Subject: [PATCH 11/11] install_variable cannot fail
Date: Sat, 24 Oct 2020 15:08:56 -0600	[thread overview]
Message-ID: <20201024210856.12021-12-tom@tromey.com> (raw)
In-Reply-To: <20201024210856.12021-1-tom@tromey.com>

I noticed that install_variable will never return false, so this patch
changes the return type to void.  I couldn't find a spot in history
where it did return false, maybe it's always been like this.

	* varobj.c (varobj_create): Update.
	(install_variable): Return void.
