Yes, the patterns implemented in match.pd have been removed from
fold-const.c.  So this will definitely affect some testcases
with respect to constant expressions no longer being constant
for example.

I didn't even expect that bootstrap succeeds - that it does is
good news.

Ah, I'm trying --with-cpu=default32 then while waiting for cfarm
access.

Thanks,
