    • Preserve original spellings of extended identifiers. · be5ffc59 
      This patch makes cpplib track the original spellings of extended
identifiers, as well as the canonical UTF-8 version, in order to
follow standard semantics properly without needing a convoluted and
undocumented canonicalization in translation phase 1 (see bug 9449
comments 39-46 regarding such a canonicalization).

The spelling is tracked in cpp_identifier and cpp_macro_arg without
making cpp_token any larger.  The original spelling is used for checks
of duplicate macro definitions, stringizing (see the C++ tests added;
this case is only an issue for C++ not C because C makes it
implementation-defined whether a \ is inserted before the \ of a UCN
in a string or character constant when stringizing, while C++ does
not), pasting (relevant when the result is then stringized for C++)
and when macro definitions are output as text (e.g. for -d options).

Once a macro has been defined, only the original spelling of the
argument names needs keeping in the argument list.  While it is being
defined, however, both spellings are needed: the original one for
subsequent saving for checks of duplicate macro definitions, and the
canonical one which is the node marked specially to generate macro
argument tokens rather than normal identifier tokens.  The buffer that
is used to save the original values of the identifier tokens is
changed so that it stores both those original values and a pointer to
the canonical hash nodes, so that those canonical nodes can be found
when their values need restoring after the macro definition has been
parsed.

I believe this covers the known standards issues in extended
identifiers support (the remaining unimplemented C99 areas in GCC all
being floating-point-related), except for C++ translation of extended
characters to UCNs in phase 1 (which I have no plans to work on).
There are however probably issues left with handling of extended
identifiers in other places, as listed in
<https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00337.html> (those
issues are generally the sort of thing that could be addressed as bugs
outside development stage 1).  (The bulk of the potential issues Zack
was concerned about in 2003-5, that resulted in extended identifiers
being disabled in the absence of -fextended-identifiers, were
effectively eliminated by the audit and fixes I did in 2009, however;
that todo list reflects what was left over after that audit.)

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.

    • Enable -fextended-identifiers by default. · 701cade1 
      As proposed at <https://gcc.gnu.org/ml/gcc/2014-11/msg00014.html>,
this patch enables -fextended-identifiers by default for all standard
versions including this feature (all C++ versions, C99 and above for
C, but not C90 / C94 / gnu89 / preprocessing assembler).  It adds a
couple of tests for areas where I previously noted testsuite coverage
for extended identifiers was lacking, removes -fextended-identifiers
from existing tests, adds -g to various such tests to verify that
extended identifiers don't break debug info generation and removes the
test that was only there to verify that the feature was off by
default.

The current state of the feature may not correspond exactly to any
particular checklist from 2004/5 (see bug 9449) of what was wanted
before enabling the feature by default, but I don't think it's any
worse than plenty of other features supported by default before every
corner case is fully functional, and think problems can readily be
fixed incrementally.

The following aspects of extended identifiers could still do with more
work (and should be straightforward):

* C -aux-info (output should use UCNs).

* ObjC -gen-decls (output should use UCNs; associated diagnostics from
  the ObjC front end should use extended characters or UCNs as
  appropriate to the locale, via using %qE or identifier_to_locale).

* Use DW_AT_use_UTF8 in DWARF-3 debug info for compilation units built
  with extended identifiers enabled (or unconditionally).

* cpplib diagnostics (outputting characters or UCNs as appropriate
  depending on the locale, as done for identifiers in non-cpplib
  diagnostics).

* C++ test for UCN linking with C and extern "C".

* Check GDB support / file issues for support if needed.

* Actual UTF-8 in identifiers (?).  (Be careful about not affecting
  performance for the normal fast path of lexing identifiers, if
  possible.)

The following may be trickier:

* cpplib spelling preservation (required to diagnose macro
  redefinition with different spellings of the same identifier in the
  definition or argument names; different spellings of the name of the
  macro itself are OK, however; also required for correct handling of
  multiple stringizing in C++); correct output for -d (UCNs), DWARF
  debug info for macros (UCNs), PCH and PCH tests.  (Spelling
  preservation is the issue that needs fixing to remove references to
  corner cases in the documentation of -std=c99 and -std=c11 and in
  c99status.html.)  The idea would be to add a second pointer to
  cpp_identifier that stores the original spelling (whether for
  extended identifiers only, or for all identifiers); this does not
  enlarge cpp_token because the resulting larger cpp_identifier
  structure is no bigger than cpp_string.

* C++ translation of extended characters (including $@` and various
  control characters) to UCNs in phase 1 (note diagnostics thus
  needed, but not for C++11, for control characters in strings /
  character constants as those UCNs invalid); a likely implementation
  approach is to do translation when identifiers / strings / character
  constants are lexed, together with errors for stray $@` / control
  characters in program as not being valid UCNs in identifiers ($ only
  if not accepted in identifiers); note that this translation should
  not take place inside raw string literals.

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.
