Similar to the C++ case in the previous patch, but more involved as
the location of the pertinent token isn't readily available; the patch
adds it as a param to build_component_ref. All callers are updated to
provide the info, apart from objc_build_component_ref; fixing the latter
would lead to a cascade of other changes, so it's simplest to provide
UNKNOWN_LOCATION there and have build_component_ref fall back gracefully
for this case to the old behavior of showing a hint in the message,
without a fixit replacement in the source view.
This does slightly change the location of the error; before we had:
test.c:11:13: error: 'union u' has no member named 'colour'; did you mean 'color'?
return ptr->colour;
^~
with the patch we have:
test.c:11:15: error: 'union u' has no member named 'colour'; did you mean 'color'?
return ptr->colour;
^~~~~~
color
I think the location change is an improvement.
I don't know if I can argue that this is a bug fix, but it's a
user-visible improvement, low risk, and a (distantly-related) version
of it was posted in September:
https://gcc.gnu.org/ml/gcc-patches/2015-09/msg00747.html
Successfully bootstrapped®rtested on x86_64-pc-linux-gnu;
adds new 3 PASS results to gcc.sum.
OK for trunk in stage 3?
gcc/c/ChangeLog:
* c-parser.c (c_parser_postfix_expression): In __builtin_offsetof
and structure element reference, capture the location of the
element name token and pass it to build_component_ref.
(c_parser_postfix_expression_after_primary): Likewise for
structure element dereference.
(c_parser_omp_variable_list): Likewise for
OMP_CLAUSE_{_CACHE, MAP, FROM, TO},
* c-tree.h (build_component_ref): Add location_t param.
* c-typeck.c (build_component_ref): Add location_t param
COMPONENT_LOC. Use it, if available, when issuing hints about
mispelled member names to provide a fixit replacement hint.
gcc/objc/ChangeLog:
* objc-act.c (objc_build_component_ref): Update call
to build_component_ref for added param, passing UNKNOWN_LOCATION.
gcc/testsuite/ChangeLog:
* gcc.dg/spellcheck-fields-2.c: New test case.

The following patch adds a fix-it insertion hint for missing
"template <> " in explicit specializations.
This is more of an enhancement than a bug fix (PR 62314 is more of a
catch-all for adding fix-its), but it's low-risk and a user-visible
improvement, and this specific example is called out as a benefit
of clang over gcc in:
http://clang.llvm.org/diagnostics.html
I note that clang suggests inserting
template<>
whereas our diagnostic talks about
template <>
hence I have the fixit suggest inserting that. Should we change our
wording instead, and lose the space?
Successfully bootstrapped®rtested on x86_64-pc-linux-gnu;
adds 9 new PASS results to g++.sum.
OK for trunk in stage 3?

When we emit a hint about a misspelled member name, it will slightly
aid readability if we use a fixit-hint to show the proposed
name in context within the source code (and in the future this
might support some kind of auto-apply in an IDE).
This patch adds such a hint to the C++ frontend, taking us from:
test.cc:10:15: error: 'struct foo' has no member named 'colour'; did you mean 'color'?
return ptr->colour;
^~~~~~
to:
test.cc:10:15: error: 'struct foo' has no member named 'colour'; did you mean 'color'?

Looking over the discussion of missing semicolons in
"Quality of Implementation and Attention to Detail"
within
http://clang.llvm.org/diagnostics.html
and comparing with
https://gcc.gnu.org/wiki/ClangDiagnosticsComparison
I noticed that of the cases we do handle [1], there's room for
improvement; we currently emit:
test.c:2:11: error: expected ';' after struct definition
struct a {}
^
whereas clang reportedly emits:
test.c:2:12: error: expected ';' after struct
struct a {}
^
;
(note the offset of the location, and the fix-it hint)
The following patch gives us the latter, more readable output.
Arguably not a bug fix (PR 62314 is more of a catch-all
for adding fix-its), but it's low-risk and a user-visible
improvement.
Successfully bootstrapped®rtested on x86_64-pc-linux-gnu;
adds 15 new PASS results to g++.sum.
OK for trunk in stage 3?
[1] I've also filed PR c++/68970 about a case given on the clang
page that we still don't handle.

OK. What about field names in designated initializers (both C99-style and
old-style)?

* [PATCH 4/4] C: add fixit hint to misspelled field names
2016-04-28 14:04 [PATCH 1/4] PR c++/62314: add fixit hint for missing "template <> " in explicit specialization David Malcolm

Similar to the C++ case, but more involved as the location of the
pertinent token isn't readily available. The patch adds it as a param
to build_component_ref. All callers are updated to provide the info,
apart from objc_build_component_ref; fixing the latter would lead to
a cascade of other changes, so it's simplest to provide UNKNOWN_LOCATION
there and have build_component_ref fall back gracefully for this case
to the old behavior of showing a hint in the message, without a fixit
replacement in the source view.
This does slightly change the location of the error; before we had:
test.c:11:13: error: 'union u' has no member named 'colour'; did you mean 'color'?
return ptr->colour;
^~
with the patch we have:
test.c:11:15: error: 'union u' has no member named 'colour'; did you mean 'color'?
return ptr->colour;
^~~~~~
color
I think the location change is an improvement.
Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
OK for trunk?
gcc/c/ChangeLog:
* c-parser.c (c_parser_postfix_expression): In __builtin_offsetof
and structure element reference, capture the location of the
element name token and pass it to build_component_ref.
(c_parser_postfix_expression_after_primary): Likewise for
structure element dereference.
(c_parser_omp_variable_list): Likewise for
OMP_CLAUSE_{_CACHE, MAP, FROM, TO},
* c-tree.h (build_component_ref): Add location_t param.
* c-typeck.c (build_component_ref): Add location_t param
COMPONENT_LOC. Use it, if available, when issuing hints about
mispelled member names to provide a fixit replacement hint.
gcc/objc/ChangeLog:
* objc-act.c (objc_build_component_ref): Update call
to build_component_ref for added param, passing UNKNOWN_LOCATION.
gcc/testsuite/ChangeLog:
* gcc.dg/spellcheck-fields-2.c: New test case.
