Update. 2002-10-08 Richard Henderson <rth@redhat.com> * soft-fp/op-4.h: Handle carry correctly in __FP_FRAC_ADD_3, __FP_FRAC_ADD_4, __FP_FRAC_SUB_3, __FP_FRAC_SUB_4, __FP_FRAC_DEC_3, __FP_FRAC_DEC_4. * soft-fp/op-common.h: New macros _FP_DIV_MEAT_N_loop. 2002-10-08 Aldy Hernandez <aldyh@redhat.com> * configure.in: Compute completely-soft. * config.make.in: Make completely-soft available to sub-makes. * sysdeps/powerpc/soft-fp/Makefile: Add gcc-single-routines and gcc-double-routines. Add sim-full.c. Add fenv_const and fe_nomask to libm-support. * sysdeps/powerpc/soft-fp/sim-full.c: New file. * sysdeps/powerpc/soft-fp/fraiseexcpt.c: New file. * sysdeps/powerpc/soft-fp/fegetexcept.c: New file. * sysdeps/powerpc/soft-fp/fclrexcpt.c: New file. * sysdeps/powerpc/soft-fp/ftestexcept.c: New file. * sysdeps/powerpc/soft-fp/fgetexcptflg.c: New file. * sysdeps/powerpc/soft-fp/fsetexcptflg.c: New file. * sysdeps/powerpc/soft-fp/fedisblxcpt.c: New file. * sysdeps/powerpc/soft-fp/feenablxcpt.c: New file. * sysdeps/powerpc/soft-fp/fegetenv.c: New file. * sysdeps/powerpc/soft-fp/fesetenv.c: New file. * sysdeps/powerpc/soft-fp/fegetround.c: New file. * sysdeps/powerpc/soft-fp/fesetround.c: New file. * sysdeps/powerpc/soft-fp/feupdateenv.c: New file. * sysdeps/powerpc/soft-fp/feholdexcpt.c: New file. * sysdeps/powerpc/soft-fp/fenv_const.c: New file. * sysdeps/powerpc/soft-fp/libm-test-ulps: New file. * sysdeps/powerpc/soft-fp/Versions: Add libgcc soft-float symbols.

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... * sysdeps/powerpc/bits/fenv.h: ...to 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.
