AMCC-440EP floating point error

Hmm... I had tried --without-fp, which is the default for 440 in crosstool, 
before posted a message to the list and crosstool had managed to create a 
cross toolchain... Below is the default content of 440.dat file:

TARGET=powerpc-440-linux-gnu
TARGET_CFLAGS="-O -mcpu=440"
GCC_EXTRA_CONFIG="--with-cpu=440 --enable-cxx-flags=-mcpu=440"
GLIBC_EXTRA_CONFIG="--without-fp"

So far so everything was OK...

But 440EP has hard floating point support and I wanted to use it so I omitted 
the GLIBC_EXTRA_CONFIG because glibc uses hard floating point as default. 
Besides I added GLIBC_EXTRA_CONFIG=”-mhard-float” as an extra precaution. Now 
the contents are

TARGET=powerpc-440-linux-gnu
TARGET_CFLAGS="-O -mcpu=440"
GCC_EXTRA_CONFIG="--with-cpu=440 --enable-cxx-flags=-mcpu=440"
GLIBC_EXTRA_CONFIG=”-mhard-float”

When I use this config I am getting error messages...

After reading your message, then I thought perhaps I should change cpu type 
because not every 440 cpu has a hard FPU. The new 440.dat file content:

TARGET=powerpc-440-linux-gnu
TARGET_CFLAGS="-O -mcpu=440"
GCC_EXTRA_CONFIG="--with-cpu=440fp --enable-cxx-flags=-mcpu=440fp"
GLIBC_EXTRA_CONFIG=”-mhard-float”

Then again I got the same error message. Perhaps I should specify 440fp in 
another form like -march?

Thanks...
