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 <tom@tromey.com> * 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. (rust_language_defn): Update. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_sniff_from_mangled_name): New function. (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.h (struct language_defn) <la_sniff_from_mangled_name>: New field. (language_sniff_from_mangled_name): Declare. * language.c (language_sniff_from_mangled_name): New function. (unknown_language_defn, auto_language_defn, local_language_defn): Update. * jv-lang.c (java_sniff_from_mangled_name): New function. (java_language_defn): Use it. * go-lang.c (go_sniff_from_mangled_name): New function. (go_language_defn): Use it. * f-lang.c (f_language_defn): Update. * defs.h (enum language): Reorder. * d-lang.c (d_sniff_from_mangled_name): New function.
