Subject: [PATCH v3 07/22] dyndbg: repack _ddebug structure
Date: Sat, 23 Dec 2023 02:51:16 +0100 [thread overview]
Message-ID: <20231223015131.2836090-8-lb@semihalf.com> (raw)
In-Reply-To: <20231223015131.2836090-1-lb@semihalf.com>
From: Jim Cromie <jim.cromie@gmail.com>
Move the JUMP_LABEL to the top of the struct, since they're both
align(8) and this closes a pahole (unfortunately trading for padding,
but still).
