[LLVMdev] Extracting an AST to Graphviz using Clang

[Carlos Andrade]

Hi Joey!

Thanks I just replied your message on stack and I was actually looking into
this right now. Is this the option? I just wanted to confirm:


   - make [-j] - The -j specifies the number of jobs (commands) to run
   simultaneously. This builds both LLVM and Clang for Debug+Asserts mode. The
   --enabled-optimized configure option is used to specify a Release build.


The -j parameter is the right one?

Thank you,

Carlos Andrade
