2022-01-08c++: default mem-init of array [PR103946]Jason Merrill1-4/+1
In the patch for PR92385 I added asserts to see if we tried to make a vec_init of a vec_init, but didn't see any in regression testing. This testcase is one case, which seems reasonable: we create a VEC_INIT_EXPR for the aggregate initializer, and then again to express the actual initialization of the member. We already do similar collapsing of TARGET_EXPR. So let's just remove the asserts.

2022-01-06c++: clean up ref-extended temp on throwing dtor [PR53868]Jason Merrill1-0/+1
We have wrap_temporary_cleanups to handle the EH region nesting problems between cleanups for complete variables and cleanups for temporaries used in their construction, but we weren't calling it for temporaries extended from binding to a reference. We still don't want this for array cleanups (since my PR94041 fix), so I move that exception from initialize_local_var to wrap_temporary_cleanups.

2022-01-06c++: keep destroying array after one dtor throws [PR66451]Jason Merrill1-2/+16
When we're cleaning up an array, if one destructor throws, we should still try to clean up the rest of the array. We can use TRY_CATCH_EXPR for this, instead of a TARGET_EXPR like my other recent patches, because a destructor call can't involve any temporaries that need to live longer. I thought about only doing this when we call build_vec_delete_1 from build_vec_init, but it seems appropriate for delete-expressions as well; we've said that the array's lifetime is over, it makes sense to keep trying to destroy it. The standard isn't clear, but clang seems to agree with me. PR c++/66451 gcc/cp/ChangeLog: * init.c (build_vec_delete_1): Handle throwing dtor.

2022-01-06c++: temporary lifetime with array aggr init [PR94041]Jason Merrill1-35/+49
The previous patch fixed temporary lifetime for aggregate initialization of classes; this one extends that fix to arrays. This specifically reverses my r74790, the patch for PR12253, which was made wrong when these semantics were specified in DR201. Since the array cleanup region encloses the regions for any temporaries, we don't need to add an additional region for the array object itself in either initialize_local_var or split_nonconstant_init; we do, however, need to tell split_nonconstant_init how to disable the cleanup once an enclosing object is fully constructed, at which point we want to run that destructor instead.

2022-01-06c++: loop over array elts w/o explicit init [PR92385]Jason Merrill1-1/+10
The PR complains that initializing a large array with {} takes a long time to compile; this was because digest_init would turn {} into a long CONSTRUCTOR with an initializer for each element, instead of more sensibly generating a loop. The standard doesn't specify this implementation, but it does allow for it by specifying that a temporary created "when a default constructor is called to initialize an element of an array with no corresponding initializer" is destroyed "before the construction of the next array element, if any." rather than living until the end of the complete object initialization as usual. This change is also needed before the PR94041 fix extends the lifetime of temporaries from elements with explicit initializers. To implement this, I change digest_init so that in cases where initialization of trailing array elements isn't constant, we return a VEC_INIT_EXPR instead of a bare CONSTRUCTOR; when it is encountered later, we call build_vec_init to generate the actual initialization code.

2022-01-06c++: don't preevaluate new-initializerJason Merrill1-30/+8

2021-11-18c++: Implement -Wuninitialized for mem-initializers (redux) [PR19808]Marek Polacek1-13/+181
2021 update: Last year I posted a version of this patch: <https://gcc.gnu.org/pipermail/gcc-patches/2020-November/559162.html> but it didn't make it in. The main objection seemed to be that the patch tried to do too much, and overlapped with the ME uninitialized warnings. Since the patch used walk_tree without any data flow info, it issued false positives for things like a(0 ? b : 42) and similar. I'll admit I've been dreading resurrecting this because of the lack of clarity about where we should warn about what. On the other hand, I think we really should do something about this. So I've simplified the original patch as much as it seemed reasonable. For instance, it doesn't even attempt to handle cases like "a((b = 42)), c(b)" -- for these I simply give up for the whole mem-initializer (but who writes code like that, anyway?). I also give up when a member is initialized with a function call, because we don't know what the call could do. See Wuninitialized-17.C, for which clang emits a false positive but we don't. I remember having a hard time dealing with initializer lists in my previous patch, so now I only handle simple a{b} cases, but no more. It turned out that this abridged version still warns about 90% cases where users would expect a warning. More complicated cases are left for the ME, which, for unused inline functions, will only warn with -fkeep-inline-functions, but so be it. (This is bug 21678.) This patch implements the long-desired -Wuninitialized warning for member initializer lists, so that the front end can detect bugs like struct A { int a; int b; A() : b(1), a(b) { } }; where the field 'b' is used uninitialized because the order of member initializers in the member initializer list is irrelevant; what matters is the order of declarations in the class definition. I've implemented this by keeping a hash set holding fields that are not initialized yet, so at first it will be {a, b}, and after initializing 'a' it will be {b} and so on. Then I use walk_tree to walk the initializer and if we see that an uninitialized object is used, we warn. Of course, when we use the address of the object, we may not warn: struct B { int &r; int *p; int a; B() : r(a), p(&a), a(1) { } // ok }; Likewise, don't warn in unevaluated contexts such as sizeof. Classes without an explicit initializer may still be initialized by their default constructors; whether or not something is considered initialized is handled in perform_member_init, see member_initialized_p.

2021-06-01c++: value-init vs zero-init in expand_aggr_init_1 [PR65816]Patrick Palka1-2/+2
In the case of value-initializing an object of class type T, [dcl.init.general]/8 says: - if T has either no default constructor ([class.default.ctor]) or a default constructor that is user-provided or deleted, then the object is default-initialized; - otherwise, the object is zero-initialized and ... if T has a non-trivial default constructor, the object is default-initialized; But when determining whether to first zero-initialize the object, expand_aggr_init_1 incorrectly considers the user-providedness of _all_ constructors rather than only that of the _default_ constructors. This causes us to skip the zero-initialization step when the class type has a defaulted default constructor alongside a user-defined constructor. It seems the predicate type_has_non_user_provided_default_constructor accurately captures the above rule for when to first perform a zero-initialization during value-initialization, so this patch adjusts expand_aggr_init_1 to use this predicate instead.

2021-02-12Expunge namespace-scope IDENTIFIER_TYPE_VALUE & global_type_name [PR 99039]Nathan Sidwell1-12/+0
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.

2021-02-11c++: Fix zero initialization of flexible array members [PR99033]Jakub Jelinek1-9/+11
array_type_nelts returns error_mark_node for type of flexible array members and build_zero_init_1 was placing an error_mark_node into the CONSTRUCTOR, on which e.g. varasm ICEs. I think there is nothing erroneous on zero initialization of flexible array members though, such arrays should simply get no elements, like they do if such classes are constructed (everything except when some larger initializer comes from an explicit initializer). So, this patch handles [] arrays in zero initialization like [0] arrays and fixes handling of the [0] arrays - the tree_int_cst_equal (max_index, integer_minus_one_node) check didn't do what it thought it would do, max_index is typically unsigned integer (sizetype) and so it is never equal to a -1. What the patch doesn't do and maybe would be desirable is if it returns error_mark_node for other reasons let the recursive callers not stick that into CONSTRUCTOR but return error_mark_node instead. But I don't have a testcase where that would be needed right now. 2021-02-11 Jakub Jelinek <jakub@redhat.com> PR c++/99033 * init.c (build_zero_init_1): Handle zero initialiation of flexible array members like initialization of [0] arrays.

2021-01-26c++: constexpr and empty fields [PR97566]Jason Merrill1-1/+1
In the discussion of PR98463, Jakub pointed out that in C++17 and up, cxx_fold_indirect_ref_1 could use the field we build for an empty base. I tried implementing that, but it broke one of the tuple tests, so I did some more digging. To start with, I generalized the PR98463 patch to handle the case where we do have a field, for an empty base or [[no_unique_address]] member. This is enough also for the no-field case because the member of the empty base must itself be an empty field; if it weren't, the base would not be empty. I looked for related PRs and found 97566, which was also fixed by the patch. After some poking around to figure out why, I noticed that the testcase had been breaking because E, though an empty class, has an ABI nvsize of one byte, and we were giving the [[no_unique_address]] FIELD_DECL that DECL_SIZE, whereas in build_base_field_1 empty base fields always get DECL_SIZE zero, and various places were relying on that to recognize empty fields. So I adjusted both the size and the checking. When I adjusted check_bases I wondered if we were correctly handling bases with only empty data members, but it appears we do. I'm deferring the cxx_fold_indirect_ref_1 change until stage 1, as I don't think it actually fixes anything. gcc/cp/ChangeLog: PR c++/97566 PR c++/98463 * class.c (layout_class_type): An empty field gets size 0.

2021-01-22c++: Fix up ubsan false positives on references [PR95693]Jakub Jelinek1-4/+1
Alex' 2 years old change to build_zero_init_1 to return NULL pointer with reference type for references breaks the sanitizers, the assignment of NULL to a reference typed member is then instrumented before it is overwritten with a non-NULL address later on. That change has been done to fix error recovery ICE during process_init_constructor_record, where we: if (TYPE_REF_P (fldtype)) { if (complain & tf_error) error ("member %qD is uninitialized reference", field); else return PICFLAG_ERRONEOUS; } a few lines earlier, but then continue and ICE when build_zero_init returns NULL. The following patch reverts the build_zero_init_1 change and instead creates the NULL with reference type constants during the error recovery.

2020-12-23c++: Fix up floating point complex handling in build_zero_init_1 [PR98353]Jakub Jelinek1-1/+1
While the gimplifier patch I've just committed fixed an ICE, in some cases like on the committed testcase cp folding doesn't happen after build_zero_init_1 because it is called already during gimplification. For the scalar types, if we want to use convert, the problem with complex floats is that it returns a COMPLEX_EXPR with FLOAT_EXPR arguments which have INTEGER_CST 0 as argument. As fold isn't recursive, it doesn't do anything in that case, we need to first fold those FLOAT_EXPRs to REAL_CST 0.0 and only afterwards the COMPLEX_EXPR can be folded into COMPLEX_CST with 0.0 arguments. This patch instead just uses build_zero_cst that creates the zero constant for any scalar types (and more) directly, instead of going through multiple hops. 2020-12-23 Jakub Jelinek <jakub@redhat.com> PR c++/98353 * init.c (build_zero_init_1): Use build_zero_cst for SCALAR_TYPE_P zero initializers.

2020-11-19c++: Fix array new with value-initialization [PR97523]Marek Polacek1-1/+5
Since my r11-3092 the following is rejected with -std=c++20: struct T { explicit T(); }; void fn(int n) { new T[1](); } with "would use explicit constructor 'T::T()'". It is because since that change we go into the P1009 block in build_new (array_p is false, but nelts is non-null and we're in C++20). Since we only have (), we build a {} and continue to build_new_1, which then calls build_vec_init and then we error because the {} isn't CONSTRUCTOR_IS_DIRECT_INIT. For (), which is value-initializing, we want to do what we were doing before: pass empty init and let build_value_init take care of it. For various reasons I wanted to dig a little bit deeper into this, and as a result, I'm adding a test for [expr.new]/24 (and checked that out current behavior matches clang++). gcc/cp/ChangeLog: PR c++/97523 * init.c (build_new): When value-initializing an array new, leave the INIT as an empty vector. gcc/testsuite/ChangeLog: PR c++/97523 * g++.dg/expr/anew5.C: New test. * g++.dg/expr/anew6.C: New test.

2020-09-09c++: Further tweaks for new-expression and paren-init [PR77841]Marek Polacek1-31/+23
This patch corrects our handling of array new-expression with ()-init: new int[4](1, 2, 3, 4); should work even with the explicit array bound, and new char[3]("so_sad"); should cause an error, but we weren't giving any. Fixed by handling array new-expressions with ()-init in the same spot where we deduce the array bound in array new-expression. I'm now always passing STRING_CSTs to build_new_1 wrapped in { } which allowed me to remove the special handling of STRING_CSTs in build_new_1. And since the DIRECT_LIST_INIT_P block in build_new_1 calls digest_init, we report errors about too short arrays. reshape_init now does the {"foo"} -> "foo" transformation even for CONSTRUCTOR_IS_PAREN_INIT, so no need to do it in build_new. I took a stab at cp_complete_array_type's "FIXME: this code is duplicated from reshape_init", but calling reshape_init there, I ran into issues with has_designator_problem: when we reshape an already reshaped CONSTRUCTOR again, d.cur.index has been filled, so we think that we have a user-provided designator (though there was no designator in the source code), and report an error. gcc/cp/ChangeLog: PR c++/77841 * decl.c (reshape_init): If we're initializing a char array from a string-literal that is enclosed in braces, unwrap it. * init.c (build_new_1): Don't handle string-initializers here.

2020-09-03c++: Fix P0960 in member init list and array [PR92812]Marek Polacek1-7/+19
This patch nails down the remaining P0960 case in PR92812: struct A { int ar[2]; A(): ar(1, 2) {} // doesn't work without this patch }; Note that when the target object is not of array type, this already works: struct S { int x, y; }; struct A { S s; A(): s(1, 2) { } // OK in C++20 }; because build_new_method_call_1 takes care of the P0960 magic. It proved to be quite hairy. When the ()-list has more than one element, we can always create a CONSTRUCTOR, because the code was previously invalid. But when the ()-list has just one element, it gets all kinds of difficult. As usual, we have to handle a("foo") so as not to wrap the STRING_CST in a CONSTRUCTOR. Always turning x(e) into x{e} would run into trouble as in c++/93790. Another issue was what to do about x({e}): previously, this would trigger "list-initializer for non-class type must not be parenthesized". I figured I'd make this work in C++20, so that given struct S { int x, y; }; you can do S a[2]; [...] A(): a({1, 2}) // initialize a[0] with {1, 2} and a[1] with {} It also turned out that, as an extension, we support compound literals: F (): m((S[1]) { 1, 2 }) so this has to keep working as before. Moreover, make sure not to trigger in compiler-generated code, like =default, where array assignment is allowed. I've factored out a function that turns a TREE_LIST into a CONSTRUCTOR to simplify handling of P0960. paren-init35.C also tests this with vector types. gcc/cp/ChangeLog: PR c++/92812 * cp-tree.h (do_aggregate_paren_init): Declare. * decl.c (do_aggregate_paren_init): New.

2020-09-01c++: Allow new char[4]{"foo"} [PR77841]Marek Polacek1-0/+6
Currently, we allow new char[]{"foo"}, but not new char[4]{"foo"}. We should accept the latter too: [dcl.init.list]p3.3 says to treat this as [dcl.init.string]. We were rejecting this code because we never called reshape_init before the digest_init in build_new_1. reshape_init handles [dcl.init.string] by unwrapping the STRING_CST from its enclosing { }, and digest_init assumes that reshape_init has been called for aggregates anyway, and an array is an aggregate. gcc/cp/ChangeLog: PR c++/77841 * init.c (build_new_1): Call reshape_init. gcc/testsuite/ChangeLog: PR c++/77841 * g++.dg/cpp0x/initlist-new4.C: New test.
2020-08-31c++: Implement P1009: Array size deduction in new-expressions.Marek Polacek1-4/+51
This patch implements C++20 P1009, allowing code like new double[]{1,2,3}; // array bound will be deduced Since this proposal makes the initialization rules more consistent, it is applied to all previous versions of C++ (thus, effectively, all the way back to C++11). My patch is based on Jason's patch that handled the basic case. I've extended it to work with ()-init and also the string literal case. Further testing revealed that to handle stuff like new int[]{t...}; in a template, we have to consider such a NEW_EXPR type-dependent. Obviously, we first have to expand the pack to be able to deduce the number of elements in the array. Curiously, while implementing this proposal, I noticed that we fail to accept new char[4]{"abc"}; so I've assigned 77841 to self. I think the fix will depend on the build_new_1 hunk in this patch.

We don't elide a copy from a function returning a class by value into a base because that can overwrite data laid out in the tail padding of the base class; we need to handle [[no_unique_address]] fields the same way, or we ICE when the middle-end wants to create a temporary object of a TYPE_NEEDS_CONSTRUCTING type. This means that we can't always express initialization of a field with INIT_EXPR from a TARGET_EXPR the way we usually do, so I needed to change several places that were assuming that was sufficient.

2020-07-30c++: decl_constant_value and unsharing [PR96197]Patrick Palka1-11/+23
In the testcase from the PR we're seeing excessive memory use (> 5GB) during constexpr evaluation, almost all of which is due to the call to decl_constant_value in the VAR_DECL/CONST_DECL branch of cxx_eval_constant_expression. We reach here every time we evaluate an ARRAY_REF of a constexpr VAR_DECL, and from there decl_constant_value makes an unshared copy of the VAR_DECL's initializer. But unsharing here is unnecessary because callers of cxx_eval_constant_expression already unshare its result when necessary. To fix this excessive unsharing, this patch adds a new defaulted parameter unshare_p to decl_really_constant_value and decl_constant_value so that callers can control whether to unshare. As a simplification, we can also move the call to unshare_expr in constant_value_1 outside of the loop, since doing unshare_expr on a DECL_P is a no-op. Now that we no longer unshare the result of decl_constant_value and decl_really_constant_value from cxx_eval_constant_expression, memory use during constexpr evaluation for the testcase from the PR falls from ~5GB to 15MB according to -ftime-report. gcc/cp/ChangeLog: PR c++/96197 * constexpr.c (cxx_eval_constant_expression) <case CONST_DECL>: Pass false to decl_constant_value and decl_really_constant_value so that they don't unshare their result. * cp-tree.h (decl_constant_value): New declaration with an added bool parameter.
