[PATCH] [AArch64] ILP32 math changes

[Steve Ellcey]

Since Szabolcs has expressed interest in getting some aarch64 ILP32
changes into glibc mainline (if they don't affect the kernel or glibc
ABI) I am resubmitting this patch for approval in advance of the main
ILP32 support patches. Â I updated it with Richard Henderson's code (but
only doing it when the incoming argument is large). Â I tested it on
aarch64 ILP32 and LP64 with no regressions.

Is this something that can be checked in now withnout waiting for the
kernel ILP32 support?
