Debug Information for Windows* Application Binaries

Intel® VTune™
Profiler
 requires debug information for the binary files it analyzes to obtain accurate performance data and enable source analysis.

Generate Debug Information in the PDB Format

On Windows* operating systems, debug information is provided in PDB files. Make sure both your system and application libraries/executable have PDB files.
By default, the Microsoft Visual Studio* IDE does not generate PDB information in the
Release
 mode. For better results with the
VTune
Profiler
, enable symbol generation manually.
To generate debug information for your binary files:
  1. Right-click your C++ project and select the
    Properties
     item in the context menu.
    The
    <
    your_project
    > Property Pages
     dialog box opens.
  2. From the
    Configuration
     drop-down list, choose the
    Release
     configuration.
    It may be already selected if your current configuration in the Visual Studio environment is Release.
  3. From the left pane, select
    Configuration Properties > C/C++ > General
    .
  4. In the
    Debug Information Format
     field, choose
    Program Database (/Zi)
    .
  5. From the left pane, select
    Configuration Properties > Linker > Debugging
    .
  6. In the
    Generate Debug Info
     field, choose
    Generate Debug Information (/DEBUG)
    .
  7. Click
    OK
     to close the dialog box.
If you configured Visual Studio to generate debug information for your files, you cannot "fix" previous results because the executable and the debug information do not match the executable you used to collect the old results.
To generate a native .PDB file for a native image of .NET* managed assembly:
Use the Native Image Generator tool (
Ngen.exe
) from the .NET Framework. Make sure the search directories, specified in the
Binary/Symbol Search
 dialog box, include path to the generated
.pdb
 file.

Generate Debug Information for SYCL Applications

To enable performance profiling and generate debug information for SYCL applications running on a GPU, make sure to compile your code with
-gline-tables-only
 and
-fdebug-info-for-profiling
 options.
