Subject: bug in arch/ppc/boot/common/util.S: cmplwi cr0,r3,r4 ?
Date: Wed, 3 Aug 2005 15:18:48 +0200 [thread overview]
Message-ID: <20050803131848.GA10954@janus> (raw)
I think "cmplwi" expects an immediate vale as last operand
around line 255 of arch/ppc/boot/common/util.S:
addi r4,r4,_etext@l # r8 = &_etext
1: dcbf r0,r3 # Flush the data cache
icbi r0,r3 # Invalidate the instruction cache
addi r3,r3,0x10 # Increment by one cache line
cmplwi cr0,r3,r4 # Are we at the end yet?
^^
blt 1b # No, keep flushing and invalidating
I guess it should have been:
cmplw cr0,r3,r4 # Are we at the end yet?
