@ -560,16 +560,15 @@ an optional ``unnamed_addr`` attribute, a return type, an optional
name, a possibly empty list of arguments, an optional alignment, an optional
:ref:`garbage collector name <gc>` and an optional :ref:`prefix <prefixdata>`.
A function definition contains a list of basic blocks, forming the CFG
(Control Flow Graph) for the function. Each basic block may optionally
start with a label (giving the basic block a symbol table entry),
contains a list of instructions, and ends with a
:ref:`terminator <terminators>` instruction (such as a branch or function
return). If explicit label is not provided, a block is assigned an
implicit numbered label, using a next value from the same counter as used
for unnamed temporaries (:ref:`see above<identifiers>`). For example, if a
function entry block does not have explicit label, it will be assigned
label "%0", then first unnamed temporary in that block will be "%1", etc.

The first basic block in a function is special in two ways: it is
immediately executed on entrance to the function, and it is not allowed
