* ada-exp.y: Considerable reorganization to move functionality from ada-lex.l to here, where it is logically more appropriate. The original reason, however, was to prevent premature name lookups for selector names in record aggregates. (BLOCKNAME, TYPENAME, OBJECT_RENAMING): Remove; lexer now returns NAME for all of these. (VAR): New artificial token to clarify precedence rules. (OTHERS): New lexeme. (empty_stoken): New symbol. (%union): Remove ssym, voidval. (%type): Remove <voidval> type declarations. (syntax definitions): Add aggregates. Remove distinction between NAME, TYPENAME, BLOCKNAME, OBJECT_RENAMING. Rename some non-terminals to be closer to reference manual usage. Tighten up expression syntax to disallow certain non-Ada constructions such as X and then Y or else Z. (ada_parse): Remove initialization of left_block_context. (write_var_from_name): Remove. (write_var_or_type): New function, containing previous code from defunct write_var_from_name and name_lookup.

Return all NAMEs, BLOCKNAMEs, OBJECT_RENAMINGs, TYPENAMEs in yylval.sval (as simple strings). All name look-ups now handled in ada-exp.y. Introduce "::" (COLONCOLON) token and return as separate token. (processId): Change return convention. Comment. Leave leading "'" in place. (processString): New function. (find_dot_all): Add note to comment. Fix problem that allowed match only at the end. * ada-lang.c: Introduce aggregates.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered. Below you can see the message links from the discussions: - First attempt: <https://sourceware.org/ml/gdb-patches/2012-01/msg00522.html> Message-ID: <m3k44s7qej.fsf@gmail.com> - Second attempt: <https://sourceware.org/ml/gdb-patches/2012-06/msg00054.html> Message-Id: <1338665528-5932-1-git-send-email-sergiodj@redhat.com> - Third attempt: <https://sourceware.org/ml/gdb-patches/2014-01/msg00949.html> Message-Id: <1390629467-27139-1-git-send-email-sergiodj@redhat.com> - Fourth (last) attempt: <https://sourceware.org/ml/gdb-patches/2014-03/msg00546.html> Message-Id: <1395463432-29750-1-git-send-email-sergiodj@redhat.com> gdb/ 2014-03-27 Sergio Durigan Junior <sergiodj@redhat.com> Remove some globals from our parser. * language.c (unk_lang_parser): Add "struct parser_state" argument. * language.h (struct language_defn) <la_parser>: Likewise. * parse.c (expout, expout_size, expout_ptr): Remove variables.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

'.{WHITE}*all' component of a dotted name, or -1 if there is none.
Note: we actually don't need this routine, since 'all' can never be an
Ada identifier. Thus, looking up foo.all or foo.all.x as a name
must fail, and will eventually be interpreted as (foo).all or
(foo).all.x. However, this does avoid an extraneous lookup. */
