Hi,

Please find attached the "v850-binutils-v850e2-v850e2v3-support.patch".
The patch adds support for new target variants of V850 i.e. V850E2 and
V850E2V3. These processors are upwardly compatible with earlier V850
targets already supported in the current binutils port. V850E2V3 target
supports floating point operations. Hence, these instructions along with 
registers supported by V850E2V3 are defined in the current patch.

The GCC and Newlib part of the support will be posted in respective
mailing list. The GDB support will also be posted. 

Please review the patch and let me know if there should be any 
modifications in it.
