My reply had nothing to do with the demangler policy, and everything
to do with patch committal policy.  You requested approval for a
patch, and committed it without waiting for approval.  Such sloppy
adherence to procedures is especially bad in libiberty, which services
many projects.

As for the patch itself, I answered that already - there are no
obvious changes to testsuites.  Each and every change to existing test
cases must be discussed, because they could potentially harm backwards
compatibility.
