	symbols.  Add __sim_disabled_exceptions, __sim_exceptions,
	__sim_round_mode.
	* sysdeps/powerpc/soft-float/Dist: Add sim-full.c, fenv_const.c.
	* sysdeps/powerpc/soft-float/sfp-machine.h: Define
	FP_HANDLE_EXCEPTIONS.
	Define FP_ROUNDMODE.
	Redefine FP_* macros to correspond to the FE_* bit positions.
	Define FP_DIV_MEAT_S to _FP_DIV_MEAT_1_loop.
	Define externs for __sim_exceptions, __sim_disabled_exceptions,
	__sim_round_mode, __simulate_exceptions.
	* sysdeps/powerpc/fpu/bits/fenv.h: Move file from here...

2002-10-06  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/powerpc32/dl-machine.c (__process_machine_rela):
	Store R_PPC_UADDR32 and R_PPC_UADDR16 one byte at a time.
	Use __builtin_expect for R_PPC_ADDR24 overflow check.  Fix
	R_PPC_ADDR16, R_PPC_UADDR16 and R_PPC_ADDR14* overflow check, use
	__builtin_expect.
