    • allow EH to escape from GIMPLE_EH_ELSE ELSE block · b847405a
      The only preexisting use of GIMPLE_EH_ELSE, for transactional memory
      commits, did not allow exceptions to escape from the ELSE path.  The
      trick it uses to allow the ELSE path to see the propagating exception
      does not work very well if the exception cleanup raises further
      exceptions: the ELSE block is configured to handle exceptions in
      itself.  This confuses the heck out of CFG and EH cleanups.
      
      Basing the lowering context for the ELSE block on outer_state, rather
      than this_state, gets us the expected enclosing handler.

      This defines the equivalent of C++2a's std::type_identity_t alias but
      for use in C++11 and later. This can be used to replace __detail::__idt
      in the string_view headers, which previously used common_type_t because

    • Relax vector_builder::elt sanity check · 72ab1c51
      I'd made it a precondition of vector_builder::elt that the encoding
      must have been fully populated and that all implicit elements are
      therefore defined.  But for one of the AArch64 patches I'm working on,
      it'd be convenient to be able to look back at previous elements while
      building up the encoding.  This patch therefore makes the assert
      specific to implicit elements only.

    • Support multiple operand counts for .md @ patterns · d281492d
      This patch extends the support for "@..." pattern names so that
      the patterns can have different numbers of operands.  This allows
      things like binary and ternary operations to be handled in a
      consistent way, a bit like optabs.  The generators assert that
      the number of operands passed is correct for the underlying
      instruction.
      
      Also, replace_operands_with_dups iterated over the old rtx format
      even after having decided to do a replacement, which broke with
      match_operator.

    • compiler: ensure evaluation order in type hash/eq functions · a8b9ee6f
          
          The type hash and equality functions are generated after the
          order_evaluations pass. They may contain shortcut operators and
          Set_and_use_temporary_expressions (e.g. from lowering a
          Binary_exprssion) that need to be ordered. Run order_evaluations
          and remove_shortcuts on these functions. (The hash functions
          may be fine, but to be on the safe side we run on them anyway.
          We do need to run on the equality functions.)
          
          A Set_and_use_temporary_expression is effectively an assignment,
          so it needs to be ordered. Otherwise if we insert a temporary
          statement before it, we may get wrong evaluation order.
          
          A test case is CL 185818.
          
          Fixes golang/go#33062.

    • [Ada] Refactor ownership pointer checking in SPARK as a generic · a8fa1b3d
      Ownership checking as done in SPARK should be applied only to SPARK
      code, which requires GNATprove knowledge of the SPARK_Mode boundary.
      Transform the checking unit into a generic to allow passing in the
      knowledge from GNATprove to that unit in GNAT sources.
      
      Keeping the code in GNAT sources makes it possible in the future to
      adapt it further (or simply instantiate it differently) to be used on
      Ada code, independently of GNATprove.
