Subject: [IR] Have AttrBuilder::clear clear `TargetDepAttrs`.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=dc0eb17133567488576c3541a450665d51c3a3bb;p=oota-llvm.git

[IR] Have AttrBuilder::clear clear `TargetDepAttrs`.

Test case attached -- currently the parser smears the "foo bar" to all
of the formal arguments.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@246812 91177308-0d34-0410-b5e6-96231b3b80d8
