This is the same issue as PR86429, just in potential_constant_expression_1 rather than cxx_eval_constant_expression. As in that case, when we're trying to evaluate a constant expression within a lambda, we don't have a constant closure object to refer to, but we can try to refer directly to the captured variable. gcc/cp/ChangeLog 2020-05-05 Jason Merrill <jason@redhat.com> PR c++/90212 * constexpr.c (potential_constant_expression_1): In a lambda function, consider a captured variable directly.

For default member initializers in templates it's important to push into the right context during get_nsdmi. But for a local class that's not possible, and trying leaves the function context we need to be in, so don't try. gcc/cp/ChangeLog 2020-05-01 Jason Merrill <jason@redhat.com> PR c++/90479 * init.c (get_nsdmi): Don't push_to_top_level for a local class.

cp_finish_decl avoids setting TREE_READONLY on TREE_STATIC variables that have non-constant construction or destruction, but -fmerge-all-constants was converting an automatic variable to static while leaving TREE_READONLY set. Fixed by clearing the flag in cp_finish_decl in the presence of -fmerge-all-constants. gcc/cp/ChangeLog 2020-05-01 Jason Merrill <jason@redhat.com> PR c++/91529 * decl.c (cp_finish_decl): Also clear TREE_READONLY if -fmerge-all-constants.

Within the generic lambda the VLA capture proxy VAR_DECL has DECL_VALUE_EXPR which is a NOP_EXPR to the VLA type of the proxy. The problem here was that when instantiating we were tsubsting that type twice, once for the type of the DECL and once for the type of the NOP_EXPR, and getting two different (though equivalent) types. Then gimplify_type_sizes fixed up the type of the DECL, but that didn't affect the type of the NOP_EXPR, leading to sadness. Fixed by directly reusing the type from the DECL. gcc/cp/ChangeLog 2020-05-01 Jason Merrill <jason@redhat.com> PR c++/93822 * pt.c (tsubst_decl): Make sure DECL_VALUE_EXPR continues to have the same type as the variable.

Another case where we need a linker-visible symbol in order to preserve the ld64 atom model. If these symbols are emitted as 'local' the linker cannot see that they are separate from any global weak entry that precedes them. This will cause the linker to complain that there is (apparently) direct access to such a weak global. This is a short-term fix for the problem - ideally we need a more generic handling for all the relevant cases. Backport 804254ed gcc/ChangeLog: * config/darwin.h (ASM_GENERATE_INTERNAL_LABEL): Make ubsan_{data,type},ASAN linker-visible.

This is a case where the standard contains conflicting information. after discussion between implementators, the accepted intent is of [class.copy.elision].

These functions were originally static members of the path class, but the 'static' specifiers were not removed when they were moved to namespace scope. This causes ODR violations when the functions are called from functions defined in the header. Change them to 'inline' instead.

Checking whether a filesystem::path constructor argument is an iterator requires instantiating std::iterator_traits. In C++20 that checks for satisfaction of std::iterator_traits constraints, which checks if the type is copyable, which can end up recursing back to the path constructor. The fix in LWG 3420 is to reorder the cpp17-iterator concept's constraints to check if the type looks vaguely like an iterator before checking copyable. That avoids the recursion for types which definitely aren't iterators, but isn't foolproof. Backport from mainline 2020-05-21 Jonathan Wakely <jwakely@redhat.com> PR libstdc++/93983 * include/bits/iterator_concepts.h (__detail::__cpp17_iterator): Reorder constraints to avoid recursion when constructors use iterator_traits (LWG 3420). * testsuite/24_iterators/customization_points/lwg3420.cc: New test.

We're getting an error when running this test on PowerPC VxWorks 7, due to an unexpected warning: | Excess errors: | cc1: warning: '-mvsx' and '-mno-altivec' are incompatible The warning comes from a combination of factors: - The test itself uses -mvsx explicitly via the following directive: // { dg-options "-O1 -mvsx" } - Our toolchain was configured so as to make -mno-altivec the default; - These two options are mutually exclusive. This commit adds a powerpc_vsx_ok dg-require-effective-target directive to that test, and thus making it UNSUPPORTED instead. Tested on PowerPC VxWorks 7. Also tested on PowerPC ELF as well, a platform where we do not make -mno-altivec the default, to verify that the test continues to run as usual in that case. gcc/testsuite/ * gcc.target/powerpc/pr71763.c: Require powerpc_vsx_ok.

Both array concat and array new expressions wrapped any temporaries created into a BIND_EXPR. This does not work if an expression used to construct the result requires scope destruction, which is represented by a TARGET_EXPR with a clean-up, and a CLEANUP_POINT_EXPR at the location where the temporaries logically go out of scope. The reason for this not working is because the lowering of cleanup point expressions does not traverse inside BIND_EXPRs to expand any gimple cleanup expressions within. The use of creating BIND_EXPR has been removed at both locations, and replaced with a normal temporary variable that has initialization delayed until its address is taken. gcc/d/ChangeLog: PR d/94970 * d-codegen.cc (force_target_expr): Move create_temporary_var implementation inline here.
