between then and now, other typedef fixes have corrected the underlying problem this separation was working around. It allows a bunch of cleanup in the decl streamer, as we no longer have to handle a null TEMPLATE_DECL_RESULT. PR c++/99283 gcc/cp/ * cp-tree.h (DECL_MODULE_CHECK): Ban TEMPLATE_DECL.

2021-03-04c++: Redesign pending entity handling [PR 99170]Nathan Sidwell1-55/+4
This patch addresses 99170. with modules (and in particular header units), one module can provide a (maybe nested) class or template and another module can provide a definition or (maybe partial) specialization of said entity, or member thereof. when both are imported into a 3rd TU, and that TU instantiates or uses the class, it needs to stream in those entities (in general). But how does it key those entities to the original? It can't /just/ use the entity index, because, when header-units and/or partitions are in play, the entity index /is not unique/. I had two complicated schemes that tried to unify that, but it failed. Here's a simpler scheme. Such pending entities are keyed to the namespace and identifier of the namespace-scope entity that contains them. Thus the final TU needs to find that entity and look in a hash table for lists of sections that need loading just before instantiating a template or looking inside a class. I would like to make this more efficient, but given the complex scheme failed, I'm shooting for correctness right now. There will be a follow up patch to complete the cleanup this enables.

2021-02-19c++: Incorrect module-number ordering [PR 98741]Nathan Sidwell1-0/+5
One of the very strong invariants in modules is that module numbers are allocated such that (other than the current TU), all imports have lesser module numbers, and also that the binding vector is only appended to with increasing module numbers. This broke down when module-directives became a thing and the preprocessing became entirely decoupled from parsing. We'd load header units and their macros (but not symbols of course) during preprocessing. Then we'd load named modules during parsing. This could lead to the situation where a header unit appearing after a named import had a lower module number than the import. Consequently, if they both bound the same identifier, the binding vector would be misorderd and bad things happen. This patch restores a pending import queue I previously had, but in simpler form (hurrah). During preprocessing we queue all module-directives and when we meet one for a header unit we do the minimal loading for all of the queue, so they get appropriate numbering. Then we load the preprocessor state for the header unit. PR c++/98741 gcc/cp/ * module.cc (pending_imports): New. (declare_module): Adjust test condition. (name_pending_imports): New.

2021-02-17c++: More set_identifier_type_value fixing [PR 99116]Nathan Sidwell1-18/+14
My recent change looked under template_parms in two places, but that was covering up a separate problem. We were attempting to set the identifier_type_value of a template_parm into the template_parm scope. The peeking stopped us doing that, but confused poplevel, leaving an identifier value lying around. This fixes the underlying problem in do_pushtag -- we only need to set the identifier_type_value directly when we're in a template_parm scope (a later pushdecl will push the actual template_decl). for non-class non-template-parm bindings do_pushdecl already ends up manipulating identifier_type_value correctly.

With modules one can have using-decls refering to their own scope. This is the way to export things from the GMF or from an import. The problem was I was using current_ns == CP_DECL_CONTEXT (decl) to determine whether a decl should be registered in a namespace level or not.

2021-02-12Expunge namespace-scope IDENTIFIER_TYPE_VALUE & global_type_name [PR 99039]Nathan Sidwell1-105/+29
IDENTIFIER_TYPE_VALUE and friends is a remnant of G++'s C origins. It holds elaborated types on identifier-nodes. While this is fine for C and for local and class-scopes in C++, it fails badly for namespaces. In that case a marker 'global_type_node' was used, which essentially signified 'this is a namespace-scope type *somewhere*', and you'd have to do a regular name_lookup to find it. As the parser and substitution machinery has avanced over the last 25 years or so, there's not much outside of actual name-lookup that uses that. Amusingly the IDENTIFIER_HAS_TYPE_VALUE predicate will do an actual name-lookup and then users would repeat that lookup to find the now-known to be there type. Rather late I realized that this interferes with the lazy loading of module entities, because we were setting IDENTIFIER_TYPE_VALUE to global_type_node. But we could be inside some local scope where that identifier is bound to some local type. Not good! Rather than add more cruft to look at an identifier's shadow stack and alter that as necessary, this takes the approach of removing the existing cruft. We nuke the few places outside of name lookup that use IDENTIFIER_TYPE_VALUE. Replacing them with either proper name lookups, alternative sequences, or in some cases asserting that they (no longer) happen. Class template instantiation was calling pushtag after setting IDENTIFIER_TYPE_VALUE in order to stop pushtag creating an implicit typedef and pushing it, but to get the bookkeeping it needed. Let's just do the bookkeeping directly. Then we can stop having a 'bound at namespace-scope' marker at all, which means lazy loading won't screw up local shadow stacks. Also, it simplifies set_identifier_type_value_with_scope, as it never needs to inspect the scope stack. When developing this patch, I discovered a number of places we'd put an actual namespace-scope type on the type_value slot, rather than global_type_node. You might notice this is killing at least two 'why are we doing this?' comments. While this doesn't fix the two PRs mentioned, it is a necessary step.

In r11-4690 we removed the call to finish_nonmember_using_decl in tsubst_expr/DECL_EXPR in the USING_DECL block. This was done not to perform name lookup twice for a non-dependent using-decl, which sounds sensible. However, finish_nonmember_using_decl also pushes the decl's bindings which we still have to do so that we can find the USING_DECL's name later. In this case, we've got a USING_DECL N::operator<< that we are tsubstituting. We already looked it up while parsing the template "foo", and lookup_using_decl stashed the OVERLOAD it found into USING_DECL_DECLS. Now we just have to update the IDENTIFIER_BINDING of the identifier for operator<< with the overload the name is bound to.

2020-11-13c++: Implement C++20 'using enum'. [PR91367]Jason Merrill1-92/+164
This feature allows the programmer to import enumerator names into the current scope so later mentions don't need to use the fully-qualified name. These usings are not subject to the usual restrictions on using-decls: in particular, they can move between class and non-class scopes, and between classes that are not related by inheritance. This last caused difficulty for our normal approach to using-decls within a class hierarchy, as we assume that the class where we looked up a used declaration is derived from the class where it was first declared. So to simplify things, in that case we make a clone of the CONST_DECL in the using class. Thanks to Nathan for the start of this work: in particular, the lookup_using_decl rewrite. The changes to dwarf2out revealed an existing issue with the D front-end: we were doing the wrong thing for importing a D CONST_DECL, because dwarf2out_imported_module_or_decl_1 was looking through it to its type, expecting it to be an enumerator, but in one case in thread.d, the constant had type int. Adding the ability to import a C++ enumerator also fixed that, but that led to a crash in force_decl_die, which didn't know what to do with a CONST_DECL. So now it does.

2020-11-09c++: ADL refactorNathan Sidwell1-51/+105
This refactors the ADL lookup. It just so happens the refactoring makes dropping modules in simpler :) We break apart the namespace and class fn processing, and move scope iteration to an outer function. It'll also become possible to find the same enum in multiple place, so we need to handle that idempotently. gcc/cp/ * cp-tree.h (LOOKUP_FOUND_P): Add ENUMERAL_TYPE. * name-lookup.c (class name_lookup): Add comments.

2020-11-09c++: Consistently expose singleton overloadsNathan Sidwell1-3/+11
This is a patch from my name-lookup overhaul. I noticed the parser and one path in name-lookup looked through an overload of a single known decl. It seems more consistent to do that in both paths through name-lookup, and not in the parser itself. gcc/cp/ * name-lookup.c (lookup_qualified_name): Expose an overload of a singleton with known type. (lookup_name_1): Just check the overload's type to expose it. * parser.c (cp_parser_lookup_name): Do not do that check here.
2020-11-06core: Rename DECL_IS_BUILTIN -> DECL_IS_UNDECLARED_BUILTINNathan Sidwell1-3/+3
In cleaning up C++'s handling of hidden decls, I renamed its DECL_BUILTIN_P, which checks for loc == BUILTINS_LOCATION to DECL_UNDECLARED_BUILTIN_P, because the location gets updated, if user source declares the builtin, and the predicate no longer holds. The original name was confusing me. (The builtin may still retain builtin properties in the redeclaration, and other predicates can still detect that.) I discovered that tree.h had its own variant 'DECL_IS_BUILTIN', which behaves in (almost) the same manner. And therefore has the same mutating behaviour. This patch deletes the C++ one, and renames tree.h's to DECL_IS_UNDECLARED_BUILTIN, to emphasize its non-constantness. I guess _IS_ wins over _P gcc/ * tree.h (DECL_IS_BUILTIN): Rename to ...

2020-10-27c++: Kill nested_udtsNathan Sidwell1-210/+4
During the implementation of modules I added myself a note to implement nested_udt handling. It wasn't obvious to me what they were for and nothing seemed to be broken in ignoring them. I figured something would eventually pop up and I'd add support. Nothing popped up. Investigating on trunk discovered 3 places where we look at the nested-udts. I couldn't figure how the one in lookup_field_r was needed -- surely the regular lookup would find the type. It turned out that code was unreachable. So we can delete it. Next in do_type_instantiation, we walk the nested-utd table instantiating types. But those types are also on the TYPE_FIELDS list, which we've just iterated over. So I can move the handling into that loop. The final use is in handling structs that have a typedef name for linkage purposes. Again, we can just iterate over TYPE_FIELDS. (As commented, we probably don't need to do even that, as a DR, whose number I forget, requires such structs to only have C-like things in them. But I didn't go that far. Having removed all the uses of nested-udts, I can remove their creation from name-lookup, and as the only instance of a binding_table object, we can remove all that code too. gcc/cp/ * cp-tree.h (struct lang_type): Delete nested_udts field. (CLASSTYPE_NESTED_UTDS): Delete. * name-lookup.h (binding_table, binding_entry): Delete typedefs. (bt_foreach_proc): Likewise. (struct binding_entry_s): Delete.

2020-10-20c++: block-scope extern decl with default argsNathan Sidwell1-0/+46
In adding the DECL_LOCAL_DECL handling, I'd forgotten that the parm-decls also need cloning -- and resetting of their DECL_CONTEXT. Also, any default args need droping when adding an alias, as those are not propagated. The std's not totally clear on this latter point when there's no exising namespace decl, but that seems like the right thing and is what clang does. gcc/cp/ * name-lookup.c (push_local_extern_decl_alias): Reconstextualize alias' parm decls. Drop any default args. gcc/testsuite/ * g++.dg/lookup/local-extern.C: New.
