From 8b302db80cb07f5f3264b50e1b51fdb8ecb29183 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 26 May 2016 15:04:07 -0600 Subject: Move logic out of symbol_find_demangled_name This patch moves most of the demangling logic out of symbol_find_demangled_name into the various language_defn objects. The simplest way to do this seemed to be to add a new method to language_defn. This is shame given the existing la_demangle, but given Ada's unusual needs, and the differing demangling options between languages, la_demangle didn't seem to fit. In order to make this work, I made enum language order-sensitive. This helps preserve the current ordering of demangling operations. 2016-06-23 Tom Tromey * symtab.c (symbol_find_demangled_name): Loop over languages and use language_sniff_from_mangled_name. * rust-lang.c (rust_sniff_from_mangled_name): New function.
