duktape/debugger/duk_opcodes.yaml

# Duktape opcode metadata for debugger.
# - See duk_debug.js for the argument formats (A_R etc).
# - Flag bits are for the whole instruction as a 32-bit integer,
#   they are not field shifted

# XXX: Need to rework after performance optimization merges which
# reworked several opcodes.
