+
+// To test the Breakpad symbol dumper and processor thoroughly, for
+// all combinations of host system and minidump processor
+// architecture, we need to be able to easily generate complex test
+// data like debugging information and minidump files.
+//
+// For example, if we want our unit tests to provide full code
+// coverage for stack walking, it may be difficult to persuade the
+// compiler to generate every possible sort of stack walking
+// information that we want to support; there are probably DWARF CFI
+// opcodes that GCC never emits. Similarly, if we want to test our
+// error handling, we will need to generate damaged minidumps or
+// debugging information that (we hope) the client or compiler will
+// never produce on its own.
+//
+// google_breakpad::TestAssembler provides a predictable and
+// (relatively) simple way to generate complex formatted data streams
+// like minidumps and CFI. Furthermore, because TestAssembler is
+// portable, developers without access to (say) Visual Studio or a
+// SPARC assembler can still work on test data for those targets.

+//
+// A label can be in one of three states:
+// - undefined,

+// - a constant.
+//
+// A label's value never changes, but it can accumulate constraints.
+// Adding labels and integers is permitted, and yields a label.
+// Subtracting a constant from a label is permitted, and also yields a
+// label. Subtracting two labels that have some relationship to each
+// other is permitted, and yields a constant.
+//
+// For example:
+//
+// Label a; // a's value is undefined
+// Label b; // b's value is undefined
+// {
+// Label c = a + 4; // okay, even though a's value is unknown
+// b = c + 4; // also okay; b is now a+8

+// d - a; // is 6, even though their values are not known
+// a = 12; // now b == 20, and d == 18
+// d.Value(); // 18: no longer an error
+// b.Value(); // 20
+// d = 10; // error: d is already defined.
+//
+// Label objects' lifetimes are unconstrained: notice that, in the
+// above example, even though a and b are only related through c, and
+// c goes out of scope, the assignment to a sets b's value as well. In
