The following table lists warnings issued by the VSInstr.exe tool. You can use the NOWARN option along with the warning numbers to suppress the warning from appearing.
Internal Error. Cannot get the module file name for this executable.
<assembly name> is a strongly named assembly. It must be re-signed before it can be executed.
This warning occurs when a signed assembly is instrumented. You can use the sn.exe tool to resign the binary or to temporarily turn off the strong name requirement. For more information, see Strong Name Tool (Sn.exe).
Could not find function <funcname> in file <filename>
This warning occurs if a function cannot be located in the specified file.
Could not find any cross jumps to the function <funcname> in file <filename>.
This warning occurs if VSInstr cannot nullify cross jumps. Cross jumps are used for code optimization.
Function <funcname> was excluded by using the EXCLUDE command-line switch but was required because it contained a cross jump.
This warning occurs if the function was excluded by using the EXCLUDE option, but is needed during the instrumentation process. The profiler automatically includes the required function.
Internal Instrumentation Error <error text>
This warning is issued if instrumentation cannot be performed. Review the error text to determine whether it can be corrected.
Could not locate PDB for <name>
This warning occurs if the PDB file does not exist on the search path or does not match the binary.
<filename> contains no instrumentable code.
This warning is issued if the functions in the binary file were all excluded or if the specified file only contains resources.
Unable to get security attributes from <name>. Error code <code>
This warning occurs if the user does not have READ_DAC permission. During the instrumentation process, the profiler attempts to preserve the original DACL for the binary. Because the original binary is replaced with a new binary, the DACL from the original binary must be copied and applied to the new binary. This can fail if the user does not have READ_DAC access on the original binary.
Unable to set security attributes on <name>. Error code <error number>
This warning occurs if the user does not have WRITE_DAC permission. During the instrumentation process, the profiler attempts to preserve the original DACL for the binary. Because the original binary is replaced with a new binary, the DACL from the original binary must be copied and applied to the new binary. This can fail if the user does not have WRITE_DAC access on the new binary.
No functions are specifically selected for instrumentation because of -INCLUDE/-EXCLUDE options
Include/Exclude funcspec <name> does not match any functions
The image does not contain any code that can be instrumented for code coverage.
Profiler does not instrument the following type of code:
Static CRT functions
Managed methods attributed with NonUserCodeAttribute
Managed methods attributed with DebuggerHiddenAttribute
This warning is generated if, after this filtering, there is no code left.
Instrumenting this image requires it to run as a 32-bit process. The CLR header flags have been updated to reflect this.
The profiler modifies the binary so that 64-bit platforms can launch the 32-bit process in WOW64. For libraries (DLLs) this might fail if they are loaded in an existing 64-bit process. This warning notifies the user of the dependency.
The resulting instrumented image appears to be invalid, and might not run.
This message occurs when the final instrumented assembly has an invalid PE header.
