Description: Binary data
Hi All,
Here is a fix for PR 61576 - additional test was added that block
containing reduction statement is predecessor of block containing phi
to choose the correct condition.
Bootstrap and regression testing did not show any new failures.
Is it OK for trunk?

Hi All,
Here is a simple patch which removes restriction on outer-loop
vectorization - allow references in inner-loop with zero step. This
case was found in one important benchmark.

Hi All,
Here is a simple fix which allows duplication of outer loops to

pragma omp simd.

int will be "after labels" Note also that phi result can
have use in this block too, so we can't put predication code to the
block end.
Let me know if you still have any questions.

Hi All!
Here is a simple patch to not perform instruction reordering for
selective scheduling since it uses interface of list scheduling
defined in "sched-int.h".
Bootstrap and regression testing did not show any new failures.
Is it OK for trunk?

Hi All,
I prepared new patch which includes test-case.
I can't agree with patch proposed by Alexander since other functions
doing ready list reordering also use HID interface, so I put escape
check in ix86_sched_reorder.
Is it OK for trunk?

Here is updated patch accordingly to Alexander comments.
BTW another function using HID interface is do_reorder_for_imul and it
is called from ix86_sched_reorder.
Is it OK for trunk?

consider remainder for possible vectorization of inner-loop as we can see
on the following example:
for (i = 0; i < n; i++) {
diff = 0;
for (j = 0; j < M; j++) {
diff += in[j+i]*coeff[j];
}
out[i] = diff;
}
Is it worth to fix it?
