gdb: Go
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.
