Re: [patch 2/3] Change cplus_specific to an alocated struct

[sami wagiaalla <swagiaal@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 132 bytes --]

This patch creates setters and getters for the newly named mangled_lang 
struct and changes all references to use these functions.


[-- Attachment #2: dynamic-cplus_specific_2.patch --]
[-- Type: text/plain, Size: 5324 bytes --]

Use setter and getter for demangled_name.
    
2010-07-12  Sami Wagiaalla  <swagiaal@redhat.com>
    
	* symtab.h (symbol_set_demangled_name): New function.
	(symbol_get_demangled_name): New function.
	* symtab.c (symbol_set_demangled_name): New function.
	(symbol_get_demangled_name): New function.
	(symbol_init_language_specific): Use demangled_name setter and getter.
	(symbol_set_names): Ditto.
	(symbol_natural_name): Ditto.
	(symbol_demangled_name): Ditto.
	* dwarf2read.c (new_symbol): Ditto.
