The la_get_string member of struct language_defn was intended to provide a way to fetch string data from a "string" object in a language-dependent way. However, it turned out that this was never needed, and was only ever implemented for C. This patch removes the language hook entirely. gdb/ChangeLog 2019-11-05 Tom Tromey <tom@tromey.com> * rust-lang.c (rust_language_defn): Update. * python/py-value.c (valpy_string): Call c_get_string. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.c (unknown_language_defn, auto_language_defn): Update. (default_get_string): Remove. * guile/scm-value.c (gdbscm_value_to_string): Use c_get_string. * go-lang.c (go_language_defn): Update. * f-lang.c (f_language_defn): Update. * d-lang.c (d_language_defn): Update. * c-lang.c (c_language_defn, cplus_language_defn) (asm_language_defn, minimal_language_defn): Update. * ada-lang.c (ada_language_defn): Update. * language.h (struct language_defn) <la_get_string>: Remove.
