LLC -view-isel-dags option on Windows/Cygwin build

I was able to compile LLVM on windows (llvm2.3) using Visual studio. When I type llc -help command, I do not see -view-isel-dags option (http://llvm.org/docs/CodeGenerator.html document mentions about it). Is this option is supported on Windows (or Cygwin) build?

Thanks a bunch,

Does it show up when you use -help-hidden?

Nope. I don’t see this option with -help-hidden.

It requires GraphViz which should be available for Windows. But make sure it’s in the search path before you configure llvm.
