Refactor the loops to all use the same form, and to not need explicit
'break' or 'continue' jumps. This also avoids a -Wunused-variable
warning with -Wsystem-headers.
Also fix a bug for absolute timeouts specified with a time that isn't
implicitly convertible to __clock_t::time_point, e.g. one with a higher
resolution such as picoseconds. Use chrono::ceil to round up to the next
time point representable by the clock.

The transparent call insns like "*parityhi2.libgcc" output a single
[R]CALL instruction that can be skipped by the skip instructions.
Such insns have attribute "type" of "xcall" and can therefore
be easily recognized. Same applies when "adjust_len" is "call".

* config/avr/avr.cc (avr_2word_insn_p): Return true for
transparent calls: When insn attribute "type" is "xcall"

While working on a different patch, I noticed the heuristics were not
doing the right thing if there was statements before the NOP/PREDICTs.
(LABELS don't have other statements before them).
This fixes that oversight which was added in r15-3334-gceda727dafba6e.
Bootstrapped and tested on x86_64-linux-gnu.
gcc/ChangeLog:
* tree-ssa-phiopt.cc (factor_out_conditional_operation): Instead
of just ignorning a NOP/PREDICT, skip over them before checking

There are many places where asm output functions have to look at

PR116696 expressed surprise that explicit 'constexpr' was needed on one
function; this was because the function isn't 'inline', and
-fimplicit-constexpr doesn't try to promote non-inline functions. Let's be
more helpful in that situation, and also help trace through functions that
were promoted.

Jonathan reported on IRC that certain unnamed proprietary static analyzer
is unhappy about the new finish_embed function and it is actually right.
On a testcase like:
#embed __FILE__ limit (0) if_empty (0)
params->if_empty.count is 1, limit is 0, so count is 0 (we need just
a single token and one fits into pfile->directive_result). Because
count is 0, we don't allocate toks, so it stays NULL, and then in
1301 if (prefix->count)
1302 {
1303 *tok = *prefix->base_run.base;
1304 tok = toks;
1305 tokenrun *cur_run = &prefix->base_run;
1306 while (cur_run)
1307 {
1308 size_t cnt = (cur_run->next ? cur_run->limit
1309 : prefix->cur_token) - cur_run->base;
1310 cpp_token *t = cur_run->base;
1311 if (cur_run == &prefix->base_run)
1312 {
1313 t++;
1314 cnt--;
1315 }
1316 memcpy (tok, t, cnt * sizeof (cpp_token));
1317 tok += cnt;
1318 cur_run = cur_run->next;
1319 }
1320 }
the *tok = *prefix->base_run.base; assignment will copy the only
token. cur_run is still non-NULL, cnt will be initially 1 and
then decremented to 0, but we invoke UB because we do
memcpy (NULL, cur_run->base + 1, 0 * sizeof (cpp_token));
and then the loop stops because cur_run->next must be NULL.
As we don't really copy anything, toks can be anything non-NULL,
so the following patch fixes that by initializing toks also to
&pfile->directive_result (just something known to be non-NULL).
This should be harmless even for the
#embed __FILE__ limit (1)
case (no non-empty prefix/suffix) where toks isn't allocated
either, but in that case prefix->count will be 0 and in the
1321 for (size_t i = 0; i < limit; ++i)
1322 {
1323 tok->src_loc = params->loc;
1324 tok->type = CPP_NUMBER;
1325 tok->flags = NO_EXPAND;
1326 if (i == 0)
1327 tok->flags |= PREV_WHITE;
1328 tok->val.str.text = s;
1329 tok->val.str.len = sprintf ((char *) s, "%d", buffer[i]);
1330 s += tok->val.str.len + 1;
1331 if (tok == &pfile->directive_result)
1332 tok = toks;
1333 else
1334 tok++;
1335 if (i < limit - 1)
1336 {
1337 tok->src_loc = params->loc;
1338 tok->type = CPP_COMMA;
1339 tok->flags = NO_EXPAND;
1340 tok++;
1341 }
1342 }
loop limit will be 1, so tok is initially &pfile->directive_result,
that is stilled in, then tok = toks; (previously setting tok to NULL,
now to &pfile->directive_result again) and because 0 < 1 - 1 is
false, nothing further will happen and the loop will finish (and as
params->suffix.count will be 0, nothing further will use tok).
2024-09-13 Jakub Jelinek <jakub@redhat.com>
* files.cc (finish_embed): Initialize toks to tok rather
than NULL.

Currently subregs originating from *tf_to_fprx2_0 and *tf_to_fprx2_1
survive register allocation. This in turn leads to wrong register
renaming. Keeping the current approach would mean we need two insns for
*tf_to_fprx2_0 and *tf_to_fprx2_1, respectively. Something along the
lines
(define_insn "*tf_to_fprx2_0"
[(set (subreg:DF (match_operand:FPRX2 0 "nonimmediate_operand" "=f") 0)
(unspec:DF [(match_operand:TF 1 "general_operand" "v")]
UNSPEC_TF_TO_FPRX2_0))]
"TARGET_VXE"
"#")
(define_insn "*tf_to_fprx2_0"
[(set (match_operand:DF 0 "nonimmediate_operand" "=f")
(unspec:DF [(match_operand:TF 1 "general_operand" "v")]
UNSPEC_TF_TO_FPRX2_0))]
"TARGET_VXE"
"vpdi\t%v0,%v1,%v0,1
[(set_attr "op_type" "VRR")])
and similar for *tf_to_fprx2_1. Note, pre register allocation operand 0
has mode FPRX2 and afterwards DF once subregs have been eliminated.
Since we always copy a whole vector register into a floating-point
register pair, another way to fix this is to merge *tf_to_fprx2_0 and
*tf_to_fprx2_1 into a single insn which means we don't have to use
subregs at all. The downside of this is that the assembler template
contains two instructions, now. The upside is that we don't have to
come up with some artificial insn before RA which might be more
readable/maintainable. That is implemented by this patch.
In commit r11-4872-ge627cda5686592, the output operand specifier %V was
introduced which is used in tf_to_fprx2 only, now. Instead of coming up
with its counterpart %F for floating-point registers, which would also
only be used in tf_to_fprx2, I print the operands directly. This
renders %V unused which is why it is removed by this patch.

This commit ports the fixes already applied by r13-6372-g822a11a1e642e0
to the range-based versions of copy/move algorithms.
When doing so, a further bug (PR116471) was discovered in the
implementation of the range-based algorithms: although the algorithms
are already constrained by the indirectly_copyable/movable concepts,
there was a failing static_assert in the memmove path.
This static_assert checked that iterator's value type was assignable by
using the is_copy_assignable (move) type traits. However, this is a
problem, because the traits are too strict when checking for constness;
a type like
struct S { S& operator=(S &) = default; };
is trivially copyable (and thus could benefit of the memmove path),
but it does not satisfy is_copy_assignable because the operator takes
by non-const reference.
Now, the reason for the check to be there is because a type with
a deleted assignment operator like
struct E { E& operator=(const E&) = delete; };
is still trivially copyable, but not assignable. We don't want
algorithms like std::ranges::copy to compile because they end up
selecting the memmove path, "ignoring" the fact that E isn't even
copy assignable.
But the static_assert isn't needed here any longer: as noted before,
the ranges algorithms already have the appropriate constraints; and
even if they didn't, there's now a non-discarded codepath to deal with
ranges of length 1 where there is an explicit assignment operation.
Therefore, this commit removes it. (In fact, r13-6372-g822a11a1e642e0
removed the same static_assert from the non-ranges algorithms.)

16-bit comparisons like R25:24 == -1 are currently performed like
cpi R24, -1
cpc R25, R24
Similar is possible for wider modes. ADIW can be used like SBIW when
the compare code is EQ or NE because such comparisons are just about
(propagating) the Z flag. The patch adds helper functions like avr_byte()
that may be useful in other functions than avr_out_compare().
Use new convenient helper functions that may be useful in
other output functions, too.
For example, with the patch
R24:SI == -1 (unused after)
adiw r26,1
sbci r25,hi8(-1)
sbci r24,lo8(-1)
R18:SI == -1
cpi r18,-1
cpc r19,r18
cpc r20,r18
cpc r21,r18
Without the patch, we had:
R24:SI == -1 (unused after)
cpi r24,-1
sbci r25,-1
sbci r26,-1
sbci r27,-1
R18:SI == -1
cpi r18,-1

Several C++ tests fail with --disable-hosted-libstdcxx, whether
because stdc++exp gets linked in despite not being built, because
standard headers are included but that are unavailable in this mode,
or because headers are (mistakenly?) expected to introduce
declarations such as for abort, malloc, etc, but in this mode they
don't.
This patch introduces an effective target for GCC test, equivalent to
one that's available in the libstdc++-v3 testsuite, and arranges for
all such tests to be skipped when libstdc++-v3 is not hosted.

A single static assert is a much simpler way to implement the
compile-time preconditions on std::launder than an overload set of
deleted functions and function templates. The only difficulty is that
<new> doesn't include <type_traits> so we can't use std::is_function and
std::is_void for the checks. That can be worked around though, by using
the __is_same and __is_function built-ins. If the __is_function built-in
isn't supported then the __builtin_launder built-in will give an error
anyway, since the commit preceding this one.
We can also remove the redundant __cplusplus >= 201703L check around the
definitions of std::launder and the interference constants, which are
already guarded by the appropriate feature test macros.

The standard says that std::launder is ill-formed for function pointers
and cv void pointers, so there's no reason for __builtin_launder to
accept them. This change allows implementations of std::launder to defer
to the built-in for error checking, although libstdc++ will continue to
diagnose it directly for more user-friendly diagnostics.

r8-7538 for PR84968 made strip_typedefs_expr diagnose STATEMENT_LIST
so that we reject statement-expressions in noexcept-specifiers to
match our behavior in template arguments (which the parser diagnoses
directly).
Later r11-7452 made decltype(auto) deduction canonicalize the expression
(as an implementation detail) which in turn calls strip_typedefs_expr,
and so ever since we inadvertently reject decltype(auto) deduction of a
statement-expression.
This patch just removes the diagnostic in strip_typedefs_expr and instead
treats statement-expressions similar to lambda-expressions. The function
doesn't seem like the right place for such a diagnostic and so it seems
easier to just accept rather than try to reject them in a suitable place.

This patch which adds another #embed extension, gnu::base64.
As mentioned in the documentation, this extension is primarily
intended for use by the preprocessor, so that for the larger (say 32+ or
64+ bytes long embeds it doesn't have to emit tens of thousands or
millions of comma separated string literals which would be very expensive
to parse again, but can emit

with the meaning don't actually load some file, instead base64 decode
(RFC4648 with A-Za-z0-9+/ chars and = padding, no newlines in between)
the string and use that as data. This is chosen because it should be
-pedantic-errors clean, fairly cheap to decode and then in optimizing
compiler could be handled as similar binary blob to normal #embed,
while the data isn't left somewhere on the disk, so distcc/ccache etc.
can move the preprocessed source without issues.
It makes no sense to support limit and gnu::offset parameters together
with it IMHO, why would somebody waste providing full data and then
threw some away? prefix/suffix/if_empty are normally supported though,
but not intended to be used by the preprocessor.
This patch adds just the extension side, not the actual emitting of this
during -E or -E -fdirectives-only for now, that will be included in the
upcoming patch.
Compared to the earlier posted version of this extension, this patch
allows the string concatenation in the parameter argument (but still
doesn't allow escapes in the string, why would anyone use them when
only A-Za-z0-9+/= are valid). The patch also adds support for parsing
this even in -fpreprocessed compilation.

Using cpp_pedwarning (CPP_W_PEDANTIC instead of if (CPP_PEDANTIC cpp_error
lets users suppress these diagnostics with
#pragma GCC diagnostic ignored "-Wpedantic".
This patch changes all instances of the cpp_error (CPP_DL_PEDWARN to
cpp_pedwarning. In cases where the extension appears in a later C++
revision, we now condition the warning on the relevant -Wc++??-extensions
flag instead of -Wpedantic; in such cases often the if (CPP_PEDANTIC) check
is retained to preserve the default non-warning behavior.
I didn't attempt to adjust the warning flags for the C compiler, since it
seems to follow a different system than C++.
The CPP_PEDANTIC check is also kept in _cpp_lex_direct to avoid an ICE in
the self-tests from cb.diagnostics not being initialized.
While working on testcases for these changes I noticed that the c-c++-common
tests are not run with -pedantic-errors by default like the gcc.dg and
g++.dg directories are. And if I specify -pedantic-errors with dg-options,
the default -std= changes from c++?? to gnu++??, which interferes with some
other pedwarns. So two of the tests are C++-only.

This patch makes use of the new ability to unset the CPU or
architecture flags on the command line to enable several more tests on
Arm. It doesn't cover every case and it does enable some tests that
now fail for different reasons when the tests are no-longer skipped;
these were failing anyway for other testsuite configurations, so it's
still an overall improvement.
There's some restructuring required to fully implement this change: we
could previously treat Xscale as an architecture, even though the
option set -mcpu=, we now need to handle this correctly so that we
unset the architecture rather than the CPU. To do this I've added a
new table for these variants and renamed the template functions to use
'cpu' rather than 'arch'. This entailed updating the two XScale
related tests accordingly.

The compiler will warn if the architectural specification derived from
a -mcpu option is not the same as that specified by -march. This is
because it was never intended that the two should be used at the same
time: -mcpu=<name> is supposed to be shorthand for -mtune=<name>
-march=arch-of(<name>).
Unfortunately, there are times when the two options passed to the
compiler may come from distinct sources: one example is makefiles
which accumulate options; another is the testsuite itself, when some
tests require a particular architecture setting to be useful - only
running the tests when the compiler/testsuite configuration exactly
matched the requirements would make regression testing especially hard
(we have too many permutations).
So this patch allows a user to cancel any earlier setting of a
particular flag and to make the compiler behave as though it was never
passed. The intended usecase is (sources of options are shown in
parenthesis, but that's just for grouping:
(-march=armv7-a+simd) (-march=unset -mcpu=cortex-m33)
The option processing logic will now simplify this to:
-mcpu=cortex-m33
A useful corollary of this is that
-march=armv7-a -march=unset
will now cause the compiler to behave as though neither the
architecture nor the CPU was ever set and to default back to the
configure-time settings.

We crash when dependent_type_p gets a TEMPLATE_TYPE_PARM outside
a template. That happens here because in
template <template <typename T, typename T::type TT> typename X>
void func() {}
template <typename U, int I>
struct Y {};
void g() { func<Y>(); }
when performing overload resolution for func<Y>() we have to check
if U matches T and I matches TT. So we wind up in
coerce_template_template_parm/PARM_DECL. TREE_TYPE (arg) is int
so we try to substitute TT's type, which is T::type. But we have
nothing to substitute T with. And we call make_typename_type where
ctx is still T, which checks dependent_scope_p and we trip the assert.
It should work to always perform the substitution in a template context.
If the result still contains template parameters, we cannot say if they
match.

In s390_expand_insv(), if generating code for ICM et al. src is a MEM
and gen_lowpart might force src into a register such that we end up with
patterns which do not match anymore. Use adjust_address() instead in
order to preserve a MEM.
Furthermore, it is not straight forward to enforce a subreg. For
example, in case of a paradoxical subreg, gen_lowpart() may return a
register. In order to compensate this, s390_gen_lowpart_subreg() emits
a reference to a pseudo which does not coincide with its definition
which is wrong. Additionally, if dest is a paradoxical subreg, then do
not try to emit a strict_low_part since it could mean that dest was not
initialized even though this might be fixed up later by init-regs.
Splitter for insn *get_tp_64, *zero_extendhisi2_31,
*zero_extendqisi2_31, *zero_extendqihi2_31 are applied after reload.
Thus, operands[0] is a hard register and gen_lowpart (m, operands[0])
just returns the hard register for mode m which is fine to use as an
argument for strict_low_part, i.e., we do not need to enforce subregs
here since after reload subregs are supposed to be eliminated anyway.

The following patch implements the C23 N3017 "#embed - a scannable,
tooling-friendly binary resource inclusion mechanism" paper.
The implementation is intentionally dumb, in that it doesn't significantly
speed up compilation of larger initializers and doesn't make it possible
to use huge #embeds (like several gigabytes large, that is compile time
and memory still infeasible).
There are 2 reasons for this. One is that I think like it is implemented
now in the patch is how we should use it for the smaller #embed sizes,
dunno with which boundary, whether 32 bytes or 64 or something like that,
certainly handling the single byte cases which is something that can appear
anywhere in the source where constant integer literal can appear is
desirable and I think for a few bytes it isn't worth it to come up with
something smarter and users would like to e.g. see it in -E readably as
well (perhaps the slow vs. fast boundary should be determined by command
line option). And the other one is to be able to more easily find
regressions in behavior caused by the optimizations, so we have something
to get back in git to compare against.
I'm definitely willing to work on the optimizations (likely introduce a new
CPP_* token type to refer to a range of libcpp owned memory (start + size)
and similarly some tree which can do the same, and can be at any time e.g.
split into 2 subparts + say INTEGER_CST in between if needed say for
const unsigned char d[] = {
#embed "2GB.dat" prefix (0, 0, ) suffix (, [0x40000000] = 42)
}; still without having to copy around huge amounts of data; STRING_CST
owns the memory it points to and can be only 2GB in size), but would
like to do that incrementally.
And would like to first include some extensions also not included in
this patch, like gnu::offset (off) parameter to allow to skip certain
constant amount of bytes at the start of the files, plus
gnu::base64 ("base64_encoded_data") parameter to add something which can
store more efficiently large amounts of the #embed data in preprocessed
source.
I've been cross-checking all the tests also against the LLVM implementation
https://github.com/llvm/llvm-project/pull/68620
which has been for a few hours even committed to LLVM trunk but reverted
afterwards. LLVM now has the support committed and I admit I haven't
rechecked whether the behavior on the below mentioned spots have been fixed
in it already or not yet.
The patch uses --embed-dir= option that clang plans to add above and doesn't
use other variants on the search directories yet, plus there are no
default directories at least for the time being where to search for embed
files. So, #embed "..." works if it is found in the same directory (or
relative to the current file's directory) and #embed "/..." or #embed </...>
work always, but relative #embed <...> doesn't unless at least one
--embed-dir= is specified. There is no reason to differentiate between
system and non-system directories, so we don't need -isystem like
counterpart, perhaps -iquote like counterpart could be useful in the future,
dunno what else. It has --embed-directory=dir and --embed-directory dir
as aliases.
There are some differences beyond clang ICEs, so I'd like to point them out
to make sure there is agreement on the choices in the patch. They are also
mentioned in the comments of the llvm pull request.
The most important is that the GCC patch (as well as the original thephd.dev
LLVM branch on godbolt) expands #embed (or acts as if it is expanded) into
a mere sequence of numbers like 123,2,35,26 rather then what clang
effectively treats as (unsigned char)123,(unsigned char)2,(unsigned
char)35,(unsigned char)26 but only does that when using integrated
preprocessor, not when using -save-temps where it acts as GCC.
JeanHeyd as the original author agrees that is how it is currently worded in
C23.
Another difference (not tested in the testsuite, not sure how to check for
effective target /dev/urandom nor am sure it is desirable to check that
during testsuite) is how to treat character devices, named pipes etc.
(block devices are errored on). The original paper uses /dev/urandom
in various examples and seems to assume that unlike regular files the
devices aren't really cached, so
#embed </dev/urandom> limit(1) prefix(int a = ) suffix(;)
#embed </dev/urandom> limit(1) prefix(int b = ) suffix(;)
usually results in a != b. That is what the godbolt thephd.dev branch
implements too and what this patch does as well, but clang actually seems
to just go from st.st_size == 0, ergo it must be zero-sized resource and
so just copies over if_empty if present. It is really questionable
what to do about the character devices/named pipes with __has_embed, for
regular files the patch doesn't read anything from them, relies on
st.st_size + limit for whether it is empty or non-empty. But I don't know
of a way to check if read on say a character device would read anything
or not (the </dev/null> limit (1) vs. </dev/zero> limit (1) cases), and
if we read something, that would be better cached for later because
#embed later if it reads again could read no further data even when it
first read something. So, the patch currently for __has_embed just
always returns 2 on the non-regular files, like the thephd.dev
branch does as well and like the clang pull request as well.
A question is also what to do for gnu::offset on the non-regular files
even for #embed, those aren't seekable and do we want to just read and throw
away the offset bytes each time we see it used?
clang also chokes on the
#if __has_embed (__FILE__ __limit__ (1) __prefix__ () suffix (1 / 0) \
__if_empty__ ((({{[0[0{0{0(0(0)1)1}1}]]}})))) != __STDC_EMBED_FOUND__
#error "__has_embed fail"
#endif
in embed-1.c, but thephd.dev branch accepts it and I don't see why
it shouldn't, (({{[0[0{0{0(0(0)1)1}1}]]}}))) is a balanced token
sequence and the file isn't empty, so it should just be parsed and
discarded.
clang also IMHO mishandles
const unsigned char w[] = {
#embed __FILE__ prefix([0] = 42, [15] =) limit(32)
};
but again only without -save-temps, seems like it
treats it as
[0] = 42, [15] = (99,111,110,115,116,32,117,110,115,105,103,110,101,100,
32,99,104,97,114,32,119,91,93,32,61,32,123,10,35,101,109,98)
rather than
[0] = 42, [15] = 99,111,110,115,116,32,117,110,115,105,103,110,101,100,
32,99,104,97,114,32,119,91,93,32,61,32,123,10,35,101,109,98
and warns on it for -Wunused-value and just compiles it as
[0] = 42, [15] = 98
And also
void foo (int, int, int, int);
void bar (void) { foo (
#embed __FILE__ limit (4) prefix (172 + ) suffix (+ 2)
); }
is treated as
172 + (118, 111, 105, 100) + 2
rather than
172 + 118, 111, 105, 100 + 2
which clang -save-temps or GCC treats it like, so results
in just one argument passed rather than 4.
if (!strstr ((const char *) magna_carta, "imprisonétur")) abort ();
in the testcase fails as well, but in that case calling it in gdb succeeds:
p ((char *(*)(char *, char *))__strstr_sse2) (magna_carta, "imprisonétur")
$2 = 0x555555558d3c <magna_carta+11564> "imprisonétur aut disseisiátur"...
so I guess they are just trying to constant evaluate strstr and do it
incorrectly.
They started with making the optimizations together in the initial patch
set, so they don't have the luxury to compare if it is just because of
the optimization they are trying to do or because that is how the
feature works for them. At least unless they use -save-temps for now.
There is also different behavior between clang and gcc on -M or other
dependency generating options. Seems clang includes the __has_embed
searched files in dependencies, while my patch doesn't. But so does
clang for __has_include and GCC doesn't. Emitting a hard dependency
on some header just because there was __has_include/__has_embed for it
seems wrong to me, because (at least when properly written) the source
likely doesn't mind if the file is missing, it will do something else,
so a hard error from make because of it doesn't seem right. Does
make have some weaker dependencies, such that if some file can be remade
it is but if it doesn't exist, it isn't fatal?
I wonder whether #embed <non-existent-file> really needs to be fatal
or whether we could simply after diagnosing it pretend the file exists
and is empty. For #include I think fatal errors make tons of sense,
but perhaps for #embed which is more localized we'd get better error
reporting if we didn't bail out immediately. Note, both GCC and clang
currently treat those as fatal errors.
clang also added -dE option which with -E instead of preprocessing
the #embed directives keeps them as is, but the preprocessed source
then isn't self-contained. That option looks more harmful than useful to
me.
Also, it isn't clear to me from C23 whether it is possible to have
__has_include/__has_c_attribute/__has_embed expressions inside of
the limit #embed/__has_embed argument.
6.10.3.2/2 says that defined should not appear there (and the patch
diagnoses it and testsuite tests), but for __has_include/__has_embed
etc. 6.10.1/11 says:
"The identifiers __has_include, __has_embed, and __has_c_attribute
shall not appear in any context not mentioned in this subclause."
If that subclause in that case means 6.10.1, then it presumably shouldn't
appear in #embed in 6.10.3, but __has_embed is in 6.10.1...
But 6.10.3.2/3 says that it should be parsed according to the 6.10.1
rules. Haven't included tests like
#if __has_embed (__FILE__ limit (__has_embed (__FILE__ limit (1))))
or
#embed __FILE__ limit (__has_include (__FILE__))
into the testsuite because of the doubts but I think the patch should
handle those right now.
The reason I've used Magna Carta text in some of the testcases is that
I hope it shouldn't be copyrighted after the centuries and I'd strongly
prefer not to have binary blobs in git after the xz backdoor lesson
and wanted something larger which doesn't change all the time.
Oh, BTW, I see in C23 draft 6.10.3.2 in Example 4
if (f_source == NULL);
return 1;
(note the spurious semicolon after closing paren), has that been fixed
already?
Like the thephd.dev and clang implementations, the patch always macro
expands the whole #embed and __has_embed directives except for the
embed keyword. That is most likely not what C23 says, my limited
understanding right now is that in #embed one needs to parse the whole
directive line with macro expansion disabled and check if it satisfies the
grammar, if not, the whole directive is macro expanded, if yes, only
the limit parameter argument is macro expanded and the prefix/suffix/if_empty
arguments are maybe macro expanded when actually used (and not at all if
unused). And I think __has_embed macro expansion has conflicting rules.

We currently ICE upon the following code while building the "[...] is
private within this context" error message
=== cut here ===
class A { enum Enum{}; };
template<typename E, template<typename> class Alloc>
class B : private Alloc<E>, private A {};
template<typename E, template<typename> class Alloc>
int B<E, Alloc>::foo (Enum m) { return 42; }
=== cut here ===
The problem is that since r11-6880, after detecting that Enum cannot be
accessed in B, enforce_access will access the TYPE_BINFO of all the
bases of B, which ICEs for any that is a BOUND_TEMPLATE_TEMPLATE_PARM.
This patch simply skips such bases.

When we decide to not process a association chain of size two and
that would also mismatch with a different chain size on another lane
we shouldn't fail discovery hard at this point. Instead let the
regular discovery figure out matching lanes so the parent can
decide to perform operand swapping or we can split groups at better
points rather than forcefully splitting away the first single lane.
For example on gcc.dg/vect/vect-strided-u8-i8.c we now see two
groups of size 4 feeding the store instead of groups of size 1,
three, two, one and one.

Hi all,
A simple assembly check has been added in this version. Previous version:
https://gcc.gnu.org/pipermail/gcc-patches/2024-September/662783.html
Thanks,
Bohan
------
The current vsetvl pass eliminates a vsetvl instruction when the previous
info is "available," but does not when "compatible." This can lead to not
only redundancy, but also incorrect behaviors when the previous info happens
to be compatible with a later vector instruction, which ends of using the
vsetvl info that should have been eliminated, as is shown in the testcase.
This patch eliminates the vsetvl when the previous info is "compatible."

This patch fixes a bug in the current vsetvl pass. The current pass uses
`m_vl` to determine whether the dest operand has been used by non-RVV
instructions. However, `m_vl` may have been modified as a result of an
`update_avl` call, and thus would be no longer the dest operand of the
original instruction. This can lead to incorrect vsetvl eliminations, as is
shown in the testcase. In this patch, we create a `dest_vl` variable for
this scenerio.

My last fix for this issue (PR c++/114947, r15-810) didn't go far
enough; I had assumed that the issue where we lost track of partial
specialisations we would need to walk again later was limited to
partitions (where we always re-walk all specialisations), but the linked
PR is the same cause but for header units, and it is possible to
construct test cases exposing the same bug just for normal modules.
As such this patch just unconditionally ensures that whenever we modify
DECL_TEMPLATE_SPECIALIZATIONS we also track any partial specialisations
that might have added.
Also clean up a couple of comments and assertions to make expected state
more obvious when processing these specs.
