--- Comment #3 from uecker at gcc dot gnu.org ---
Seems something still needs to be done regarding function types when the
TYPE_CANONICAL is set when completing the struct, see PR114574

[Bug tree-optimization/114932] New: Improvement in CHREC can give large performance gains

2024-05-02 Thread tnfchris at gcc dot gnu.org via Gcc-bugs

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114932

Bug ID: 114932
   Summary: Improvement in CHREC can give large performance gains
   Product: gcc
   Version: 14.0
Status: UNCONFIRMED
  Keywords: missed-optimization
  Severity: normal
  Priority: P3
 Component: tree-optimization
  Assignee: unassigned at gcc dot gnu.org
  Reporter: tnfchris at gcc dot gnu.org
CC: rguenth at gcc dot gnu.org
  Target Milestone: ---

With the original fix from PR114074 applied (e.g.
g:a0b1798042d033fd2cc2c806afbb77875dd2909b) we not only saw regressions but saw
big improvements.

The following testcase:

---
  module brute_force
integer, parameter :: r=9
 integer  block(r, r, r)
contains
  subroutine brute
  k = 1
call digits_2(k)
  end
   recursive subroutine digits_2(row)
  integer, intent(in) :: row
  logical OK
 do i1 = 0, 1
  do i2 = 1, 1
  do i3 = 1, 1
   do i4 = 0, 1
do i5 = 1, select
 do i6 = 0, 1
 do i7 = l0, u0
   select case(1 )
   case(1)
   block(:2, 7:, i7) = block(:2, 7:, i7) - 1
   end select
do i8 = 1, 1
   do i9 = 1, 1
if(row == 5) then
  elseif(OK)then
call digits_2(row + 1)
end if
end do
  end do
   block(:, 1, i7) =   select
end do
end do
  end do
  end do
   end do
block = 1
 end do
 block = 1
 block = block0 + select
  end do
 end
  end
---

compiled with: -mcpu=neoverse-v1 -Ofast -fomit-frame-pointer foo.f90

gets vectorized after sra and constprop.  But the final addressing modes are so
complicated that IVopts generates a register offset mode:

  4c:   2f00041dmvniv29.2s, #0x0
  50:   fc666842ldr d2, [x2, x6]
  54:   fc656841ldr d1, [x2, x5]
  58:   fc646840ldr d0, [x2, x4]
  5c:   0ebd8442add v2.2s, v2.2s, v29.2s
  60:   0ebd8421add v1.2s, v1.2s, v29.2s
  64:   0ebd8400add v0.2s, v0.2s, v29.2s

which is harder for prefetchers to follow.  When the patch was applied it was
able to correctly lower these to the immediate offset loads that the scalar
code was using:

  38:   2f00041dmvniv29.2s, #0x0
  34:   fc594002ldurd2, [x0, #-108]
  40:   fc5b8001ldurd1, [x0, #-72]
  44:   fc5dc000ldurd0, [x0, #-36]
  48:   0ebd8442add v2.2s, v2.2s, v29.2s
  4c:   0ebd8421add v1.2s, v1.2s, v29.2s
  50:   0ebd8400add v0.2s, v0.2s, v29.2s

and also removes all the additional instructions to keep x6,x5 and x4 up to
date.

This gave 10%+ improvements on various workloads.

(ps I'm looking at the __brute_force_MOD_digits_2.constprop.3.isra.0
specialization).

I will try to reduce it more, but am filing this so we can keep track and
hopefully fix.

Asking for HELP

2024-05-02 Thread Jora Gevorgyan via Gcc

Hi! I'm trying to modify the GCC source code to get something done. But
there's a difficulty in understanding how to use some functions and data
structures. Please help me with some hints.

Here is the problem: in the file GCC-source/gcc/c/c-decl.c, before
'c_decl_attributes' is called in 'start_function', I want to insert some
additional optimize attributes in 'attributes' tree to be proceed, but I
could not find the correct way to insert a new tree in it.
 Thanks in advance.

My experience is the exact opposite.  As I'm sure you know, Gerritt
supports specific comments on a code review, and discussions on those
comments are tracked separately.  For a complex patch, or series of
patches, you don't get lost in lots of separate discussions, as Gerritt
tracks them all for you separately.

But it's true that to use that effectively you have to look at the web
interface.  The comments are available via git commands, but not in a
directly usable format.

It will involve the struct TclStubs too. I suspect it does not have its
aliasing set correctly.

Subject: [PATCH v3] DSE: Fix ICE after allow vector type in get_stored_val

From: Pan Li 

We allowed vector type for get_stored_val when read is less than or
equal to store in previous.  Unfortunately,  the valididate_subreg
treats the vector type's size is less than vector register as
invalid.  Then we will have ICE here.

This patch would like to fix it by filter-out the invalid type size,
and make sure the subreg is valid for both the read_mode and store_mode
before perform the real gen_lowpart.

The below test suites are passed for this patch:

* The x86 bootstrap test.
* The x86 regression test.
* The riscv rv64gcv regression test.
* The riscv rv64gc regression test.
* The aarch64 regression test.

gcc/ChangeLog:

* dse.cc (get_stored_val): Make sure read_mode size is greater
than or equal to the vector register size before gen_lowpart.

gcc/testsuite/ChangeLog:

* gcc.target/riscv/rvv/base/pr111720-10.c: Adjust asm checker.
* gcc.target/riscv/rvv/base/bug-6.c: New test.

Thanks. Got it, will have a try isel for scalar and remove the simplify in 
match.md.

No, The isel would only be for the scalar, The vectorizer will still use the 
vect_pattern.
It needs to so we can cost the operation correctly, and in some cases depending 
on how
the saturation is described you are unable the vectorize.  The pattern allows 
us to catch
these cases and still vectorize.

But you should be able to use the same match.pd predicate for both the 
vectorizer pattern
and isel.

Yeah, it looks like this transformation is done in widening_mul, which is the 
other
place richi suggested to recognize SAT_ADD.  widening_mul already runs quite
late as well so it's also ok.

If you put it there before the code that transforms the sequence to overflow it
should work.

Eventually we do need to recognize this variant since:

uint64_t
add_sat(uint64_t x, uint64_t y) noexcept
{
uint64_t z;
if (!__builtin_add_overflow(x, y, ))
return z;
return -1u;
}

Is a valid and common way to do saturation too.

But for now, it's fine.

Cheers,
Tamar

c++: remove lookup_template_class's entering_scope flag

lookup_template_class's entering_scope flag controls whether to prefer
returning the primary template type A instead of the corresponding
implicit instantiation A.  When we want to set this flag as part of
substitution, we need to use tsubst_aggr_type which also takes this flag
as a parameter.  But having this separate entry point to type substitution
turned out to be subtly problematic because it doesn't reuse typedefs
like tsubst does, which r13-4729-gbe124477b38a71 fixed in a way that
respects the flag after the fact, by adjusting the entering_scope=false
result of lookup_template_class as if entering_scope=true was passed.

But if that's possible then it means lookup_template_class's
entering_scope flag is not necessary after all -- we can just do the
after-the-fact adjustment everywhere that we currently pass
entering_scope=true to it and tsubst_aggr_type.

To that end, this patch replaces this flag with an adjustment function
adjust_type_for_entering_scope, to be used whereever we currently need
the entering_scope=true behavior.  In turn we can get rid of
tsubst_aggr_type since the only reason we needed this entry point
was to be able to pass entering_scope=true to lookup_template_class.

lookup_template_class.

[Bug middle-end/114923] gcc ignores escaping pointer and applies invalid optimization

2024-05-02 Thread nfxjfg at googlemail dot com via Gcc-bugs

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114923

--- Comment #9 from nfxjfg at googlemail dot com ---
Oh, I completely missed that your statement was restricted to "in HW". Normally
there are mechanisms in place that make all CPU-level memory accesses to
registers strictly ordered. (In our hardware that is also the case.) I panicked
because you seemed to imply that even the compiler can reorder accesses to reg1
and reg2, but this isn't the case according to you, the gcc docs, and maybe the
standard. Sorry about that.

I suppose it's regrettable that C and gcc do not consider the possibility that
passing an address to a register (which volatile is pretty much the only useful
thing for) does not imply that the memory at that address may change. But that
seems to be the conclusion here.

PR modula2/114929 for loop fails to iterate down to zero when using a 
cardinal type

There is a bug in the for loop control code which is exposed when an
unsigned type is used in the iterator variable.  See
gm2/pim/run/pass/testforloopzero[234].mod.  The bug is in the
calculation of the last iterator value.  The bug fix is to avoid using
negative expressions when calculating the last iterator value with a
negative step value.  This patch detects if e1, e2, step value are all
constant, in which case the ztype is used internally and there is no
overflow.  If the last iterator value is held in a variable then it
uses a different method to calculate the last iterator depending upon
the sign of the step value.

I'm not adding -Os anywhere, just taking defaults.
Confirmed that adding --enable-target-optspace triggers the assembler error.

Yes you need to use inline-asm to get a hw write barrier.
This has been this way for the last 20+ years even when it comes to out of
order processors. 

https://www.puppetmastertrading.com/images/hwViewForSwHackers.pdf should be
very useful. Basically volatile means the compiler not to remove the store/load
from it but it does not mean the HW will reorder the stores/loads. 

Oh and GCC even documents part of this:
https://gcc.gnu.org/onlinedocs/gcc/Volatiles.html

"Accesses to non-volatile objects are not ordered with respect to volatile
accesses. You cannot use a volatile object as a memory barrier to order a
sequence of writes to non-volatile memory. "

The documentation does not mention hw memory barriers since that is outside of
the compiler view really. This has been standard behavior with GCC and hardware
with weak memory systems for over 20 years.

That is even if GCC outputs the writes in order in the assembly the hardware
(or future hardware depending on the definition of the hardware) might reorder
the writes. RISCV IIRC has both a weak and strong memory consistency models.
https://riscv.org/wp-content/uploads/2018/05/14.25-15.00-RISCVMemoryModelTutorial.pdf
for more details on it. GCC will never output the needed instructions directly.

[committed][RISC-V] Fix nearbyint failure on rv32 and formatting nits

2024-05-02 Thread Jeff Law

The CI system tripped an execution failure for rv32 with the ceil/round 
patch.


The fundamental problem is the FP->INT step in these sequences requires 
the input size to match the output size.  The output size was based on 
rv32/rv64.  Meaning that we'd try to do DF->SI->DF.


That doesn't preserve the semantics we want in at least two ways.

The net is we can't use this trick for DF values on rv32.  While inside 
the code I realized we had a similar problem for HF modes.  HF modes we 
can support only for Zfa.  So I fixed that proactively.


The CI system also pointed out various formatting nits.  I think this 
fixes all but one overly long line.


Note I could have factored the TARGET_ZFA test.  But I think as-written 
it's clearer what the desired cases to transform are.


Tested on rv32gcv which verified the failing test passes again.

Pushed to the trunk.

[committed][RISC-V] Fix nearbyint failure on rv32 and formatting nits

The CI system tripped an execution failure for rv32 with the ceil/round 
patch.

The fundamental problem is the FP->INT step in these sequences requires the
input size to match the output size.  The output size was based on 
rv32/rv64.
Meaning that we'd try to do DF->SI->DF.

That doesn't preserve the semantics we want in at least two ways.

The net is we can't use this trick for DF values on rv32.  While inside the
code I realized we had a similar problem for HF modes.  HF modes we can 
support
only for Zfa.  So I fixed that proactively.

The CI system also pointed out various formatting nits.  I think this fixes 
all
but one overly long line.

Note I could have factored the TARGET_ZFA test.  But I think as-written it's
clearer what the desired cases to transform are.

* config/riscv/riscv.md (2): Adjust
condition to match what can be properly implemented.  Fix various
formatting issues.

Gerrit uses "Change-Id:" as stable identifiers to track patches.
https://gregoryszorc.com/blog/2020/01/07/problems-with-pull-requests-and-how-to-fix-them/
has some analysis how they are much better than the alternative smart way.

Perhaps URLs as stable identifiers will work better.
If a reader wants to find relevant discussions, they can just click
the link in many browsers, terminals, and editors.

Currently, searching for discussions about a specific commit requires
searching its title on https://inbox.sourceware.org/gcc-patches/ .
For older patches, I might even need to dig through
https://gcc.gnu.org/pipermail/gcc-patches/-/ archives.

I agree with Jeff that principal reviewers will drive improvement to
the code review process.
I am sharing two code review services LLVM has used.

---

Between 2012 and Sep 2023, LLVM had relied on its self-hosted
Phabricator instance for code review.
Fetching a patch to your local branch was as simple as `arc patch D12345`.
Similarly, creating or updating a patch involved `arc diff`.

I believe other code review services provide similar command line functionality,

---

In September 2023, LLVM transitioned to GitHub for code review.
I really dislike its code review service (however, this is a large
step forward than email based code review). From

Thankfully, getcord/spr comes to a rescue.
User branches allow me to create/update a patch using `spr diff` like
`arc diff` for Phabricator.

rs6000: Add OPTION_MASK_POWER8 [PR101865]

The bug in PR101865 is the _ARCH_PWR8 predefine macro is conditional upon
TARGET_DIRECT_MOVE, which can be false for some -mcpu=power8 compiles if the
-mno-altivec or -mno-vsx options are used.  The solution here is to create
a new OPTION_MASK_POWER8 mask that is true for -mcpu=power8, regardless of
Altivec or VSX enablement.

Unfortunately, the only way to create an OPTION_MASK_* mask is to create
a new option, which we have done here, but marked it as WarnRemoved since
we do not want users using it.  For stage1, we will look into how we can
create ISA mask flags for use in the compiler without the need for explicit
options.

This is a cleanup patch in preparation to fixing the real bug in PR101865.
TARGET_DIRECT_MOVE is redundant with TARGET_P8_VECTOR, so alias it to that.
Also replace all usages of OPTION_MASK_DIRECT_MOVE with 
OPTION_MASK_P8_VECTOR

rs6000: Add OPTION_MASK_POWER8 [PR101865]

The bug in PR101865 is the _ARCH_PWR8 predefine macro is conditional upon
TARGET_DIRECT_MOVE, which can be false for some -mcpu=power8 compiles if
the
-mno-altivec or -mno-vsx options are used.  The solution here is to create
a new OPTION_MASK_POWER8 mask that is true for -mcpu=power8, regardless of
Altivec or VSX enablement.

Unfortunately, the only way to create an OPTION_MASK_* mask is to create
a new option, which we have done here, but marked it as WarnRemoved since
we do not want users using it.  For stage1, we will look into how we can
create ISA mask flags for use in the compiler without the need for explicit
options.

rs6000: Replace OPTION_MASK_DIRECT_MOVE with OPTION_MASK_P8_VECTOR
[PR101865]

This is a cleanup patch in preparation to fixing the real bug in PR101865.
TARGET_DIRECT_MOVE is redundant with TARGET_P8_VECTOR, so alias it to that.
Also replace all usages of OPTION_MASK_DIRECT_MOVE with
OPTION_MASK_P8_VECTOR
and delete the now dead mask.

[Bug middle-end/114923] gcc ignores escaping pointer and applies invalid optimization

2024-05-02 Thread nfxjfg at googlemail dot com via Gcc-bugs

Seriously? That breaks literally all code that uses volatile for register
access (which, in our firmwares, is ALL code). This just fuels my belief that
gcc and C compiler developers in general turned C into a useless, fragile
language that can't do anything correctly.

Is there a way to prevent reordering of volatile accesses?

[Bug c++/114928] New: #pragma packed(push,1) should give the same warning as attribute((packed))

2024-05-02 Thread dhylands at gmail dot com via Gcc-bugs

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114928

Bug ID: 114928
   Summary: #pragma packed(push,1) should give the same warning as
__attribute__((packed))
   Product: gcc
   Version: 13.2.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: dhylands at gmail dot com
  Target Milestone: ---

Created attachment 58091
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58091=edit
File that compiles with no warnings

I'm using the ARM Toolchain
arm-gnu-toolchain-13.2.Rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-g++

running on Ubuntu 20.04

If I delcare my structure using:

struct Foo {
char y;
int x;
} __attribute__((packed));

then the compiler correctly gives me a warning about taking the address of a
packed member:

warning: taking address of packed member of ‘Foo’ may result in an unaligned
pointer value [-Waddress-of-packed-member]

However, if I change the structure to use #pragma pack(push, 1) 

#pragma pack(push, 1)
struct Foo {
char y;
int x;
};
#pragma pack(pop)

then I don't get the warning (and my bug is that it should give the same
warning).

In either case the member offsets and structure size are the same.

on rv32gcv newlib/linux.
So the issue here is the code tried to handle DFmode inputs for rv32 by 
converting to a SImode integer.  That's not a good idea on multiple 
levels.  But if we focus just on math-nearbyint-run-2.


The coefficient test was based on the input mode, DF in this case.  That 
test said, yes it was safe to use the conversion instruction.  The 
conversion instruction was generating an SImode output, so the set of 
values it could correctly handle was limited by the range of an SImode 
object.  The mismatch caused things to go astray.


Pondering this space overnight what's clear to me is that the 
coefficient test and the output of the conversion must be based on the 
same sized objects.  ie, DF/DI or SF/SI.  Doing something like DF/SI 
isn't right.


This means in the rv32 space, we can't use the conversion instructions 
for a DFmode object.  Pretty simple.


While I was in the code the other issue I saw was HFmode handling.  We 
can handle HFmode when Zfa is enabled, but we should avoid it otherwise 
as we don't have the relevant patterns we'd need.


I'm testing a fix for both of these issues as well as the whitespace 
nits caught by the CI system.

Bug ID: 114927
   Summary: ICE when building Emacs with -std=c23 -flto (error:
‘TYPE_CANONICAL’ has different ‘TYPE_CANONICAL’)
   Product: gcc
   Version: 14.0
Status: UNCONFIRMED
  Keywords: ice-checking
  Severity: normal
  Priority: P3
 Component: c

process.i.xz

Hit this when building Emacs with -std=c23 (which bleeding-edge autoconf now
defaults to).

(Calling this an FE issue for now unless proven otherwise, given richi's
comments on my other bug wrt where the checking is done.)

[PATCH] DCE __cxa_atexit calls where the function is pure/const [PR19661]

2024-05-02 Thread Andrew Pinski

In C++ sometimes you have a deconstructor function which is "empty", like for an
example with unions or with arrays.  The front-end might not know it is empty 
either
so this should be done on during optimization.o
To implement it I added it to DCE where we mark if a statement is necessary or 
not.

Bootstrapped and tested on x86_64-linux-gnu with no regressions.

PR tree-optimization/19661

gcc/ChangeLog:

* tree-ssa-dce.cc (is_cxa_atexit): New function.
(is_removable_cxa_atexit_call): New function.
(mark_stmt_if_obviously_necessary): Don't mark removable
cxa_at_exit calls.
(mark_all_reaching_defs_necessary_1): Likewise.
(propagate_necessity): Likewise.

gcc/testsuite/ChangeLog:

* g++.dg/tree-ssa/cxa_atexit-1.C: New test.
* g++.dg/tree-ssa/cxa_atexit-2.C: New test.
* g++.dg/tree-ssa/cxa_atexit-3.C: New test.
* g++.dg/tree-ssa/cxa_atexit-4.C: New test.
* g++.dg/tree-ssa/cxa_atexit-5.C: New test.

[wwwdocs] Add znver5 to GCC 14 changes

2024-05-02 Thread Martin Jambor

Hello,

based on input from AMD, I'd like to commit the following to the wwwdocs
repo to point out new support for Zen 5 based AMD CPUs in GCC 14?

Is it OK?  Any suggestions, comments or questions?

Thanks,

Martin

[Bug tree-optimization/25290] PHI-OPT could be rewritten so that is uses match

There is a secondary part to value_replacement which requires more work than
just working on the phi. I have to think of how to handle that.

Handled.

This is handled.

There is a new part of minmax which I have a patch for but there is one part
missing still (recorded in PR 101024)

> * factor_out_conditional_conversion: will never move, though it needs
> improvement and moved already (PR 56223 and PR 13563)

I have an implementation which moves this over to using gimple_match_op (which
I need to a few testcases for it). Though some of this maybe should move over
to match ...

> * spaceship_replacement: cannot move to match.pd depends on use afterwards
> which is not hard to deal with in a match pattern.

I have to look at what is done for spaceship and maybe merge it in with what is
done for value_replacement (comparison after the phi) since they implement a
similar optimization.

Start of rewriting value_replacement to use match-and-simplify

This is a start and does not remove the old code. It has a few small
regressions due to not being able to merge the bb when doing the replacement.
this is something which I am working on but I am posting it here as I stopping
to work on this for a month or so but will come back to it.

There's no reason for libgo to support a version that GCC itself
doesn't support.  If you send me a patch I can apply it.  Thanks.

+
+The behavior of pragma GCC target and specifically how it affects ISA
+macros has changed in GCC 14.  In GCC 13 and older, the GCC

+C when using the integrated preprocessor during compilation but not

[PATCH 2/3] Improve DECL_EXPR printing in .original [PR23872]

2024-05-02 Thread Andrew Pinski

Right now we don't print that a DECL_EXPR and we get
basically double output of the decls and it looks confusing.
This fixes that.
for the simple example:
`void foo () { int result = 0;}`
This gives:
```
{
  int result = 0;

  DECL_EXPR;
}
```

Bootstrapped and tested on x86_64-linux-gnu with no regressions.

gcc/ChangeLog:

* tree-pretty-print.cc (dump_generic_node ): Print
out `DECL_EXPR<...>` around the decl and update the call to
print_declaration to pass false for new argument and pass 0
for the spacing.
(print_declaration): Add argument is_stmt and don't print
a semicolon nor the initializer.
* tree-pretty-print.h (print_declaration): Add bool argument
and default it to true.

[PATCH 3/3] Add parentheses around DECL_INIT for .original [PR23872]

2024-05-02 Thread Andrew Pinski

When we have :
`void f (int y, int z) { int x = ( z++,y); }`

This would have printed the decl's initializer without
parentheses which can confusion if you think that is defining
another variable rather than the compound expression.

This adds parenthese around DECL_INIT if it was a COMPOUND_EXPR.

Bootstrapped and tested on x86_64-linux-gnu.

[PATCH 1/3] Fix printing COMPOUND_EXPR in .original [PR23872]

2024-05-02 Thread Andrew Pinski

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.
