    • rs6000: Don't emit a use of LR in returns and sibcalls · dd9fe1b9 
      The exit block (to which every return artificially jumps) already has
a use of LR.  The LR use in all returns and sibcalls is an anachronism,
probably made unnecessary by the dataflow merge.  The simple_returns
that shrink-wrapping generates also do not have such a use.  Newer
backends do not do this either it seems.

With this use removed, a normal return is no longer a parallel but just
a return insn, and cfgcleanup then can transform conditional jumps to
those into conditional returns.

This splits the return emission code with restoring_FPRs_inline from
that without it; this is simpler code, fewer lines, and less indentation.

The return_internal_<mode> pattern can now be deleted since nothing uses
it anymore.


	* config/rs6000/rs6000.c (rs6000_emit_epilogue): Do not emit
	USEs of LR_REGNO in returns and sibcalls.
	(rs6000_output_mi_thunk): Similar.

	Remove the USE of LR_REGNO from the patterns as well.  Delete an
	obsolete comment.
	(return_internal_<mode>): Delete.

    • rich_location: add convenience overloads for adding fix-it hints · f9087798 
      Adding a fix-it hint to a diagnostic usually follows one of these
patterns:
(a) an insertion fix-its, with the insertion at the primary caret location
(b) a removals/replacements, affecting the range of the primary location

(other cases are possible, e.g. multiple fix-its, and affecting other
locations, but these are the common ones)

Given these common cases, this patch adds overloads of the rich_location
methods for adding fix-it hints, so that the location information can
be omitted if it matches that of the primary location within the
rich_location.

Similarly when adding "remove" and "replace" fix-it hints to a diagnostic,
it's tedious to have to extract the source_range from a location_t
(aka source_location).  To make this more convenient, this patch
adds overload of the rich_location::add_fixit_remove/replace methods,
accepting a source_location directly.

The patch updates the various in-tree users of fix-it hints to use
the new simpler API where appropriate.  I didn't touch the case where
there are multiple fix-its in one rich_location, as it seems better to
be more explicit about locations for this case (adding a pair of parens
in warn_logical_not_parentheses).

The above makes the gcc_rich_location::add_fixit_misspelled_id overload
taking a const char * rather redundant, so I eliminated it.

gcc/c/ChangeLog:
	* c-decl.c (implicit_decl_warning): Use add_fixit_replace
	rather than add_fixit_misspelled_id.
	(undeclared_variable): Likewise.
	* c-parser.c (c_parser_declaration_or_fndef): Likewise.  Remove
	now-redundant "here" params from add_fixit_insert method calls.
	(c_parser_parameter_declaration): Likewise.
	* c-typeck.c (build_component_ref): Remove now-redundant range
	param from add_fixit_replace method calls.

	* name-lookup.c (suggest_alternatives_for): Use add_fixit_replace
	rather than add_fixit_misspelled_id.
	* parser.c (cp_parser_diagnose_invalid_type_name): Likewise.

	(test_one_liner_fixit_replace_equal_secondary_range): Likewise.

    • compiler: add -fgo-c-header=FILE to create a C header · 2adb671d 
          
    The new -fgo-c-header=FILE option will write a C header file defining
    all the struct types and numeric const values in package scope.  This
    will be used when building the Go runtime package (libgo/go/runtime) to
    generate a C header file that may be included by the C code in the C
    runtime package (libgo/runtime).
    
    This will ensure that the Go code and C code are working with the same
    data structures as we convert the runtime from C to Go to upgrade to the
    current GC runtime, notably the concurrent garbage collector.
