From: Aleksandar Ristovski Date: Mon, 5 May 2008 14:37:32 +0000 (+0000) Subject: * ada-lang.c: Update throughout to use symbol_matches_domain X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5eeb2539423ce5e7241bce403f48b8babb3670b0;p=binutils-gdb.git * ada-lang.c: Update throughout to use symbol_matches_domain instead of matching the symbol domain explictly. * dwarf2read.c (add_partial_symbol): Do not add new psym for STRUCT_DOMAIN. Make sure you recognize c++ struct and java and ada class as typedefs. See lookup_partial_symbol function. (new_symbol): Similar to add_partial_symbol, do not create symbol for the typedef. See lookup_block_symbol. * symtab.c (symbol_matches_domain): New function, takes care of dual meaning of STRUCT_DOMAIN symbol for c++, ada and java. (lookup_partial_symbol): Use symbol_matches_domain to see if the found psym domain matches the given domain. (lookup_block_symbol): Likewise. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0302842cbc0..7474370a8f0 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,19 @@ +2008-05-05 Aleksandar Ristovski + Joel Brobecker + + * ada-lang.c: Update throughout to use symbol_matches_domain + instead of matching the symbol domain explictly. + * dwarf2read.c (add_partial_symbol): Do not add new psym for + STRUCT_DOMAIN.
