I've mentioned some improvements for unaligned and overlapping code
generation in the RISC-V call a few weeks ago. Sending this patches
now, as the release is out.
Christoph Müllner (4):
RISC-V: Add test cases for cpymem expansion
RISC-V: Allow unaligned accesses in cpymemsi expansion
RISC-V: tune: Add setting for overlapping mem ops to tuning struct
RISC-V: Allow by-pieces to do overlapping accesses in
