From 6f8270197a2909607f2c076018e30677bbac652e Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Wed, 13 May 2020 18:04:30 +0100 Subject: [PATCH] gdb: Convert language la_sniff_from_mangled_name field to a method This commit changes the language_data::la_sniff_from_mangled_name function pointer member variable into a member function of language_defn. Previously the la_sniff_from_mangled_name pointer was NULL for some languages, however, all uses of this function pointer were through the function language_sniff_from_mangled_name which provided a default implementation. This default implementation now becomes the implementation in the base class language_defn, which is then overridden as required in various language sub-classes. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_sniff_from_mangled_name): Delete function, implementation moves to...
