2022-11-04ada: Fix loop unnesting issue.Marc Poulhiès3-8/+16
During loop unnesting, when the loop statements are wrapped in a code block, the newly created block's scope must be set to the loop scope (instead of the previous 'Current_Scope' that would point to an upper scope). gcc/ada/ * sem_util.ads (Add_Block_Identifier): Add new extra Scope argument. * sem_util.adb (Add_Block_Identifier): Likewise and use this scope variable instead of Current_Scope. * exp_util.adb (Wrap_Statements_In_Block): Add new scope argument to Add_Block_Identifier call.
2022-11-04ada: Fix repeated killing of private entity valuesPiotr Trojanek1-29/+9
When killing known values of assignable entities we iterated from First_Entity and then again from First_Private_Entity. This second iteration was unnecessary, because the entity chain that starts with First_Entity contains all entities, including the private ones. This is just a performance improvement; the behavior is unchanged. gcc/ada/ * sem_util.adb (Kill_Current_Values): Only iterate from First_Entity through Next_Entity.
2022-11-04ada: Simplify detection of controlling formalsPiotr Trojanek1-3/+3

2022-11-04ada: Improve efficiency of scope stack restorationPiotr Trojanek1-2/+2
We save/restore visibility by setting the Is_Immediately_Visible flag and appending entities to / removing them from the tail of an element list. However, the Is_Immediately_Visible flag can be restored in any order, while the element list is singly-linked and removal from the tail is inefficient. This change removes a performance hot spot, which accounted for up to 10% of compilation time of complex applications (e.g. QGen), at least as measured on GNAT built with profiling support. gcc/ada/ * sem_ch8.adb (Restore_Scope_Stack): Remove elements from the head and not the tail of an element list.

2022-11-04ada: Allow enabling a restricted set of language extensions.Steve Baird22-95/+212
The -gnatX switch (and the related Extensions_Allowed pragma) is currently a two-valued all-or-nothing option. Add support for enabling a curated subset of language extensions without enabling others via the -gnatX switch and for enabling all language extensions via the new -gnatX0 switch. Similarly, the existing "ON" argument for the Extensions_Allowed pragma now only enables the curated subset; the new argument "ALL" enables all language extensions. The subset of language extensions currently includes prefixed-view notation with an untagged prefix, fixed-low-bound array subtypes, and casing on composite values. gcc/ada/ * opt.ads: Replace Ada_Version_Type enumeration literal Ada_With_Extensions with two literals, Ada_With_Core_Extensions and Ada_With_All_Extensions. Update uses of the deleted literal. Replace Extensions_Allowed function with two functions: All_Extensions_Allowed and Core_Extensions_Allowed. * errout.ads, errout.adb: Add Boolean parameter to Error_Msg_GNAT_Extension to indicate whether the construct in question belongs to the curated subset. * exp_ch5.adb, par-ch4.adb, sem_case.adb, sem_ch3.adb: * sem_ch4.adb, sem_ch5.adb, sem_ch8.adb: Replace calls to Extensions_Allowed with calls to Core_Extensions_Allowed for constructs that are in the curated subset. * sem_attr.adb, sem_ch13.adb, sem_eval.adb, sem_util.adb: Replace calls to Extensions_Allowed with calls to All_Extensions_Allowed for constructs that are not in the curated subset. * par-ch3.adb: Override default for new parameter in calls to Error_Msg_GNAT_Extension for constructs in the curated subset. * par-prag.adb: Add Boolean parameter to Check_Arg_Is_On_Or_Off to also allow ALL. Set Opt.Ada_Version appropriately for ALL or ON arguments. * sem_prag.adb: Allowed ALL argument for an Extensions_Allowed pragma. Set Opt.Ada_Version appropriately for ALL or ON arguments. * switch-c.adb: The -gnatX switch now enables only the curated subset of language extensions (formerly it enabled all of them); the new -gnatX0 switch enables all of them. * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Document new "-gnatX0" switch and update documentation for "-gnatX" switch. * doc/gnat_rm/implementation_defined_pragmas.rst: Document new ALL argument for pragma Extensions_Allowed and update documentation for the ON argument.

2022-11-04ada: Generate missing object decls for adainit/adafinal registration callsSteve Baird1-5/+14
A previous change on this ticket introduced calls to CUDA_Register_Function for adainit and adafinal, but failed to introduce declarations for the C string variables that are initialized and then passed as actual parameters in this call. Provide the missing declarations (and, incidentally, change the names of the two variables). gcc/ada/ * bindgen.adb: Introduce two new string constants for the names of the C-String variables that are assigned the names for adainit and adafinal. Replace string literals in Gen_CUDA_Init with references to these constants. In Gen_CUDA_Defs, generate C-String variable declarations where these constants are the names of the variables.
2022-11-04ada: Support lock-free protected objects with pragma Initialize_ScalarsPiotr Trojanek1-0/+9
In general, protected subprograms are only eligible for a lock-free expansion if they do not reference global assignable objects. However, it seems reasonable to ignore references to variables in System.Scalar_Values, which are generated when pragma Initialize_Scalars is active. Such references appear, for example, when protected subprogram has formal parameters of mode out. gcc/ada/ * sem_ch9.adb (Satisfies_Lock_Free_Requirements): Ignore references to global variables inserted due to pragma Initialize_Scalars.
2022-11-04ada: Remove VxWorks 6 and VxWorks 653 2.x content from the UGXCedric Landet3-6/+6

2022-11-04ada: Reject expanded global names in lock-free protected objectsPiotr Trojanek1-2/+2
Lock-free expansion of protected subprograms is only possible when there are no references to global assignable objects. We only detected such references when they appeared as direct names, but we must similarly detect expanded names. gcc/ada/ * sem_ch9.adb (Satisfies_Lock_Free_Requirements): Detect references via expanded names.
2022-11-04ada: Generate host-side CUDA_Register_Function calls for device's ↵Steve Baird1-17/+49
adainit/adafinal To invoke a device-side subprogram from the host (via a CUDA_execute pragma), the subprogram also has to be registered by calling CUDA_Register_Function. The host-side adainit and adafinal procedures need to invoke the corresponding device-side procedures, so corresponding CUDA_Register_Function calls need to be generated. gcc/ada/ * bindgen.adb (Gen_CUDA_Init): Move existing loop body into a new local procedure, Gen_CUDA_Register_Function_Call, and replace that loop body with a call to this procedure. This first part is just semantics-preserving refactoring. The second part is to add Gen_CUDA_Register_Function_Call calls after the loop for the device-side adainit and adafinal procedures.

2022-11-04Restore default 'sorry' 'TARGET_ASM_CONSTRUCTOR', 'TARGET_ASM_DESTRUCTOR'Thomas Schwinge5-0/+74
... that got lost in commit 7e0db0cdf01e9c885a29cb37415f5bc00d90c029 "STABS: remove -gstabs and -gxcoff functionality". Previously, if a back end was not 'USE_COLLECT2', nor manually defined 'TARGET_ASM_CONSTRUCTOR', 'TARGET_ASM_DESTRUCTOR', or got pointed to the respective 'default_[...]' functions due to 'CTORS_SECTION_ASM_OP', 'DTORS_SECTION_ASM_OP', or 'TARGET_ASM_NAMED_SECTION', it got pointed to 'default_stabs_asm_out_constructor', 'default_stabs_asm_out_destructor'. These would emit 'sorry' for any global constructor/destructor they're run into. This is now gone, and thus in such a back end configuration case 'TARGET_ASM_CONSTRUCTOR', 'TARGET_ASM_DESTRUCTOR' don't get defined anymore, and thus the subsequently following: #if !defined(TARGET_HAVE_CTORS_DTORS) # if defined(TARGET_ASM_CONSTRUCTOR) && defined(TARGET_ASM_DESTRUCTOR) # define TARGET_HAVE_CTORS_DTORS true # endif #endif ... doesn't define 'TARGET_HAVE_CTORS_DTORS' anymore, and thus per my understanding, 'gcc/final.cc:rest_of_handle_final': if (DECL_STATIC_CONSTRUCTOR (current_function_decl) && targetm.have_ctors_dtors) targetm.asm_out.constructor (XEXP (DECL_RTL (current_function_decl), 0), decl_init_priority_lookup (current_function_decl)); if (DECL_STATIC_DESTRUCTOR (current_function_decl) && targetm.have_ctors_dtors) targetm.asm_out.destructor (XEXP (DECL_RTL (current_function_decl), 0), decl_fini_priority_lookup (current_function_decl)); ... simply does nothing anymore for a 'DECL_STATIC_CONSTRUCTOR', 'DECL_STATIC_DESTRUCTOR'. This, effectively, means that GCC/nvptx now suddenly appears to "support" global constructors/destructors, which means that a ton of test cases now erroneously PASS that previously used to FAIL: sorry, unimplemented: global constructors not supported on this target Of course, such support didn't magically happen due to "STABS: remove -gstabs and -gxcoff functionality", so this is bad. And, corresponding execution testing then regularly FAILs (due to the global constructor/destructor functions never being invoked), for example: [-UNSUPPORTED:-]{+PASS:+} gcc.dg/initpri1.c {+(test for excess errors)+} {+FAIL: gcc.dg/initpri1.c execution test+} [-UNSUPPORTED:-]{+PASS:+} g++.dg/special/conpr-1.C {+(test for excess errors)+} {+FAIL: g++.dg/special/conpr-1.C execution test+} To restore the previous GCC/nvptx behavior, for traceability, this simply restores the previous code, stripped down to the bare minimum. gcc/ * Makefile.in (OBJS): Add 'dbxout.o'. * config/nvptx/nvptx.cc: '#include "dbxout.h"'. * dbxout.cc: New. * dbxout.h: Likewise. * target-def.h (TARGET_ASM_CONSTRUCTOR, TARGET_ASM_DESTRUCTOR): Default to 'default_stabs_asm_out_constructor', 'default_stabs_asm_out_destructor'.

2022-11-03c++: Quash -Wdangling-reference for member operator* [PR107488]Marek Polacek2-1/+33
-Wdangling-reference complains here: std::vector<int> v = ...; std::vector<int>::const_iterator it = v.begin(); while (it != v.end()) { const int &r = *it++; // warning } because it sees a call to __gnu_cxx::__normal_iterator<const int*, std::vector<int> >::operator* which returns a reference and its argument is a TARGET_EXPR representing the result of __gnu_cxx::__normal_iterator<const int*, std::vector<int> >::operator++ But 'r' above refers to one of the int elements of the vector 'v', not to a temporary object. Therefore the warning is a false positive. I suppose code like the above is relatively common (the warning broke cppunit-1.15.1 and a few other projects), so presumably it makes sense to suppress the warning when it comes to member operator*. In this case it's defined as reference operator*() const _GLIBCXX_NOEXCEPT { return *_M_current; } and I'm guessing a lot of member operator* are like that, at least when it comes to iterators. I've looked at _Fwd_list_iterator, _Fwd_list_const_iterator, __shared_ptr_access, _Deque_iterator, istream_iterator, etc, and they're all like that, so adding #pragmas would be quite tedious. :/ PR c++/107488 gcc/cp/ChangeLog: * call.cc (do_warn_dangling_reference): Quash -Wdangling-reference for member operator*. gcc/testsuite/ChangeLog: * g++.dg/warn/Wdangling-reference5.C: New test.
2022-11-03c++: requires-expr and access checking [PR107179]Patrick Palka2-0/+18
Like during satisfaction, we also need to avoid deferring access checks during substitution of a requires-expr because the outcome of an access check can determine the value of the requires-expr. Otherwise (in deferred access checking contexts such as within a base-clause), the requires-expr may evaluate to the wrong result, and along the way a failed access check may leak out from it into a non-SFINAE context and cause a hard error (as in the below testcase).

2022-11-03c++: constexpr error with defaulted virtual dtor [PR93413]Patrick Palka2-8/+10
We're rejecting the below testcase with error: 'virtual constexpr Base::~Base()' used before its definition error: 'virtual constexpr Derived::~Derived()' used before its definition due to special handling in mark_used added by r181272 to defer synthesis of virtual destructors until EOF (where we can set their linkage), which in turn makes them effectively unusable during constexpr evaluation. Fortunately it seems this special handling is unnecessary ever since r208030 enabled us to tentatively set linkage of all defaulted virtual destructors, including templated ones. So this patch gets rid of this special handling.
