I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the
version that was in most header files, since the one in the manual seemed
less clear.
The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in
microblaze_starting_frame_offset; this seems to be a port-local
convention and takes advantage of the fact that FIRST_PARM_OFFSET
doesn't read FNDECL.

I'm not sure the documentation is correct that outprec is always less
than inprec, and each non-default implementation tested for the case
in which it wasn't, but the patch leaves it as-is.
The SH port had a couple of TRULY_NOOP_TRUNCATION tests that were left
over from the old shmedia port.

This patch converts more places that could use int_mode_for_size instead
of mode_for_size. This is in preparation for an upcoming patch that
makes mode_for_size itself return an opt_mode.
require () seems like the right choice in expand_builtin_powi
because we have got past the point of backing out. We go on to do:
op1 = expand_expr (arg1, NULL_RTX, mode2, EXPAND_NORMAL);
if (GET_MODE (op1) != mode2)
op1 = convert_to_mode (mode2, op1, 0);
which would be invalid for (and have failed for) BLKmode.
In get_builtin_sync_mode and expand_ifn_atomic_compare_exchange,
the possible bitsizes are {8, 16, 32, 64, 128}, all of which give
target-independent integer modes (up to TImode). The comment above
the call in get_builtin_sync_mode makes clear that an integer mode
must be found.
We can use require () in expand_builtin_atomic_clear and
expand_builtin_atomic_test_and_set because there's always an integer
mode for the boolean type. The same goes for the POINTER_SIZE request
in layout_type. Similarly we can use require () in combine_instructions
and gen_lowpart_common because there's always an integer mode for
HOST_BITS_PER_WIDE_INT (DImode when BITS_PER_UNIT == 8), and
HOST_BITS_PER_DOUBLE_INT (TImode).
The calls in aarch64_function_value, arm_function_value,
aapcs_allocate_return_reg and mips_function_value_1 are handling
cases in which a big-endian target passes or returns values at
the most significant end of a register. In each case the ABI
constrains the size to a small amount and does not handle
non-power-of-2 sizes wider than a word.
The calls in c6x_expand_movmem, i386.c:emit_memset,
lm32_block_move_inline, microblaze_block_move_straight and
mips_block_move_straight are dealing with expansions of
block memory operations using register-wise operations,
and those registers must have non-BLK mode.
The reason for using require () in ix86_expand_sse_cmp,
mips_expand_ins_as_unaligned_store, spu.c:adjust_operand and
spu_emit_branch_and_set is that we go on to emit non-call
instructions that use registers of that mode, which wouldn't
be valid for BLKmode.

This patch adds a partial_subreg_p predicate to go alongside
paradoxical_subreg_p.
Like the paradoxical_subreg_p patch, this one replaces some tests that
were based on GET_MODE_SIZE rather than GET_MODE_PRECISION. In each
case the change should be a no-op or an improvement.
The regcprop.c patch prevents some replacements of the 82-bit RFmode
with the 80-bit XFmode on ia64. I don't understand the target details
here particularly well, but from the way the modes are described in
ia64-modes.def, it isn't valid to assume that an XFmode can carry an
RFmode payload. A comparison of the testsuite assembly output for one
target per CPU showed no other differences.
Some of the places changed here are tracking the widest access mode
found for a register. The series tries to standardise on:
if (partial_subreg_p (widest_seen, new_mode))
widest_seen = new_mode;
rather than:
if (paradoxical_subreg_p (new_mode, widest_seen))
widest_seen = new_mode;
Either would have been OK.

In expand_divmod, op1 is always a scalar_int_mode if

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.

This patch makes scheduling not reorder prologue insns relative to
epilogue insns and vice versa. This fixes PR78029.
The problem in that PR:
We have two insns, in this order:
(insn/f 300 299 267 8 (set (reg:DI 65 lr)
(reg:DI 0 0)) 579 {*movdi_internal64}
(expr_list:REG_DEAD (reg:DI 0 0)
(expr_list:REG_CFA_RESTORE (reg:DI 65 lr)
(nil))))
...
(insn/f 310 268 134 8 (set (mem/c:DI (plus:DI (reg/f:DI 1 1)
(const_int 144 [0x90])) [6 S8 A8])
(reg:DI 0 0)) 579 {*movdi_internal64}
(expr_list:REG_DEAD (reg:DI 0 0)
(expr_list:REG_CFA_OFFSET (set (mem/c:DI (plus:DI (reg/f:DI 1 1)
(const_int 144 [0x90])) [6 S8 A8])
(reg:DI 65 lr))
(nil))))
and sched swaps them (when compiling for power6, it tries to put memory
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
swapped (they both say where the orig value of LR now lives).

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).
PR bootstrap/77962
* function.c (thread_prologue_and_epilogue_insns): Call all

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.

This patch restructures how the prologues/epilogues are inserted. Sibcalls
that run without prologue are now handled in shrink-wrap.c; it communicates
what is already handled by setting the EDGE_IGNORE flag. The
try_shrink_wrapping function then doesn't need to be passed the bb_flags
anymore.
* function.c (make_epilogue_seq): Remove epilogue_end parameter.
(thread_prologue_and_epilogue_insns): Remove bb_flags. Restructure
code. Ignore sibcalls on EDGE_IGNORE edges.
* shrink-wrap.c (handle_simple_exit): New function. Set EDGE_IGNORE
on edges for sibcalls that run without prologue. The rest of the
function is combined from...
(fix_fake_fallthrough_edge): ... this, and ...
(try_shrink_wrapping): ... a part of this. Remove the bb_with
function argument, make it a local variable.
