Data Space commands are applicable only to hardware counter experiments where memoryspace/dataspace data was recorded, either by default or explicitly for precise counters on either Solaris x86 or SPARC systems. See the collect (1) man page for more information.
Dataspace data is only available for profile hits that occurred in functions that were compiled with the -xhwcprof flag. The -xhwcprof flag is applicable to compiling with the C, C++ and Fortran compilers and is only meaningful on SPARC platforms; it is ignored on other platforms.
See Hardware Counter Profiling Data for more information about these types of data. See Hardware Counter Profiling with collect -h for information about the command used to perform hardware counter overflow profiling.
For information about the –xhwcprof compiler option, see Oracle Solaris Studio 12.4: Fortran User’s Guide , Oracle Solaris Studio 12.4: C User’s Guide , or Oracle Solaris Studio 12.4: C++ User’s Guide .
