Where is append() implementation?

Question

I cannot find implementation code of append() or any other builtin functions anywhere? I tried finding the code through godoc and using jump-to-definition feature of IDE's. May be i am looking at wrong places. Could anyone show me the way to see actual implementation?

If you want to see the builtin API see http://golang.org/src/builtin/builtin.go — Sridhar, Aug 03 '15 at 14:51
Yes it's the API. The source will probably be written in a combination of C/C++/assembly which may also be open source but you'll have to look a little harder. — Sridhar, Aug 03 '15 at 15:15
The source is pretty much all in Go, though part of it is in a hardcore-reading form as that part resides in the code generation package. Details in my answer below. — Mathias Dolidon, Aug 03 '15 at 16:15
You can check out the Append() example in the following link http://blog.golang.org/slices — Rain Lee, Aug 03 '15 at 22:55

You may be interested by :

the code generating bit append is in here https://github.com/golang/go/blob/go1.16.7/src/cmd/compile/internal/gc/ssa.go
and growslice, used by the former, and that lives in here : https://github.com/golang/go/blob/go1.16.7/src/runtime/slice.go
