    • [Ada] Spurious warning on uninitialized entity during code generation · 0ffbef9f 
      This patch suppresses a spurious warning coming from the GCC backend, on
an aggregate that cannot be built in place and for which a temporary
variable must be created. If the type of the aggregate is a packed
boolean array, the generated code may appear to use an uninitialized
value for a component of the array, when in fact the code simply sets a
single bit of that array.

2018-10-09  Ed Schonberg  <schonberg@adacore.com>

gcc/ada/

	* exp_aggr.adb (Expand_Array_Aggregate): If it is not possible
	to build in place an aggregate with component associations, set
	the Warnings_Off flag on the generated temporary, to prevent
	spurious warnings from the backend when compiling with the
	-Wuninitialized gcc flag.

gcc/testsuite/

	* gnat.dg/warn18.adb: New testcase.

    • Define std::string and related typedefs outside __cxx11 namespace · 33b43b0d 
      The typedefs for common specializations of std::__cxx11::basic_string do
not need to be in the std::__cxx11 namespace. Those typedefs are never
used for linkage purposes so don't appear in mangled names, and so don't
need to be distinct from the equivalent typedefs for the COW
std::basic_string specializations. It is OK for the same typedef to
refer to different types in different translation units.

Defining them directly in namespace std improves diagnostics that use
those typedefs. For example:

error: could not convert '1' from 'int' to 'std::__cxx11::string' {aka 'std::__cxx11::basic_string<char>'}

will now be printed as:

error: could not convert '1' from 'int' to 'std::string' {aka 'std::__cxx11::basic_string<char>'}

The precise type is still shown, but the typedef is not obfuscated with
the inline namespace.

	* include/bits/stringfwd.h (string, wstring, u16string, u32string):
	Define typedefs outside of __cxx11 inline namespace.
	* python/libstdcxx/v6/printers.py (register_type_printers): Also
	register printers for typedefs in new location.
