A default expansion for MULT_HIGHPART_EXPR was proposed as part of
https://gcc.gnu.org/pipermail/gcc-patches/2020-August/551316.html
I'll split off just that part of the patch and resubmit it for review.

How does your patch expand 64-bit highpart multiply (i.e. with 128-bit full
product) on 32-bit targets?

Roger, thanks for your effort.  While I believe your patch series will
be generally useful, as far as this bug is concerned, I do not think
it makes sense to complicate things because of it.  HSA has been
removed in GCC 11 and since your patch is unlikely to be a candidate
for backport to GCC 10 or earlier, it is unlikely to fix this.  HSA
almost certainly does not have any users anyway, there is little need
to bother about it too.

Still, thanks for looking into the general issue.

As mentioned the brig front-end was removed in GCC 11 so closing as won't fix.

Actually it was removed for GCC 12 by r12-717.
