Subject: Simplify some control flow and remove a call to TryAnnotateCXXScopeToken
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=532e19b4e18585d959065e407c51e625baf26d81;p=clang

Simplify some control flow and remove a call to TryAnnotateCXXScopeToken
that isn't doing what is desired. It was annotating the current token
not the 'next' token.  This code should be fixed.
