/Qvec-report interferes with Call Graph Instrumentation

Hi,

After spending the last 3 hours trying to figure out why the Call Graph wasn't showing the function in which 99% of program execution is spent, I finally got it to work by simply removing the /Qvec-report3 compiler switch. I have verified that this switch interferes with instrumentation on two different machines using Visual Studio .NET 2003. Perhaps only those functions in which vectorization occurs are affected -- I'm not sure.

Dear Nafis,

The switch /Qvec-report3 forces the build of some extra debugging information to enable reporting variable identifiers indetailed data dependence reports. I was not aware this interfered with call graph construction (you may want to report this through premier). Switch /Qvec-report2 (and lower) does not require this information, and still gives you information on the success and failure of vectorizing your code. Hope this helps for now at least.
