Denny + + Don't put the pre-prologue in the header file. For the yacc.c code + file and the glr.c header and code files, move the pre-prologue before + the token definitions. Add new %before-definitions and + %after-definitions to declare code that will go in both the header file + and code file. Discussed at + , + , + and + . + * NEWS (2.3+): Describe these changes. + * data/glr.c (b4_pre_prologue): Move from within to before... + (b4_shared_declarations): ... this. + Add new b4_before_definitions before b4_token_enums. + Add new b4_after_definitions at the end. + * data/glr.cc (b4_pre_prologue): Replace with... + (b4_before_definitions): ... this in the header file. + (b4_after_definitions): New near the end of the header file. + * data/lalr1.cc (b4_pre_prologue): Move from the header file to the + code file right before including the header file. + (b4_before_definitions): New in the previous position of + b4_pre_prologue in the header file. + (b4_after_definitions): New near the end of the header file. + * data/yacc.c: Clean up some m4 quoting especially in the header file. + (b4_token_enums_defines): In the code file, move to right before + YYSTYPE for consistency with the header file. + (b4_before_definitions): New right before b4_token_enums_defines in + both the header and code file. + (b4_after_definitions): New right after YYLTYPE and yylloc in both the + header and code file. + * doc/bison.texinfo (Prologue): Show use of %before-definitions instead + of prologues for %union dependencies. + (Bison Declaration Summary): In %defines description, mention the + effect of %before-definitions and %after-definitions on the header + file. + (Calc++ Parser): Forward declare driver in a %before-definitions rather + than in the pre-prologue so that make check succeeds. + (Bison Symbols): Add entries for %before-definitions and + %after-definitions. + * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for + %before-definitions. + (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions. + (declaration): Parse those declarations and append to + b4_before_definitions and b4_after_definitions, respectively. + * src/reader.c (before_definitions, after_definitions): New bools to + track whether those declarations have been seen. + (prologue_augment): Add to the post-prologue if %union, + %before-definitions, or %after-definitions has been seen. + * src/reader.h (before_definitions, after_definitions): New extern's. + * src/scan-gram.l: Scan the new declarations. + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second + prologue block in a %before-definitions or a %after-definitions based + on whether the %union is declared. + * tests/regression.at (Early token definitions with --yacc, Early token + definitions without --yacc): Move tests for token definitions into the + post-prologue since token names are no longer defined in the + pre-prologue. + +2006-06-20 Akim Demaille + + * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New. + (symbol_get): Use it. + * src/parse-gram.y: Use it. + +2006-06-19 Joel E.
