This intrinsic inserts a QSUB
instruction or an equivalent code
sequence into the instruction stream generated by the compiler.
It enables you to obtain the saturating subtraction of two integers
from within your C or C++ code.
int __qsub(intval1
, intval2
)
Where:
val1
is the minuend of the saturating subtraction operation
val2
is the subtrahend of the saturating subtraction operation.
