    • Implement P1286R2, Contra CWG1778 · 0998d2fd
      The C++11 requirement that an explicit exception-specification on a
      defaulted function match the implicit one was found to be problematic for
      std::atomic.  This paper, adopted in February, simply removes that
      requirement: if an explicitly defaulted function has a different
      exception-specification, that now works just like a user-written function:
      either it isn't noexcept when it could be, or it is noexcept and will call
      terminate if an exception is thrown.
      
      	* method.c (defaulted_late_check): Don't check explicit

      This patch is the first part of library support for constexpr
      std::vector and std::string. This only includes the changes to
      std::allocator, std::allocator_traits, std::construct_at,
      std::destroy_at, std::destroy and std::destroy_n.
      
      std::allocator::allocate and std::allocator::deallocate need to be
      added so that they can be intercepted by the compiler during constant
      evaluation. Outside of constant evaluation those new member functions
      just forward to the existing implementation in the base class.

      These changes are largely useless, because most of them are simply
      allowing 'reference' and 'const_reference' types to be obtained from an

      just use plain lvalue references. Pretending to support C++98 allocators

    • Fix incorrect merge of conflictant names in `dump_graphviz` · 51940760
      When using lto-dump -callgraph with two or more .o files containing distinct
      functions with the same name, dump_graphviz incorrectly merged those functions
      into a single node. This patch fixes this issue by calling `dump_name` instead
      of `name`, therefore concat'ing the function name with the node's id.
      
      To understeand what was the issue, let's say you have two files:
      
      a.c: static void foo (void) { do_something (); }
      
      b.c: static void foo (void) { do_something_else (); }
      
      These are distinct functions and should be represented as distinct nodes in the
      callgraph dump.
