Thanks Ian.

Also it has been mentioned in the gcc/config/rs6000/rs6000.c that "A
happy side-effect is that  '-mno-eabi' libraries can be used with
'-meabi' programs". i also see the 'newlib' built with '-mno-eabi'
option.

Is using 'mno-eabi' libs with 'meabi' program conforms to ABI standard?

Thanks,
