Subject: [-mm patch] always enable regparm on i386
Date: Sun, 27 Mar 2005 22:21:16 +0200 [thread overview]
Message-ID: <20050327202116.GP4285@stusta.de> (raw)
The patch below always enables regparm on i386 (with gcc >= 3.0).
With this patch, it should get a better testing coverage in -mm.
This patch should help to find bugs that show up with regparm enabled.

Compile the kernel with -mregparm=3. This uses an different ABI
and passes the first three arguments of a function call in registers.
