This patch expresses the intrinsics for the SRA and RSRA instructions with
standard RTL codes rather than relying on UNSPECs.
These instructions perform a vector shift right plus accumulate with an
optional rounding constant addition for the RSRA variant.
There are a number of interesting points:
* The scalar-in-SIMD-registers variant for DImode SRA e.g. ssra d0, d1, #N
is left using the UNSPECs. Expressing it as a DImode plus+shift led to all
kinds of trouble as it started matching the existing define_insns for
"add x0, x0, asr #N" instructions and adding the SRA form as an extra
alternative required a significant amount of deduplication of iterators and
things still didn't work out well. I decided not to tackle that case in
this patch. It can be attempted later.
* For the RSRA variants that add a rounding constant (1 << (shift-1)) the
addition is notionally performed in a wider mode than the input types so that
overflow is handled properly. In RTL this can be represented with an appropriate
extend operation followed by a truncate back to the original modes.
However for 128-bit input modes such as V4SI we don't have appropriate modes
defined for this widening i.e. we'd need a V4DI mode to represent the
intermediate widened result. This patch defines such modes for
V16HI,V8SI,V4DI,V2TI. These will come handy in the future too as we have
more Advanced SIMD instruction that have similar intermediate widening
semantics.
* The above new modes led to a problem with stor-layout.cc. The new modes only
exist for the sake of the RTL optimisers understanding the semantics of the
instruction but are not indended to be moved to and from register or memory,
assigned to types, used as TYPE_MODE or participate in auto-vectorisation.
This is expressed in aarch64 by aarch64_classify_vector_mode returning zero
for these new modes. However, the code in stor-layout.cc:<mode_for_vector>
explicitly doesn't check this when picking a TYPE_MODE due to modes being made
potentially available later through target switching (PR38240).
This led to these modes being picked as TYPE_MODE for declarations such as:
typedef int16_t vnx8hi __attribute__((vector_size (32))) when 256-bit
fixed-length SVE modes are available and vector_type_mode later struggling
to rectify this.
This issue is addressed with the new target hook
TARGET_VECTOR_MODE_SUPPORTED_ANY_TARGET_P that is intended to check if a
vector mode can be used in any legal target attribute configuration of the
port, as opposed to the existing TARGET_VECTOR_MODE_SUPPORTED_P that checks
only the initial target configuration. This allows a simple adjustment in
stor-layout.cc that still disqualifies these limited modes early on while
allowing consideration of modes that can be turned on in the future with
target attributes.
Bootstrapped and tested on aarch64-none-linux-gnu.

As has been discussed before, the following patch adds target hook
for math library function maximum errors measured in ulps.
The default is to return ~0U which is a magic maximum value which means
nothing is known about precision of the match function.
The first argument is unsigned int because enum combined_fn isn't available
everywhere where target hooks are included but is expected to be given
the enum combined_fn value, although it should be used solely to find out
which kind of match function (say sin vs. cos vs. sqrt vs. exp10) rather
than its variant (f suffix, no suffix, l suffix, f128 suffix, ...), for
which there is the machine_mode argument.
The last argument is a bool, if it is false, the function should return
maximum known error in ulps for a given function (taking -frounding-math
into account if enabled), with 0.5ulps being represented as 0.
If it is true, it is about whether the function can return values outside of
an intrinsic finite range for the function and by how many ulps.
E.g. sin/cos should return result in [-1.,1], if the function is expected
to never return values outside of that finite interval, the hook should
return 0. Similarly for sqrt such range is [-0.,+Inf].
The patch implements it for glibc only so far, I hope other maintainers
can submit details for Solaris, musl, perhaps BSDs, etc.
For glibc I've gathered data from:
1) https://www.gnu.org/software/libc/manual/html_node/Errors-in-Math-Functions.html
as latest published glibc data
2) https://www.gnu.org/software/libc/manual/2.22/html_node/Errors-in-Math-Functions.html
as a few years old glibc data
3) using attached libc-ulps.sh script from glibc git
4) using attached ulp-tester.c (how to invoke in file comment; tested
both x86_64, ppc64, ppc64le 50M pseudo-random values in all 4 rounding
modes, plus on x86_64 float/double sin/cos using libmvec - see
attached libmvec-wrapper.c as well)
5) using attached boundary-tester.c to test for whether sin/cos/sqrt return
values outside of the intrinsic ranges for those functions (again,
tested on x86_64, ppc64, ppc64le plus on x86_64 using libmvec as well;
libmvec with non-default rounding modes is pretty much random number
generator it seems)
The data is added to various hooks, the generic and generic glibc versions
being in targhooks.c so that the various targets can easily override it.
The intent is that the generic glibc version handles most of the stuff
and specific target arch overrides handle the outliers or special cases.
The patch has special case for x86_64 when __FAST_MATH__ is defined (as
one can use in that case either libm or libmvec and we don't know which
one will be used; so it uses maximum of what libm provides and libmvec),
rs6000 (had to add one because cosf has 3ulps on ppc* rather than 1-2ulps
on most other targets; MODE_COMPOSITE_P could be in theory handled in the
generic code too, but as we have rs6000-linux specific function, it can be
done just there), arc-linux (because DFmode sin has 7ulps there compared to
1ulps on other targets, both in default rounding mode and in others) and
or1k-linux (while DFmode sin has 1ulps there for default rounding mode,
for other rounding modes it has up to 7ulps).
Now, for -frounding-math I'm trying to add a few ulps more because I expect
it to be much less tested, except that for boundary_p I try to use
the numbers I got from the 5) tester.

The following testcase is miscompiled on aarch64-linux in the regname pass,
because while the function takes arguments in the p0 register,
FUNCTION_ARG_REGNO_P doesn't reflect that, so DF doesn't know the register is
used in register passing. It sees 2 chains with p1 register and wants to
replace the second one and as DF doesn't know p0 is live at the start of the
function, it will happily use p0 register even when it is used in subsequent
instructions.
The following patch fixes that. FUNCTION_ARG_REGNO_P returns non-zero
for p0-p3 (unconditionally, seems for the floating/vector registers it
doesn't conditionalize them on TARGET_FLOAT either, but if you want,
I can conditionalize p0-p3 on TARGET_SVE), similarly
targetm.calls.function_value_regno_p returns true for p0-p3 registers
if TARGET_SVE (again for consistency, that function conditionalizes
the float/vector on TARGET_FLOAT).
Now, that change broke bootstrap in libobjc and some
__builtin_apply_args/__builtin_apply/__builtin_return tests. The
aarch64_get_reg_raw_mode hook already documents that SVE scalable arg/return
passing is fundamentally incompatible with those builtins, but unlike
the floating/vector regs where it forces a fixed vector mode, I think
there is no fixed mode which could be used for p0-p3. So, I have tweaked
the generic code so that it uses VOIDmode return from that hook to signal
that a register shouldn't be touched by
__builtin_apply_args/__builtin_apply/__builtin_return
despite being mentioned in FUNCTION_ARG_REGNO_P or
targetm.calls.function_value_regno_p.

This now implements a hook
preferred_div_as_shifts_over_mult that indicates whether a target prefers that
the vectorizer decomposes division as shifts rather than multiplication when
possible.
In order to be able to use this we need to check whether the current precision
has enough bits to do the operation without any of the additions overflowing.
We use range information to determine this and only do the operation if we're
sure am overflow won't occur. This now uses ranger to do this range check.
This seems to work better than vect_get_range_info which uses range_query, but I
have not switched the interface of vect_get_range_info over in this PR fix.
As Andy said before initializing a ranger instance is cheap but not free, and if
the intention is to call it often during a pass it should be instantiated at
pass startup and passed along to the places that need it. This is a big
refactoring and doesn't seem right to do in this PR. But we should in GCC 14.
Currently we only instantiate it after a long series of much cheaper checks.

ia32 with -mno-sse2 [PR108883]
_Float16 and decltype(0.0bf16) types are on x86 supported only with
-msse2. On x86_64 that is the default, but on ia32 it is not.
We should still emit fundamental type tinfo for those types in
libsupc++.a/libstdc++.*, regardless of whether libsupc++/libstdc++
is compiled with -msse2 or not, as user programs can be compiled
with different ISA flags from libsupc++/libstdc++ and if they
are compiled with -msse2 and use std::float16_t or std::bfloat16_t
and need RTTI for it, it should work out of the box. Furthermore,
libstdc++ ABI on ia32 shouldn't depend on whether the library
is compiled with -mno-sse or -msse2.
Unfortunately, just hacking up libsupc++ Makefile/configure so that
a single source is compiled with -msse2 isn't appropriate, because
that TU emits also code and the code should be able to run on CPUs
which libstdc++ supports. We could add [[gnu::attribute ("no-sse2")]]
there perhaps conditionally, but it all gets quite ugly.
The following patch instead adds a target hook which allows the backend
to temporarily tweak registered types such that emit_support_tinfos
emits whatever is needed.
Additionally, it makes emit_support_tinfos_1 call emit_tinfo_decl
immediately, so that temporarily created dummy types for emit_support_tinfo
purposes only can be nullified again afterwards. And removes the
previous fallback_* types used for dfloat*_type_node tinfos even when
decimal types aren't supported.

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:

In plenty of image and video processing code it's common to modify pixel values
by a widening operation and then scale them back into range by dividing by 255.
e.g.:
x = y / (2 ^ (bitsize (y)/2)-1
This patch adds a new target hook can_special_div_by_const, similar to
can_vec_perm which can be called to check if a target will handle a particular
division in a special way in the back-end.
The vectorizer will then vectorize the division using the standard tree code
and at expansion time the hook is called again to generate the code for the
division.
Alot of the changes in the patch are to pass down the tree operands in all paths
that can lead to the divmod expansion so that the target hook always has the
type of the expression you're expanding since the types can change the
expansion.

C2x allows function prototypes to be given as (...), a prototype
meaning a variable-argument function with no named arguments. To
allow such functions to access their arguments, requirements for
va_start calls are relaxed so it ignores all but its first argument
(i.e. subsequent arguments, if any, can be arbitrary pp-token
sequences).
Implement this feature accordingly. The va_start relaxation in
<stdarg.h> is itself easy: __builtin_va_start already supports a
second argument of 0 instead of a parameter name, and calls get
converted internally to the form using 0 for that argument, so
<stdarg.h> just needs changing to use a variadic macro that passes 0
as the second argument of __builtin_va_start. (This is done only in
C2x mode, on the expectation that users of older standard would expect
unsupported uses of va_start to be diagnosed.)
For the (...) functions, it's necessary to distinguish these from
unprototyped functions, whereas previously C++ (...) functions and
unprototyped functions both used NULL TYPE_ARG_TYPES. A flag is added
to tree_type_common to mark the (...) functions; as discussed on gcc@,
doing things this way is likely to be safer for unchanged code in GCC
than adding a different form of representation in TYPE_ARG_TYPES, or
adding a flag that instead signals that the function is unprototyped.
There was previously an option
-fallow-parameterless-variadic-functions to enable support for (...)
prototypes. The support was incomplete - it treated the functions as
unprototyped, and only parsed some declarations, not e.g.
"int g (int (...));". This option is changed into a no-op ignored
option; (...) is always accepted syntactically, with a pedwarn_c11
call to given required diagnostics when appropriate. The peculiarity
of a parameter list with __attribute__ followed by '...' being
accepted with that option is removed.
Interfaces in tree.cc that create function types are adjusted to set
this flag as appropriate. It is of course possible that some existing
users of the functions to create variable-argument functions actually
wanted unprototyped functions in the no-named-argument case, rather
than functions with a (...) prototype; some such cases in c-common.cc
(for built-in functions and implicit function declarations) turn out
to need updating for that reason.
I didn't do anything to change how the C++ front end creates (...)
function types. It's very likely there are unchanged places in the
compiler that in fact turn out to need changes to work properly with
(...) function prototypes.
Target setup_incoming_varargs hooks, where they used the information
passed about the last named argument, needed updating to avoid using
that information in the (...) case. Note that apart from the x86
changes, I haven't done any testing of those target changes beyond
building cc1 to check for syntax errors. It's possible further
target-specific fixes will be needed; target maintainers should watch
out for failures of c2x-stdarg-4.c or c2x-stdarg-split-1a.c, the
execution tests, which would indicate that this feature is not working
correctly. Those tests also verify the case where there are named
arguments but the last named argument has a declaration that results
in undefined behavior in previous C standard versions, such as a type
changed by the default argument promotions.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

This change introduces a target overridable macro to replace
the hardcoded value used to initialize dwarf_version from common.opt.
The main advantage compared to special code in a target
override_options hook is that redefinitions by target config files
are visible by both the compiler proper and by the driver, which
might refer to dwarf_version in ASM_DEBUG_SPECs and friends.
This is useful at least on VxWorks, where we usually need to
default to dwarf 4 or even 2 to accommodate non-gdb debuggers
provided by the environment, including for assembly sources
used in libgcc for some ports (witnessed with lse.S on aarch64).

The mingw32 port is the only port to have TARGET_OVERRIDES_FORMAT_ATTRIBUTES
defined. When this macro is defined, it will never evaluate to NULL and produce
a warning: "error: the address of 'mingw_format_attribute_overrides' will never
be NULL [-Werror=address]"
Also, when TARGET_OVERRIDES_FORMAT_ATTRIBUTES is defined,
TARGET_OVERRIDES_FORMAT_ATTRIBUTES_COUNT must be defined as well. Add that
requirement to the docs.

Create a new hook to let target could override the multi-lib result,
the motivation is RISC-V might have very complicated multi-lib re-use
rule*, which is hard to maintain and use current multi-lib scripts,
we even hit the "argument list too long" error when we tried to add more
multi-lib reuse rule.
So I think it would be great to have a target specific way to determine
the multi-lib re-use rule, then we could write those rule in C, instead
of expand every possible case in MULTILIB_REUSE.
* Here is an example for RISC-V multi-lib rules:

The vecsize_int/vecsize_float has an assumption that all arguments will use
the same bitsize, and vary the number of lanes according to the element size,
but this is inappropriate on targets where the number of lanes is fixed and
the bitsize varies (i.e. amdgcn).
With this change the vecsize can be left zero and the vectorization factor will
be the same for all types.

The rationale of the patch is to support vec_perm_expr of the form:
lhs = vec_perm_expr<rhs, mask>
where lhs and rhs are vector types with different lengths but have
same element type. For example, lhs is SVE vector and rhs
is corresponding AdvSIMD vector.
It would also allow to express extract even/odd and interleave operations
with a VEC_PERM_EXPR. The interleave currently has the issue that we have
to artificially widen the inputs with "dont-care" elements.

We should make sure that the hard register set that is actually cleared by
the target hook zero_call_used_regs should be a subset of all call used
registers.
At the same time, update documentation for the target hook
TARGET_ZERO_CALL_USED_REGS.
This new assertion identified a bug in the i386 implemenation, which
incorrectly set the zeroed_hardregs for stack registers. Fixed this bug
in i386 implementation.

Shadow Call Stack can be used to protect the return address of a
function at runtime, and clang already supports this feature[1].
To enable SCS in user mode, in addition to compiler, other support
is also required (as discussed in [2]). This patch only adds basic
support for SCS from the compiler side, and provides convenience
for users to enable SCS.
For linux kernel, only the support of the compiler is required.

Power ISA 2.07 (Power8) introduces transactional memory
feature but ISA3.1 (Power10) removes it. It exposes one
troublesome issue as PR102059 shows. Users define some
function with target pragma cpu=power10 then it calls one
function with attribute always_inline which inherits
command line option -mcpu=power8 which enables HTM
implicitly. The current isa_flags check doesn't allow this
inlining due to "target specific option mismatch" and error
mesasge is emitted.
Normally, the callee function isn't intended to exploit HTM
feature, but the default flag setting make it look it has.
As Richi raised in the PR, we have fp_expressions flag in
function summary, and allow us to check the function
actually contains any floating point expressions to avoid
overkill. So this patch follows the similar idea but is
more target specific, for this rs6000 port specific
requirement on HTM feature check, we would like to check
rs6000 specific HTM built-in functions and inline assembly,
it allows targets to do their own customized checks and
updates.
It introduces two target hooks need_ipa_fn_target_info and
update_ipa_fn_target_info. The former allows target to do
some previous check and decides to collect target specific
information for this function or not. For some special
case, it can predict the analysis result and set it early
without any scannings. The latter allows the
analyze_function_body to pass gimple stmts down just like
fp_expressions handlings, target can do its own tricks.
I put them together as one hook initially with one boolean
to indicate whether it's initial time, but the code looks a
bit ugly, to separate them seems to have better readability.

1. On some targets, like PowerPC, reference to ifunc function resolver
must be non-local so that compiler will properly emit PLT call. Add
TARGET_IFUNC_REF_LOCAL_OK to allow binding indirect function resolver
locally for targets which don't require special PLT call sequence.
2. Add ix86_call_use_plt_p to call local ifunc function resolvers via
PLT.

For at least one target (Darwin) the platform convention is to
register static destructors (i.e. __attribute__((destructor)))
with __cxa_atexit rather than placing them into a list that is
run by some other mechanism.
This patch provides a target hook that allows a target to opt
into this and handling for the process in ipa_cdtor_merge ().
When the mode is enabled (dtors_from_cxa_atexit is set) we:
* Generate new CTORs to register static destructors with
__cxa_atexit and add them to the existing list of CTORs;
we then process the revised CTORs list.
* We sort the DTORs into priority and then TU order, this
means that they are registered in that order with
__cxa_atexit () and therefore will be run in the reverse
order.
* Likewise, CTORs are sorted into priority and then TU order,
which means that they will run in that order.
This matches the behavior of using init/fini (or
mod_init_func/mod_term_func) sections.
This also fixes a bug where Fortran needs a DTOR to be run to
close IO.

The current vector cost interface has a quite a bit of redundancy
built in. Each target that defines its own hooks has to replicate
the basic unsigned[3] management. Currently each target also
duplicates the cost adjustment for inner loops.
This patch instead defines a vector_costs class for holding
the scalar or vector cost and allows targets to subclass it.
There is then only one costing hook: to create a new costs
structure of the appropriate type. Everything else can be
virtual functions, with common concepts implemented in the
base class rather than in each target's derivation.
This might seem like excess C++-ification, but it shaves
~100 LOC. I've also got some follow-on changes that become
significantly easier with this patch. Maybe it could help
with things like weighting blocks based on frequency too.
This will clash with Andre's unrolling patches. His patches
have priority so this patch should queue behind them.
The x86 and rs6000 parts fully convert to a self-contained class.
The equivalent aarch64 changes are more complex, so this patch
just does the bare minimum. A later patch will rework the
aarch64 bits.

This patch implements an algorithm to lay out local data-share (LDS)
space. It currently works for AMD GCN. At the moment, LDS is used for
three things:
1. Gang-private variables
2. Reduction temporaries (accumulators)
3. Broadcasting for worker partitioning
After the patch is applied, (2) and (3) are placed at preallocated
locations in LDS, and (1) continues to be handled by the backend (as it
is at present prior to this patch being applied). LDS now looks like this:
+--------------+ (gang-private size + 1024, = 1536)
| free space |
| ... |
| - - - - - - -|
| worker bcast |
+--------------+
| reductions |
+--------------+ <<< -mgang-private-size=<number> (def. 512)
| gang-private |
| vars |
+--------------+ (32)
| low LDS vars |
+--------------+ LDS base
So, gang-private space is fixed at a constant amount at compile time
(which can be increased with a command-line switch if necessary
for some given code). The layout algorithm takes out a slice of the
remainder of usable space for reduction vars, and uses the rest for
worker partitioning.
The partitioning algorithm works as follows.
1. An "adjacency" set is built up for each basic block that might
do a broadcast. This is calculated by starting at each such block,
and doing a recursive DFS walk over successors to find the next
block (or blocks) that *also* does a broadcast
(dfs_broadcast_reachable_1).
2. The adjacency set is inverted to get adjacent predecessor blocks also.
3. Blocks that will perform a broadcast are sorted by size of that
broadcast: the biggest blocks are handled first.
4. A splay tree structure is used to calculate the spans of LDS memory
that are already allocated by the blocks adjacent to this one
(merge_ranges{,_1}.
5. The current block's broadcast space is allocated from the first free
span not allocated in the splay tree structure calculated above
(first_fit_range). This seems to work quite nicely and efficiently
with the splay tree structure.
6. Continue with the next-biggest broadcast block until we're done.
In this way, "adjacent" broadcasts will not use the same piece of
LDS memory.
PR96334 "openacc: Unshare reduction temporaries for GCN" got merged in:
The GCN backend uses tree nodes like MEM((__lds TYPE *) <constant>)
for reduction temporaries. Unlike e.g. var decls and SSA names, these
nodes cannot be shared during gimplification, but are so in some
circumstances. This is detected when appropriate --enable-checking
options are used. This patch unshares such nodes when they are reused
more than once.

If -fprofile-update=atomic is used, then the target must provide atomic
operations for the counters of the type returned by get_gcov_type().
This is a 64-bit type for targets which have a 64-bit long long type.
On 32-bit targets this could be an issue since they may not provide
64-bit atomic operations. Allow targets to override the default type
size with the new TARGET_GCOV_TYPE_SIZE target hook.
If a 32-bit gcov type size is used, then there is currently a warning in
libgcov-driver.c in a dead code block due to
sizeof (counter) == sizeof (gcov_unsigned_t):

This patch implements worker-partitioning support in the middle end,
by rewriting gimple. The OpenACC execution model requires that code
can run in either "worker single" mode where only a single worker per
gang is active, or "worker partitioned" mode, where multiple workers
per gang are active. This means we need to do something equivalent
to spawning additional workers when transitioning from worker-single
to worker-partitioned mode. However, GPUs typically fix the number of
threads of invoked kernels at launch time, so we need to do something
with the "extra" threads when they are not wanted.
The scheme used is to conditionalise each basic block that executes
in "worker single" mode for worker 0 only. Conditional branches
are handled specially so "idle" (non-0) workers follow along with
worker 0. On transitioning to "worker partitioned" mode, any variables
modified by worker 0 are propagated to the other workers via GPU shared
memory. Special care is taken for routine calls, writes through pointers,
and so forth, as follows:
- There are two types of function calls to consider in worker-single
mode: "normal" calls to maths library routines, etc. are called from
worker 0 only. OpenACC routines may contain worker-partitioned loops
themselves, so are called from all workers, including "idle" ones.
- SSA names set in worker-single mode, but used in worker-partitioned
mode, are copied to shared memory in worker 0. Other workers retrieve
the value from the appropriate shared-memory location after a barrier,
and new phi nodes are introduced at the convergence point to resolve
the worker 0/other worker copies of the value.
- Local scalar variables (on the stack) also need special handling. We
broadcast any variables that are written in the current worker-single
block, and that are read in any worker-partitioned block. (This is
believed to be safe, and is flow-insensitive to ease analysis.)
- Local aggregates (arrays and composites) on the stack are *not*
broadcast. Instead we force gimple stmts modifying elements/fields of
local aggregates into fully-partitioned mode. The RHS of the
assignment is a scalar, and is thus subject to broadcasting as above.
- Writes through pointers may affect any local variable that has
its address taken. We use points-to analysis to determine the set
of potentially-affected variables for a given pointer indirection.
We broadcast any such variable which is used in worker-partitioned
mode, on a per-block basis for any block containing a write through
a pointer.

Currently, doloop.xx variable is using the type as niter which may be
shorter than word size. For some targets, it would be better to use
word size type. For example, on 64bit system, to access 32bit value,
subreg maybe used. Then using 64bit type maybe better for niter if
it can be present in both 32bit and 64bit.
This patch add target hook to query preferred mode for doloop IV,
and update mode accordingly.

CTF/BTF debug formats can be safely enabled for all ELF-based targets by
default in GCC.
CTF/BTF debug formats now adopt a similar approach as taken for DWARF debug
format via the DWARF2_DEBUGGING_INFO.
- By default, CTF/BTF formats can be enabled for all ELF-based targets.
- By default, CTF/BTF formats can be disabled for all non ELF-based targets.
- If the user passed a -gctf but CTF is not enabled for the target, GCC
issues an error to the user (as is done currently with other debug formats) -
"target system does not support the 'ctf' debug format". Analogous behavior
for -gbtf command line option.
A previous commit disabled the CTF and BTF testcases on the AIX platform. This
is not necessary now that CTF and BTF debug formats are disabled by default on
all non-ELF targets. GCC emits an error message when -gctf/-gbtf is used on
such platforms and these tests will be skipped.

1. Replace PUSH_ARGS with a target calls hook, TARGET_PUSH_ARGUMENT, which
takes an integer argument. When it returns true, push instructions will
be used to pass outgoing arguments. If the argument is nonzero, it is
the number of bytes to push and indicates the PUSH instruction usage is
optional so that the backend can decide if PUSH instructions should be
generated. Otherwise, the argument is zero.
2. Implement x86 target hook which returns false when the number of bytes
to push is no less than 16 (8 for 32-bit targets) if vector load and store
can be used.
3. Remove target PUSH_ARGS definitions which return 0 as it is the same
as the default.
4. Define TARGET_PUSH_ARGUMENT of cr16 and m32c to always return true.
