Description
This option would be used by decode_opcode() and decode_eflags_usage(). A full decode of operands adds significant overhead.
Contributor guide
Research direction
Locate the AArch64 decoder and the decode_opcode() and decode_eflags_usage() entry points mentioned in the issue. Trace how they currently trigger full operand decoding, then verify that the new option returns opcode and flag-usage information without that overhead.
