Hi All,
Here is a simple patch for gcc.dg/ifcvt5.c test - detect "6 basic
blocks" string in rtl dump also to accept speculative motion of
else-part of if-stmt before test-part aka IF-CASE-2.
Is it OK for trunk?

* gcc.dg/ifcvt5.c: Detect '6 basic blocks' in rtl dump also.
Rather than change the expected output, I think this will do the trick.
Essentially by using a generic "word_mode" type we avoid the problems
with ports that promote parameters to word sized objects.
I've verified this passes on my sparc cross compiler as well as x86_64
native.
Installed on the trunk.
Thanks,
Jeff
