Subject: [clang-proto-to-cxx] Accept protobufs with missing fields.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=fea5007e11197e02959e9ec135098e9fe56e2c9c;p=clang

[clang-proto-to-cxx] Accept protobufs with missing fields.

libprotobuf-mutator accepts protobufs with missing fields, which means
clang-proto-fuzzer does as well.  clang-proto-to-cxx should match this
behavior.
