[Qemu-devel] [RFC PATCH v4 34/75] target/i386: introduce sse-opcode.inc.h

[Jan Bobek]

This header is intended to eventually list all supported instructions
along with some useful details (e.g. mnemonics, opcode, operands etc.)
It shall be used (along with some preprocessor magic) anytime we need
to automatically generate code for every instruction.
