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. *** Changes in v2 *** Remove HVX tests from makefile to avoid need for toolchain upgrade # gpg: Signature made Wed 03 Nov 2021 05:14:44 PM EDT # gpg: using RSA key 7B0244FB12DE4422 # gpg: Good signature from "Taylor Simpson (Rock on) <tsimpson@quicinc.com>" [marginal] # gpg: WARNING: This key is not certified with sufficiently trusted signatures! # gpg: It is not certain that the signature belongs to the owner. # Primary key fingerprint: 3635 C788 CE62 B91F D4C5 9AB4 7B02 44FB 12DE 4422 * remotes/quic/tags/pull-hex-20211103: (30 commits) Hexagon HVX (tests/tcg/hexagon) histogram test Hexagon HVX (tests/tcg/hexagon) scatter_gather test Hexagon HVX (tests/tcg/hexagon) hvx_misc test Hexagon HVX (tests/tcg/hexagon) vector_add_int test Hexagon HVX (target/hexagon) import instruction encodings Hexagon HVX (target/hexagon) instruction decoding Hexagon HVX (target/hexagon) import semantics Hexagon HVX (target/hexagon) helper overrides - vector stores Hexagon HVX (target/hexagon) helper overrides - vector loads Hexagon HVX (target/hexagon) helper overrides - vector splat and abs Hexagon HVX (target/hexagon) helper overrides - vector compares Hexagon HVX (target/hexagon) helper overrides - vector logical ops Hexagon HVX (target/hexagon) helper overrides - vector max/min Hexagon HVX (target/hexagon) helper overrides - vector shifts Hexagon HVX (target/hexagon) helper overrides - vector add & sub Hexagon HVX (target/hexagon) helper overrides - vector assign & cmov Hexagon HVX (target/hexagon) helper overrides for histogram instructions Hexagon HVX (target/hexagon) helper overrides infrastructure Hexagon HVX (target/hexagon) TCG generation Hexagon HVX (target/hexagon) helper functions ...
