This patch simplifies the alignment calculations in pad_below.
The first arm of the "if" was:
- taking GET_MODE_BITSIZE (always equal to GET_MODE_SIZE * BITS_PER_UNIT),
- rounding up to the next multiple of PARM_BOUNDARY
- converting bits to bytes and
- subtracting the GET_MODE_SIZE
so was in effect calculating the number of bytes needed to round
GET_MODE_SIZE up to (PARM_BOUNDARY / BITS_PER_UNIT). That can be
done more directly as -size & (align - 1), which is easier to
convert to variable-sized modes.

The previous code processed the users of a stack slot in order of
decreasing size and allocated the slot based on the first user.
This seems a bit dangerous, since the ordering is based on the
mode of the biggest reference while the allocation is based also
on the size of the register itself (which I think could be larger).
That scheme doesn't scale well to polynomial sizes, since there's
no guarantee that the order of the sizes is known at compile time.
This patch instead records an upper bound on the size required
by all users of a slot. It also records the maximum alignment
requirement.

stores together, so insn 310 is moved up past 300 to go together with
some other store). But the REG_CFA_RESTORE and REG_CFA_OFFSET cannot be

PR77962 shows Go failing on 32-bit x86. This happens because the i386
port requires the split stack prologue to be created before the normal
prologue, and my previous patch changed it to be the other way around.
This patch changes it back. Things will be exactly as before for targets
that do not do shrink-wrapping for separate components. For targets
that *do* support it, all three prologue/epilogue creation functions
will now be called twice for functions that have anything wrapped
separately (instead of just the prologue created twice).

This is the main substance of this patch series.
Instead of doing all of the prologue and epilogue in one spot, it often
is better to do components of it at different places, so that they are
executed less frequently.
What exactly is a component is completely up to the target; this code
treats it all abstractly, and uses hooks for the target to handle the
more concrete things. Commonly there is one component for each callee-
saved register, for example.
Components can be executed more than once per function execution. This
pass makes sure that a component's epilogue is not called more often
than the corresponding prologue has been, at any point in time; that the
prologue is called more often, wherever the prologue's effect is needed;
and that the epilogue is called as often as the prologue has been, when
the function exits. It does this by first deciding which blocks need
which components active, and then placing prologue and epilogue
components to make that exactly true.
Deciding what blocks should run with a certain component active so that
the total cost of executing the prologues (and epilogues) is optimal, is
not a computationally feasible problem. Instead, for each basic block,
we estimate the cost of putting a prologue right before the block, and
if that is cheaper than the total cost of putting prologues optimally
(according to the estimated cost) in the dominator subtrees strictly
dominated by this first block, place it at the first block instead.
This simple procedure places the components optimally for any dominator
sub tree where the root node's cost does not depend on anything outside
its subtree.
The cost is the execution frequency of all edges into the block coming
from blocks that do not have this component active. The estimated cost
is the execution frequency of the block, minus the execution frequency
of any backedges (which by definition are coming from subtrees, so if
the "head" block gets a prologue, the source block of any backedge has
that component active as well).
Currently, the epilogues are placed as late as possible, given the
constraints. This does not matter for execution cost, but we could
save a little bit of code size by placing the epilogues in a smarter
way. This is a possible future optimisation.
Now all that is left is inserting prologues and epilogues on all edges
that jump into resp. out of the "active" set of blocks. Often we need
to insert some components' prologues (or epilogues) on all edges into
(or out of) a block. In theory cross-jumping can unify all such, but
in practice that often fails; besides, that is a lot of work. So in
this case we insert the prologue and epilogue components at the "head"
or "tail" of a block, instead.
As a final optimisation, if a block needs a prologue and its immediate
dominator has the block as a post-dominator, that immediate dominator
gets the prologue as well.

On x86, interrupt handlers are only called by processors which push
interrupt data onto stack at the address where the normal return address
is. Since interrupt handlers must access interrupt data via pointers so
that they can update interrupt data, the pointer argument is passed as
"argument pointer - word".
TARGET_FUNCTION_INCOMING_ARG defines how callee sees its argument.
Normally it returns REG, NULL, or CONST_INT. This patch adds arbitrary
address computation based on hard register, which can be forced into a
register, to the list.
When copying an incoming argument onto stack, assign_parm_setup_stack
has:
if (argument in memory)
copy argument in memory to stack
else
move argument to stack
Since an arbitrary address computation may be passed as an argument, we
change it to:
if (argument in memory)
copy argument in memory to stack
else
{
if (argument isn't in register)
force argument into a register
move argument to stack
}
* function.c (assign_parm_setup_stack): Force source into a
register if needed.
* target.def (function_incoming_arg): Update documentation to
allow arbitrary address computation based on hard register.
* doc/tm.texi: Regenerated.

Storing a register in memory as a full word and then accessing the
same memory address under a smaller-than-word mode amounts to
right-shifting of the register word on big endian machines. So, if
BLOCK_REG_PADDING chooses upward padding for BYTES_BIG_ENDIAN, and
we're copying from the entry_parm REG directly to a pseudo, bypassing
any stack slot, perform the shifting explicitly.
This fixes the miscompile of function_return_val_10 in
gcc.target/aarch64/aapcs64/func-ret-4.c for target aarch64_be-elf
introduced in the first patch for 67753.

In assign_parms_setup_block, the copy of args in PARALLELs from
entry_parm to stack_parm is deferred to the parm conversion insn seq,
but the copy from stack_parm to target_reg was inserted in the normal
copy seq, that is executed before the conversion insn seq. Oops.
We could do away with the need for an actual stack_parm in general,
which would have avoided the need for emitting the copy to target_reg
in the conversion seq, but at least on pa, due to the need for stack
to copy between SI and SF modes, it seems like using the reserved
stack slot is beneficial, so I put in logic to use a pre-reserved
stack slot when there is one, and emit the copy to target_reg in the
conversion seq if stack_parm was set up there.

Revert the fragile and complicated changes to assign_parms designed to
enable it to use RTL assigments chosen by cfgexpand, and instead have
cfgexpand use the RTL assignments by assign_parms, keying them off of
the default defs that are now necessarily introduced for each parm and
result. The possible lack of a default def was already a problem, and
the fallbacks in place were not enough, as shown by PR67312. We now
have checking asserts in set_rtl that verify that we're assigning to
each var a piece of RTL that matches the expectations set forth by
use_register_for_decl.

The caller of try_shrink_wrapping wants to be returned a single edge to
put the prologue on. To make that work even if there are multiple edges
(all pointing to the PRO block) that need the prologue, add a new block
that becomes the destination of all such edges, and then jumps to PRO.
In the general case, some edges to PRO will need to be redirected, and
not all edges *can* be redirected. This adds a can_get_prologue function
that detects such cases. This then happily can also handle the "prologue
clobbers some reg that is live on the edge we want to insert it on" case.
Not all EDGE_CROSSING edges can be redirected, so handle those the same
as EDGE_COMPLEX edges.

optabs.[hc] is a bit of a behemoth. It includes basic functions for querying
what a target can do, related tree- and gimple-level query functions,
related rtl-level query functions, and the functions that actually
generate code. Some gimple optimisations therefore need:
#include "insn-config.h"
#include "expmed.h"
#include "dojump.h"
#include "explow.h"
#include "emit-rtl.h"
#include "varasm.h"
#include "stmt.h"
#include "expr.h"
purely to query whether the target has support for a particular operation.
This patch splits optabs up as follows:
- optabs-query.[hc]: IL-independent functions for querying what a target
can do natively.
- optabs-tree.[hc]: tree and gimple query functions (an extension of
optabs-query.[hc]).
- optabs-libfuncs.[hc]: optabs-specific libfuncs (an extension of
libfuncs.h)
- optabs.h: For now includes optabs-query.h and optabs-libfuncs.h.
Only two files outside optabs need to include both optabs.h and
optabs-tree.h: expr.c and function.c. I think that's expected given
that both are related to expand.
It might be good to split optabs.h further, but this is already quite
a big patch.
I changed can_conditionally_move_p from returning an int to returning
a bool and fixed a few formatting glitches. There should be no other
changes to the functions themselves.
