Subject: [PATCH 2/3] i386: Move asserts to separate x86_cpudef_validate() function
Date: Mon,  1 Feb 2021 17:54:03 -0500	[thread overview]
Message-ID: <20210201225404.3941395-3-ehabkost@redhat.com> (raw)
In-Reply-To: <20210201225404.3941395-1-ehabkost@redhat.com>

Additional sanity checks will be added to the code, so move the
existing asserts to a separate function.

Wrap the whole function in `#ifndef NDEBUG` because the checks
will become more complex than trivial assert() calls.
