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.
