[Qemu-devel] [PATCH v2 00/16] target/xtensa: switch to libisa |

Hello,
this series adds libisa to the Xtensa target, changes decoder and
instruction translators to use it, switches existing xtensa cores
to use it, adds support for a number of new instructions and adds
disassembler for Xtensa.
Libisa is the canonical way of dealing with Xtensa instructions
decoding and encoding. Libisa is a configuration-independent library
with a stable interface plus generated configuration-specific
xtensa-modules.c file with implementations of decoding and encoding
functions. Libisa is MIT-licensed and originally distributed
xtensa-modules.c files are also MIT-licensed and are available as a
part of the xtensa configuration overlay.
This transition makes it possible to support variable-encoding
instructions of the core ISA, like const16, and will allow to support
advanced Xtensa features, like FLIX and TIE.
Development branch is available at:
git://github.com/OSLL/qemu-xtensa.git xtensa-libisa
Changes v1->v2:
- add sed transformation to target/xtensa/import-core.sh that drops
#include "ansidecl.h" from imported xtensa-modules.c;
- drop #include "ansidecl.h" from xtensa-modules.c for converted cores;
- reimplement translate_const16 using tcg_gen_deposit_i32.
