<pre>lib/Sema/SemaDecl.cpp:10867:24: warning: & has lower precedence than !=; !=
will be evaluated first [-Wparentheses]
while (S->getFlags() & Scope::TemplateParamScope != 0)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/Sema/SemaDecl.cpp:10867:24: note: place parentheses around the '!='
expression to silence this warning
while (S->getFlags() & Scope::TemplateParamScope != 0)

to evaluate it first
while (S->getFlags() & Scope::TemplateParamScope != 0)

Note that the final fix-it hint is suggesting putting the close paren in the
wrong place. Are we incorrectly assuming that the middle expression is only a
single token long here, or is the source range for that expression wrong?</pre>
