2021-11-24middle-end: Convert bitclear <imm> + cmp<cc> #0 into cm<cc2> <imm2>Tamar Christina1-0/+53
This optimizes the case where a mask Y which fulfills ~Y + 1 == pow2 is used to clear a some bits and then compared against 0 into one without the masking and a compare against a different bit immediate. We can do this for all unsigned compares and for signed we can do it for comparisons of EQ and NE: (x & (~255)) == 0 becomes x <= 255. Which for leaves it to the target to optimally deal with the comparison. This transformation has to be done in the mid-end because in RTL you don't have the signs of the comparison operands and if the target needs an immediate this should be floated outside of the loop.

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.

2021-11-11openmp: Add support for 2 argument num_teams clauseJakub Jelinek1-1/+1
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.

2021-11-09Introduce build_debug_expr_declMartin Jambor1-0/+12
This patch introduces a helper function build_debug_expr_decl to build DEBUG_EXPR_DECL tree nodes in the most common way and replaces with a call of this function all code pieces which build such a DECL itself and sets its mode to the TYPE_MODE of its type. There still remain 11 instances of open-coded creation of a DEBUG_EXPR_DECL which set the mode of the DECL to something else. It would probably be a good idea to figure out that has any effect and if not, convert them to calls of build_debug_expr_decl too.

Initialize automatic variables with either a pattern or with zeroes to increase the security and predictability of a program by preventing uninitialized memory disclosure and use. GCC still considers an automatic variable that doesn't have an explicit initializer as uninitialized, -Wuninitialized will still report warning messages on such automatic variables. With this option, GCC will also initialize any padding of automatic variables that have structure or union types to zeroes.

2021-09-01C-family: Add attribute 'unavailable'.Iain Sandoe1-0/+72
If an interface is marked 'deprecated' then, presumably, at some point it will be withdrawn and no longer available. The 'unavailable' attribute makes it possible to mark up interfaces to indicate this status. It is used quite extensively in some codebases where a single set of headers can be used to permit code generation for multiple system versions. From a configuration perspective, it also allows a compile test to determine that an interface is missing - rather than requiring a link test. The implementation follows the pattern of attribute deprecated, but produces an error (where deprecation produces a warning). This attribute has been implemented in clang for some years.

In r245300 (commit 02889d23ee3b02854dff203dd87b9a25e30b61b4) "OpenACC tile clause support" that one had changed to three operands, similar to 'OMP_CLAUSE_COLLAPSE'.

2021-08-12openmp: Add support for OpenMP 5.1 masked constructJakub Jelinek1-0/+3
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.

2021-05-18PR100281 C++: Fix SImode pointer handlingAndreas Krebbel1-11/+18
The problem appears to be triggered by two locations in the front-end where non-POINTER_SIZE pointers aren't handled right now. 1. An assertion in strip_typedefs is triggered because the alignment of the types don't match. This in turn is caused by creating the new type with build_pointer_type instead of taking the type of the original pointer into account. 2. An assertion in cp_convert_to_pointer is triggered which expects the target type to always have POINTER_SIZE. gcc/cp/ChangeLog: PR c++/100281 * cvt.c (cp_convert_to_pointer): Use the size of the target pointer type. * tree.c (cp_build_reference_type): Call cp_build_reference_type_for_mode with VOIDmode.

The fix for PR94775 added more strict checking for type reuse to check_aligned_type, specifically matching TYPE_USER_ALIGN. But then build_aligned_type sets TYPE_USER_ALIGN on the built variant so if the type we build an aligned variant for does not have TYPE_USER_ALIGN we'll never re-use the newly created aligned variant. This results in ~35000 identical variants being created for polyhedron doduc.

2021-01-28tree: Don't reuse types if TYPE_USER_ALIGN differ [PR94775]Marek Polacek1-1/+3
A year ago I submitted this patch: ~~ Here we trip on the TYPE_USER_ALIGN (t) assert in strip_typedefs: it gets "const d[0]" with TYPE_USER_ALIGN=0 but the result built by build_cplus_array_type is "const char[0]" with TYPE_USER_ALIGN=1. When we strip_typedefs the element of the array "const d", we see it's a typedef_variant_p, so we look at its DECL_ORIGINAL_TYPE, which is char, but we need to add the const qualifier, so we call cp_build_qualified_type -> build_qualified_type where get_qualified_type checks to see if we already have such a type by walking the variants list, which in this case is: char -> c -> const char -> const char -> d -> const d Because check_base_type only checks TYPE_ALIGN and not TYPE_USER_ALIGN, we choose the first const char, which has TYPE_USER_ALIGN set. If the element type of an array has TYPE_USER_ALIGN, the array type gets it too. So we can make check_base_type stricter. I was afraid that it might make us reuse types less often, but measuring showed that we build the same amount of types with and without the patch, while bootstrapping. ~~ However, the patch broke a few tests on STRICT_ALIGNMENT platforms and had to be reverted. This is another try. The original patch is kept unchanged, but I added the finalize_type_size hunk that ought to fix the STRICT_ALIGNMENT issues. The problem is that finalize_type_size can clear TYPE_USER_ALIGN on the main variant of a type, but doesn't clear it on any of the variants. Then we end up with types which share the same TYPE_MAIN_VARIANT, but their TYPE_CANONICAL differs and then the usual "canonical types differ for identical types" follows. I've created alignas19.C to exercise this scenario. What happens is: - when parsing the class S we create a type S in xref_tag, - we see alignas(8) so common_handle_aligned_attribute sets T_U_A in S, - we parse the member function fn and build_memfn_type creates a copy of S to add const; this variant has T_U_A set, - we finish_struct S which calls layout_class_type -> finish_record_type -> finalize_size_type where we reset T_U_A in S (but const S keeps it), - finish_non_static_data_member for arr calls maybe_dummy_object with type = S, - maybe_dummy_object calls same_type_ignoring_top_level_qualifiers_p to check if S and TREE_TYPE (current_class_ref), which is const S, are the same, - same_type_ignoring_top_level_qualifiers_p creates cv-unqualified versions of the passed types. Previously we'd use our main variant S when stripping "const S" of const, but since the T_U_A flags don't match (check_base_type), we create a new variant S'. Then we crash in comptypes because S and S' have the same TYPE_MAIN_VARIANT but different TYPE_CANONICALs. With my patch we'll clear T_U_A for S's variants too, and then instead of S' we'll just use S. gcc/ChangeLog: PR c++/94775 * stor-layout.c (finalize_type_size): If we reset TYPE_USER_ALIGN in the main variant, maybe reset it in its variants too. * tree.c (check_base_type): Return true only if TYPE_USER_ALIGN match.

2020-12-10drop __builtin_ from __clear_cache libnameAlexandre Oliva1-1/+1
I made a cut&pasto in my previous patch for tree.c, causing platforms that have CLEAR_INSN_CACHE defined, and none of the internal __clear_cache expansion overriders, to issue calls to symbols named __builtin___clear_cache rather than __clear_cache, on languages other than those in the C family. Oops.

2020-12-04vec: Simplify use with C++11 range-based 'for'.Jason Merrill1-1/+1
It looks cleaner if we can use a vec* directly as a range for the C++11 range-based 'for' loop, without needing to indirect from it, and also works with null pointers. The change in cp_parser_late_parsing_default_args is an example of how this can be used to simplify a simple loop over a vector. Reverse or subset iteration will require adding range adaptors. I deliberately didn't format the new overloads for etags since they are trivial. gcc/ChangeLog: * vec.h (begin, end): Add overloads for vec*. * tree.c (build_constructor_from_vec): Remove *. gcc/cp/ChangeLog: * decl2.c (clear_consteval_vfns): Remove *. * pt.c (do_auto_deduction): Remove *. * parser.c (cp_parser_late_parsing_default_args): Change loop to use range 'for'.
2020-12-03fix __builtin___clear_cache overrider falloutAlexandre Oliva1-0/+6
Machines that had CLEAR_CACHE_INSN and that would thus issue calls to __clear_cache with the default call expander, would fail on languages that did not set up the __clear_cache builtin. This patch arranges for all languages to set up this builtin. Machines or multilibs that had ptr_mode != Pmode, such as aarch64 with -mabi=ilp32, would fail the RTL mode test of the arguments passed to __clear_cache, because we'd insist on ptr_mode. This patch arranges for Pmode to be accepted as well. for gcc/ChangeLog * tree.c (build_common_builtin_nodes): Declare __builtin___clear_cache for all languages. * builtins.c (maybe_emit_call_builtin___clear_cache): Accept Pmode arguments.
