| | 3 | Miscellaneous %define and %code cleanup. |
| | 4 | * data/bison.m4 (b4_percent_define_flag_if): Correct comments on how |
| | 5 | values are interpreted. |
| | 6 | * doc/bison.texinfo (Decl Summary): Clean up and extend %define |
| | 7 | documentation a little more. |
| | 8 | * src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT, |
| | 9 | muscle_percent_define_insert, muscle_percent_code_grow): New |
| | 10 | functions/macros. |
| | 11 | * src/muscle_tab.h (muscle_percent_define_insert, |
| | 12 | muscle_percent_code_grow): Prototype. |
| | 13 | * src/parse-gram.y (prologue_declaration): Use |
| | 14 | muscle_percent_define_insert and muscle_percent_code_grow when parsing |
| | 15 | %define and %code directives. |
| | 16 | |
| | 17 | Make it easy to share %define boolean variables between the front-end |
| | 18 | and back-end. Though not used yet, this will be useful in the future. |
| | 19 | * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about |
| | 20 | Bison uses of names rather than just skeleton uses of names. |
| | 21 | (b4_percent_define_get, b4_percent_define_ifdef): Rename |
| | 22 | b4_percent_define_skeleton_variables(VARIABLE) to |
| | 23 | b4_percent_define_bison_variables(VARIABLE). |
| | 24 | (b4_percent_code_get, b4_percent_code_ifdef): Rename |
| | 25 | b4_percent_code_skeleton_qualifiers(QUALIFIER) to |
| | 26 | b4_percent_code_bison_qualifiers(QUALIFIER). |
| | 27 | (b4_check_user_names_wrap): Update for renames. |
| | 28 | * src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if, |
| | 29 | muscle_percent_define_default): New functions mimicking |
| | 30 | b4_percent_define_flag_if and b4_percent_define_default. |
| | 31 | |
| | 32 | For %define variables, report locations for invalid values and |
| | 33 | redefinitions. |
| | 34 | * data/bison.m4 (b4_percent_define_flag_if): Read |
| | 35 | b4_percent_define_loc(VARIABLE) to report the location of an invalid |
| | 36 | value for VARIABLE. |
| | 37 | (b4_percent_define_default): Save a special location in |
| | 38 | b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE |
| | 39 | must later be reported as invalid. |
| | 40 | * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New |
| | 41 | functions. |
| | 42 | (muscle_percent_define_insert): Record the location of VARIABLE in |
| | 43 | muscle percent_define_loc(VARIABLE), and use it to report the previous |
| | 44 | location for a redefinition. |
| | 45 | (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if. |
| | 46 | (muscle_percent_define_default): Update like b4_percent_define_default. |
| | 47 | (muscle_grow_user_name_list): Rename to... |
| | 48 | (muscle_user_name_list_grow): ... this for consistency and use |
| | 49 | muscle_location_grow. |
| | 50 | * src/muscle_tab.h (muscle_location_grow): Prototype. |
| | 51 | * tests/input.at (%define errors): Update expected output. |
| | 52 | * tests/skeletons.at (%define boolean variables: invalid skeleton |
| | 53 | defaults): New test case. |
| | 54 | |
| | 55 | 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu> |
| | 56 | |
| | 57 | * src/print.c (lookahead_set, state_default_rule): Remove. |
| | 58 | (print_reductions): Replace state_default_rule invocation with |
| | 59 | equivalent use of yydefact, which was computed in token_actions in |
| | 60 | tables.c. |
| | 61 | (print_results): Don't allocate lookahead_set. |
| | 62 | |
| | 63 | 2007-02-27 Paolo Bonzini <bonzini@gnu.org> |
| | 64 | |
| | 65 | * data/lalr1.java: Prefix all private members with yy. |
| | 66 | |
| | 67 | 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu> |
| | 68 | |
| | 69 | Use YYFPRINTF instead of fprintf where appropriate. Reported by |
