Any ideas? I recall chatter on IRC that we want to merge wide-int into trunk
soon. Bootstrap failure on arm would prevent that...
Sorry for the late reply.  I hadn't forgotten, but I wanted to wait
until I had chance to look into the ICE before replying, which I haven't
had chance to do yet.
They are separable issues, so, I checked in the change.

It's a shame we can't use C++ style casts,
but I suppose that's the price to pay for being able to write
"unsigned HOST_WIDE_INT”.
unsigned_HOST_WIDE_INT isn’t horrible, but, yeah, my fingers were expecting a 
typedef or better.  I slightly prefer the int (1) style, but I think we should 
go the direction of the patch.
Well, on my list of things to try for 4.10 is to kill off HOST_WIDE_* and
require a 64bit integer type on the host and force all targets to use
a 64bit 'hwi'.  Thus, s/HOST_WIDE_INT/int64_t/ (and the appropriate
related changes).

Richard.
I should point out that there is a community that wants to go in the opposite direction here. They are the people with real 32 bit hosts who want to go back to a world where they are allowed to make hwi a 32 bit value. They have been waiting wide-int to be committed because they see this as a way to get back to world where most of the math is done natively.

I am not part of this community but they feel that if the math that has the potential to be big to be is done in wide-ints, then they can go back to using a 32 bit hwi for everything else. For them, a wide-int built on 32 hwi's would be a win.
