Subject: [PCH] When keeping track of top-level decls for "targeted deserialization"
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8cceefac395d476114b3d4ecd7e969b2e1c9271d;p=clang

[PCH] When keeping track of top-level decls for "targeted deserialization"
make sure we don't mistake ParmVarDecls for top-level decls.

Fixes rdar://10920009.
