__builtin_mulss<br />
Built-in Functions<br />
Argument: p0 multiplic<strong>and</strong><br />
p1 multiplier<br />
Return Value: Returns the signed long integer value of the product p0 x p1.<br />
Assembler Operator<br />
/ Machine<br />
Instruction:<br />
mul.ss<br />
__builtin_mulsu<br />
Description: Computes the product p0 x p1. Function arguments are integers with<br />
mixed signs, <strong>and</strong> the function result is a signed long integer. The comm<strong>and</strong>-line<br />
option -Wconversions can be used to detect unexpected<br />
sign conversions. This function supports the full range of addressing<br />
modes of the instruction, including immediate mode <strong>for</strong> oper<strong>and</strong> p1.<br />
Prototype: signed long __builtin_mulsu(const signed int p0,<br />
const unsigned int p1);<br />
Argument: p0 multiplic<strong>and</strong><br />
p1 multiplier<br />
Return Value: Returns the signed long integer value of the product p0 x p1.<br />
