Subject: [RFC PATCH 06/17] dyndbg: dynamic_debug_init - use pointer inequality, not strcmp
Date:   Mon,  5 Dec 2022 17:34:13 -0700
Message-Id: <20221206003424.592078-7-jim.cromie@gmail.com>
In-Reply-To: <20221206003424.592078-1-jim.cromie@gmail.com>

Precedence: bulk

dynamic_debug_init() currently uses strcmp to find the module
boundaries in the builtin _ddebug[] table.

The table is filled by the linker; for its content, pointer inequality
works, is faster, and communicates the data properties more tightly.
