    • C++: more location wrapper nodes (PR c++/43064, PR c++/43486) · dfd7fdca 
      This is v6 of the patch, as posted to:
  https://gcc.gnu.org/ml/gcc-patches/2018-12/msg01331.html


The C++ frontend gained various location wrapper nodes in r256448 (GCC 8).
That patch:
  https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00799.html
added wrapper nodes around all nodes with !CAN_HAVE_LOCATION_P for:

* arguments at callsites, and for

* typeid, alignof, sizeof, and offsetof.

This is a followup to that patch, adding many more location wrappers
to the C++ frontend.  It adds location wrappers for nodes with
!CAN_HAVE_LOCATION_P to:

* all literal nodes (in cp_parser_primary_expression)

* all id-expression nodes (in finish_id_expression), except within a
  decltype.

* all mem-initializer nodes within a mem-initializer-list
  (in cp_parser_mem_initializer)

However, the patch also adds some suppressions: regions in the parser
for which wrapper nodes will not be created:

* within a template-parameter-list or template-argument-list (in
  cp_parser_template_parameter_list and cp_parser_template_argument_list
  respectively), to avoid encoding the spelling location of the nodes
  in types.  For example, "array<10>" and "array<10>" are the same type,
  despite the fact that the two different "10" tokens are spelled in
  different locations in the source.

* within a gnu-style attribute (none of are handlers are set up to cope
  with location wrappers yet)

* within various OpenMP clauses

The patch enables various improvements to locations for bad
initializations, for -Wchar-subscripts, and enables various other
improvements in the followup patch.

For example, given the followup buggy mem-initializer:

class X {
  X() : bad(42),
        good(42)
  { }
  void* bad;
  int good;
};

previously, our diagnostic was on the final close parenthesis of the
mem-initializer-list, leaving it unclear where the problem is:

t.cc: In constructor 'X::X()':
t.cc:3:16: error: invalid conversion from 'int' to 'void*' [-fpermissive]
    3 |         good(42)
      |                ^
      |                |
      |                int

whereas with the patch we highlight which expression is bogus:

t.cc: In constructor 'X::X()':
t.cc:2:13: error: invalid conversion from 'int' to 'void*' [-fpermissive]
    2 |   X() : bad(42),
      |             ^~
      |             |
      |             int

Similarly, the diagnostic for this bogus initialization:

i.cc:1:44: error: initializer-string for array of chars is too long [-fpermissive]
    1 | char test[3][4] = { "ok", "too long", "ok" };
      |                                            ^

is improved by the patch so that it indicates which string is too long:

i.cc:1:27: error: initializer-string for array of chars is too long [-fpermissive]
    1 | char test[3][4] = { "ok", "too long", "ok" };
      |                           ^~~~~~~~~~
