[PATCH v1] RISC-V: Add test for FP llceil auto vectorization

[pan2 . li]

From: Pan Li 

The below FP API are supported already by sharing the same standard
name, as well as the machine mode.

long long llceil (double);

This patch would like to add the test cases for ensuring the
correctness.

PATCH-1v3, expand] Enable vector mode for compare_by_pieces [PR111449]

[HAO CHEN GUI]

Hi,
  Vector mode instructions are efficient for compare on some targets.
This patch enables vector mode for compare_by_pieces. Currently,
vector mode is enabled for compare, set and clear. Helper function
"qi_vector_p" decides if vector mode is enabled for certain by pieces
operation. optabs_checking checks if optabs are available for the
mode and certain by pieces operations. Both of them are called in
fixed_size_mode finding functions. A member is added to class
op_by_pieces_d in order to record the type of by pieces operations.

  The test case is in the second patch which is rs6000 specific.

  Compared to last version, the main change is to create two helper
functions and call them in mode finding function.

  Bootstrapped and tested on x86 and powerpc64-linux BE and LE with no
regressions.

Thanks
Gui Haochen

[PATCH] Add support for SLP vectorization of OpenMP SIMD clone calls

[Richard Biener]

This adds support for SLP vectorization of OpenMP SIMD clone calls.
There's a complication when vectorizing calls involving virtual
operands since this is now for the first time not only leafs (loads
or stores).  With SLP this runs into the issue that placement of
the vectorized stmts is not necessarily at one of the original
scalar stmts which leads to the magic updating virtual operands
in vect_finish_stmt_generation not working.  So we run into the
assert that updating virtual operands isn't necessary.  I've
papered over this similar to how we do for mismatched const/pure
attribution by setting vinfo->any_known_not_updated_vssa.

I've added two basic testcases with multi-lane SLP and verified
that with single-lane SLP enabled the rest of the existing testcases
pass.

Bootstrapped and tested on x86_64-unknown-linux-gnu, will push later 
today.

Richard.

* tree-vect-slp.cc (mask_call_maps): New.
(vect_get_operand_map): Handle IFN_MASK_CALL.
(vect_build_slp_tree_1): Likewise.
* tree-vect-stmts.cc (vectorizable_simd_clone_call): Handle
SLP.

* gcc.dg/vect/slp-simd-clone-1.c: New testcase.
* gcc.dg/vect/slp-simd-clone-2.c: Likewise.

'leaf' is really a modifier for the other branch protection strategies; perhaps 
it would be better to describe it as that.

But this brings up another issue/question.  If the compiler has been configured 
with, say, '--enable-branch-protection=standard' or some other variety, is 
there (or do we want) a way to extend that to leaf functions without changing 
the underlying strategy?

Or maybe better still: "branch protection strategies 'none' and 'pac-ret' are 
incompatible".

But this is all a matter of taste.

However, this patch should be merged with the patch that changes the error

Probably already preexisting, by I wonder how safe remove_attribute is.
Aren't attributes shared in some cases
(like __attribute__((attr1, attr2, attr3)) int a, b, c, d;)?
Not really sure if something unshares them afterwards.
If they are shared, adding new attributes is fine, that will make the new
additions not shared and the tail shared, but remove_attribute could remove
it from all of them at once.  Perhaps I'm wrong, haven't verified.

Otherwise LGTM (though, I didn't spot anything about allocatables in the
patch, am I just looking wrong or are they still unsupported)?

[PATCH v1] RISC-V: Refine run test cases of math autovec

[pan2 . li]

From: Pan Li 

For the run test cases of math autovec, we need a reference value to
check if the return value is expected or not.

The previous patch leverage hardcode for the reference value but we
can leverage the scalar math function instead. For example ceil after
autovec.

ASSERT (CEIL (Vector {1.2,...}) == Vector {2.0, ...});

But we can leverage the scalar math function to avoid potential mistakes.

ASSERT (CEIL (Vector {1.2,...}) == Vector {ceil (1.2), ...});

This patch remove some fflags check as it covered by check-body already.

gcc/testsuite/ChangeLog:

* gcc.target/riscv/rvv/autovec/unop/math-ceil-run-1.c:
Use scalar func as reference instead of hardcode.

Adding RVV when SVE or GCN is already there looks obvious to me, these
kind of changes are pre-approved.  No need for all the noise.

[PATCH] OMP SIMD inbranch call vectorization for AVX512 style masks

[Richard Biener]

The following teaches vectorizable_simd_clone_call to handle
integer mode masks.  The tricky bit is to second-guess the
number of lanes represented by a single mask argument - the following
uses simdlen and the number of mask arguments to calculate that,
assuming ABIs have them uniform.

Similar to the VOIDmode handling there's a restriction on not
supporting splitting/merging of incoming vector masks to
more/less SIMD call arguments.

Bootstrapped and tested on x86_64-unknown-linux-gnu, re-testing
after a minor change.  Will push later.

Richard.

Technically PR 111622 exposes a bug in GCC 13, but its been papered over 
on trunk by this:

tree-optimization/111294 - better DCE after forwprop


This removes a lot of dead statements, but those statements were being 
added to the list of partial equivalences and causing some serious 
compile time issues.


Rangers cache loops through equivalences when its propagating on-entry 
values, so if the partial equivalence list is very large, it can consume 
a lot of time.  Typically, partial equivalence lists are small.   In 
this case, a lot of dead stmts were not removed, so there was no 
redundancy elimination and it was causing an issue.   This patch 
actually speeds things up a hair in the normal case too.


Bootstrapped on x86_64-pc-linux-gnu with no regressions.  pushed.

Probably already preexisting, by I wonder how safe remove_attribute is.
Aren't attributes shared in some cases
(like __attribute__((attr1, attr2, attr3)) int a, b, c, d;)?


I think there should be no problem – new attributes get added as:

DECL_ATTRIBUTES (var) = tree_cons (get_identifier ("omp allocate"),
   t, DECL_ATTRIBUTES (var));

Thus, attr = DECL_ATTRIBUTES (var) is not shared, even if
TREE_CHAIN (attr) might be shared.

Thus, as long as new attributes get added at the head of the chain,
there should be no issue. And "omp allocate" is added once per decl
and is therefore not shared - removing might create again a shared
tree, but any following 'tree_cons' will again unshare it.

I think in your case, there would be indeed a problem when doing:
  'tree attr = remove_attr (...("attr2") ...)'
as this would remove "attr2" for 4 decls.

* * *

However, as 'omp allocate' is not used later on, I also do not need
to remove it.

=> Updated patch attached + interdiff for gimplify.cc attached.

Changes:
* Condition now the same as previously
* Keep 'omp allocate' also for DECL_VALUE_EXPR variable
* Add assert that we either have Fortran's expression the GOMP_FREE
  location - or a DECL_VALUE_EXPR.
* Make use of the assertion by keeping the HAS_DECL_VALUE expr below;
  this avoids adding an align/allocator == default check.
  => same code as old code, except for creating + using 'v' variable
  and adding a clobber.

* * *


Otherwise LGTM (though, I didn't spot anything about allocatables in the
patch, am I just looking wrong or are they still unsupported)?


It's unsupported – albeit Chung-Lin has some patch for it. The code path
is completely different. It already starts by 'omp allocators' (+
legacy: 'omp allocate') being not declarative but executable and
associated with a Fortran 'allocate'  statement and ...

Sorry for being slow - but I keep getting distracted by other tasks ...

Follow-up on the pch tests.  The errors are an artifact of my testing.
I usually build unpatched without bootstrap and patched with it, comparing
the testsuite results.

When bootstrapping unpatched, the same errors occur.  When bootstrapping
with --with-arch=native we essentially use a vpxor for a memset which is
an illegal instruction on gc188 of the compile farm.  This might be a
known bug but I haven't found something in bugzilla.

In total:  Bootstrap and testsuite unchanged on x86, aarch64 and power10.

I think this would involve rewriting the argument handling for all gen*
tools (it is shared via gensupport).  Currently, I make use of the
callback and just add two new options which helps limit the number of
changes.  Is stdout so valuable from a debugging point of view that
changing it would be prohibitive?  Of course it's a change but I usually
grep through insn-emit.cc anyways and that would still be possible.

Debugging here refers to debugging the output of gen*, which usually one does
With small examples when modifying the tool itself.

Hmm why? The same callback you use to consume the listed arguments can be used 
to
consume the list can it not? I may be wrong, but from what I remember the 
callback
is called when main can't consume an argv value and it's allowed to eat all 
remaining input?

But I'll leave it up to Richard. Having to read multiple files to check a 
change to gen*
seems like a usability issue though.

I went through some of our test cases and believe most of the problems
are due to situations like the following:

In vect-cond-arith-2.c we have (on riscv)
  vect_neg_xi_14.4_23 = -vect_xi_13.3_22;
  vect_res_2.5_24 = .COND_LEN_ADD ({ -1, ... }, vect_res_1.0_17, 
vect_neg_xi_14.4_23, vect_res_1.0_17, _29, 0);

On aarch64 this is a situation that matches the VEC_COND_EXPR
simplification that I disabled with this patch.  We valueized
to _26 = vect_res_1.0_17 - vect_xi_13.3_22 and then create
vect_res_2.5_24 = VEC_COND_EXPR ;
This is later re-assembled into a COND_SUB.

As we have two masks or COND_LEN we cannot use a VEC_COND_EXPR to
achieve the same thing.  Would it be possible to create a COND_OP
directly instead, though?  I tried the following (not very polished
obviously):

-  new_op.set_op (VEC_COND_EXPR, res_op->type,
-res_op->cond.cond, res_op->ops[0],
-res_op->cond.else_value);
-  *res_op = new_op;
-  return gimple_resimplify3 (seq, res_op, valueize);
+  if (!res_op->cond.len)
+   {
+ new_op.set_op (VEC_COND_EXPR, res_op->type,
+res_op->cond.cond, res_op->ops[0],
+res_op->cond.else_value);
+ *res_op = new_op;
+ return gimple_resimplify3 (seq, res_op, valueize);
+   }
+  else if (seq && *seq && is_gimple_assign (*seq))
+   {
+ new_op.code = gimple_assign_rhs_code (*seq);
+ new_op.type = res_op->type;
+ new_op.num_ops = gimple_num_ops (*seq) - 1;
+ new_op.ops[0] = gimple_assign_rhs1 (*seq);
+ if (new_op.num_ops > 1)
+   new_op.ops[1] = gimple_assign_rhs2 (*seq);
+ if (new_op.num_ops > 2)
+   new_op.ops[2] = gimple_assign_rhs2 (*seq);
+
+ new_op.cond = res_op->cond;
+
+ gimple_match_op bla2;
+ if (convert_conditional_op (&new_op, &bla2))
+   {
+ *res_op = bla2;
+ // SEQ should now be dead.
+ return true;
+   }
+   }

This would make the other hunk (check whether it was a LEN
and try to recreate it) redundant I hope.

I don't know enough about valueization, whether it's always
safe to do that and other implications.  On riscv this seems
to work, though and the other backends never go through the LEN
path.  If, however, this is a feasible direction it could also
be done for the non-LEN targets?

 Robin

You are right.  The line above works as expected, but

  1 ? 1 : ((1 ? 1 : id (42)), id (i));

shows the problem (when the expression isn't used as an initializer).

Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk?

-- >8 --
My recent patch introducing cp_fold_immediate_r caused exponential
compile time with nested COND_EXPRs.  The problem is that the COND_EXPR
case recursively walks the arms of a COND_EXPR, but after processing
both arms it doesn't end the walk; it proceeds to walk the
sub-expressions of the outermost COND_EXPR, triggering again walking
the arms of the nested COND_EXPR, and so on.  This patch brings the
compile time down to about 0m0.033s.

The ff_fold_immediate flag is unused after this patch but since I'm
using it in the P2564 patch, I'm not removing it now.

Continued (Non)mutlib and stub header issue (was Re: [PATCH v2] RISC-V: Use stdint-gcc.h in rvv testsuite)

[Vineet Gupta]

Hi Kito, Christoph, Patrick,

I've been trying to test a specific non multilib config 
(rv64-zicond_zfa) and seeing noisy output (compared to a similar multlib 
build) and it seems there's still a bunch of this header issue (for the 
rv32 abi headers) in the non-multlib config.


e.g.
FAIL: gcc.dg/vect/costmodel/riscv/rvv/dynamic-lmul1-7.c -O3 
-ftree-vectorize --param riscv-autovec-lmul=dynamic (test for excess errors)

...
...

The errors are missing header :

 from 
gcc/gcc/testsuite/gcc.dg/vect/costmodel/riscv/rvv/dynamic-lmul1-7.c:4:
INSTALL/tc-up-231010-zicond-zfa-non-multilib/sysroot/usr/include/gnu/stubs.h:8:11: 
fatal error: gnu/stubs-ilp32.h: No such file or directory



When looking around, I stumbled upon commit
    d0bbecb1c41 "RISC-V: Add riscv_vector.h wrapper in testsuite to 
prevent pull in stdint.h from C library"


Which seems like a step in a right direction, but how does one ensure 
that the wrapper riscv_vector.h (containing stdint-gcc.h) is included by 
test vs. the default riscv_vector.h (which is more user facing and thus 
needs to include the system stdint.h)


P.S. I couldn't find the posting for above commit on gcc-patches ?

Thx,
-Vineet

[PATCH v18 00/40] Optimize type traits performance

[Ken Matsui]

This patch series optimizes type traits performance by implementing
built-in type traits and using them in libstdc++.

Changes in v18:

* Removed all RID values for built-in traits and used cik_trait
instead.
* Improved to handle the use of non-function-like built-in trait
identifiers.
* Reverted all changes to conflicted identifiers with new built-ins
in the existing code base.

Changes in v17:

* Rebased on top of trunk.

[PATCH v18 02/40] c-family, c++: Look up built-in traits through gperf

[Ken Matsui]

Since RID_MAX soon reaches 255 and all built-in traits are used approximately
once in a C++ translation unit, this patch removes all RID values for built-in
traits and uses gperf to look up the specific trait. Rather than holding
traits as keywords, we set all trait identifiers as cik_trait, which is a new
cp_identifier_kind. As cik_reserved_for_udlit was unused and
cp_identifier_kind is 3 bits, we replaced the unused field with the new
cik_trait. Also, the later patch handles a subsequent token to the built-in
identifier so that we accept the use of non-function-like built-in trait
identifiers.

gcc/c-family/ChangeLog:

* c-common.cc (c_common_reswords): Remove all mappings of
built-in traits.
* c-common.h (enum rid): Remove all RID values for built-in traits.

gcc/cp/ChangeLog:

* Make-lang.in: Add targets to generate cp-trait.gperf and
cp-trait.h.
* cp-objcp-common.cc (names_builtin_p): Remove all RID value
cases for built-in traits.  Check for built-in traits via
the new cik_trait identifier.
* cp-tree.h (cik_reserved_for_udlit): Rename to ...
(cik_trait): ... this.
(IDENTIFIER_ANY_OP_P): Exclude cik_trait.
(IDENTIFIER_TRAIT_P): New macro to detect cik_trait.
* lex.cc (init_cp_traits): New function to set cik_trait for all
built-in trait identifiers.
(cxx_init): Call init_cp_traits function.
* parser.cc (cp_lexer_lookup_trait): New function to look up a
built-in trait from a token by gperf.
(cp_lexer_lookup_trait_expr): Likewise, look up an
expression-yielding built-in trait.
(cp_lexer_lookup_trait_type): Likewise, look up a type-yielding
built-in trait.
(cp_keyword_starts_decl_specifier_p): Remove all RID value cases
for built-in traits.
(cp_lexer_next_token_is_decl_specifier_keyword): Handle
type-yielding built-in traits.
(cp_parser_primary_expression): Remove all RID value cases for
built-in traits.  Handle expression-yielding built-in traits.
(cp_parser_trait): Handle cp_trait instead of enum rid.
(cp_parser_simple_type_specifier): Remove all RID value cases
for built-in traits.  Handle type-yielding built-in traits.
* cp-trait-head.in: New file.
* cp-trait.gperf: New file.
* cp-trait.h: New file.

[PATCH v18 03/40] c++: Accept the use of non-function-like built-in trait identifiers

[Ken Matsui]

This patch accepts the use of non-function-like built-in trait
identifiers.  Specifically, we check if the subsequent token is '(' for
ordinary built-in traits or is '<' only for the special __type_pack_element
built-in trait.  If the same identifiers are used in other cases, the
parser treats them as normal identifiers.  This allows us to accept code
like:

struct __is_pointer {};

gcc/cp/ChangeLog:

* parser.cc (cp_lexer_lookup_trait): Rename to ...
(cp_lexer_peek_trait): ... this.  Handle a subsequent token for
the corresponding built-in trait.
(cp_lexer_lookup_trait_expr): Rename to ...
(cp_lexer_peek_trait_expr): ... this.
(cp_lexer_lookup_trait_type): Rename to ...
(cp_lexer_peek_trait_type): ... this.
(cp_lexer_next_token_is_decl_specifier_keyword): Call
cp_lexer_peek_trait_type.
(cp_parser_simple_type_specifier): Likewise.
(cp_parser_primary_expression): Call cp_lexer_peek_trait_expr.

This patch implements built-in trait for std::is_const.

gcc/cp/ChangeLog:

* Make-lang.in: Update key positions for gperf, based on
automatically computed values.
* cp-trait.def: Define __is_const.
* cp-trait.gperf: Reflect cp-trait.def change.
* cp-trait.h: Likewise.
* constraint.cc (diagnose_trait_expr): Handle CPTK_IS_CONST.
* semantics.cc (trait_expr_value): Likewise.
(finish_trait_expr): Likewise.

gcc/testsuite/ChangeLog:

* g++.dg/ext/has-builtin-1.C: Test existence of __is_const.
* g++.dg/ext/is_const.C: New test.

IIRC it rely on #include "" vs #include <>, the former will
search the same folder first, then the header search path,
so...made a dummy one, and put into test folder, then it will use our
own version now :P

but I guess maybe the right way (or simpler way) is just adding an
extra header search path to CFLAG and making a dummy stdint.h as well?

[PATCH] c++: fix truncated diagnostic in C++23 [PR111272]

[Marek Polacek]

Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk?

-- >8 --
In C++23, since P2448, a constexpr function F that calls a non-constexpr
function N is OK as long as we don't actually call F in a constexpr
context.  So instead of giving an error in maybe_save_constexpr_fundef,
we only give an error when evaluating the call.  Unfortunately, as shown
in this PR, the diagnostic can be truncated:

z.C:10:13: note: 'constexpr Jam::Jam()' is not usable as a 'constexpr' function 
because:
   10 |   constexpr Jam() { ft(); }
  | ^~~

...because what?  With this patch, we say:

z.C:10:13: note: 'constexpr Jam::Jam()' is not usable as a 'constexpr' function 
because:
   10 |   constexpr Jam() { ft(); }
  | ^~~
z.C:10:23: error: call to non-'constexpr' function 'int Jam::ft()'
   10 |   constexpr Jam() { ft(); }
  | ~~^~
z.C:8:7: note: 'int Jam::ft()' declared here
8 |   int ft() { return 42; }
  |   ^~

Like maybe_save_constexpr_fundef, explain_invalid_constexpr_fn should
also check the body of a constructor, not just the mem-initializer.

PR c++/111272

gcc/cp/ChangeLog:

* constexpr.cc (explain_invalid_constexpr_fn): Also check the body of
a constructor in C++14 and up.

gcc/testsuite/ChangeLog:

* g++.dg/cpp1y/constexpr-diag1.C: New test.

[PATCH v19 00/40] Optimize type traits performance

[Ken Matsui]

This patch series optimizes type traits performance by implementing
built-in type traits and using them in libstdc++.

Changes in v19:

* Fixed a typo.
* Rebased on top of trunk.
* Improved clarity of the commit message.

Changes in v18:

* Removed all RID values for built-in traits and used cik_trait
instead.
* Improved to handle the use of non-function-like built-in trait
identifiers.
* Reverted all changes to conflicted identifiers with new built-ins
in the existing code base.

Changes in v17:

* Rebased on top of trunk.
* Improved clarity of the commit message.
* Simplified Make-lang.in.
* Made ridpointers for RID_TRAIT_EXPR and RID_TRAIT_TYPE empty.

Changes in v16:

* Rebased on top of trunk.
* Improved clarity of the commit message.
* Simplified Make-lang.in and gperf struct.
* Supply -k option to gperf to support older versions than 2.8.

Changes in v15:

[PATCH v19 02/40] c-family, c++: Look up built-in traits through gperf

[Ken Matsui]

Since RID_MAX soon reaches 255 and all built-in traits are used approximately
once in a C++ translation unit, this patch removes all RID values for built-in
traits and uses gperf to look up the specific trait.  Rather than holding
traits as keywords, we set all trait identifiers as cik_trait, which is a new
cp_identifier_kind.  As cik_reserved_for_udlit was unused and
cp_identifier_kind is 3 bits, we replaced the unused field with the new
cik_trait.  Also, the later patch handles a subsequent token to the built-in
identifier so that we accept the use of non-function-like built-in trait
identifiers.

gcc/c-family/ChangeLog:

* c-common.cc (c_common_reswords): Remove all mappings of
built-in traits.
* c-common.h (enum rid): Remove all RID values for built-in traits.

gcc/cp/ChangeLog:

* Make-lang.in: Add targets to generate cp-trait.gperf and
cp-trait.h.
* cp-objcp-common.cc (names_builtin_p): Remove all RID value
cases for built-in traits.  Check for built-in traits via
the new cik_trait identifier.
* cp-tree.h (cik_reserved_for_udlit): Rename to ...
(cik_trait): ... this.
(IDENTIFIER_ANY_OP_P): Exclude cik_trait.
(IDENTIFIER_TRAIT_P): New macro to detect cik_trait.
* lex.cc (init_cp_traits): New function to set cik_trait for all
built-in trait identifiers.
(cxx_init): Call init_cp_traits function.
* parser.cc (cp_lexer_lookup_trait): New function to look up a
built-in trait from a token by gperf.
(cp_lexer_lookup_trait_expr): Likewise, look up an
expression-yielding built-in trait.
(cp_lexer_lookup_trait_type): Likewise, look up a type-yielding
built-in trait.
(cp_keyword_starts_decl_specifier_p): Remove all RID value cases
for built-in traits.
(cp_lexer_next_token_is_decl_specifier_keyword): Handle
type-yielding built-in traits.
(cp_parser_primary_expression): Remove all RID value cases for
built-in traits.  Handle expression-yielding built-in traits.
(cp_parser_trait): Handle cp_trait instead of enum rid.
(cp_parser_simple_type_specifier): Remove all RID value cases
for built-in traits.  Handle type-yielding built-in traits.
* cp-trait-head.in: New file.
* cp-trait.gperf: New file.
* cp-trait.h: New file.

[PATCH v19 03/40] c++: Accept the use of built-in trait identifiers

[Ken Matsui]

This patch accepts the use of built-in trait identifiers when they are
actually not used as traits.  Specifically, we check if the subsequent token
is '(' for ordinary built-in traits or is '<' only for the special
__type_pack_element built-in trait.  If those identifiers are used
differently, the parser treats them as normal identifiers.  This allows
us to accept code like: struct __is_pointer {};.

gcc/cp/ChangeLog:

* parser.cc (cp_lexer_lookup_trait): Rename to ...
(cp_lexer_peek_trait): ... this.  Handle a subsequent token for
the corresponding built-in trait.
(cp_lexer_lookup_trait_expr): Rename to ...
(cp_lexer_peek_trait_expr): ... this.
(cp_lexer_lookup_trait_type): Rename to ...

[PATCH v19 26/40] libstdc++: Optimize is_object trait performance

[Ken Matsui]

This patch optimizes the performance of the is_object trait by dispatching to
the new __is_function and __is_reference built-in traits.

libstdc++-v3/ChangeLog:
* include/std/type_traits (is_object): Use __is_function and
__is_reference built-in traits.
(is_object_v): Likewise.
