My forthcoming patches for PR other/116613 make much more use of
cloning of pretty_printers than before, so it makes sense as a
preliminary patch for the result of pretty_printer::clone to be a
std::unique_ptr, rather than add more manual uses of "delete".
On doing so, I noticed various other places where naked new/delete is
used for run-time configuration of diagnostics:
* the output format (text vs SARIF)
* client data hooks
* the option manager
* the URLifier
Hence this patch also makes use of std::unique_ptr and ::make_unique for
managing such client policy classes, and also for diagnostic_buffer's
per-format implementations.
Unfortunately we can't directly include <memory> in our internal headers
but instead any of our TUs that make use of std::unique_ptr must #define
INCLUDE_MEMORY before including system.h.
Hence the bulk of this patch is taken up with adding a define of
INCLUDE_MEMORY to hundreds of source files: everything that includes
diagnostic.h or pretty-print.h (and thus anything transitively such as
includers of lto-wrapper.h, c-tree.h, cp-tree.h and rtl-ssa.h).
Thanks to Gaius Mulley for the parts of the patch that regenerated the
m2 files.

While working on PR117028 C2Y changes, I've noticed weird ternary
operator formatting (operand1 ? operand2: operand3).
The usual formatting is operand1 ? operand2 : operand3
where we have around 18000+ cases of that (counting only what fits
on one line) and
indent -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2 -ndj \
-nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -psl -nsc -nsob
documented in
https://www.gnu.org/prep/standards/html_node/Formatting.html#Formatting
does the same.
Some code was even trying to save space as much as possible and used
operand1?operand2:operand3 or
operand1 ? operand2:operand3
Today I've grepped for such cases (the grep was '?.*[^ ]:' and I had to
skim through various false positives with that where the : matched e.g.
stuff inside of strings, or *.md pattern macros or :: scope) and the
following patch is a fix for what I found.

This is per the request from the kernel developers. For generating the
ORC unwind info, the objtool program needs to analysis the control flow
of a .o file. If a jump table is used, objtool has to correlate the
jump instruction with the table.
On x86 (where objtool was initially developed) it's simple: a relocation
entry natrually correlates them because one single instruction is used
for table-based jump. But on an RISC machine objtool would have to
reconstruct the data flow if it must find out the correlation on its
own.
So, emit an additional section to store the correlation info as pairs of
addresses, each pair contains the address of a jump instruction (jr) and
the address of the jump table. This is very trivial to implement in
GCC.

Per a gcc-help thread we are generating sub-optimal code for
__builtin_bswap{32,64}. To fix it:
- Use a single revb.d instruction for bswapdi2.
- Use a single revb.2w instruction for bswapsi2 for TARGET_64BIT,
revb.2h + rotri.w for !TARGET_64BIT.
- Use a single revb.2h instruction for bswapsi2 (x) r>> 16, and a single
revb.2w instruction for bswapdi2 (x) r>> 32.
Unfortunately I cannot figure out a way to make the compiler generate
revb.4h or revh.{2w,d} instructions.

In r15-1207 I was too stupid to realize we just need to relax
ins_zero_bitmask_operand to allow using bstrins for aligning, instead of
adding a new split. And, "> 12" in ins_zero_bitmask_operand also makes
no sense: it rejects bstrins for things like "x & ~4l" with no good

if TARGET_64BIT
We already had "si3_extend" insns and we hoped the fwprop or combine
passes can use them to remove unnecessary sign extensions. But this
does not always work: for cases like x << 1 | y, the compiler
tends to do
(sign_extend:DI
(ior:SI (ashift:SI (reg:SI $r4)
(const_int 1))
(reg:SI $r5)))
instead of
(ior:DI (sign_extend:DI (ashift:SI (reg:SI $r4) (const_int 1)))
(sign_extend:DI (reg:SI $r5)))
So we cannot match the ashlsi3_extend instruction here and we get:
slli.w $r4,$r4,1
or $r4,$r5,$r4
slli.w $r4,$r4,0 # <= redundant
jr $r1
To eliminate this redundant extension we need to turn SImode shift etc.
to DImode "si3_extend" operations earlier, when we expand the SImode
operation. We are already doing this for addition, now do it for
shifts, rotates, substract, multiplication, division, and modulo as
well.
The bytepick.w definition for TARGET_64BIT needs to be adjusted so it
won't be undone by the shift expanding.
gcc/ChangeLog:
* config/loongarch/loongarch.md (optab): Add (rotatert "rotr").

Consider

a &= ~0xfff;
b &= ~0xfff;
a |= c;

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.

We were comparing a mode size with word_mode, but word_mode is an enum
value thus this does not really make any sense. (Un)luckily E_DImode
happens to be 8 so this seemed to work, but let's make it correct so it

While looking at the index I noticed that some options had
`-` in the front for the index which is wrong. And then
I noticed there was no index for `mcmodel=` for targets or had
used `-mcmodel` incorrectly.
This fixes both of those and regnerates the urls files see that
`-mcmodel=` option now has an url associated with it.

We were assuming TYPE_NO_NAMED_ARGS_STDARG_P don't have any named
arguments and there is nothing to advance, but that is not the case
for (...) functions returning by hidden reference which have one such
artificial argument. This is causing gcc.dg/c23-stdarg-6.c and
gcc.dg/c23-stdarg-8.c to fail.
Fix the issue by checking if arg.type is NULL, as r14-9503 explains.

The behavior of non-zero unused bits in xvpermi.q instruction's
third operand is undefined on LoongArch, according to our
discussion (https://github.com/llvm/llvm-project/pull/83540),
we think that keeping original insn operand as unmodified
state is better solution.

If this insn is really used, we'll have something like
slti $r4,$r0,$r5
in the code. The assembler will reject it because slti wants 2
register operands and 1 immediate operand. But we've not got any bug
report for this, indicating this define_insn is unused at all.
Note that do_store_flag (in expr.cc) is already converting x >= 1 to
x > 0 unconditionally, so this define_insn is indeed unused and we can
just remove it.

allow the IE to LE linker relaxation
In Binutils we need to make IE to LE relaxation only allowed when there
is an R_LARCH_RELAX after R_LARCH_TLE_IE_PC_{HI20,LO12} so an invalid
"partial" relaxation won't happen with the extreme code model. So if we
are emitting %ie_pc_{hi20,lo12} in a non-extreme code model, emit an
R_LARCH_RELAX to allow the relaxation. The IE to LE relaxation does not
require the pcalau12i and the ld instruction to be adjacent, so we don't
need to limit ourselves to use the macro.
For the distro maintainers backporting changes: this change depends on
r14-8721, without r14-8721 R_LARCH_RELAX can be emitted mistakenly in
the extreme code model.

* config/loongarch/loongarch.cc (loongarch_print_operand_reloc):
Support 'Q' for R_LARCH_RELAX for TLS IE.
(loongarch_output_move): Use 'Q' to print R_LARCH_RELAX for TLS
IE.

atomic_compare_and_swapsi.
If the hardware does not support LAMCAS, atomic_compare_and_swapsi needs to be
implemented through "ll.w+sc.w". In the implementation of the instruction sequence,
it is necessary to determine whether the two registers are equal.
Since LoongArch's comparison instructions do not distinguish between 32-bit
and 64-bit, the two operand registers that need to be compared are symbolically
extended, and one of the operand registers is obtained from memory through the
"ll.w" instruction, which can ensure that the symbolic expansion is carried out.
However, the value of the other operand register is not guaranteed to be the
value of the sign extension.
gcc/ChangeLog:
* config/loongarch/sync.md (atomic_cas_value_strong<mode>):
In loongarch64, a sign extension operation is added when
operands[2] is a register operand and the mode is SImode.

The specification of crc/crcc instructions is clear that the output is
sign-extended to GRLEN. Add a define_insn to tell the compiler this
fact and allow it to remove the unneeded sign extension on crc/crcc

this should produce a significant performance gain.
