[PATCH 0/4] S390: Vector ABI support

[Andreas Arnez <arnez@linux.vnet.ibm.com>]

This small patch series introduces vector ABI support for S/390
targets to GDB.  When an inferior uses the vector ABI, vector
arguments are now passed correctly to inferior functions, and a
function's return value of vector type can now be inspected and set
correctly.

Patch #1 fixes a minor issue in is_power_of_two(), which is used by
s390_push_dummy_call().  Patches #2 and #3 restructure the
implementations of s390_push_dummy_call() and s390_return_value(),
respectively, such that they become better readable and extensible,
and such that they can more easily be extended towards the vector ABI.
Patch #4 then adds the vector ABI support itself.

Andreas Arnez (4):
  S390: For zero, let is_power_of_two() return false
  S390: Restructure s390_push_dummy_call
  S390: Re-arrange implementation of s390_return_value
  S390: Vector ABI support
