Subject: [PATCH 1/4] gdb: make progspace::exec_filename private, add getter / setter
Date: Thu, 30 May 2024 14:53:53 -0400 [thread overview]
Message-ID: <20240530185509.265901-2-simon.marchi@efficios.com> (raw)
In-Reply-To: <20240530185509.265901-1-simon.marchi@efficios.com>
Just like the title says... I think this makes things a bit clearer, for
instance where the exec filename is set. It also makes the read call
sites a bit nicer, avoiding the `.get ()`.
