82 | trace : set a tracepoint on a function, line, or address. | |
83 | info trace : list all debugger-defined tracepoints. | |
84 | delete trace : delete one or more tracepoints. | |
85 | enable trace : enable one or more tracepoints. | |
86 | disable trace : disable one or more tracepoints. | |
87 | actions : specify actions to be taken at a tracepoint. | |
88 | passcount : specify a pass count for a tracepoint. | |
89 | tstart : start a trace experiment. | |
90 | tstop : stop a trace experiment. | |
91 | tstatus : query the status of a trace experiment. | |
92 | tfind : find a trace frame in the trace buffer. | |
93 | tdump : print everything collected at the current tracepoint. | |
94 | save-tracepoints : write tracepoint setup into a file. | |
95 | ||
96 | This module defines the following user-visible debugger variables: | |
97 | $trace_frame : sequence number of trace frame currently being debugged. | |
98 | $trace_line : source line of trace frame currently being debugged. | |
99 | $trace_file : source file of trace frame currently being debugged. | |
100 | $tracepoint : tracepoint number of trace frame currently being debugged. | |
