[PATCH v2 0/3] Hexagon (target/hexagon) Improve USR handling

Posted by Taylor Simpson 1 week, 2 days ago

Currently, any instruction that writes USR disables short-circuiting a
packet.  When the write is implicit, we can allow the short-circuit.

Changes in v2:
- Properly handle implicit USR writes when packet commit is necessary
- Added test case

Taylor Simpson (3):
  Hexagon (target/hexagon) Add pkt_need_commit argument to arch_fpop_end
  Hexagon (target/hexagon) Implicit writes to USR don't force packet
    commit
  Hexagon (tests/tcg/hexagon) Add test for USR changes in packet
