r242211 - in /branches/ARM/sve-branch/gcc: comm...


Author: rsandifo
Date: Fri Nov 11 17:19:33 2016
New Revision: 242211

Log:
Allow vector CONSTs

This patch allows (const ...) wrappers to be used for rtx vector
constants, as an alternative to const_vector.  This is useful
for SVE, where the number of elements isn't known until runtime.
It could also be useful in future for fixed-length vectors, to
reduce the amount of memory needed to represent simple constants
with high element counts.
