155 <a href="/pkg/regexp/">regexp</a> package's unit tests. To build the binary,
156 change to <code>$GOROOT/src/regexp</code> and run <code>go test -c</code>.
157 This should produce an executable file named <code>regexp.test</code>.

240 package is known to GDB as <code>'regexp.Compile'</code>.
245 the <code>*Regexp</code> type?s <code>String</code> method is known as
246 <code>'regexp.(*Regexp).String'</code>.

454 GDB's pretty printing mechanism is triggered by regexp matches on type names. An example for slices:
495 Interfaces are represented in the runtime as a pointer to a type descriptor and a pointer to a value. The Go GDB runtime extension decodes this and automatically triggers pretty printing for the runtime type. The extension function <code>$dtype</code> decodes the dynamic type for you (examples are taken from a breakpoint at <code>regexp.go</code> line 293.)
