From: Tom Tromey <tromey@sourceware.org> To: gdb-cvs@sourceware.org Subject: [binutils-gdb] Remove some unneeded checks in Guile code Date: Thu, 28 Jul 2022 20:44:26 +0000 (GMT) [thread overview] Message-ID: <20220728204426.F108D385AC08@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=43cffa64cf72f11a95203cd89844f82aa906c7e7 commit 43cffa64cf72f11a95203cd89844f82aa906c7e7 Author: Tom Tromey <tom@tromey.com> Date: Sat May 28 21:06:19 2022 -0600 Remove some unneeded checks in Guile code The Guile code generally checks to see if an htab is non-null before destroying it. However, the registry code already ensures this, so we can change these checks to asserts and simplify the code a little.
