Subject: Silence Visual C++ warning C4189: 'Result' : local variable is initialized but not... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9591d15e42abfcacb0225e54ad4a48b215be0726;p=clang

Silence Visual C++ warning C4189: 'Result' : local variable is initialized but not referenced.

Sadly, LLVM_ATTRIBUTE_UNUSED does nothing with Visual C++ which means
we'll have to workaround such cases again and again.
