Quoting Kaz Kojima :
I've got some regressions with "make check" on sh4-unknown-linux-gnu.
It looks that all of them are failed with the undefined references to
__unorddf2/__unordsf2 when -mieee enabled.
That's a bug, then; we shouldn't use a library function there,
but the cmpordered[sd]f_t_4

There are a few warnings in bootstrap:
../trunk/gcc/config/sh/sh.c: In function 'sh_soft_fp_cmp':

Hello,
Back in 2001, GCC could disambiguate almost no MEMs on ia64 because
ia64 has no (reg+offs) addressing modes. Bernd added a trick to alias
and to sched-ebb to use cselib, to substitute a reg address with a
reg+offs address recorded by cselib (see

Hi,
You mean I should define insn like this:
(define_insn "*iorqi3_imm"
[(set (mem:QI (match_operand:HI 0 "register_operand" "b"))
(ior:QI (mem:QI (match_operand:HI 1 "register_operand" "b")
(mem:QI (plus: HI (match_operand:HI 2 "register_operand"
"f")
Hi Kaz,

BTW, it looks that softfp __unord?f2 routines check signaling NaNs
only. This makes __builtin_isnan return false for quiet NaNs for
which current fp-bit ones return true when -mieee enabled. Perhaps
that change of behavior might be OK for software FP.
