Can someone provide a bit of insight here - what is the difference
between TREE_READONLY and TREE_CONSTANT (and why is TREE_READONLY the
one that ipa-reference should be setting)?
It depends on what property IPA is computing. And they aren't
terribly differentiated.

Thanks very much for the thorough description. I think I understand
the distinction now.
I'm not sure how much of this will be possible before 4.1 is
released. At minimum we have to change IPA to stop setting
TREE_READONLY when DECL_SECTION_NAME is set; if we have to
live with reduced optimization so be it.
I'd be glad to create and test a patch for this, if it would be
welcomed.
