Subject: undefined references to __udivdi3 on powerpc
Date: Thu, 28 Feb 2008 14:37:18 +0100	[thread overview]
Message-ID: <20080228133718.GA8383@aepfle.de> (raw)


While debugging __divdi3 calls in drivers/crypto/hifn_795x.c (due to the
ndelay() delay call with a s64), I found even more breakage of that
sort. This is after a allnoconfig with ARCH=powerpc in 2.6.25-rc3,
plus CONFIG_MODULES=y and CONFIG_CRYPTO_DEV_HIFN_795X=y:

  LD      .tmp_vmlinux1

  (.text+0x221a0): undefined reference to `__umoddi3'

  make[1]: *** [.tmp_vmlinux1] Error 1

But its not a regression, 2.6.24 allnoconfig does not link either on
powerpc32. 

How can this be fixed?

Olaf
