patch to enable response file support in ParseCommandLineOptions

Project Infrastructure LLVM Dev List Archives
#1

Hi,

I am sending a patch to enable response file support in ParseCommandLineOptions. With this change, all llvm tools will support response file. This helps overcome the command line length limit which we encountered recently.

Hi Sam, please add a testcase. Does this cause any regressions?

Ciao, Duncan.
