I see this problem as well, with gcc 3.3.1 and binutils 2.14.90.0.6: 
[jbarnes@tomahawk linux-2.5-bigsur]$ $CROSS_COMPILE/gcc --version 
gcc (GCC) 3.3.1 
[jbarnes@tomahawk linux-2.5-bigsur]$ $CROSS_COMPILE/ld --version 
GNU ld version 2.14.90.0.6 20030820 
 
I always see a number of these 'dependency violation' messages when I compile 
an ia64 Linux kernel.  For example: 
 
  ... 
  LD      fs/lockd/built-in.o 
{standard input}: Assembler messages: 
{standard input}:4421: Warning: Use of 'ssm' violates WAW dependency 'PSR.i' 
(impliedf) 
{standard input}:4421: Warning: Only the first path encountering the conflict 
is reported 
{standard input}:4414: Warning: This is the location of the conflicting usage 
{standard input}:4492: Warning: Use of 'ssm' violates WAW dependency 'PSR.i' 
(impliedf) 
{standard input}:4492: Warning: Only the first path encountering the conflict 
is reported 
{standard input}:4485: Warning: This is the location of the conflicting usage 
  CC      fs/nfs/dir.o 
  .... 
 
Thanks,
