V2SF will be created by the line
VECTOR_MODES (FLOAT, 8);
Yes you are absolutely right.When i changed the name of file
ABC-modes.def to 1ABC-modes.def ,i got the following error
make[1]: *** No rule to make target
`../../gcc-4.1.0/gcc/config/ABC/ABC-modes.def', needed by
`build/genmodes.o'. Stop.
This shows that ABC-modes.def is being used and it has the required macro
VECTOR_MODES (FLOAT, 8);
Then why still the following error is being generated.
> ../../gcc-4.1.0/gcc/config/ABC/ABC.md: unknown mode `V2SF'
As far as my changes to ABC.md file are concerned .They are as fellows
(define_mode_macro ANYF [(SF "TARGET_HARD_FLOAT")
(DF "TARGET_HARD_FLOAT && TARGET_DOUBLE_FLOAT")])
;; (V2SF "TARGET_PAIRED_SINGLE_FLOAT")])
- - - - - -- - - - - - - - - -
-- - - - - - - - - -- - - - -
(define_mode_attr divide_condition
[DF (SF "!TARGET_FIX_SB1 || flag_unsafe_math_optimizations")])
;; (V2SF "TARGET_SB1 && (!TARGET_FIX_SB1 ||
flag_unsafe_math_optimizations)")])
As you can see i just omitted the entries of V2SF.

V2SF should normally be defined by ABC/ABC-modes.def. It is normally
found by these lines in config.gcc when you run configure:
if test -f ${srcdir}/config/${cpu_type}/${cpu_type}-modes.def
then
extra_modes=${cpu_type}/${cpu_type}-modes.def
fi
V2SF will be created by the line
VECTOR_MODES (FLOAT, 8);
in ABC-modes.def (as copied from mips-modes.def).

Hard to say without knowing what you changed. Did you simply delete
the ANYF macro, or forget to remove the V2SF case from it?
