| |
| <p><a name="index-Go-_0028programming-language_0029-1014"></a><span class="sc">gdb</span> can be used to debug programs written in Go and compiled with |
| <samp><span class="file">gccgo</span></samp> or <samp><span class="file">6g</span></samp> compilers. |
| |
| <p>Here is a summary of the Go-specific features and restrictions: |
| |
| |
| <a name="index-current-Go-package-1015"></a> |
| <dl><dt><code>The current Go package</code><dd>The name of the current package does not need to be specified when |
| specifying global variables and functions. |
| |
| <p>For example, given the program: |
| |
| <pre class="example"> package main |
| var myglob = "Shall we?" |
| func main () { |
| // ... |
| } |
| </pre> |
| <p>When stopped inside <code>main</code> either of these work: |
| |
| <pre class="example"> (gdb) p myglob |
| (gdb) p main.myglob |
| </pre> |
| <p><a name="index-builtin-Go-types-1016"></a><br><dt><code>Builtin Go types</code><dd>The <code>string</code> type is recognized by <span class="sc">gdb</span> and is printed |
| as a string. |
| |
| <p><a name="index-builtin-Go-functions-1017"></a><br><dt><code>Builtin Go functions</code><dd>The <span class="sc">gdb</span> expression parser recognizes the <code>unsafe.Sizeof</code> |
| function and handles it internally. |
| |
| <p><a name="index-restrictions-on-Go-expressions-1018"></a><br><dt><code>Restrictions on Go expressions</code><dd>All Go operators are supported except <code>&^</code>. |
| The Go <code>_</code> “blank identifier” is not supported. |
| Automatic dereferencing of pointers is not supported. |
