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.
