Hi Khem,

Yes, if we use EABI toolchain, the result is always fine regardless of
xscale or iwmmxt.
You mean iwmmxt has its own ABI, which ABI does iwmmxt follow? Are
there documents for iwmmxt like BSABI (ABI for ARM Architecture)?

Thanks and Best regards,
Bridge

Hi Bridge

I think there should be no differences in calling convention if you are
configuring toolchain with EABI.
with Old ABI there may be differences because iwmmxt has it  own  ABI
which was  different.

Thanks

Khem
