This patch changes SUBREG_BYTE from an int to a poly_int.
Since valid SUBREG_BYTEs must be contained within the mode of the
SUBREG_REG, the required range is the same as for GET_MODE_SIZE,
i.e. unsigned short. The patch therefore uses poly_uint16(_pod)
for the SUBREG_BYTE.
Using poly_uint16_pod rtx fields requires a new field code ('p').
Since there are no other uses of 'p' besides SUBREG_BYTE, the patch
doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE
instead.
The patch doesn't bother implementing 'p' support for legacy
define_peepholes, since none of the remaining ones have subregs
in their patterns.
As it happened, the rtl documentation used SUBREG as an example of a
code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1).
Since there's no direct replacement for XINT, and since people should
never use it even if there were, the patch changes the example to use
INT_LIST instead.
The patch also changes subreg-related helper functions so that they too
take and return polynomial offsets. This makes the patch quite big, but
it's mostly mechanical. The patch generally sticks to existing choices
wrt signedness.

This patch adds a helper routine that constructs rtxes
for constant shift amounts, given the mode of the value
being shifted. As well as helping with the SVE patches, this
is one step towards allowing CONST_INTs to have a real mode.
One long-standing problem has been to decide what the mode
of a shift count should be for arbitrary rtxes (as opposed to those
directly tied to a target pattern). Realistic choices would be
the mode of the shifted elements, word_mode, QImode, a 64-bit mode,
or the same mode as the shift optabs (in which case what should the
mode be when the target doesn't have a pattern?)
For now the patch picks a 64-bit mode, but with a ??? comment.

This patch uses subreg_lowpart_offset in places that open-coded
the calculation. It also uses it in regcprop.c to test whether,
after a mode change, the first register in a multi-register group
is still the right one.

The wide_int routines allow things like:
wi::add (t, 1)
to add 1 to an INTEGER_CST T in its native precision. But we also have:
wi::to_offset (t) // Treat T as an offset_int
wi::to_widest (t) // Treat T as a widest_int
Recently we also gained:
wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC
This patch therefore requires:
wi::to_wide (t)
when operating on INTEGER_CSTs in their native precision. This is
just as efficient, and makes it clearer that a deliberate choice is
being made to treat the tree as a wide_int in its native precision.
This also removes the inconsistency that
a) INTEGER_CSTs in their native precision can be used without an accessor
but must use wi:: functions instead of C++ operators
b) the other forms need an explicit accessor but the result can be used
with C++ operators.
It also helps with SVE, where there's the additional possibility
that the tree could be a runtime value.

The tree wi:: decompose routine wasn't asserting that the requested
precision matched the tree's precision. This could make a difference
for unsigned trees that are exactly N HWIs wide and that have the upper
bit set, since we then need an extra zero HWI when extending it to wider
precisions (as for wi::to_widest).
This patch adds the assert and fixes the fallout shown by the testsuite.
Go seems to be unaffected.

This patch replaces various places that previously used:
if (GET_CODE (y) == CONST_INT)
... plus_constant (..., x, [-]INTVAL (y)) ...
else
... gen_rtx_PLUS/MINUS (..., x, y) ...
with single calls to simplify_gen_binary. This allows
them to handle polynomial integers as well as constants.

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.

PR82045 is about a bootstrap failure on sparc-sun-solaris2.11.
The problem was that we were passing the new machine_mode wrapper
classes through "..." to emit_library_call(_value), which then
read them back as ints instead.
The simplest fix seemed to be replace "..." with an array of
rtx_mode_ts, then provide wrappers for the common cases. This
bulks out rtl.h a bit, but it does make things a bit more typesafe.

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.

This patch adds a wrapper around mode_for_size for cases in which
the mode class is MODE_INT (the commonest case). The return type
can then be an opt_scalar_int_mode instead of a machine_mode.

This patch implements support for marking CALL_EXPRs
as being mandatory for tail-call-optimization. expand_call
tries harder to perform the optimization on such CALL_EXPRs,
and issues an error if it fails.
Currently this flag isn't accessible from any frontend,
so the patch uses a plugin for testing the functionality.
