/* 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
|
2001-07-06 20:40:17 +02:00
|
|
|
|
directly in assembler by the target functions function_prologue and
|
|
|
|
|
function_epilogue. Those instructions never exist as rtl. */

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. */
