Subject: <rdar://problem/13477190> Give the Clang module cache directory some structure, so... 
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=23c7d67de2ddd9351ab7ecd3e5b2386e44ba333b;p=platform%2Fupstream%2Fllvm.git

<rdar://problem/13477190> Give the Clang module cache directory some structure, so it's easier to find.

We now put the Clang module cache in
<system-temp-directory>/org.llvm.clang/ModuleCache. Perhaps some day
there will be other caches under <system-temp-directory>/org.llvm.clang>.
