##
# @ReplayInfo:

# Retrieve the record/replay information. It includes current
# instruction count which may be used for @replay-break and
# @replay-seek commands.
#
# Returns: record/replay information.

##
# @replay-break:
#
# Set replay breakpoint at instruction count @icount. Execution stops
# when the specified instruction is reached. There can be at most one
# breakpoint. When breakpoint is set, any prior one is removed. The
# breakpoint may be set only in replay mode and only "in the future",
# i.e. at instruction counts greater than the current one. The
# current instruction count can be observed with @query-replay.
#
# @icount: instruction count to stop at
#
# Since: 5.2

#
# Remove replay breakpoint which was set with @replay-break. The

#
# Since: 5.2

# .. qmp-example::
#
# -> { "execute": "replay-delete-break" }
# <- { "return": {} }

# @replay-seek:
#
# Automatically proceed to the instruction count @icount, when
# replaying the execution. The command automatically loads nearest
# snapshot and replays the execution to find the desired instruction.
# When there is no preceding snapshot or the execution is not
# replayed, then the command fails. Instruction count can be obtained
# with the @query-replay command.
#
# @icount: target instruction count
#
# Since: 5.2
