Author: erichkeane Date: Fri Oct 20 12:18:30 2017 New Revision: 316225 URL: http://llvm.org/viewvc/llvm-project?rev=316225&view=rev Log: Allow /showIncludes with /P
r213589 was checked in as a solution to https://bugs.llvm.org/show_bug.cgi?id=20336. However, it is possible to use /EP with /P to suppress #line directives AND output to a file. There is no reason in that case to suppress /showIncludes.
