Message

Taylor Simpson July 5, 2021, 11:34 p.m. UTC

This series adds support for the Hexagon Vector eXtensions (HVX)

These instructions are documented here
https://developer.qualcomm.com/downloads/qualcomm-hexagon-v66-hvx-programmer-s-reference-manual

Hexagon HVX is a wide vector engine with 128 byte vectors.

See patch 01 Hexagon HVX README for more information.

*** Known checkpatch issues ***

The following are known checkpatch errors in the series
    target/hexagon/gen_semantics.c    Suspicious ; after while (0)
    tests/tcg/hexagon/hvx_misc.c      Spaces around operator in macro invocation
