is the --nfp configure option still alive for targets which do not
have an fpu or we can omit this option also for targets without fpu?

The answer is probably "no", but in order to be sure, can say for which
target you want to configure without fpu support ?
Cheers

i glanced through the binutils sources recently and couldnt actually find
anywhere that the option was utilized ...
--nfp sets the 'with_fp' variable to 'no' in all the configure scripts, but
'with_fp' doesnt seem to be checked at any point
ive been doing softfloat arm recently and havent had to do anything different
with binutils to have it work properly compared to hardfloat arm ...

Right, the answer is "no the --nfp switch is not used by binutils for
the PowerPC target (any CPU)". In fact looking at the GCC configure
files as well, it appears that this switch is not used there either.
The reason for the "--nfp is obsolete" comment being present in the
configure files is that it is added there automatically when then
configure file is generated from the configure.in file. The autoconf
program probably does not need to insert this comment any more (or the
lines that handle --nfp) but it is safest to leave them in case someone
has a very old configure command line lying around somewhere.
Cheers
Nick
