* cpplib.h (TTYPE_TABLE): Rearrange to use only two per-entry
macros, not five.
* cpphash.h (TOKEN_NAME): New macro.
(_cpp_spell_operator): Deleted.
(token_spellings): Now _cpp_token_spellings.
* cppexp.c: Use TOKEN_NAME or TYPE_NAME, not _cpp_spell_operator.
* cpplex.c: Use OP and TK macros when expanding the
TTYPE_TABLE. Eliminate token_names. For non-OPERATOR tokens,
store the stringification of the enumeration name (CPP_CHAR,
etc.) in the name slot of token_spellings.
Use TOKEN_NAME and/or TOKEN_SPELL, do not reference
token_spellings directly.
* cpplib.c: Use TOKEN_SPELL.
* cpplex.c (_cpp_push_token): If the token being pushed back
is the previous token in this context, just subtract one from
context->posn.
* cppmacro.c (save_expansion): Clear aux field when storing a
placemarker.
* gcc.dg/cpp/paste5.c: New test.
* gcc.dg/cpp/vararg1.c: New test.

/* Regression test for bug in convoluted situation involving token paste
|
|
plus function-like macros used outside function context. It may be
|
|
easier to understand if you mentally replace 'struct' with 'A'
|
|
throughout this file; 'struct' is used only to get the code to compile
|
|
when preprocessed correctly.
|
|
|
|
The original problem was seen in the Linux kernel and reported by
|
|
Jakub Jelinek <jakub@redhat.com>; this test is synthetic. */
