[Bug tree-optimization/114331] New: Missed optimization: indicate knownbits from dominating condition switch(trunc(a))
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114331
Bug ID: 114331
Summary: Missed optimization: indicate knownbits from
dominating condition switch(trunc(a))
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: xxs_chy at outlook dot com
Target Milestone: ---
Godbolt link: https://godbolt.org/z/dso53ndTo
For code like:
int src(int num) {
switch((short)num){
case 111:
return num & 0xfffe;
case 267:
case 204:
case 263:
return 0;
default:
dummy();
return 0;
}
}
"num & 0xfffe" can be folded to "110". But both LLVM and GCC fail to fold it.

[Bug libgcc/114327] `-CST % 1` is wrong for _BitInt()
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114327
--- Comment #3 from Zdenek Sojka ---
It's not only % 1; wrong results are also for:
B x = foo (3, -0x9e9b9fe60);
or for
B
foo (char c, B b)
{
return b / c;
}
B x = foo (-0x6, 0); /* 0 / -6 = 0 */
in all these cases, the result is the same: -1 << 64.

[Bug driver/114330] needs_preprocessing field of struct compiler is unused
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114330 Andrew Pinski changed: What|Removed |Added Ever confirmed|0 |1 Last reconfirmed||2024-03-14 Status|UNCONFIRMED |ASSIGNED Assignee|unassigned at gcc dot gnu.org |pinskia at gcc dot gnu.org --- Comment #4 from Andrew Pinski --- (In reply to Sam James from comment #2) > git log -G needs_preprocessing -p indicates r0-102965-gc3224d6f70eefb Oh yes when -combine support was removed. It was added in -combine support was added in r0-57561-g0855eab7a30bb9 . combinable field was added at the same time but combinable was used afterwards for go (and D and a few others). So I will handle this for GCC 15. I thought it was added much earlier.
[PATCH] i386[stv]: Handle REG_EH_REGION note
When we split
(insn 37 36 38 10 (set (reg:DI 104 [ _18 ])
(mem:DI (reg/f:SI 98 [ CallNative_nclosure.0_1 ]) [6 MEM[(struct
SQRefCounted *)CallNative_nclosure.0_1]._uiRef+0 S8 A32])) "test.C":22:42 84
{*movdi_internal}
(expr_list:REG_EH_REGION (const_int -11 [0xfff5])
into
(insn 104 36 37 10 (set (subreg:V2DI (reg:DI 124) 0)
(vec_concat:V2DI (mem:DI (reg/f:SI 98 [ CallNative_nclosure.0_1 ]) [6
MEM[(struct SQRefCounted *)CallNative_nclosure.0_1]._uiRef+0 S8 A32])
(const_int 0 [0]))) "test.C":22:42 -1
(nil)))
(insn 37 104 105 10 (set (subreg:V2DI (reg:DI 104 [ _18 ]) 0)
(subreg:V2DI (reg:DI 124) 0)) "test.C":22:42 2024 {movv2di_internal}
(expr_list:REG_EH_REGION (const_int -11 [0xfff5])
(nil)))
we must copy the REG_EH_REGION note to the first insn and split the block
after the newly added insn. The REG_EH_REGION on the second insn will be
removed later since it no longer traps.
Currently we only handle memory_operand, are there any other insns
need to be handled???
Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,} for trunk and
gcc-13/gcc-12 release branch.
Ok for trunk and backport?
gcc/ChangeLog:
* config/i386/i386-features.cc
(general_scalar_chain::convert_op): Handle REG_EH_REGION note.
(convert_scalars_to_vector): Ditto.
* config/i386/i386-features.h (class scalar_chain): New
memeber control_flow_insns.
gcc/testsuite/ChangeLog:
* g++.target/i386/pr111822.C: New test.

[PATCH v2] LoongArch: Remove masking process for operand 3 of xvpermi.q.
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.
This patch partially reverts 7b158e036a95b1ab40793dd53bed7dbd770ffdaf.
gcc/ChangeLog:
* config/loongarch/lasx.md (lasx_xvpermi_q_):
Remove masking of operand 3.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/vector/lasx/lasx-xvpermi_q.c:
Reposition operand 3's value into instruction's defined accept range.

[[gnu::noinline]]
B
foo (signed char c, B b)
{
return b % c;
}
int
main (void)
{
B x = foo (1, -3); // -3 % 1 -> 0
// if (x)
// __builtin_abort();
signed long *t = (signed long *)
for(int i = 0;i < sizeof(B)/sizeof(long); i++ )
{
__builtin_printf("%lx\n", t[i]);
}
return 0;
}
```
We get:
```
0
```
Which makes it seem like we are doing the sign extend when the value was the
result was 0.
Even:
> B x = foo (3, -3); // -3 % 3 -> 0
Gives the wrong similar result.
Builtin for consulting value analysis (better ffs() code gen)
Hello,
I've come across an issue that I would have thought there would be a
builtin for, but perhaps that's just wishful thinking. I'd like to be
able to write something like this:
if (__builtin_expr_is_true(x > 0))
... // one thing
else
... // something else
This stems from trying to clean up the mess of bit operation helpers in Xen.
On x86, __builtin_ffs() doesn't have great code generation. This is a
consequence of the BSF instruction having miserable semantics, and the
builtin emits code with a branch or cmov to compensate for undefined
case of passing 0 in.
On x86_64 at least, Intel and AMD have made enough guarantees in writing
to allow a condition-less form:
mov $-1, %dst
bsf %src, %dst
add $1, %dst
which is good, but not great. It is common to have an __ffs() variant
which states that a src of 0 is undefined, and while this makes a
reasonable improvement to the code generation within loops, it's still
not great to rely on the programmer to get this right.
A common pattern to find is something like:
while (x) {
int b = ffs(x);
... // do something with x and b
where range analysis can know that x is nonzero. Indeed, the builtin
manages to spot this, and emits a condition-less form too.
However, doing this for a local implementation of ffs() doesn't work. With:
unsigned int my_ffs(unsigned int x)
{
int res;
if (x) {
asm ("bsf ..." : "=r" (res) : "rm" (x));
} else {
res = -1;
asm ("bsf ..." : "+r" (res) : "rm" (x));
}
return res + 1;
}
the while() example above really does get generated with ideal form.
However, in general code where the value of x is unknown, the entire
if/else chain is emitted, which is strictly worse than just emitting the
else case which is the safe catch-all.
I suppose that what I'm looking for is something a little like
__builtin_constant_p() which can either be used in a straight if(), or
in a __builtin_choose_expr().
Anyway - is there a way of doing this that I've managed to overlook?

[committed] libstdc++: Move test error_category to global scope
Tested with GDB 14.1 on x86_64-linux. I'll backport this too.
-- >8 --
A recent GDB change causes this test to fail due to missing RTTI for the
custom_cast type. This is presumably because the custom_cat type was
defined as a local class, so has no linkage. Moving it to local scope
seems to fix the test regressions, and probably makes the test more
realistic as a local class with no linkage isn't practical to use as an
error category that almost certainly needs to be referred to in other
scopes.
libstdc++-v3/ChangeLog:
* testsuite/libstdc++-prettyprinters/cxx11.cc: Move custom_cat
to namespace scope.

[Bug driver/114330] New: needs_preprocessing field of struct compiler is unused
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114330 Bug ID: 114330 Summary: needs_preprocessing field of struct compiler is unused Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: internal-improvement Severity: enhancement Priority: P3 Component: driver Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- I suspect needs_preprocessing field became unused when the C preprocessor became itergrated into the cc1. while it does not hurt anything to have the field still around and only the ".c" sets it to true, it seems like a decent idea to remove the field. Also note it might be useful to boolize combinable in struct compiler in gcc.cc too.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108866 Andrew Pinski changed: What|Removed |Added Ever confirmed|0 |1 Last reconfirmed||2024-03-13 Status|UNCONFIRMED |NEW --- Comment #3 from Andrew Pinski --- (In reply to Pali Rohár from comment #2) > Andrew, I do not know what is gcc driver nor what to do for it. But if you > can show me some pointers, I can try it. > > Or if you need more details about files, usage, etc... please let me know. See gcc.cc (default_compilers). It contains a mapping from suffix to language and language and how to "compile/assemble" the files. See also */lang-specs.h which are included via specs.h (specs.h is a generated file while building, see the makefile there and depends on which language is enabled). Most likely you would add a new target macro which adds to that part of the gcc.cc and define that macro in the mingw headers.

Yes it looks like it is pattern matching what I suggested (well with and
without the and).
Note we do need another pattern, one without the bit_and:
(simplify
(bit_ior
(ne@n4 @0 @1)
(cmp
(bit_xor @0 @1)
@2))
(bit_ior @n4
(cmp { build_zero_cst (TREE_TYPE (@0)); } @2))
)
And we need one more for bit_ior:
(simplify
(bit_ior
(ne@n4 @0 @1)
(cmp
(bit_ior
(bit_xor @0 @1)
@2)
@3))
(bit_ior @n4
(cmp @2 @3))
)
Note it looks like clang does not handle non-contants that well, (they handle d
== 0 though).
E.g.:
```
int foo(void);
int cmp1(unsigned d1, unsigned d2, unsigned c, unsigned d) {
int t = ((d1 ^ d2) & c ) == (d);
int t1 = d1 != d2;
int tt = t | t1;
return tt;
}
```
Should be optimized to:
int foo(void);
int cmp1(unsigned d1, unsigned d2, unsigned c, unsigned d) {
int t = 0 == d;
int t1 = d1 != d2;
int tt = t | t1;
return tt;
}
```
[Bug target/108849] __declspec(code_seg("segname")) does not work
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108849
--- Comment #3 from Pali Rohár ---
Arsen, so based on my understooding (please correct me if I'm wrong), gcc's
"section" can be used on both code (functions) and data (global variables). And
ms's "code_seg" can be used only on code (functions).
So if gcc adds __declspec(code_seg("segname")) as alias to
__declspec(section("segname")) for TARGET_DECLSPEC then it should be OK for
valid source code. However it does not throws an compile error if
__declspec(code_seg("segname")) is specified on data. But I think it is
acceptable. Primary motivation is support for compiling valid source code.
Are you able to add this alias?

The regressed testcase looks like its testing if riscv vectorizes the code at
all (the first issue Juzhe noted in comment #3 and then fixed). So this is a
performance regression for risc-v, not correctness.
Re: [PATCH V12]: Improve code sinking pass
On 3/13/24 4:22 AM, Richard Biener wrote: ... this hunk is OK (please test and split it out separatley). In the spirit of moving the stmt the least amount (in this case not schedule it within the basic-block). In the same spirit one would choose an earlier basic-block but only if the old choosen one post-dominates that, dominance isn't a good criteria since you'd move it where the computation might not be needed. A practical testcase would be tem = a + b; if (foo) bar (); tem2 = tem + d; where we at the moment would sink 'tem = a+ b' to the block containing 'tem2 = tem + d' not reducing the number of evaluations (of course bar() might not return, but that's a minor detail). Code motion like that should be subject to register-pressure considerations which we do not estimate here at all. So it could be argued we shouldn't perform any sinking here. Agreed. This looks more like a scheduling and register-pressure issue rather than a classic sinking issue. Sinking is supposed to be moving code to lesser executed points. In the case above, the only way sinking into the tem2 = block would be if bar() doesn't return. It just doesn't make sense to me from a sinking standpoint. The block execution data generally prevents this kind of gratuitous movement. I actually evaluated our sinking code several years ago against an implementation of Click's algorithm. In general they were quite comparable in terms of selecting an "optimal" block from an execution standpoint. There were a couple of fixes that were added to our implementation at that time, but again, generally we were picking sensible blocks. A good first-order heuristic would be to avoid the scheduling when the number of non-virtual SSA uses on the stmt to be moved is bigger than one. For zero we reduce the lifetime of the def. For one we're not making things worse. For more uses it depends on whether we're moving within the lifetime of the uses and it becomes a global problem (we're greedily moving dependent statements, so we even get "local global" wrong then). That said, changing will cause regressions, given both before and after is somewhat ad-hoc it's hard to argue one is more correct than the other. IMO scheduling should be left to a stmt scheduler on GIMPLE (which we don't have). Click's work can function as a statement scheduler, though I'm not convinced it's actually a good one. Essentially most statements are conceptually disassociated from their blocks, then re-scheduled by visiting defining statements of "pinned" instructions. That model is mostly for driving redundancy elimination. Scheduling is just a side effect. Bernd had a statement scheduler for gimple years ago, but it was somewhat controversial at the time and never moved forward enough to get integrated. IIRC it ran just before or just after TER and its primary objective was to avoid some of the pathological cases that ultimately result in significant spilling after we're done with the bulk of the RTL pipeline.

[Bug tree-optimization/113281] [11/12/13 Regression] Latent wrong code due to vectorization of shift reduction and missing promotions since r9-1590

I looked into what the vectorizer produces:
vect__22.13_31 = (vector(8) int) vect_vec_iv_.12_8;
_22 = (int) a.4_25;
vect__12.14_33 = { 32872, 32872, 32872, 32872, 32872, 32872, 32872, 32872 }
>> vect__22.13_31;
_12 = 32872 >> _22;
vect_b_7.15_34 = (vector(8) short int) vect__12.14_33;
that is valid thing to do. That is do the shift in `vector(8) int` and then do
a truncation. The issue originally was about doing the shift in `vector(8)
short` which is not happening here.

It looks like we have a regression for riscv I was going through the scan dump failures on trunk and ended up revisiting https://github.com/patrick-rivos/gcc-postcommit-ci/issues/463 where gcc.dg/vect/costmodel/riscv/rvv/pr113281-[125].c are failing the scan-dump checks.

Interestingly, the remaining part of this bug is also a regression, it just
does not break LAPACK. Reverting this change fixes it which means the new test
for pr105473 will fail. I have an idea where to put this check in
read_complex() but I have not finished this and tested it.
Jeffrey, if you would like me to push this, let me know. We can mark
pr105473.f90 in the test suite to XFAIL or comment out the one check there that
fails.

Confirmed.
Obvious if the first part is false then d1 ^ d2 will be 0.
This will work though maybe there is another place where this can be handled

Re: [PATCH, OpenACC 2.7] struct/array reductions for Fortran
Hi Chung-Lin, hi Thomas, hello world,
some thoughts glancing at the patch.
Chung-Lin Tang wrote:
There is still some shortcomings in the current state, mainly that only explicit-shaped
arrays can be used (like its C counterpart). Anything else is currently a bit more
complicated in the middle-end, since the existing reduction code creates an
"init-op" (literal of initial values) which can't be done when say
TYPE_MAX_VALUE (TYPE_DOMAIN (array_type)) is not a tree constant. I think we'll be on the
hook to solve this later, but I think the current state is okay to submit.
I think having some initial support is fine, but it needs an
understandable and somewhat complete error diagnostic and testcases.
More to this below.
+ if (!TREE_CONSTANT (min_tree) || !TREE_CONSTANT (max_tree))
+ {
+ error_at (loc, "array in reduction must be of constant size");
+ return error_mark_node;
+ }
Shouldn't this use a sorry_at instead?
+ /* OpenACC current only supports array reductions on explicit-shape
+arrays. */
+ if ((n->sym->as && n->sym->as->type != AS_EXPLICIT)
+ || n->sym->attr.codimension)
gfc_error ("Array %qs is not permitted in reduction at %L",
n->sym->name, >where);
[Coarray excursion. I am in favor of allowing it for the reasons above,
but it could be also rejected but I would prefer to have a proper error
message in that case.]
While coarrays are unspecified, I do not see a reason why a corray
shouldn't be permitted here – as long as it is not coindexed. At the
end, it is just a normal array with some additional properties, which
make it possible to remotely access it.
Note: For coarray scalars, we have 'sym->as', thus the check should be
'(n->sym->as && n->sym->as->rank)' to permit scalar coarrays.
* * *
Coarray excursion: A coarray variables exists in multiple processes
("images", e.g. MPI processes). If 'caf' and 'caf2' are coarrays, then
'caf = 5' and 'i = caf2' refer to the local variable.
On the other hand, 'caf[n] = 5' or 'i = caf[3,m]' refers to the 'caf'
variable on image 'n' or [3,m]', respectively, which implies in general
some function call to read or set the remote data, unless the memory is
directly accessible (→ e.g. some offset calculation) and the compiler
already knows how to handle this.
While a coarrary might be allocated in some special memory, as long as
one uses the local version (i.e. not coindexed / without the image index
in brackets).
Assume for the example above, e.g., integer :: caf[*], caf2[3:6, 7:*].
* * *
Thus, in terms of OpenACC or OpenMP, there is no reason to fret a
coarray as long as it is not coindexed and as long as OpenMP/OpenACC
does not interfere with the memory allocation – either directly ('!$omp
allocators') or indirectly by placing it into special memory (pinned,
pseudo-unified-shared memory → OG13's -foffload-memory=pinned/unified).
In the meanwhile, OpenMP actually explicitly allows coarrays with few
exceptions while OpenACC talks about unspecified behavior.
* * *
Back to generic comments:
If I look at the existing code, I see at gfc_match_omp_clause_reduction:
if (gfc_match_omp_variable_list (" :", >lists[list_idx], false, NULL,
, openacc, allow_derived) !=
MATCH_YES)
If 'openacc' is true, array sections are permitted - but the code added
(see quote above) does not handle n->expr at all and only n->sym.
I think there needs to be at least a "gfc_error ("Sorry, subarrays/array
sections not yet handled" [subarray is the OpenACC wording, 'array
section' is the Fortran one, which might be clearer.
But you could consider to handle at least array elements, i.e.
n->expr->rank == 0.
Additionally, I think the current error message is completely unhelpful
given that some arrays are supported but most are not.
I think there should be also some testcases for the not-yet-supported
case. I think the following will trigger the omp-low.cc 'sorry_at' (or
currently 'error' - but I think it should be a sorry):
subroutine foo(n)
integer :: n, A(n)
... reduction(+:A)
And most others will trigger in openmp.cc; for those, you should have an
allocatable/pointer and assumed-shape arrays for the diagnostic testcase
as well.
* * *
I have not really experimented with the code, but does it handle
multi-dimensional constant arrays like 'integer :: a(3:6,10,-1:1)' ? — I
bet it does, at least after handling my example [2] for the C patch [1].
Thanks,
Tobias

Validate that the attribute only applies to a C99 flexible array member of a

verify_counted_by_attribute does more extensive validation on argval.

I promoted range_on_exit and range_on_entry to be part of the API in this
patch. This brings valeu_query in line with rangers basic 5 routine API. It
also tweaks rangers versions to handle tree expressions. It bootstraps and
shows no regressions, with the caveat that I haven't actually tested the usage
of range_on_entry and exit with arbitrary trees. As you can see, I didnt
change much... so it should work OK.

My guess is the latter. Without a context and with that change, ranger
evaluates the definition with the context at the location of the def, then
simply uses that value. If anything it is dependent on later changes, the
temporal cache should indicate it's out of date and trigger a new fold using

Re: [PATCH, OpenACC 2.7] Implement reductions for arrays and structs
Hi Chung-Lin,

(Stumbled over while looking at the Fortran patch, but applying to
C/C++, hence mentioned here; the Fortran patch is at
https://gcc.gnu.org/pipermail/gcc-patches/2024-February/645205.html )
OpenACC permits array elements and subarrays. I have not checked whether
array elements are currently rejected or fully supported, but I miss a
testcase for both array elements (unless there is one already) and array
sections.
If implemented, I think there should be a working run-time test.
If not supported, there should be a sorry_at error for those.
Note: the parser should handle array sections as OpenMP handles them.
The testcase should cover something like the following:
void f(int n)
{
int x[5][5]; // Multimensional array;
int y[n]; // VLA
int *z = (int*)malloc(5*5*sizeof(int)); // Allocated array
... reduction(+:x)
... reduction(+:y)
... reduction(+:x[0:5][2:1]) // OK
... reduction(+:x[1:4][2:1])
// invalid - while contiguous, first dim does not span the whole array
... reduction(+:y[2:2]) // OK
... reduction(+:y[3:]) // OK - same as [3:n-3]
... reduction(+:y[:2]) // OK - same as [0:2]
... reduction(+:z[1:2][1:6]) // OK
And the same where at least one of the const number is replaced by
a variable.
Note: The 'invalid' reduction is fine in terms of being contiguous (last
dimension contains a single element, hence, the dimension before does
not need to span the whole extend) - but OpenACC requires the all
dimensions but the last to span the whole range.
See "2.7.1 Data Specification in Data Clauses" for the subarray description.
I think - if known at compile time - there should be also a diagnostic
if the any dimension but the last does not span the whole range.
Thanks,
Tobias
