    • 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.

    • Eradicate MQ some more · 0b390d60 
      Nothing uses MQ anymore, but it still shows up in all the dump files.
This patch removes it from CALL_REALLY_USED_REGISTERS so that that does
not happen anymore (it is still a fixed register, there should be no
functional change).


	* config/rs6000/rs6000.h (CALL_REALLY_USED_REGISTERS): Do not
	include MQ.

    • Add validation and consolidation of fix-it hints · ee908516 
      The first aspect of this patch is to add some checking of fix-it hints.
The idea is to put this checking within the rich_location machinery,
rather than requiring every diagnostic to implement it for itself.

The fixits within a rich_location are "atomic": all must be valid for
any to be applicable.

We reject any fixits involving locations above
LINE_MAP_MAX_LOCATION_WITH_COLS.

There's no guarantee that it's sane to modify a macro, so we reject
any fix-its that touch them.

For example, note the attempt to provide a fix-it for the definition
of the macro FIELD:

spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
 #define FIELD colour
               ^
               color
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
   return ptr->FIELD;
               ^~~~~

After this patch, the fixit is not displayed:

spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
 #define FIELD colour
               ^
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
   return ptr->FIELD;
               ^~~~~

We might want some way for a diagnostic to opt-in to fix-its that
affect macros, but for now it's simplest to reject them.

The other aspect of this patch is fix-it consolidation: in some cases
neighboring fix-its can be merged.  For example, in a diagnostic to
modernize old-style struct initializers from:

 struct s example = {
- foo: 1,
+ .foo = 1,
 };

one approach would be to replace the "foo" with ".foo" and the ":"
with " =".  This would give two "replace" fix-its:

  foo: 1,
  --- FIXIT 1
  .foo
     - FIXIT 2
     =

This patch allows them to be consolidated into a single "replace" fix-it:

  foo: 1,
  ----
  .foo =

    • Tweak to colors of fix-it hints · d41e76cf 
      Previous, fix-it hints were printed using the color of the severity
of the diagnostic (magenta for warnings, red for errors, cyan for
notes).

This patch updates fix-it hints so that replacement text is printed in
green, to better distinguish the suggested improvement from
the current code.  For example:

spellcheck-fields.cc:52:13: error: 'struct s' has no member named 'colour'; did you mean 'color'?
   return ptr->colour;  <<< RED
               ^~~~~~   <<< RED
               color    <<< GREEN

It makes sense for the underlinings that indicate deletions to
be printed in red, so the patch changes that also.  For example:

diagnostic-test-show-locus-color.c:179:9: warning: example of a removal hint
   int a;;  <<< MAGENTA
         ^  <<< MAGENTA
         -  <<< RED

gcc/ChangeLog:
	* diagnostic-color.c (color_dict): Add "fixit-insert" and
	"fixit-delete".
	(parse_gcc_colors): Update description of default GCC_COLORS.
	* diagnostic-show-locus.c (colorizer::set_fixit_hint): Delete.
	(colorizer::set_fixit_insert): New method.
	(colorizer::set_fixit_delete): New method.
	(colorizer::get_color_by_name): New method.
	(colorizer::STATE_FIXIT_INSERT): New constant.
	(colorizer::STATE_FIXIT_DELETE): New constant.
	(class colorizer): Drop "_cs" suffix from fields.  Delete "_ce"
	fields in favor of new field "m_stop_color".  Add fields
	"m_fixit_insert" and "m_fixit_delete".
	(colorizer::colorizer): Update for above changes.  Replace
	colorize_start calls with calls to get_color_by_name.
	(colorizer::begin_state): Handle STATE_FIXIT_INSERT and
	STATE_FIXIT_DELETE.  Update for field renamings.
	(colorizer::finish_state): Simplify by using m_stop_color,
	rather than multiple identical "*_ce" fields.
	(colorizer::get_color_by_name): New method.
	(layout::print_any_fixits): Print insertions and replacements
	using the "fixit-insert" color, and deletions using the
	"fixit-delete" color.
	* doc/invoke.texi (-fdiagnostics-color): Update description of
	default GCC_COLORS, and of the supported capabilities.

gcc/testsuite/ChangeLog:
	* gcc.dg/plugin/diagnostic-test-show-locus-color.c
	(test_fixit_insert): Update expected output.
	(test_fixit_remove): Likewise.
	(test_fixit_replace): Likewise.
