Apply compiler directives to avo functions.
The code generator uses the Pragma function to apply the //go:noescape directive to the Add function:
func main() {
TEXT("Add", NOSPLIT, "func(z, x, y *uint64)")
Pragma("noescape")
Doc("Add adds the values at x and y and writes the result to z.")
zptr := Mem{Base: Load(Param("z"), GP64())}
xptr := Mem{Base: Load(Param("x"), GP64())}
yptr := Mem{Base: Load(Param("y"), GP64())}
x, y := GP64(), GP64()
MOVQ(xptr, x)
MOVQ(yptr, y)
ADDQ(x, y)
MOVQ(y, zptr)
RET()
Generate()
}Note the directive is applied in the generated stub file:
// Add adds the values at x and y and writes the result to z.
//
//go:noescape
