- Authentication-results: sourceware.org; auth=none
- References: <1395463432-29750-1-git-send-email-sergiodj at redhat dot com>
Patch for the Fortran language. This patch is similiar to the C
language one.
2014-03-22 Sergio Durigan Junior <sergiodj@redhat.com>
* f-exp.y (parse_type, parse_f_type): Rewrite macros to use
parser state.
(yyparse): Redefine macro to f_parse_internal.
(pstate): New variable.
(parse_number): Add "struct parser_state" argument.
(type_exp, exp, subrange, typebase): Update calls to write_exp*
and similars in order to use parser state.
(parse_number): Adjust code to use parser state.
(yylex): Likewise.
(f_parse): New function.
* f-lang.h: Forward declare "struct parser_state".
(f_parse): Add "struct parser_state" argument.
