Subject: Remove union _xivu from struct xpvav - replace it with a non-union xav_alloc.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=4f7003f5e8adb225a16f3788ec81e193021f41e5;p=p5sagit%2Fp5-mst-13.2.git

Remove union _xivu from struct xpvav - replace it with a non-union xav_alloc.

This was the only user of xivu_p1 in union _xivu, so remove that too.
