Subject: Add back some dead code.
X-Git-Tag: android-x86-7.1-r4~31453
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=6e37dd76f66dcf057927a32b3c5b1977369359da;p=android-x86%2Fexternal-llvm.git

Add back some dead code.

It was there just to avoid warnings. Add a LLVM_ATTRIBUTE_UNUSED
attribute so that it doesn't produce warnings with gcc 6.
