#### 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.
