URL: http://llvm.org/viewvc/llvm-project?rev=182336&view=rev
Log:
Improving the previous checkin about target.load-script-from-symbol-file
There are two settings:
target.load-script-from-symbol-file is a boolean that says load or no load (default: false)
target.warn-on-script-from-symbol-file is also a boolean, it says whether you want to be warned when a script file is not loaded due to security (default: true)
the auto loading on change for target.load-script-from-symbol-file is preserved
