It seems there have only been a small amount to the compiler-rt source code in the mean time. I'd rather have the code in sync as much as possible by the time we release 9.0. Changes: - The libcompiler_rt library is now dual licensed under both the University of Illinois "BSD-Like" license and the MIT license. - Our local modifications for using .hidden instead of .private_extern have been upstreamed, meaning our changes to lib/assembly.h can now be reverted. - A possible endless recursion in __modsi3() has been fixed. - Support for ARM EABI has been added, but it has no effect on FreeBSD (yet). - The functions __udivmodsi4 and __divmodsi4 have been added. Requested by: many, including bf@ and Pedro Giffuni
