Raw Blame History

# 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
#
# NOTE: Use YAML comments only on comment-only lines (not trailing content):
# Node.js 'yamljs' seems to refuse parsing trailing comments in some cases.
