Before AVX512F, processors with the newer ISAs also support the older ISAs, i.e., AVX2 processors also support AVX and SSE4, SSE4 processors also support SSSE3, ... After AVX512F, an AVX512XX processor may not support AVX512YY. It means AVX512XX features, except for AVX512F, can't be used to decide priority in target_clones. This patch updates error message for ISAs with P_ZERO priority. It also merges _feature_list into _isa_names_table and marks ISAs, which have unknown priority, with P_ZERO so that we only need to update one place to add a new ISA feature. gcc/ 2019-04-25 H.J.

Fix a problem with Function_declaration::import_function relating to how no-name or "sink" parameters are handled. In Gogo::start_function (for the non-inline case) when parameter bindings are being added, parameters with empty/sink names are renamed to synthesized "r.%d" / "p.%d" names so as to avoid collisions. This same handling needs to be present when creating the bindings for an inline function that's being instantiated after being read from export data. Fixes golang/go#31637.

The basic_string_view::pointer and basic_string_view::reference typedefs are supposed to refer to the non-const value type. In previous standards having traits_type::char_type different to value_type was simply undefined, but in the C++2a draft it's ill-formed, as changed by P1148R0. For std::basic_string and iostreams we might want to only enforce this conditionally for __cplusplus > 201703L but for std::basic_string_view we don't have backwards compatibility concerns. Also add assertions to verify the _CharT argument is a "char-like" type (non-array, trivial, standard layout type). Also remove the non-standard basic_string_view::_M_check and basic_string_view::_M_limit member functions, replacing them with non-member functions that will still exist even if basic_string_view is specialized by the program. * include/experimental/string_view (basic_string_view::pointer) (basic_string_view::reference): Fix to refer to non-const value_type. * include/bits/basic_string.h (basic_string): Use __sv_check and __sv_limit instead of basic_string_view::_M_check and basic_string_view::_M_limit. * include/std/string_view (__sv_check, __sv_limit): New helper functions to replace basic_string_view::_M_check and basic_string_view::_M_limit.

Although the std::any constructors use decay_t to determine the type of the contained value, std::any_cast should use the un-decayed type (and so always fail for function and array types that decay to pointers). Using remove_cv_t is correct, because the condition for std::any_cast to return non-null is operand.type() == typeid(T) and typeid ignores top-level cv-qualifiers. PR libstdc++/90220 * include/std/any (__any_caster): Use remove_cv_t instead of decay_t.

This patch fixes a cases where inconsistent CFI is generated. After restoring the hard frame pointer (r11) from an FPR we have to set the CFA register. In order to be able to set it back to the stack pointer (r15) we have to make sure that r15 has been restored already. The patch also adds a scheduler dependency to prevent the instruction scheduler from swapping the r11 and r15 restore again. gcc/ChangeLog: 2019-04-24 Andreas Krebbel <krebbel@linux.ibm.com> PR target/89952 * config/s390/s390.c (s390_restore_gprs_from_fprs): Restore GPRs from FPRs in reverse order.
