I added aarch64_be-linux-gnu_ilp32 a while ago to my list of targets
to test before pushing global changes, but I'm thinking I ought to drop
it. The ld testsuite gets segmentation faults, and the list of fails
is quite large. No doubt it would be worse if I had installed a
cross-compiler for the target.

The Linux kernel support for ILP32 never made it upstream; glibc
support never made it upstream; though there was a branch on
sourceware.org at one time. And we (the folks who were working on
ILP32 at the time) never tested big-endian support.
Thanks,

Thanks for the info.
I only chose aarch64_be-linux-gnu_ilp32 because I hadn't previously
tested any aarch64 BE targets. Having just now tested
aarch64-linux-gnu_ilp32 and getting these results,

the message is fairly loud and clear that this is an experimental
target.
BTW, aarch64_be-linux-gnu gets the same segfaults I was seeing with
aarch64_be-linux-gnu_ilp32.
