* This tool is part of a test that verifies that Pin's "fast" signal handling
|
|
* works.
|
|
*
|
|
* The test runs this tool on an application that delivers lots of signals.
|
|
* The tool inserts a slow out-of-line analysis routine at every BBL,
|
|
* so we expect a lot of the signals to be delivered while inside the analysis
|
|
* function. The test looks at internal statistics counters to verify that
|
|
* the majority of these signals are delivered using the "fast" algorithm.
|
|
* This validates that Pin's "current location" markers are set correctly, etc.
