Get a call stack sample from the isolate.

Parameters

isolate	The isolate.
state	Register state.
record_c_entry_frame	Include or skip the runtime function.
frames	Caller allocated buffer to store stack frames.
frames_limit	Maximum number of frames to capture. The buffer must be large enough to hold the number of frames.
sample_info	The sample info is filled up by the function provides number of actual captured stack frames and the current VM state.
use_simulator_reg_state	When set to true and V8 is running under a simulator, the method will use the simulator register state rather than the one provided with \|state\| argument. Otherwise the method will use provided register \|state\| as is.

Note: GetStackSample is thread and signal safe and should only be called when the JS thread is paused or interrupted. Otherwise the behavior is undefined.

Initialize a tick sample from the isolate.

Parameters

isolate	The isolate.
state	Execution state.
record_c_entry_frame	Include or skip the runtime function.
update_stats	Whether update the sample to the aggregated stats.
use_simulator_reg_state	When set to true and V8 is running under a simulator, the method will use the simulator register state rather than the one provided with \|state\| argument. Otherwise the method will use provided register \|state\| as is.
