21	It looks at the rtl code for a function and outputs assembler code.

23	Call `final_start_function' to output the assembler code for function entry,

25	`final_end_function' to output assembler code for function exit.
26	If a function is compiled in several pieces, each piece is
27	output separately with `final'.
28
29	Some optimizations are also done at this level.
30	Move instructions that were made unnecessary by good register allocation
31	are detected and omitted from the output. (Though most of these
32	are removed by the last jump pass.)

35	seen that the condition codes already had the desired values.
36
37	In some cases it is sufficient if the inherited condition codes
38	have related values, but this may require the following insn

412
413	Call a sequence of instructions beginning with alignment point X

415	is used in an expression, it means the alignment value of the
416	alignment point.
417
418	Call the distance between the start of the first insn of block X, and
419	the end of the last insn of block X `IX', for the `inner size of X'.
420	This is clearly the sum of the instruction lengths.
421
422	Likewise with the next alignment-delimited block following X, which we
423	shall call block Y.
424
425	Call the distance between the start of the first insn of block X, and
426	the start of the first insn of block Y `OX', for the `outer size of X'.
427
428	The estimated padding is then OX - IX.
429
430	OX can be safely estimated as
431
432	if (X >= Y)
433	OX = round_up(IX, Y)
434	else
435	OX = round_up(IX, X) + Y - X
436
437	Clearly est(IX) >= real(IX), because that only depends on the
438	instruction lengths, and those being overestimated is a given.
439
440	Clearly round_up(foo, Z) >= round_up(bar, Z) if foo >= bar, so
441	we needn't worry about that when thinking about OX.
442
443	When X >= Y, the alignment provided by Y adds no uncertainty factor
444	for branch ranges starting before X, so we can just round what we have.
445	But when X < Y, we don't know anything about the, so to speak,
446	`middle bits', so we have to assume the worst when aligning up from an
447	address mod X to one mod Y, which is Y - X. */
