Hi All,

  It looks like the fix for bootstrap/9036 also fixes target/9150

ice.c:
---------------
float
foo(float bar)
{
     return (((bar) < 0.0f) ? -bar : bar);
}
----------------

% /usr/local/gcc-3.4-20030108-i686-pc-linux-gnu/bin/gcc -c ice.c -msse2 -fpic
ice.c: In function `foo':
ice.c:5: error: unrecognizable insn:
