No optimization options were specified; profile info will not be collected
/GL and /LTCG were specified, but no optimizations were requested, so no .pgc files will be generated and, therefore, no profile-guided optimizations will be possible.
If you want .pgc files to be generated when you run your application, specify one of the /O compiler options.
The following sample generates C4964:
// C4964.cpp
// compile with: /W1 /GL /link /ltcg:pgi
// C4964 expected
// Add /O2, for example, to the command line to resolve this warning.
int main() {
int i;
}
