This fixes bug #31792.

(dbgtok,debugtoken): New diagnostic functions.
(tokdel,tokins): New functions.
(nexttoken): Clear yylval.str. Print token stack state.
(putback): Copy all data to tok. Print token stack state.
(file_error,restore
(is_function): Hanlde struct, union and enum: all these can
appear in the return type specification.
(fake_struct): Don't destroy token stack. Use tokdel and tokins
to modify it.
(parse_variable_declaration): Likewise.

* NEWS: Update.
* README: Update.
* doc/cflow.texi: Update.
* src/main.c (symbol_override): pass allocated argument to install.
* src/parser.c (yyparse): Return 0.
|
|
* src/parser.c (dcl): allow for qualifier wherever a modifier
is allowed.
|
|
|
|
* doc/cflow.texi: Document symbol classes and aliases.
* src/cflow.rc: Minor change.
* src/main.c: Mention aliasing feature in the docstring for --symbol.
|
|
|

The latter feature is useful for declaring reserved symbols such
as __restrict or __inline, e.g. --symbol __restrict:=restrict
instructs cflow to treat `__restrict' exactly as `restrict'.

init_lex.
Install qualifiers.

aliases to other tokens (--symbol __inline:=inline).
* src/parser.c (print_token): print qualifiers and ops.
(file_error): Change signature. All uses changed.
(save_token): Improve output spacing.
(skip_balanced): Treat LBRACE0 and RBRACE0 as { and }.
(is_function): allow for qualifiers and wrappers before
defintion.
(parse_function_declaration): Remove PARM_WRAPPER case: it
is taken care of by the caller.
(fake_struct): leave when '(' is encountered.
(parse_variable_declaration): Allow for qualifiers before
the identifier.
(skip_struct): Use skip_balanced.
(dcl): Handle wrappers. Leave if a semicolon is encountered.

* tests/nfparg.at: Change spacing to reflect changes to
save_token.
|
|

* src/parser.c (skip_balanced): Don't put extra token back.
* src/symbol.c (install): Take two arguments, the 2nd one
specifying whether the symbol can be local to the compilation
unit. All uses updated.
(delete_symbol): Don't delete symbol in reverse tree mode, if
its callee list is not empty.
|
|
* src/parser.c (save_token): Hanlde [ and ]. Do not enforce
space after ).
