I run it in macos, and I build it in debug version.

I know how to dumpIR when I use javascrptcore, when I finish building, I have a executable named "jsc", then I could use :

>.  ./jsc test.js --DumpGraphAtEachPhase=true

But I don't know how to use |DumpGraphAtEachPhase| when I use MiniBrowser.app(not jsc ), like:

>.   ./MiniBrowser test.html --DumpGraphAtEachPhase=true


Thx
