From: Tom Tromey <tromey@sourceware.org> To: gdb-cvs@sourceware.org Subject: [binutils-gdb] Make call_site_target members private Date: Mon, 28 Mar 2022 19:56:08 +0000 (GMT) [thread overview] Message-ID: <20220328195608.76F273858036@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=797662d7ef6705f9c300cb3e9a78f17f0f2aedad commit 797662d7ef6705f9c300cb3e9a78f17f0f2aedad Author: Tom Tromey <tromey@adacore.com> Date: Thu Nov 18 12:26:02 2021 -0700 Make call_site_target members private This makes the data members of call_site_target 'private'. This lets us remove most of its public API. call_site_to_target_addr is changed to be a method of this type. This is a preparatory refactoring for the fix at the end of this series.
