skeletons, and use this for %code qualifier complaints. * data/bison.m4 (b4_error_at): New, invoked by... (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap the skeleton scanner's new @warn_at(...@), @complain_at(...@), and @fatal_at(...@) directives. (b4_check_percent_code_qualifiers): Rewrite to expect locations for qualifiers in b4_used_percent_code_qualifiers and to use b4_complain_at. * src/location.c, src/location.h (boundary_set_from_string): New global function. * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global function. * src/parse-gram.y (grammar_declaration): Add locations for qualifiers to b4_used_percent_code_qualifiers. * src/scan-skel.l (fail_for_at_directive_too_few_args): New static function. (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments. (lineno): Rename to... (out_lineno): ... this so I don't misunderstand it again. (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines here; these newlines are in the input but not the output file. (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to... (at_directive_perform): ... this new static function, and add handling of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@) directives. * tests/input.at (Reject bad %code qualifiers): Update test output with locations and extend. * tests/output.at (Output file name: [, Output file name: ]): Remove bogus comment about these tests failing.
This directory contains the Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the file doc/FAQ for frequently asked questions. Bison requires GNU m4 1.4.3 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz Bison can work with pre-1.4.3 distributions of GNU m4 if they are sufficiently patched, but if you encounter a bug with an older distribution and report a bug we will probably suggest that you upgrade to 1.4.3 as the first step in trying to fix it. Please send bug reports to <bug-bison@gnu.org>. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005 Free Software Foundation, Inc.
