I forgot about those, thanks.  These tests do indeed pass on spu-elf
now on mainline.  I've committed the following patch to re-enable
the test cases on SPU on mainline:

  gcc.dg/torture/fp-int-convert-float.c
  gcc.dg/torture/fp-int-convert-timode.c

These other test cases that I had also disabled for SPU as part of
http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00967.html
remain disabled, as they test specifically for round-to-nearest
behaviour:

  gcc.c-torture/execute/ieee/920518-1.c
  gcc.c-torture/execute/ieee/20010114-2.c
  gcc.c-torture/execute/ieee/20030331-1.c

Bye,
Ulrich

testsuite/ChangeLog:

	* gcc.dg/torture/fp-int-convert-float.c: Reenable test on SPU.
	* gcc.dg/torture/fp-int-convert-timode.c: Reenable "float" test on SPU.
