From 53c5240fe15861d08db96684b1a06c4b4ecb1958 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Wed, 28 Mar 2007 00:12:15 +0000 Subject: [PATCH] * linespec.c: Include language.h. (find_methods): Add language parameter. Call lookup_symbol_in_language. Pass language down. (add_matching_methods): Likewise. Call lookup_symbol_in_language. (add_constructors): Likewise. (find_method): Pass sym_class to collect_methods. (collect_methods): Add sym_class parameter. Pass language down. * symtab.c (lookup_symbol): Rename to ... (lookup_symbol_in_language): ... this. Add language parameter. Use passed language instead of current_language. (lookup_symbol): New as wrapper around lookup_symbol_in_language. (lookup_symbol_aux): Add language parameter. Use passed language instead of current_language. (search_symbols): Indent. * symtab.h (enum language): Forward declare. (lookup_symbol_in_language): Declare. (lookup_symbol): Update description. * ada-lang.h (lookup_symbol_in_language): Remove declaration. * ada-lang.c (restore_language): Remove.
