Error Message: Cannot Locate Debugging Information


Debugging information (PDB files on Windows* and DWARF format on Linux*) for applications and system modules is not generally available on the system by default. Missing debug information is not critical to performance analysis but prevents
Intel® VTune™
from providing full-scale statistics on call stacks, source data, and so on.
If the
does not find debug information for the binaries, it statically identifies function boundaries and assigns hotspot addresses to generated pseudo names
for such functions, for example:
If a module is not found or the name of a function cannot be resolved, the
displays module identifiers within square brackets, for example:
If the debug information is absent, the
may not unwind the call stack and display it correctly in the
Call Stack
pane. Additionally in some cases, it can take significantly more time to finalize the results for modules that do not have debug information.


For accurate performance analysis, you are recommended to have the debug information available on the system where the
is installed. See detailed instructions to enable:

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
