|

# Example:

# <- { "return": { "mode": "play", "filename": "log.rr", "icount": 220414 } }

|
|
# 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

#
|

|
# @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.
|
|
# icount for the reference may be obtained with @query-replay command.
|
|
#
|
|
# @icount: target instruction count

# Since: 5.2
