Subject: Delay codegen to after collecting all SubobjectAdjustment so that the collection
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ecccc1e286b56330c75b443a3a14b93e1d3bdedd;p=clang

Delay codegen to after collecting all SubobjectAdjustment so that the collection
can be refactored and used in Sema.
