Add parens around constraint in <memory>. · e6c847fb

C++20 concepts require parens around atomic constraints that are not
primary-expressions.

	* include/std/memory (uses_allocator_construction_args): Add parens
	around constraint.

Simplify type-specifier parsing. · fd860f7d

Previously, the tentative parses for optional type-specifier and to support
class template argument deduction were combined awkwardly.  This
reorganization was motivated by the new concepts branch.

	* parser.c (cp_parser_simple_type_specifier): Separate tentative
	parses for optional type-spec and CTAD.

Fix g++.dg/template/pr84789.C on new concepts branch. · 19bd9028

On the concepts branch I ran into trouble where a pre-parsed dependent
nested-name-specifier got replaced on a subsequent parse with is_declaration
by one with typenames resolved, which was then used wrongly on a further
parse with !is_declaration.

    * parser.c (cp_parser_nested_name_specifier_opt): If the token is
    already CPP_NESTED_NAME_SPECIFIER, leave it alone.

[rs6000] Fix ambiguous .md attribute uses · f6e5e4b8

This patch is part of a series that fixes ambiguous attribute
uses in .md files, i.e. cases in which attributes didn't use
<ITER:ATTR> to specify an iterator, and in which <ATTR> could
have different values depending on the iterator chosen.

for formatting and line numbers.

runtime: expose the g variable · 4e62f891

    
    Currently, getg is implemented in C, which loads the thread-local
    g variable. The g variable is declared static in C.
    
    This CL exposes the g variable, so it can be accessed from the Go
    side. This allows the Go compiler to inline getg calls to direct
    access of g.
    
    Currently, the actual inlining is only implemented in the gollvm
    compiler. The g variable is thread-local and the compiler backend
    may choose to cache the TLS address in a register or on stack. If
    a thread switch happens the cache may become invalid. I don't
    know how to disable the TLS address cache in gccgo, therefore
    the inlining of getg is not implemented. In the future gccgo may
    gain this if we know how to do it safely.

[Darwin, testsuite] Remove unused test. · 61fba267

During GCC-9, the codegen for unreachable switch case statements changed
such that the (undefined) behaviour of reaching such statements is directed
to one of the existing switch cases.  This means that the testcase which
deals with the old behaviour can no longer work (and there is nothing to test
with it).  The [Darwin-specific] test is now redundant and can be removed.
