Specify this option to compile and instrument your program for analysis by the Thread Analyzer.
(For information on the Thread Analyzer, see tha(1) for details.)
By compiling with this option you can then use the Performance Analyzer to run the instrumented program with collect -r races to create a data-race-detection experiment. You can run the instrumented code standalone but it runs more slowly.
Specify -xinstrument=no%datarace to turn off this feature. This is the default.
-xinstrument must be specified with an argument.
If you compile and link in separate steps, you must specify -xinstrument=datarace in both the compilation and linking steps.
This option defines the preprocessor token __THA_NOTIFY. You can specify #ifdef __THA_NOTIFY to guard calls to libtha(3) routines.
This option also sets -g.
