[PATCH] D31996: Make Gentoo GNU GCC Config override whitespace tolerant

[Craig Topper via Phabricator via cfe-commits]

craig.topper added inline comments.


================
Comment at: lib/Driver/ToolChains/Gnu.cpp:2176
     for (StringRef Line : Lines) {
+      StringRef TrimLine = Line.trim();
       // CURRENT=triple-version
----------------
Can we just do

Line = Line.trim()

so we won't have an extra StringRef and no one can misuse the untrimmed on in the future.
