* perf intel-pt: Make logging slightly more efficientAdrian Hunter2015-09-28
| | | | | | | | | | Logging is only used for debugging. Use macros to save calling into the functions only to return immediately when logging is not enabled.

* perf tools: Add Intel PT logAdrian Hunter2015-08-17
Add a facility to log Intel Processor Trace decoding. The log is intended for debugging purposes only. The log file name is "intel_pt.log" and is opened in the current directory. The log contains a record of all packets and instructions decoded and can get very large (10 MB would be a small one).
