This meant that code generating these +instructions typically had to do a shift left by 56 bits to get the count into +the right position. In a future version of the PowerPC architecture, new +variants of these instructions might be added that expect the count to be in +the bottom 8 bits of the GPR register. These patches add this support to GCC +if the user uses the -mcpu=future option. + +I discovered that the code in rs6000-string.cc to generate ISA 3.1 lxvl/stxvl +future lxvll/stxvll instructions would generate these instructions on 32-bit. +However the patterns for these instructions is only done on 64-bit systems.

Author: Michael Meissner

RFC2655-Add saturating subtract built-ins.
This patch adds support for a saturating subtract built-in function that
may be
added to a future PowerPC processor. Note, if it is added, the name of the
built-in function may change before GCC 13 is released. If the name
changes,
we will submit a patch changing the name.
I also added support for providing dense math built-in functions, even
though
at present, we have not added any new built-in functions for dense math.
It is
likely we will want to add new dense math built-in functions as the dense
math
support is fleshed out.
The patches have been tested on both little and big endian systems. Can I
check
it into the master branch?

[gcc(refs/users/meissner/heads/work165-dmf)] RFC2656-Support load/store vector with right length.
https://gcc.gnu.org/g:e3be5e2b224450ef7468af4e04755aa0dc0980ad
commit e3be5e2b224450ef7468af4e04755aa0dc0980ad
Author: Michael Meissner

RFC2656-Support load/store vector with right length.
This patch adds support for new instructions that may be added to the
PowerPC
architecture in the future to enhance the load and store vector with length
instructions.
The current instructions (lxvl, lxvll, stxvl, and stxvll) are inconvient to
use
since the count for the number of bytes must be in the top 8 bits of the GPR
register, instead of the bottom 8 bits. This meant that code generating
these
instructions typically had to do a shift left by 56 bits to get the count
into
the right position. In a future version of the PowerPC architecture, new
variants of these instructions might be added that expect the count to be in
the bottom 8 bits of the GPR register. These patches add this support to
GCC
if the user uses the -mcpu=future option.
I discovered that the code in rs6000-string.cc to generate ISA 3.1
lxvl/stxvl
future lxvll/stxvll instructions would generate these instructions on
32-bit.
However the patterns for these instructions is only done on 64-bit systems.
So
I added a check for 64-bit support before generating the instructions.
The patches have been tested on both little and big endian systems. Can I
check
it into the master branch?

RFC2653-PowerPC: Add support for 1,024 bit DMR registers.
This patch is a prelimianry patch to add the full 1,024 bit dense math
register
(DMRs) for -mcpu=future. The MMA 512-bit accumulators map onto the top of
the
DMR register.
This patch only adds the new 1,024 bit register support. It does not add
support for any instructions that need 1,024 bit registers instead of 512
bit
registers.
I used the new mode 'TDOmode' to be the opaque mode used for 1,024 bit
registers. The 'wD' constraint added in previous patches is used for these
registers. I added support to do load and store of DMRs via the VSX
registers,
since there are no load/store dense math instructions. I added the new
keyword
'__dmr' to create 1,024 bit types that can be loaded into DMRs. At
present, I
don't have aliases for __dmr512 and __dmr1024 that we've discussed
internally.
The patches have been tested on both little and big endian systems. Can I
check
it into the master branch?

This patch changes the assembler instruction names for MMA instructions from the original name used in power10 to the new name when used with the dense math system. I.e. xvf64gerpp becomes dmxvf64gerpp. The assembler will emit the same bits for either spelling. For the non-prefixed MMA instructions, we add a 'dm' prefix in front of the instruction. However, the prefixed instructions have a 'pm' prefix, and we add the 'dm' prefix afterwards. To prevent having two sets of parallel int attributes, we remove the "pm" prefix from the instruction string in the attributes, and add it later, both in the insn name and in the output template. 2024-05-03 Michael Meissner gcc/ * config/rs6000/mma.md (vvi4i4i8): Change the instruction to not have a "pm" prefix.

The MMA subsystem added the notion of accumulator registers as an optional feature of ISA 3.1 (power10). In ISA 3.1, these accumulators overlapped with the VSX registers 0..31, but logically the accumulator registers were separate from the FPR registers. In ISA 3.1, it was anticipated that in future systems, the accumulator registers may no overlap with the FPR registers. This patch adds the support for dense math registers as separate registers. This particular patch does not change the MMA support to use the accumulators within the dense math registers. This patch just adds the basic support for having separate DMRs. The next patch will switch the MMA support to use the accumulators if -mcpu=future is used. For testing purposes, I added an undocumented option '-mdense-math' to enable or disable the dense math support. This patch adds a new constraint (wD). If MMA is selected but dense math is not selected (i.e. -mcpu=power10), the wD constraint will allow access to accumulators that overlap with VSX registers 0..31. If both MMA and dense math are selected (i.e. -mcpu=future), the wD constraint will only allow dense math registers. This patch modifies the existing %A output modifier. If MMA is selected but dense math is not selected, then %A output modifier converts the VSX register number to the accumulator number, by dividing it by 4. If both MMA and dense math are selected, then %A will map the separate DMR registers into 0..7. The intention is that user code using extended asm can be modified to run on both MMA without dense math and MMA with dense math: 1) If possible, don't use extended asm, but instead use the MMA built-in functions; 2) If you do need to write extended asm, change the d constraints targetting accumulators should now use wD; 3) Only use the built-in zero, assemble and disassemble functions create move data between vector quad types and dense math accumulators. I.e. do not use the xxmfacc, xxmtacc, and xxsetaccz directly in the extended asm code. The reason is these instructions assume there is a 1-to-1 correspondence between 4 adjacent FPR registers and an accumulator that overlaps with those instructions. With accumulators now being separate registers, there no longer is a 1-to-1 correspondence. It is possible that the mangling for DMRs and the GDB register numbers may produce other changes in the future. 2024-05-03 Michael Meissner * config/rs6000/mma.md (UNSPEC_MMA_DMSETDMRZ): New unspec.

[gcc(refs/users/meissner/heads/work165-dmf)] RFC2653-Add wD constraint.
https://gcc.gnu.org/g:d2cb7b48c27f62f4508716ac9428f1466b0dd810
commit d2cb7b48c27f62f4508716ac9428f1466b0dd810
Author: Michael Meissner
Date: Fri May 3 20:13:14 2024 -0400
RFC2653-Add wD constraint.
This patch adds a new constraint ('wD') that matches the accumulator
registers
that overlap with VSX registers 0..31 on power10. Future patches will add
the
support for a separate accumulator register class that will be used when the
support for dense math registes is added.

Yes, yes that would be definitely better. Let me see if I can figure
that out. I might not be able to get back to this until June though.

[gcc r15-139] Fix printing COMPOUND_EXPR in .original [PR23872]
https://gcc.gnu.org/g:04f24e44fb14a22516444f70503719f3fda15d6c
commit r15-139-g04f24e44fb14a22516444f70503719f3fda15d6c
Author: Andrew Pinski
Date: Tue Apr 16 17:43:36 2024 -0700
Fix printing COMPOUND_EXPR in .original [PR23872]
Starting with the merge of the openmp branch into the trunk
(r0-73077-g953ff28998b59b), COMPOUND_EXPR started to be printed
as `expr; , expr` which is wrong. This was due to the wrong
conversion of dumping_stmts into `!(flags & TDF_SLIM)`. That is wrong
as we are not dumping stmts at this point (`!(flags & TDF_SLIM)` was always
true for this case as TDF_SLIM case was handled before hand). So switch it
to be always false.
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
PR middle-end/23872
* tree-pretty-print.cc (dump_generic_node ): Fix
calls to dump_generic_node and also remove unreachable code that is
testing
`flags & TDF_SLIM`.
gcc/testsuite/ChangeLog:
* gfortran.dg/gomp/atomic-21.f90: Update testcase for the removal
of `;`.

[Bug middle-end/23872] .original dump weirdness
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=23872 --- Comment #11 from GCC Commits --- The trunk branch has been updated by Andrew Pinski : https://gcc.gnu.org/g:04f24e44fb14a22516444f70503719f3fda15d6c commit r15-139-g04f24e44fb14a22516444f70503719f3fda15d6c Author: Andrew Pinski Date: Tue Apr 16 17:43:36 2024 -0700 Fix printing COMPOUND_EXPR in .original [PR23872] Starting with the merge of the openmp branch into the trunk (r0-73077-g953ff28998b59b), COMPOUND_EXPR started to be printed as `expr; , expr` which is wrong. This was due to the wrong conversion of dumping_stmts into `!(flags & TDF_SLIM)`. That is wrong as we are not dumping stmts at this point (`!(flags & TDF_SLIM)` was always true for this case as TDF_SLIM case was handled before hand). So switch it to be always false. Bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/ChangeLog: PR middle-end/23872 * tree-pretty-print.cc (dump_generic_node ): Fix calls to dump_generic_node and also remove unreachable code that is testing `flags & TDF_SLIM`. gcc/testsuite/ChangeLog: * gfortran.dg/gomp/atomic-21.f90: Update testcase for the removal of `;`.

[PATCH, obvious] Fix for ICE in tree-nested.cc
I'm planning to push the attached patch to mainline in a couple days, unless someone disputes that it's "obvious" or has some other objection. I think it qualifies because the code immediately following the loop with the bad initializer is already conditionalized on GIMPLE_OMP_TARGET in the same way. I think this patch is a candidate for backporting to the GCC 14 branch once it is unfrozen after the release, too. -SandraFrom 001d166819525dcef43b980298c2f85af77cd8ad Mon Sep 17 00:00:00 2001 From: Sandra Loosemore Date: Mon, 22 Apr 2024 18:24:25 + Subject: [PATCH, obvious] OpenMP: Fix for ICE in tree-nested.cc.

This makes it sound like there is some code alignment issue going on or a branch misprediction issue going on. bad alignment: 4aeae4 good alignment 4aec44 The good alignment case is at the (almost) start at an icache line while the bad alignment case is in the middle. (I am assuming 64byte cache lines which I think is correct) Maybe look at mispredicted branches too. It might be the branch leading to this code is being mispredicted more due to the address of the branch is now interfeeing with another branch. It might just have been bad luck that caused this regression in both cases really; alignment differences and/or address differences can be bad luck.

Re: [PATCH v2 6/6] bpf,btf: enable BTF pruning by default for BPF

This patch enables -fprune-btf by default in the BPF backend when
generating BTF information, and fixes BPF CO-RE generation when using
-fprune-btf.
When generating BPF CO-RE information, we must ensure that types used
in CO-RE relocations always have sufficient BTF information emited so
that the CO-RE relocations can be processed by a BPF loader. The BTF
pruning algorithm on its own does not have sufficient information to
determine which types are used in a BPF CO-RE relocation, so this
information must be supplied by the BPF backend, using a new
btf_mark_type_used function.

Re: [PATCH v2 5/6] btf: add -fprune-btf option
On 5/2/24 10:11, David Faust wrote:
This patch adds a new option, -fprune-btf, to control BTF debug info
generation.
As the name implies, this option enables a kind of "pruning" of the BTF
information before it is emitted. When enabled, rather than emitting
all type information translated from DWARF, only information for types
directly used in the source program is emitted.
The primary purpose of this pruning is to reduce the amount of
unnecessary BTF information emitted, especially for BPF programs. It is
very common for BPF programs to incldue Linux kernel internal headers in
order to have access to kernel data structures. However, doing so often
has the side effect of also adding type definitions for a large number
of types which are not actually used by nor relevant to the program.
In these cases, -fprune-btf commonly reduces the size of the resulting
BTF information by approximately 10x. This both slims down the size of
the resulting object and reduces the time required by the BPF loader to
verify the program and its BTF information.
The 10x reduction is substantial. Do you think its is worthwhile to
mention alongside that this data is the average observed for the kernel
self-tests (I assume it is) ? Just useful info when parsing the commit
logs, especially when some data is specified...
Note that the pruning implemented in this patch follows the same rules
as the BTF pruning performed unconditionally by LLVM's BPF backend when
generating BTF. In particular, the main sources of pruning are:
1) Only generate BTF for types used by variables and functions at
the file scope.
I dont recollect anymore if BTF_KIND_VAR for unused static vars is also
a correctness issue for BTF. (With PR debug/113566, we know having
BTF_KIND_DATASEC entries for optimized away vars is an issue).
It will be great to add some text here or elsewhere for posterity around
this.
2) Avoid emitting full BTF for struct and union types which are only
pointed-to by members of other struct/union types. In these cases,
the full BTF_KIND_STRUCT or BTF_KIND_UNION which would normally
be emitted is replaced with a BTF_KIND_FWD, as though the
underlying type was a forward-declared struct or union type.

Re: [PATCH v2 4/6] btf: refactor and simplify implementation
On 5/2/24 10:11, David Faust wrote: This patch heavily refactors btfout.cc to take advantage of the structural changes in the prior commits. Now that inter-type references are internally stored as simply pointers, all the painful, brittle, confusing infrastructure that was used in the process of converting CTF type IDs to BTF type IDs can be thrown out. This greatly simplifies the entire process of converting from CTF to BTF, making the code cleaner, easier to read, and easier to maintain. In addition, we no longer need to worry about destructive changes in internal data structures used commonly by CTF and BTF, which allows deleting several ancillary data structures previously used in btfout.cc. This is nearly transparent, but a few improvements have also been made: 1) BTF_KIND_FUNC records are now _always_ constructed at early_finish, allowing us to construct records even for functions which are later inlined by optimizations. DATASEC entries for functions are only constructed at late_finish, to avoid incorrectly generating entries for functions which get inlined. 2) BTF_KIND_VAR records and DATASEC entries for them are now always constructed at (late) finish, which avoids cases where we could incorrectly create records for variables which were completely optimized away. This fixes PR debug/113566. I am a bit unsure ATM, how this commit will look like once we revisit where the BTF is generated for BPF and non-BPF backends. Since patch 1/6 moved everything to (late)finish, but that will be problematic, I would like to defer reviewing this until the approach for afore-mentioned patch is pinned. 3) Some additional assembler comments have been added with more information for debugging. gcc/ * btfout.cc (struct btf_datasec_entry): New.

Re: [PATCH v2 1/6] ctf, btf: restructure CTF/BTF emission
On 5/2/24 10:11, David Faust wrote:
This commit makes some structural changes to the CTF/BTF debug info
emission. In particular:
a) CTF is new always fully generated and emitted before any
BTF-related procedures are run. This means that BTF-related
functions can change, even irreversibly, the shared in-memory
representation used by the two formats without issue.
b) BTF generation has fewer entry points, and is cleanly divided
into early_finish and finish.
c) BTF is now always emitted at finish (called from dwarf2out_finish),
rather than being emitted at early_finish for targets other than
BPF CO-RE. Note that this change alone does not alter the contents
of BTF at all, regardless of whether it would have previously been
emitted at early_finish or finish.
This will necessitate that we disallow -gbtf with -flto for non-BPF
targets. Emitting BTF always at dwarf2out_finish will not work with LTO.
The changes are transparent to both CTF and BTF emission.

Second GCC 14.1 Release Candidate available from gcc.gnu.org
The second release candidate for GCC 14.1 is available from https://gcc.gnu.org/pub/gcc/snapshots/14.1.0-RC-20240503/ ftp://gcc.gnu.org/pub/gcc/snapshots/14.1.0-RC-20240503/ and shortly its mirrors. It has been generated from git commit r14-10165-g3b4d6b6ecd79df790. The https://gcc.gnu.org/PR114935 bug has been reported and determined a release blocker, so we'd like to get extra testing on it prior to the release. I have so far bootstrapped and tested the release candidate on x86_64-linux. Please test it and report any issues to bugzilla. If all goes well, we'd still like to release 14.1 on Tuesday, May 7th.

[Bug c/114938] Function argument column info seems to have been lost

--- Comment #2 from Andrew Pinski ---
Take the reduced testcase we get using the C front-end:
```
int proc_dostring (struct ctl_table * table, int write, void * buffer, int *
lenp, int * ppos)
[/app/example.cpp:13:1] {
int D.2793;
[/app/example.cpp:14:5] if (write != 0) goto ; else goto ;
:
[/app/example.cpp:15:3] proc_first_pos_non_zero_ignore (ppos, table);
:
[/app/example.cpp:17:9] _1 = [/app/example.cpp:17:9] table->maxlen;
[/app/example.cpp:17:9] _2 = [/app/example.cpp:17:9] table->data;
[/app/example.cpp:17:9] D.2793 = _proc_do_string (_2, _1, write, buffer,
lenp, ppos);
[/app/example.cpp:17:9] return D.2793;
}
```
The column 9 is the start of the call. But really the first statement should
have a column of 24.
Note with the C++ FE we get:
[/app/example.cpp:17:24] _1 = [/app/example.cpp:17:24] table->maxlen;
[/app/example.cpp:17:24] _2 = [/app/example.cpp:17:24] table->data;
[/app/example.cpp:17:24] D.2822 = _proc_do_string (_2, _1, write, buffer,
lenp, ppos);
[/app/example.cpp:17:24 discrim 1] D.2820 = D.2822;
the :24 is the column after `(`.
But _2 statement really should be the column after the first `,`.
I remember seeing this before ...

The first one is the testcase fails on arm-linux-eabi since it uses __eabi_atexit rather than __cxa_atexit (I think the order of arguments for that function is slightly different too). The second one is making sure the function will bind locally (or the user had the attribute on the function). I should have a new patch Monday or Tuesday. Thanks, Andrew Pinski > jeff
[Bug libbacktrace/114941] libbacktrace build is broken for FDPIC uclibc targets by r14-5173-g2b64e4a54042
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114941 --- Comment #1 from Andrew Pinski --- So a patch like what was done in r0-56719-g34208acf14fa02 needs to be done to libbacktrace . Basically this has always been broken.
[Bug libbacktrace/114941] New: libbacktrace build is broken for FDPIC uclibc targets by gcc-14-5173-g2b64e4a54042
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114941
Bug ID: 114941
Summary: libbacktrace build is broken for FDPIC uclibc targets
by gcc-14-5173-g2b64e4a54042
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libbacktrace
Assignee: unassigned at gcc dot gnu.org
Reporter: jcmvbkbc at gcc dot gnu.org
CC: ian at gcc dot gnu.org
Target Milestone: ---
A fix for the https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111315 turned on the
use of the dl_iterate_phdr interface in the libbacktrace, but since the type of
the dl_phdr_info::dlpi_addr on FDPIC targets using uclibc is not compatible
with uintptr_t the libstdc++-v3 build breaks for these targets with the
following message:
elf.c:7372:62: error: incompatible type for argument 6 of ‘elf_add’
7372 | if (elf_add (pd->state, filename, descriptor, NULL, 0,
info->dlpi_addr,
|
^~~
| |
| struct
elf32_fdpic_loadaddr
elf.c:6504:20: note: expected ‘uintptr_t’ {aka ‘unsigned int’} but argument is
of type ‘struct elf32_fdpic_loadaddr’

Yeah, I agree. Since -fsized-deallocation is not the default behavior of clang++, reporting errors in seems strange.

But if the array is a temporary, or a subobject of one, the array cleanup region lasts for the rest of the full-expression, along with the normal cleanup for the TARGET_EXPR. As a result, when tata throws we clean it up twice. Before r14-1705 we avoided this by disabling the array cleanup in split_nonconstant_init, but after that we don't go through split_nonconstant_init, so let's handle it in cp_genericize_target_expr.

[Bug libstdc++/114940] std::generator relies on an optional overload of operator delete
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114940 --- Comment #3 from Jonathan Wakely --- P.S. what's optional is whether the compiler chooses to use that overload or not. But its presence is required for conformance.

Failing to provide it is non-conforming, although GCC can be requested to be non-conforming the same way with -fno-sized-deallocation. Using that, the same error happens with GCC. We should either disable __cpp_lib_generator when __cpp_sized_deallocation is not defined, or change to not depend on it unconditionally.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114940 --- Comment #1 from Timothy Liu Xuefeng --- It seems that passing -fsized-deallocation to clang++ can resolve this problem. But it seems that it's not the default behavior.
[PATCH] AARCH64: Add Qualcomnm oryon-1 core
This patch adds Qualcomm's new oryon-1 core; this is enough
to recongize the core and later on will add the tuning structure.
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (oryon-1): New entry.
* config/aarch64/aarch64-tune.md: Regenerate.
* doc/invoke.texi (AArch64 Options): Document oryon-1.

It would be better to call ct.narrow(0, 0, 0, 0) as that will populate the
_M_narrow array and also set the _M_narrow_ok flag. Otherwise you can still get
later races on the flag.
[Bug libstdc++/114940] New: std::generator relies on an optional overload of operator delete
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114940
Bug ID: 114940
Summary: std::generator relies on an optional overload of
operator delete
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: liuxf19 at 163 dot com
Target Milestone: ---
The bug report #114891 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114891
discussed the impact of is_pointer_interconvertible_base_of_v on using
std::generator with clang++ and libstdc++. There's another issue when
std::generator in libstdc++ is used by other compilers such as clang++.
In the header , an overload of operator delete:
void operator delete ( void* ptr, std::size_t sz ) noexcept;
However, this is an OPTIONAL feature whose feature test macro is
__cpp_sized_deallocation macro. Some compilers especially clang++, even the
newest clang trunk (which is avaiable at https://godbolt.org, and the version
is 19.0.0) didn't implement this macro. For example, the code below:
#include
int main() {
#ifndef __cpp_sized_deallocation
static_assert(false, "no __cpp_sized_deallocation");
#endif
}
compiled with: clang++ -std=c++23 -stdlib=libstdc++
will cause the following errors:
:5:19: error: static assertion failed: no __cpp_sized_deallocation
5 | static_assert(false, "no __cpp_sized_deallocation");
| ^
1 error generated.
ASM generation compiler returned: 1
:5:19: error: static assertion failed: no __cpp_sized_deallocation
5 | static_assert(false, "no __cpp_sized_deallocation");
| ^
1 error generated.
See https://gcc.godbolt.org/z/MocWxMKz6 for details.
And thus there's no this overload with clang++.
But the std::generator in libstdc++ relies on this overload, which also causes
clang++ cannot use std::generator in libstdc++ (even after clang++ 19 provided
is_pointer_interconvertible_base_of discussed in #114891).
The following code:
#include
#include
std::generator iota(int n) {
for (int i = 0; i < n; ++i) {
co_yield i;
}
}
int main() {
for (auto i : iota(10)) {
}
return 0;
}
compiled with: clang++ -std=c++23 -stdlib=libstdc++
And the compilation errors:
In file included from main.cpp:16:
/usr/bin/../lib/gcc/x86_64-linux-gnu/14/../../../../include/c++/14/generator:606:6:
error: no matching function for call to 'operator delete'
606 | ::operator delete(__ptr, _M_alloc_size(__sz));
| ^
See https://gcc.godbolt.org/z/xjMGaq36a for details.
Note that there's no restrictions that std::generator must depends on this
overload of operator delete in ISO C++. This may cause clang++ or other
compilers cannot use std::generator in libstdc++.
