Subject: When we insert a category (or class extension) into an interface, mark
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5e9888c2786bfffa6879a08ff40f5a11545eec23;p=clang

When we insert a category (or class extension) into an interface, mark
the interface as having changed since it was originally
serialized. This ensures that we see class extensions/categories in
chained PCH files.
