Subject: Disable MSVC warnings on ISL.
X-Git-Tag: llvmorg-4.0.0-rc1~10460
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=349779cc99824f79c79d6c534af5e71bd9cac91a;p=platform%2Fupstream%2Fllvm.git

Disable MSVC warnings on ISL.

Disable some Visual C++ warnings on ISL. These are not reported by GCC/Clang in
the ISL build system. We do not intend to fix them in the Polly in-tree copy,
hence disable these warnings.
