Is there any way to get the number of parameters a function has declared from a JSFunction object?
I'm asking because I want to get the argument values a function is receiving in an op_call (in the interpreter). I copied this snipper of code for the case where a host function is called: Register* thisRegister = callFrame->registers() - RegisterFile::CallFrameHeaderSize - argCount; ArgList args(thisRegister + 1, argCount - 1); The problem is that argCount is the number of arguments passed, and so, if the function takes 5 arguments and 3 are passed, I'm not getting the first 2, only the last 3, two of which show up as "undefined". Hence I believe I would need the number of arguments the function declares takes to properly compute the register offset. -- View this message in context: http://old.nabble.com/Function---Property-Names-tp28394250p28442878.html Sent from the Webkit mailing list archive at Nabble.com. _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
