------- Comment #6 from dje at gcc dot gnu dot org  2010-07-21 23:52 -------
I think the thread about the patch became confused.

First, Janis essentially approved the testsuite patch.

Second, Martin commented that the failure probably was due to MOVE_RATIO not
defined.  The statement caused some misunderstanding.  MOVE_RATIO does not need
to be defined and the failure is not caused by a missing definition.  The
default value of MOVE_RATIO (used by PPC and ARM) cause the heuristic to
disable the optimization being tested.

If the optimization is not expected to occur on some platforms, then the
testcase should be disabled as implemented by the patch or the testcase
explicitly should set some gcc param that ensures the optimization will occur
on all targets.
