Hi all,

I want ARM cross compiler to emit assembly for add with carry (ADC) and 
saturation add (QADD). what should be the testcase in 'C' for this.

I too tried many, but no one emitted.

Regards,
Rajiv

If you want to ensure that exactly these instructions are used, the 
simplest way would be to put them into your code as inline assembler.
