Hi,
I am trying to turn on libffi for mips-rtems and ran into this
piece of code in libffi/include/ffi_mips.h
#if !defined(_MIPS_SIM)
-- something is very wrong --
#else
# if _MIPS_SIM==_ABIN32 && defined(_ABIN32)
# define FFI_MIPS_N32
# else
# if defined(__GNUC__)
# define FFI_MIPS_O32
# else
# if _MIPS_SIM==_ABIO32
# define FFI_MIPS_O32
# else
-- this is an unsupported platform --
# endif
# endif
# endif
#endif
It looks like the unix mips platforms go to great pains to define
this based upon gcc arguments.
I have no idea how it should be set for a generic mips-elf
embedded target. Suggestions appreciated.
