By the time peephole optimizations run, we've already made up our mind
whether to use base-register or relative addressing for literal pool
entries. LT(G) supports only base-register addressing, and so it is
too late to convert L(G)RL + compare to LT(G). This change should not
make the code worse unless building with e.g. -fno-dce, since comparing
literal pool entries to zero should be optimized away during earlier
passes.

r254296 added support for (const ...) wrappers around vectors,
but in the end the agreement was to use a variable-length
encoding of CONST_VECTOR (and VECTOR_CST) instead. This patch
therefore reverts the bits that are no longer needed.
The rtl.texi part isn't a full revert, since r254296 also updated the
documentation to mention unspecs in address calculations, and to relax
the requirement that the mode had to be Pmode.

This patch makes CONST_VECTOR use the same encoding as VECTOR_CST.
One problem that occurs in RTL but not at the tree level is that a fair
amount of code uses XVEC and XVECEXP directly on CONST_VECTORs (which is
valid, just with looser checking). This is complicated by the fact that
vectors are also represented as PARALLELs in some target interfaces,
so using XVECEXP is a good polymorphic way of handling both forms.
Rather than try to untangle all that, the best approach seemed to be to
continue to encode every element in a fixed-length vector. That way only
target-independent and AArch64 code need to be precise about using
CONST_VECTOR_ELT over XVECEXP.
After this change is no longer valid to modify CONST_VECTORs in-place.
This needed some fix-up in the powerpc backends.

This patch makes operand_subword and operand_subword_force take
polynomial offsets. This is a fairly old-school interface and
these days should only be used when splitting multiword operations
into word operations. It still doesn't hurt to support polynomial

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.

Similar to the previous store_bit_field patch, but for extractions
rather than insertions. The patch splits out the extraction-as-subreg
handling into a new function (extract_bit_field_as_subreg), both for
ease of writing and because a later patch will add another caller.
The simplify_gen_subreg overload is temporary; it goes away
in a later patch.

This patch changes the MEM_OFFSET and MEM_SIZE memory attributes
from HOST_WIDE_INT to poly_int64. Most of it is mechanical,
but there is one nonbovious change in widen_memory_access.
Previously the main while loop broke with:
/* Similarly for the decl. */
else if (DECL_P (attrs.expr)
&& DECL_SIZE_UNIT (attrs.expr)
&& TREE_CODE (DECL_SIZE_UNIT (attrs.expr)) == INTEGER_CST
&& compare_tree_int (DECL_SIZE_UNIT (attrs.expr), size) >= 0
&& (! attrs.offset_known_p || attrs.offset >= 0))
break;
but it seemed wrong to optimistically assume the best case
when the offset isn't known (and thus might be negative).
As it happens, the "! attrs.offset_known_p" condition was
always false, because we'd already nullified attrs.expr in
that case:
/* If we don't know what offset we were at within the expression, then
we can't know if we've overstepped the bounds. */
if (! attrs.offset_known_p)
attrs.expr = NULL_TREE;
The patch therefore drops "! attrs.offset_known_p ||" when
converting the offset check to the may/must interface.

This patch changes the type of the reg_attrs offset field
from HOST_WIDE_INT to poly_int64 and updates uses accordingly.
This includes changing reg_attr_hasher::hash to use inchash.
(Doing this has no effect on code generation since the only

This patch adds an rtl representation of poly_int values.
There were three possible ways of doing this:
(1) Add a new rtl code for the poly_ints themselves and store the
coefficients as trailing wide_ints. This would give constants like:
(const_poly_int [c0 c1 ... cn])
The runtime value would be:
c0 + c1 * x1 + ... + cn * xn
(2) Like (1), but use rtxes for the coefficients. This would give
constants like:
(const_poly_int [(const_int c0)
(const_int c1)
...
(const_int cn)])
although the coefficients could be const_wide_ints instead
of const_ints where appropriate.
(3) Add a new rtl code for the polynomial indeterminates,
then use them in const wrappers. A constant like c0 + c1 * x1
would then look like:
(const:M (plus:M (mult:M (const_param:M x1)
(const_int c1))
(const_int c0)))
There didn't seem to be that much to choose between them. The main
advantage of (1) is that it's a more efficient representation and
that we can refer to the cofficients directly as wide_int_storage.

This patch introduces a number of new macros and functions that will
be used to distinguish between different kinds of debug stmts, insns
and notes, namely, preexisting debug bind ones and to-be-introduced
nonbind markers.
In a seemingly mechanical way, it adjusts several uses of the macros
and functions, so that they refer to narrower categories when
appropriate.
These changes, by themselves, should not have any visible effect in
the compiler behavior, since the upcoming debug markers are never
created with this patch alone.

This patch adds a fixed_size_mode machine_mode wrapper
for modes that are known to have a fixed size. That applies
to all current modes, but future patches will add support for
variable-sized modes.
The use of this class should be pretty restricted. One important
use case is to hold the mode of static data, which can never be
variable-sized with current file formats. Another is to hold
the modes of registers involved in __builtin_apply and
__builtin_result, since those interfaces don't cope well with
variable-sized data.
The class can also be useful when reinterpreting the contents of
a fixed-length bit string as a different kind of value.

This patch adds an rtl representation of a vector linear series
of the form:
a[I] = BASE + I * STEP
Like vec_duplicate;
- the new rtx can be used for both constant and non-constant vectors
- when used for constant vectors it is wrapped in a (const ...)
- the constant form is only used for variable-length vectors;
fixed-length vectors still use CONST_VECTOR
At the moment the code is restricted to integer elements, to avoid
concerns over floating-point rounding.

This patch allows (const ...) wrappers to be used for rtx vector
constants, as an alternative to const_vector. This is useful
for SVE, where the number of elements isn't known until runtime.
It could also be useful in future for fixed-length vectors, to
reduce the amount of memory needed to represent simple constants
with high element counts. However, one nice thing about keeping
it restricted to variable-length vectors is that there is never
any need to handle combinations of (const ...) and CONST_VECTOR.

This patch adds a vec_duplicate_p helper that tests for constant
or non-constant vector duplicates. Together with the existing
const_vec_duplicate_p, this complements the gen_vec_duplicate
and gen_const_vec_duplicate added by a previous patch.
The patch uses the new routines to add more rtx simplifications
involving vector duplicates. These mirror simplifications that
we already do for CONST_VECTOR broadcasts and are needed for
variable-length SVE, which uses:
(const:M (vec_duplicate:M X))
to represent constant broadcasts instead. The simplifications do
trigger on the testsuite for variable duplicates too, and in each
case I saw the change was an improvement.
The best way of testing the new simplifications seemed to be
via selftests. The patch cribs part of David's patch here:

This patch adds helper functions that say which of the two modes
involved in a subreg is the larger, preferring the outer mode in
the event of a tie. It also converts IRA and reload to track modes
instead of byte sizes, since this is slightly more convenient when
variable-sized modes are added later.

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 treats the mode associated with an integer constant as a
scalar_mode. We can't use the more natural-sounding scalar_int_mode
because we also use (const_int 0) for bounds-checking modes. (It might
be worth adding a bounds-specific code instead, but that's for another
day.)
This exposes a latent bug in simplify_immed_subreg, which for
vectors of CONST_WIDE_INTs would pass the vector mode rather than
the element mode to rtx_mode_t.
I think the:
/* We can get a 0 for an error mark. */
|| GET_MODE_CLASS (mode) == MODE_VECTOR_INT
|| GET_MODE_CLASS (mode) == MODE_VECTOR_FLOAT
in immed_double_const is dead. trunc_int_mode (via gen_int_mode)
would go on to ICE if the mode fitted in a HWI, and surely plenty
of other code would be confused to see a const_int be interpreted
as a vector. We should instead be using CONST0_RTX (mode) if we
need a safe constant for a particular mode.
We didn't try to make these functions take scalar_mode arguments
because in many cases that would be too invasive at this stage.
Maybe it would become feasible in future. Also, the long-term
direction should probably be to add modes to constant integers
rather than have then as VOIDmode odd-ones-out. That would remove
the need for rtx_mode_t and thus remove the question whether they
should use scalar_int_mode, scalar_mode or machine_mode.
The patch also uses scalar_mode for the CONST_DOUBLE handling
in loc_descriptor. In that case the mode can legitimately be
either floating-point or integral.

This patch adds a helper function to get the mode of the addresses

rtx_jump_table_data over rtx or rtx_insn in cases where it needed
to use the new helper. This in turn meant adding a safe_dyn_cast
equivalent of safe_as_a, to cope with null NEXT_INSNs.

This patch replaces checks of "SCALAR_INT_MODE_P (...)" with
"is_a <scalar_int_mode> (..., &var)" in cases where it becomes
useful to refer to the mode as a scalar_int_mode. It also
replaces some checks for the two constituent classes (MODE_INT

This patch makes more use of the existing paradoxical_subreg_p
predicate and also adds a version that operates on outer and
inner modes.
Some of the affected tests were based on GET_MODE_SIZE rather than
GET_MODE_PRECISION and so the patch could change the result for modes
that have the same size but different precisions. I think in each
case the change should be a no-op or more correct, since a mode with
precision N bits can't be expected to hold all of a mode with precision
M>N bits.
The patch changes the branch taken in simplify_subreg for modes with
equal precision, but the new form matches the commentary more closely.
Both branches should be equally good in that situation.
