This corresponds to the fixes done for std::any_cast, but has to be done without if-constexpr. The dummy specialization of _Manager_internal<_Op> is used to avoid instantiating the real _Manager_internal<T>::_S_manage function just to compare its address. PR libstdc++/90220 * include/experimental/any (__any_caster): Constrain to only be callable for object types. Use remove_cv_t instead of decay_t. If the type decays or isn't copy constructible, compare the manager function to a dummy specialization. (__any_caster): Add overload constrained for non-object types.

There was a regression for gfortran.dg/fmt_en.f90 for cris-elf that on inspection was due to it having acquired a truncation call through the runtime. I updated that and the new tests that had "Fortran runtime error: required ftruncate or chsize support not present" messages in gfortran.log, ran past cris-elf and committed as obvious. See also <https://gcc.gnu.org/ml/gcc-patches/2008-05/msg00975.html> from which I copy-pasted most of this message.

PR c++/90462 reports an ICE with -fdiagnostics-format=json when attempting to serialize a malformed location to JSON. The compound location_t in question has meaningful "caret" and "start" locations, but has UNKNOWN_LOCATION for its "finish" location, leading to a NULL pointer dereference when attempting to build a JSON string for the filename. This patch bulletproofs the JSON output so that attempts to write a JSON object for a location with a NULL file will lead to an object with no "file" key, and attempts to write a compound location with UNKNOWN_LOCATION for its start or finish will lead to the corresponding JSON child object being omitted. This patch also adds a json::object::get member function, for self-testing the above. gcc/ChangeLog: PR c++/90462 * diagnostic-format-json.cc: Include "selftest.h".

Remove the hardcoded whitelist of allocators expected to return memory aligned to alignof(max_align_t), because that doesn't work when the platform's malloc() and GCC's max_align_t do not agree what the largest fundamental alignment is. It's also sub-optimal for user-defined allocators that return memory suitable for any fundamental alignment. Instead use a hardcoded list of alignments that are definitely supported by the platform malloc, and use a copy of the allocator rebound to a POD type with the requested alignment. Only allocate an oversized buffer to use with std::align for alignments larger than any of the hardcoded values. For 32-bit Solaris x86 do not include alignof(max_align_t) in the hardcoded values.

get_frame_size () returns used stack slots during compilation, which may be optimized out later. This patch does the followings: 1. Add stack_frame_required to machine_function to indicate that the function needs a stack frame. 2. Change ix86_find_max_used_stack_alignment to set stack_frame_required. 3. Always call ix86_find_max_used_stack_alignment to check if stack frame is needed.

This patch adds support in the compiler for the architecture feature flags that binutils will use to enable/disable the new "Future Architecture Technologies" feature Scalable Vector Extension V2 (SVE2) announced at Linaro Connect this week. The "sve2" extension that enables the core sve2 instructions. This also enables the sve extension, since sve is a requirement of sve2. Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions. These are all given extra feature flags, "bitperm", "sve2-sm4", "sve2-aes", and "sve2-sha3" respectively. The sm4, aes, and sha3 extensions are explicitly marked as sve2 extensions to distinguish them from the corresponding NEON extensions. When introducing macros to denote these new features we have gone past what a 32 bit value can represent which means we need to change the type of those variables working with these feature flags to ensure they use 64 bit quantities. Tested with bootstrap on aarch64-none-linux-gnu and manually seeing that -march=armv8-a+typo prints out the expected flags while using the new feature flags does not complain about a missing flag (until reaching the assembler). gcc/ChangeLog: 2019-05-22 Matthew Malcomson <matthew.malcomson@arm.com> * common/config/aarch64/aarch64-common.c (struct aarch64_option_extension, struct processor_name_to_arch, struct arch_to_arch_name, aarch64_parse_extension, opt_ext_cmp, aarch64_contains_opt, aarch64_get_extension_string_for_isa_flags): Change type of variables storing flags to uint64_t. * config/aarch64/aarch64-option-extensions.def (sve2, sve2-sm4, sve2-aes, sve2-sha3, bitperm): New optional SVE2 extension flags. * config/aarch64/aarch64.c (struct processor, aarch64_parse_arch, aarch64_parse_cpu, aarch64_validate_mcpu, aarch64_validate_march, aarch64_override_options, aarch64_option_print, aarch64_handle_attr_isa_flags, aarch64_declare_function_name, aarch64_start_file): Make flag variables uint64_t. * config/aarch64/aarch64.h (AARCH64_FL_SVE2, AARCH64_FL_SVE2_AES, AARCH64_FL_SVE2_SM4, AARCH64_FL_SVE2_SHA3, AARCH64_FL_SVE2_BITPERM): New macro feature flags. * config/aarch64/aarch64.opt (aarch64_isa_flags): Make uint64_t. * config/aarch64/driver-aarch64.c (struct aarch64_arch_extension, struct aarch64_core_data, struct aarch64_arch_driver_info, host_detect_local_cpu): Make flag variables uint64_t. * doc/invoke.texi: Add documentation for new arguments.
