Direct access to low/high register for 64-bit llong in inline-assembly

Hi, I would like to run the following function for saturation controlled 64-bit-addition to inline assembly: __asm LLONG qadd_ll( LLONG a, LLONG b) { ADDS R0, R0, R2 ADCS R1, R1, R3 BVS Oflw_qadd_ll...

address of struct member

The following code compiles fine with C V7.20 struct { struct { char a; } t; } b; void main(void) { b.t.a=0; (&b)->t.a=0; (&(b.t))->a=0; (*) } and gives an error with V8.05a for line...
