|
|
issued next.

|
|
|
|
|
|
|
|
TARGET_SCHED_REORDER2: If the register pressure is high, indicate to

|
|
|
TARGET_SCHED_DFA_NEW_CYCLE to skip cycles.

|
|
|
|
|
|
|
|
|
TARGET_SCHED_VARIABLE_ISSUE: Cache the value of can_issue_more so that it
|
|
|
|
|
can be returned from TARGET_SCHED_REORDER2.
|

|
instruction must be less than 1k in front of the instruction. This
|
1995-04-21 03:19:27 +02:00
|
|
|
|
means that we often have to dump a constant inside a function, and
|
|
|
|
|
generate code to branch around it.
|

It is important to minimize this, since the branches will slow things
|
|
|
|
|
down and make things bigger.
|
|
|
|
|
|
|
|
|
|
Worst case code looks like:
|
|
|
|
|
|
|
|
|
|
mov.l L1,rn
|
|
|
|
|
bra L2
|
|
|
|
|
nop
|
|
|
|
|
align
|
|
|
|
|
L1: .long value
|
|
|
|
|
L2:
|
|
|
|
|
..
|
|
|
|
|
|
|
|
|
|
mov.l L3,rn
|
|
|
|
|
bra L4
|
|
|
|
|
nop
|
|
|
|
|
align
|
|
|
|
|
L3: .long value
|
|
|
|
|
L4:
|
|
|
|
|
..
|
|
|
|
|
|
|
|
|
|
We fix this by performing a scan before scheduling, which notices which
|
|
|
|
|
instructions need to have their operands fetched from the constant table
|
|
|
|
|
and builds the table.
|
|
|
|
|
|
|
|
|
|
The algorithm is:
|
|
|
|
|
|
|
|
|
|
scan, find an instruction which needs a pcrel move. Look forward, find the
|
|
|
|
|
last barrier which is within MAX_COUNT bytes of the requirement.
|
|
|
|
|
If there isn't one, make one. Process all the instructions between
|
|
|
|
|
the find and the barrier.
|
|
|
|
|
|
|
|
|
|
In the above example, we can tell that L3 is within 1k of L1, so
|
|
|
|
|
the first move can be shrunk from the 3 insn+constant sequence into
|
|
|
|
|
just 1 insn, and the constant moved to L3 to make:
|
|
|
|
|
|
|
|
|
|
mov.l L1,rn
|
|
|
|
|
..
|
|
|
|
|
mov.l L3,rn
|
|
|
|
|
bra L4
|
|
|
|
|
nop
|
|
|
|
|
align
|
|
|
|
|
L3:.long value
|
|
|
|
|
L4:.long value
|
|
|
|
|
|
|
|
|
|
Then the second move becomes the target for the shortening process. */

prologue / epilogue / warning patches:
2003-07-16 J"orn Rennecke <joern.rennecke@superh.com>
Con Bradley <con.bradley@superh.com>
* sh-protos.h (sh_get_pr_initial_val): Declare.
* sh.c (regno_reg_class): Make its elements type enum reg_class.
(output_stack_adjust): Remove emit_fn argument. Add epilogue_p
and live_regs_mask arguments. Changed all callers.
(save_schedule_s): New structure.
(save_schedule): New typedef.
(scavenge_reg, sh5_schedule_saves, sh5_schedule_saves): New functions.
(calc_live_regs): For TARGET_SHMEDIA, use leaf_function_p.
In interrupts handlers, also save registers that are usually
partially saved, and make sure there is at least one general purpose
register saved if a target register needs saving.
Add casts in comparisons to avoid warnings.
(sh_media_register_for_return): return -1 for interrupt handlers.
(MAX_SAVED_REGS, MAX_TEMPS): New defines.
(sh_expand_prologue): Use sh5_schedule_saves. Check that any temp
registers used are available.
Set RTX_FRAME_RELATED_P where appropriate.
Add an REG_FRAME_RELATED_EXPR for r0 + offset addressing.

r5 have been reserved as fixed registers or assigned

as global registers, and they change during an

interrupt. There are possible ways to handle this:
|
|
|
|
|
|
|
|
|
|
- If we are adjusting the frame pointer (r14), we can do
|
|
|
|
|
with a single temp register and an ordinary push / pop
|
|
|
|
|
on the stack.
|
|
|
|
|
- Grab any call-used or call-saved registers (i.e. not
|
|
|
|
|
fixed or globals) for the temps we need. We might
|
|
|
|
|
also grab r14 if we are adjusting the stack pointer.
|
|
|
|
|
If we can't find enough available registers, issue
|
|
|
|
|
a diagnostic and die - the user must have reserved
|
|
|
|
|
way too many registers.
|
|
|
|
|
But since all this is rather unlikely to happen and
|
|
|
|
|
would require extra testing, we just die if r4 / r5

are not available. */

when there are some intervening statements setting the same register.
|
|
|
|
|
If we did nothing about this, this would hurt the precision switching
|
|
|
|
|
for SH4 badly. There is some cse after reload, but it is unable to
|
|
|
|
|
undo the extra register pressure from the unused instructions, and
|
|
|
|
|
it cannot remove auto-increment loads.
|
|
|
|
|
|
|
|
|
|
A C code example that shows this flow/cse weakness for (at least) SH
|
|
|
|
|
and sparc (as of gcc ss-970706) is this:
|
|
|
|
|
|
|
|
|
|
double
|
|
|
|
|
f(double a)
|
|
|
|
|
{
|
|
|
|
|
double d;
|
|
|
|
|
d = 0.1;
|
|
|
|
|
a += d;
|
|
|
|
|
d = 1.1;
|
|
|
|
|
d = 0.1;
|
|
|
|
|
a *= d;
|
|
|
|
|
return a;
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
So we add another pass before common subexpression elimination, to
|
|
|
|
|
remove assignments that are dead due to a following assignment in the
|
|
|
|
|
same basic block. */

register to a pseudo and using that register, the return value is not

the middle. */
