math.Atan implementation

[rhiro]

I'd like to see the implementation for math.Atan, but I see that https://golang.org/src/math/atan.go seems to be a missing body for that function "func Atan(x float64) float64".  Is this code being hidden, or is there some other mechanism preventing it from showing up?  Thanks.

Atan is implemented in assembly. for amd64 it's just a call to atan
(lowercase a): https://golang.org/src/math/atan_amd64.s

for 386 it is not: https://golang.org/src/math/atan_386.s
