#### 15.4.3 Go

gdb can be used to debug programs written in Go and compiled with `gccgo` or `6g` compilers.

Here is a summary of the Go-specific features and restrictions:

`The current Go package`
  The name of the current package does not need to be specified when specifying global variables and functions.

  For example, given the program:

                package main
                var myglob = "Shall we?"
                func main () {
                  // ...
                }

  When stopped inside `main` either of these work:

                (gdb) p myglob
                (gdb) p main.myglob

`Builtin Go types`
  The `string` type is recognized by gdb and is printed as a string.

`Builtin Go functions`
  The gdb expression parser recognizes the `unsafe.Sizeof` function and handles it internally.

`Restrictions on Go expressions`
  All Go operators are supported except `&^`. The Go `_` “blank identifier” is not supported. Automatic dereferencing of pointers is not supported.
