Subject: test/lit.cfg: Add PATHEXT to 'substitution', to recognize tools on Windows hosts... 
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=027f98cd3bf0c144cd8dadc6e59b373cbd17e084;p=oota-llvm.git

test/lit.cfg: Add PATHEXT to 'substitution', to recognize tools on Windows hosts. Thanks to Danil Malyshev!

Some tests on Windows use the "not" utility and fail with an error "program not executable". The reason for this error is that the name of the executable file sended to the "not" without the extension.
