    • Enable vect_float with S/390 VXE and adjust testcases · 26412773 
      The target supports routines provide vect_double and vect_float but
these do not appear to be used consequently in the vect testcases.
With z13 we only have support for vector double but with z14 also for
vector float.  This patch adds vect_float to the testcases using the
float data type and make the vect_float target check to return 1 only
on z14.

    • Fix PR82396: qsort comparator non-negative on sorted output · 3e3d1b23 
      r253236 broke AArch64 bootstrap. Earlier revision r253071 changed scheduling
behaviour on AArch64 as autopref scheduling no longer checks the base.

This patch fixes the bootstrap failure and cleans up autopref scheduling.
The code is greatly simplified.  Sort accesses on the offset first, and
only if the offsets are the same fall back to other comparisons in
rank_for_schedule.  This doesn't at all restore the original behaviour
since we no longer compare the base address, but it now defines a total
sorting order.  More work will be required to improve the sorting so
that only loads/stores with the same base are affected.
