g:72fbd3b2b2a497dbbe6599239bd61c5624203ed0 added a use of std::array
without explicitly forcing <array> to be included. That didn't cause
problems in my local builds but understandably did for some people.

Currently how we determine which mode will be used for a
floating point type is that for a given type precision
(size) call mode_for_size to get the first mode which has
this size in the specified class. On Powerpc, we have
three modes (TF/KF/IF) having the same mode precision 128
(see[1]), so the processing forces us to have to place TF
at the first place, it would require us to make more
adjustment in some generic code to avoid some unexpected
mode conversions and it would be even worse if we get rid
of TF eventually one day. And as Joseph pointed out in [2],
"floating types should have their mode, not a poorly
defined precision value", as Joseph and Richi suggested,
this patch is to introduce one hook mode_for_floating_type
which returns the corresponding mode for type float, double
or long double. The default implementation returns SFmode
for float and DFmode for double or long double. For ports
which need special treatment, there are some other patches
for their own port specific implementation (referring to
how {,LONG_}DOUBLE_TYPE_SIZE get used there). For all
generic uses of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE, depending
on the context, some of them are replaced with TYPE_PRECISION
of the according type node, some other are replaced with
GET_MODE_PRECISION on the mode from mode_for_floating_type.
This patch also poisons {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE,
so most defines of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE in port
specific are removed, but there are still some which are
good to be kept for readability then they get renamed with
port specific prefix.

rtl-ssa has routines for scanning forwards or backwards for something
under the control of an exclusion set. These searches are currently
used for two main things:
- to work out where an instruction can be moved within its EBB
- to work out whether recog can add a new hard register clobber
The exclusion set was originally a callback function that returned
true for insns that should be ignored. However, for the late-combine
work, I'd also like to be able to skip an entire definition, along
with all its uses.
This patch prepares for that by turning the exclusion set into an
object that provides predicate member functions. Currently the
only two member functions are:
- should_ignore_insn: what the old callback did
- should_ignore_def: the new functionality
but more could be added later.
Doing this also makes it easy to remove some asymmetry that I think
in hindsight was a mistake: in forward scans, ignoring an insn meant
ignoring all definitions in that insn (ok) and all uses of those
definitions (non-obvious). The new interface makes it possible
to select the required behaviour, with that behaviour being applied
consistently in both directions.
Now that the exclusion set is a dedicated object, rather than
just a "random" function, I think it makes sense to remove the
_ignoring suffix from the function names. The suffix was originally
there to describe the callback, and in particular to emphasise that
a true return meant "ignore" rather than "heed".

This patch fixes up the code examples in the RTL-SSA documentation (the
sections on making insn changes) to reflect the current API.
The main issues are as follows:
- rtl_ssa::recog takes an obstack_watermark & as the first parameter.
Presumably this is intended to be the change attempt, so I've updated
the examples to pass this through.
- The variants of recog and restrict_movement that take an ignore
predicate have been renamed with an _ignoring suffix, so I've
updated callers to use those names.
- A couple of minor "obvious" fixes to add a missing address-of
operator and correct a variable name.

An analysis of backend UNSPECs reveals that two of the most common UNSPECs
across target backends are for copysign and bit reversal. This patch
adds RTX codes for these expressions to allow their representation to

This change is a generalization of r13-6292-gddf6fe375d9110.
Historically, makeinfo exhibited a bug, due to which a structure like:
@item foo
@cindex foo
@cindex bar
... would be transformed into an item heading, with the first index
entry on it, followed by an item body, with the second index entry in
it. This has often lead to index entries not linking to relevant items,
but rather, just below them.
This bug was exhibited in both Info and HTML documentation, and was most
glaringly obvious in the latter.
After a discussion with the Texinfo developers, it was decided that the
appropriate construct for this case is:
@cindex foo
@cindex bar
@item foo
... which behaves correctly in newer versions, linking all the index
entries to the item itself. This pattern also produces copiable
anchors in HTML output.
This commit fixes most indices to follow the pattern above, however,
omits relevant changes in the Ada manuals, as the algorithm described
below lead to many false positives and unwanted changes in that manual.
Much like the previous commit, this change is mostly mechanical, with a
simple script. I have, however, gone over the patch myself also, to see
if there's anything that ought to be kept as-is. Formatter:

This patch introduces new RTX codes to allow the RTL passes and
backends to consistently represent high-part multiplications.
Currently, the RTL used by different backends for expanding
smul<mode>3_highpart and umul<mode>3_highpart varies greatly,
with many but not all choosing to express this something like:
(define_insn "smuldi3_highpart"
[(set (match_operand:DI 0 "nvptx_register_operand" "=R")
(truncate:DI
(lshiftrt:TI
(mult:TI (sign_extend:TI
(match_operand:DI 1 "nvptx_register_operand" "R"))
(sign_extend:TI
(match_operand:DI 2 "nvptx_register_operand" "R")))
(const_int 64))))]
""
"%.\\tmul.hi.s64\\t%0, %1, %2;")
One complication with using this "widening multiplication" representation
is that it requires an intermediate in a wider mode, making it difficult
or impossible to encode a high-part multiplication of the widest supported
integer mode. A second is that it can interfere with optimization; for
example simplify-rtx.c contains the comment:
case TRUNCATE:
/* Don't optimize (lshiftrt (mult ...)) as it would interfere
with the umulXi3_highpart patterns. */
Hopefully these problems are solved (or reduced) by introducing a
new canonical form for high-part multiplications in RTL passes.
This also simplifies insn patterns when one operand is constant.
Whilst implementing some constant folding simplifications and
compile-time evaluation of these new RTX codes, I noticed that
this functionality could also be added for the existing saturating
arithmetic RTX codes. Then likewise when documenting these new RTX
codes, I also took the opportunity to silence the @xref warnings in
invoke.texi.

This removes CC0 and all directly related infrastructure.
CC_STATUS, CC_STATUS_MDEP, CC_STATUS_MDEP_INIT, and NOTICE_UPDATE_CC
are deleted and poisoned. CC0 is only deleted (some targets use that
name for something else). HAVE_cc0 is automatically generated, and we
no longer will do that after this patch.
CC_STATUS_INIT is suggested in final.c to also be useful for ports that
are not CC0, and at least arm seems to use it for something. So I am
leaving that alone, but most targets that have it could remove it.

Handle machine mode specification with `const_double_zero' and handle
the rtx with callable code produced from named insns. Complementing
commit 20ab43b5cad6 ("RTL: Add `const_double_zero' syntactic rtx") and
removing a commit c60d0736dff7 ("PDP11: Use `const_double_zero' to
express double zero constant") build regression observed with the
`pdp11-aout' target:

and ultimately `(const_double_zero)' referred in a named RTL insn cannot

The use of a constant double zero is required for post-reload compare
elimination to be able to discard redundant floating-point comparisons,
for example with a VAX RTL instruction stream like:
(insn 34 4 3 2 (parallel [

(mem/c:DF (plus:SI (reg/f:SI 12 %ap)

that we want to transform into:

with the upcoming MODE_CC representation.
For this we need to express the `const_double:DF 0.0 [0x0.0p+0]' rtx as
recorded above in the relevant pattern(s) in machine description. The
way we represent double constants, as a host-dependent number of wide
integers, however means that we currently have no portable way to encode
a double zero constant in machine description.
Define a syntactic rtx alias then to represent `(const_double 0 0 ...)'
as if the suitable number of zeros have been supplied according to the
host-specific definition of CONST_DOUBLE_FORMAT.

After discussion with Richard Sandiford on IRC, he suggested adding a
new mode class MODE_OPAQUE to deal with the problems (PR 96791) we had
been having with POImode/PXImode in powerpc target. This patch is the
accumulation of changes I needed to make to add this and make it useable
for the purposes of what power10 MMA needed.
MODE_OPAQUE modes allow you to have modes for which you can just
define loads and stores. By design, optimization does not expect to
know how to do arithmetic or subregs on these modes. This allows us to
have modes for multi-register vector operations where we don't want to
open Pandora's Box and define general arithmetic operations.
This patch will be followed by a target specific patch to change the
powerpc power10 MMA builtins to use opaque modes, and will also let use
use the vector pair loads/stores defined with that in the inline expansion
of memcpy/memmove, allowing me to fix PR 96791.

The AArch64 SVE tlsdesc patterns were the main motivating reason
for clobber_high. It's no longer needed now that the patterns use
calls instead.
At the time, one of the possible future uses for clobber_high was for
asm statements. However, the current code wouldn't handle that case
without modification, so I think we might as well remove it for now.
We can always reapply it in future if it turns out to be useful again.

The vec_select operator is documented to require a const_int for the lane
selector operand, but GCN has an instruction that can select the lane at
runtime, so it seems reasonable to remove this restriction.
This patch simply replaces assertions that the operand is constant with early
exits from the optimizers. I think it's reasonable that vec_select with a
non-constant operand cannot be optimized, yet.
Also included is the necessary documentation tweak.

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 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 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 adds a new "poly_int" class to represent polynomial integers
of the form:
C0 + C1*X1 + C2*X2 ... + Cn*Xn
It also adds poly_int-based typedefs for offsets and sizes of various
precisions. In these typedefs, the Ci coefficients are compile-time
constants and the Xi indeterminates are run-time invariants. The number
of coefficients is controlled by the target and is initially 1 for all
ports.
Most routines can handle general coefficient counts, but for now a few
are specific to one or two coefficients. Support for other coefficient
counts can be added when needed.
The patch also adds a new macro, IN_TARGET_CODE, that can be
set to indicate that a TU contains target-specific rather than
target-independent code. When this macro is set and the number of
coefficients is 1, the poly-int.h classes define a conversion operator
to a constant. This allows most existing target code to work without
modification. The main exceptions are:
- values passed through ..., which need an explicit conversion to a
constant
- ?: expression in which one arm ends up being a polynomial and the
other remains a constant. In these cases it would be valid to convert
the constant to a polynomial and the polynomial to a constant, so a
cast is needed to break the ambiguity.
The patch also adds a new target hook to return the estimated
value of a polynomial for costing purposes.
The patch also adds operator<< on wide_ints (it was already defined
for offset_int and widest_int). I think this was originally excluded
because >> is ambiguous for wide_int, but << is useful for converting
bytes to bits, etc., so is worth defining on its own. The patch also
adds operator% and operator/ for offset_int and widest_int, since those
types are always signed. These changes allow the poly_int interface to
be more predictable.
I'd originally tried adding the tests as selftests, but that ended up
bloating cc1 by at least a third. It also took a while to build them
at -O2. The patch therefore uses plugin tests instead, where we can
force the tests to be built at -O0. They still run in negligible time
when built that way.

This patch completes the infrastructure for the introduction of
statement frontiers in C-family languages.
It brings in all the code remaining code needed to introduce and
transform begin stmt trees, gimple stmts, insns and notes, and
ultimately use them to generate the is_stmt column in DWARF2+ line
number tables/programs, however none of it is activated: the option
that would do so will be introduced in a subsequent patch.
This patch depends on an earlier patch with not-quite-boilerplate
