28.2.38 __builtin_mulss

Description

Computes the product p0 x p1. Function arguments are signed integers, and the function result is a signed long integer. The command-line option -Wconversions can be used to detect unexpected sign conversions.

For example:

 volatile register int a asm("A");
 signed long result;
 const signed int p0, p1;
 const unsigned int p2, p3;
 result = __builtin_mulss(p0,p1);
 a = __builtin_mulss(p0,p1);

Prototype

signed long __builtin_mulss(const signed int p0, const signed int p1);

Argument

p0 – multiplicand

p1 – multiplier

Return Value

Returns the signed long integer value of the product p0 x p1. The value can either be returned into a variable of type signed long or directly into an accumulator register.
