From: Pedro Alves <palves@sourceware.org> To: gdb-cvs@sourceware.org Subject: [binutils-gdb] Convert location_spec_to_string to a method Date: Fri, 17 Jun 2022 09:23:40 +0000 (GMT) [thread overview] Message-ID: <20220617092340.A82393857B82@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=709438c75abc52cdc4888e7eaa089c2709c75a07 commit 709438c75abc52cdc4888e7eaa089c2709c75a07 Author: Pedro Alves <pedro@palves.net> Date: Fri May 27 16:44:02 2022 +0100 Convert location_spec_to_string to a method This converts location_spec_to_string to a method of location_spec, simplifying the code using it, as it no longer has to use std::unique_ptr::get().
