Subject: Enhanced serialization testing by also pretty-printing CFGs constructed from ASTs
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5656b782561f6a434fabec3c057cdbb63b55a1c8;p=clang

Enhanced serialization testing by also pretty-printing CFGs constructed from ASTs
both before and after serialization/deserialization. If the CFGs between the pre-
and post- serialized/deserialized ASTs differ, the serialization has failed.
