X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e4bdae78c69d2a09ee96619cc5ccf81441674412;p=clang

Driver: Switch to using explicit {getLast,has}ArgNoClaim functions instead of taking a Claim argument.
 - Most driver code always claims, and bool arguments don't play nice with the overloads.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89308 91177308-0d34-0410-b5e6-96231b3b80d8
