Author: andrew Date: Sun Dec 14 18:01:09 2014 New Revision: 275771 URL: https://svnweb.freebsd.org/changeset/base/275771 Log: MFC 275337: There is no need to use FUNC_END with aeabi_ldiv0 or aeabi_idiv0 as they are aliases. Sponsored by: ABT Systems Ltd MFC 275380: Use the floating-point instruction on ARMv7 as the clang 3.5 integrated assembler doesn't allow these two instructions to use co-processor 11.
