From: Pedro Alves Date: Fri, 29 Apr 2022 22:21:18 +0000 (+0100) Subject: Always pass an explicit language down to c_type_print X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1c6fbf42e5bd3045a41ad32c5efbc2ab8ca5e941;p=binutils-gdb.git Always pass an explicit language down to c_type_print The next patch will want to do language->print_type(type, ...), to print a type in a given language, avoiding a dependency on the current language. That doesn't work correctly currently, however, because most language implementations of language_defn::print_type call c_print_type without passing down the language. There are two overloads of c_print_type, one that takes a language, and one that does not. The one that does not uses the current language, defeating the point of calling language->print_type()... This commit removes the c_print_type overload that does not take a language, and adjusts the codebase throughout to always pass down a language. In most places, there's already an enum language handy. language_defn::print_type implementations naturally pass down this->la_language. In a couple spots, like in ada-typeprint.c and rust-lang.c there's no enum language handy, but the code is written for a specific language, so we just hardcode the language. In gnuv3_print_method_ptr, I wasn't sure whether we could hardcode C++ here, and we don't have an enum language handy, so I made it use the current language, just like today. Can always be improved later.
