This series adds support for the Hexagon processor with Linux user support See patch 02/34 Hexagon README for detailed information.
Once the series is applied, the Hexagon port will pass "make check-tcg". The series also includes Hexagon-specific tests in tcg/tests/hexagon. We have a parallel effort to make the Hexagon Linux toolchain inside a docker container publically available. *** Future items under consideration *** Use qemu softfloat Use qemu decodetree *** Known

Remove substantial portions of the code to facilitate review - Plan to submit subsequent patches - Hexagon Vector eXtensions (HVX) - Circular and bit-reverse addressiong - Add/sub-with-carry - Unused insn_t and pkt_t fields - Unused instruction attributes - All TCG overrides except instructions with multiple definitions - Unused macros - Unused reg fields - COUNT_HEX_HELPERS Use Laurent's gensyscall.sh script to generate linux-user/hexagon/syscall_nr.h Handle mem_noshuf Remove "RsV = RsV" per review feedback Simplify include file structure Add directed tests in <qemu>/tests/tcg/hexagon Rework the python scripts to generate one header file at a time Change fWRAP_* macros to fGEN_TCG_* *** Changes in v2 *** - Use scripts/git.orderfile Taylor Simpson (34): Hexagon Update MAINTAINERS
