executable itself. Keeping cmd/link simple means we cannot possibly
implement the full semantics of the host linker, so the kinds of
objects that can be linked directly into the binary is limited (other
code can only be used as a dynamic library). On the other hand, when
using internal linking, cmd/link can generate Go binaries by itself.

The last instruction in a <code>TEXT</code> block must be some sort of jump, usually a <code>RET</code> (pseudo-)instruction.
(If it's not, the linker will append a jump-to-itself instruction; there is no fallthrough in <code>TEXTs</code>.)
After the symbol, the arguments are flags (see below)
and the frame size, a constant (but see below):
