Subject: V4L2: __ucmpdi2 undefined on ppc
Date: Wed, 13 Dec 2006 14:11:04 +0200 (EET)	[thread overview]
Message-ID: <> (raw)

  MODPOST 618 modules
WARNING: "__ucmpdi2" [drivers/media/video/v4l2-common.ko] undefined!

This 32-bit ppc architecture, using gcc version 4.1.2 20061115 
(prerelease) (Debian 4.1.1-21). .config below if important.

__ucmpdi2 seems to be 64-bit comparision. gcc seems to use it for switch 
statements on 64-bit values.

drivers/media/video/v4l2-common.c::v4l2_norm_to_name seems to be one 
such switch statement - type of id is v4l2_std_id which is 64-bit.

Should ppc have __ucmpdi2 defined in arch-specific lib? Some other 
architectures seem to implement it (arm, arm26, frv, h8300).
