==========

As forwarding needs hand-written assembly for each combination of CPU
architecture, executable format and calling convention, it is only available
for the following platforms (except resolveClassMethod: and
resolveInstanceMethod:, which are always available):

  * AMD64 (SysV/ELF, Apple/Mach-O, Win64/PE)
  * ARM (EABI/ELF, Apple/Mach-O)
  * ARM64 (Apple/Mach-O)
  * MIPS (O32/ELF, EABI/ELF)
  * PPC (SysV/ELF, EABI/ELF, Apple/Mach-O)
  * x86 (SysV/ELF, Apple/Mach-O, Win32/PE)


Apple means both, the Apple ABI and runtime.
