r242176 - in /branches/ARM/sve-branch/gcc: emit...


Author: rsandifo
Date: Fri Nov 11 17:13:21 2016
New Revision: 242176

URL: https://gcc.gnu.org/viewcvs?rev=242176&root=gcc&view=rev
Log:
Add subreg_memory_offset helper functions

This patch adds routines for converting a SUBREG_BYTE offset into a
memory address offset.  The two only differ for paradoxical subregs,
where SUBREG_BYTE is always 0 but the memory address offset can be
negative.
