/* This is the final pass of the compiler.
|
|
|
|
|
It looks at the rtl code for a function and outputs assembler code.
|
|
|
|
|
|
|
|
|
|
Call `final_start_function' to output the assembler code for function entry,
|
|
|
|
|
`final' to output assembler code for some RTL code,
|
|
|
|
|
`final_end_function' to output assembler code for function exit.
|
|
|
|
|
If a function is compiled in several pieces, each piece is
|
|
|
|
|
output separately with `final'.
|
|
|
|
|
|
|
|
|
|
Some optimizations are also done at this level.
|
|
|
|
|
Move instructions that were made unnecessary by good register allocation
|
|
|
|
|
are detected and omitted from the output. (Though most of these
|
|
|
|
|
are removed by the last jump pass.)
|
|
|
|
|
|
|
|
|
|
Instructions to set the condition codes are omitted when it can be
|
|
|
|
|
seen that the condition codes already had the desired values.
|
|
|
|
|
|
|
|
|
|
In some cases it is sufficient if the inherited condition codes
|
|
|
|
|
have related values, but this may require the following insn
|
|
|
|
|
(the one that tests the condition codes) to be modified.
|
|
|
|
|
|
|
|
|
|
The code for the function prologue and epilogue are generated
|
|
|
|
|
directly as assembler code by the macros FUNCTION_PROLOGUE and
|
|
|
|
|
FUNCTION_EPILOGUE. Those instructions never exist as rtl. */

/* Here is an explanation how the algorithm in align_fuzz can give
|
|
|
|
|
proper results:
|
|
|
|
|
|
|
|
|
|
Call a sequence of instructions beginning with alignment point X
|
|
|
|
|
and continuing until the next alignment point `block X'. When `X'
|
|
|
|
|
is used in an expression, it means the alignment value of the
|
|
|
|
|
alignment point.
|
|
|
|
|
|
|
|
|
|
Call the distance between the start of the first insn of block X, and
|
|
|
|
|
the end of the last insn of block X `IX', for the `inner size of X'.
|
|
|
|
|
This is clearly the sum of the instruction lengths.
|
|
|
|
|
|
|
|
|
|
Likewise with the next alignment-delimited block following X, which we
|
|
|
|
|
shall call block Y.
|
|
|
|
|
|
|
|
|
|
Call the distance between the start of the first insn of block X, and
|
|
|
|
|
the start of the first insn of block Y `OX', for the `outer size of X'.
|
|
|
|
|
|
|
|
|
|
The estimated padding is then OX - IX.
|
|
|
|
|
|
|
|
|
|
OX can be safely estimated as
|
|
|
|
|
|
|
|
|
|
if (X >= Y)
|
|
|
|
|
OX = round_up(IX, Y)
|
|
|
|
|
else
|
|
|
|
|
OX = round_up(IX, X) + Y - X
|
|
|
|
|
|
|
|
|
|
Clearly est(IX) >= real(IX), because that only depends on the
|
|
|
|
|
instruction lengths, and those being overestimated is a given.
|
|
|
|
|
|
|
|
|
|
Clearly round_up(foo, Z) >= round_up(bar, Z) if foo >= bar, so
|
|
|
|
|
we needn't worry about that when thinking about OX.
|
|
|
|
|
|
|
|
|
|
When X >= Y, the alignment provided by Y adds no uncertainty factor
|
|
|
|
|
for branch ranges starting before X, so we can just round what we have.
|
|
|
|
|
But when X < Y, we don't know anything about the, so to speak,
|
|
|
|
|
`middle bits', so we have to assume the worst when aligning up from an
|
|
|
|
|
address mod X to one mod Y, which is Y - X. */

up on, and that is at least as large as the actual difference.

The function align_fuzz calculates the amount we have to add to the

naively computed difference, by traversing the part of the alignment

|
|
|
|
chain of the start insn of the range that is in front of the end insn

that it might contribute to a size increase.

address difference, in case a machine description wants to introduce

|
|
|
|
some common offset that is added to all offsets in a table.
