Subject: Do not to perform RUN line substitution of llc if that's prefixed by a hypnen
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=dafd1a63119dc55af71c4582148ce72d573cdea6;p=oota-llvm.git

Do not to perform RUN line substitution of llc if that's prefixed by a hypnen
(-llc), similarly to the way it was done for clang and llvmc.

This doesn't affect the upstream llvm tests but helps when developing custom
LLVM-based tools and testing them within the LLVM regression framework.
