cross/gcc-*: upgrade to 14.3.0-r1

Browse source 
Done with pmb MR 2521. I've verified that gcc-aarch64 builds and the
following packages can be cross compiled from aarch64 to x86_64:

* hello-world
* iskey
* pbsplash
* gcc-x86_64

From 4d0a333ef13e2da140cd44c4941b20f48a80dc0f Mon Sep 17 00:00:00 2001
From: Hannes Braun <hannes@hannesbraun.net>
Date: Thu, 20 Feb 2025 15:09:41 +0100
Subject: [PATCH] arm: Fix signedness of vld1q intrinsic parms [PR118942]
vld1q_s8_x3, vld1q_s16_x3, vld1q_s8_x4 and vld1q_s16_x4 were expecting
pointers to unsigned integers. These parameters should be pointers to
signed integers.
gcc/ChangeLog:
PR target/118942
* config/arm/arm_neon.h (vld1q_s8_x3): Use int8_t instead of
uint16_t.
(vld1q_s16_x3): Use int16_t instead of uint16_t.
(vld1q_s8_x4): Likewise.
(vld1q_s16_x4): Likewise.
gcc/testsuite/ChangeLog:
PR target/118942
* gcc.target/arm/simd/vld1q_base_xN_1.c: Add -Wpointer-sign.

Subject: [PATCH 1/4] aarch64: Fix invalid nested subregs [PR115464]
The testcase extracts one arm_neon.h vector from a pair (one subreg)
and then reinterprets the result as an SVE vector (another subreg).
Each subreg makes sense individually, but we can't fold them together
into a single subreg: it's 32 bytes -> 16 bytes -> 16*N bytes,
but the interpretation of 32 bytes -> 16*N bytes depends on
whether N==1 or N>1.
Since the second subreg makes sense individually, simplify_subreg
should bail out rather than ICE on it. simplify_gen_subreg will
then do the same (because it already checks validate_subreg).
This leaves simplify_gen_subreg returning null, requiring the
caller to take appropriate action.
I think this is relatively likely to occur elsewhere, so the patch
adds a helper for forcing a subreg, allowing a temporary pseudo to
be created where necessary.
I'll follow up by using force_subreg in more places. This patch
is intended to be a minimal backportable fix for the PR.

This patch makes the aarch64 code use force_subreg instead of

(1) The code is obviously specific to expand (where new pseudos
can be created).
(2) The value is obviously an rvalue rather than an lvalue.
(3) The offset wasn't a simple lowpart or highpart calculation;
a later patch will deal with those.

Subject: [PATCH 4/4] Add force_lowpart_subreg
optabs had a local function called lowpart_subreg_maybe_copy
that is very similar to the lowpart version of force_subreg.
This patch adds a force_lowpart_subreg wrapper around
force_subreg and uses it in optabs.cc.
The only difference between the old and new functions is that
the old one asserted success while the new one doesn't.
It's common not to assert elsewhere when taking subregs;
normally a null result is enough.
Later patches will make more use of the new function.
gcc/
* explow.h (force_lowpart_subreg): Declare.
* explow.cc (force_lowpart_subreg): New function.
* optabs.cc (lowpart_subreg_maybe_copy): Delete.
(expand_absneg_bit): Use force_lowpart_subreg instead of
lowpart_subreg_maybe_copy.
(expand_copysign_bit): Likewise.

Subject: [PATCH] libquadmath: Fix up libquadmath/math/sqrtq.c compilation in
some powerpc* configurations [PR116007]
My PR114623 change started using soft-fp.h and quad.h for the sqrtq implementation.
Unfortunately, that seems to fail building in some powerpc* configurations, where
TFmode isn't available.
quad.h has:
#ifndef TFtype
typedef float TFtype __attribute__ ((mode (TF)));
#endif
and uses TFtype. quad.h has:
/* Define the complex type corresponding to __float128
("_Complex __float128" is not allowed) */
#if (!defined(_ARCH_PPC)) || defined(__LONG_DOUBLE_IEEE128__)
typedef _Complex float __attribute__((mode(TC))) __complex128;
#else
typedef _Complex float __attribute__((mode(KC))) __complex128;
#endif
with the conditional and KCmode use added during porting of libquadmath
to powerpc*, so I've just defined TFtype for powerpc when __LONG_DOUBLE_IEEE128__
isn't defined; I could define it to float __attribute__ ((mode (KF))) but it
seemed easier to just define it to __float128 which should do the same thing.
2024-08-03 Jakub Jelinek <jakub@redhat.com>
PR target/116007
* math/sqrtq.c (TFtype): For PowerPC without __LONG_DOUBLE_IEEE128__
define to __float128 before including soft-fp.h and quad.h.

Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
Currently the forward threader isn't limited as to the search space
it explores and with it now using path-ranger for simplifying
conditions it runs into it became pretty slow for degenerate cases
like compiling insn-emit.cc for RISC-V esp. when compiling for
a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
The following makes the forward threader honor the search space
limit I introduced for the backward threader. This reduces
compile-time from minutes to seconds for the testcase in PR116166.
Note this wasn't necessary before we had ranger but with ranger
the work we do is quadatic in the length of the threading path
we build up (the same is true for the backwards threader).
PR tree-optimization/116166
* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
Add limit parameter.
(jump_threader::thread_through_normal_block): Likewise.
* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
Honor and decrement limit parameter.
(jump_threader::thread_through_normal_block): Likewise.
(jump_threader::thread_across_edge): Initialize limit from
param_max_jump_thread_paths and pass it down to workers.

From 4d0a333ef13e2da140cd44c4941b20f48a80dc0f Mon Sep 17 00:00:00 2001
From: Hannes Braun <hannes@hannesbraun.net>
Date: Thu, 20 Feb 2025 15:09:41 +0100
Subject: [PATCH] arm: Fix signedness of vld1q intrinsic parms [PR118942]
vld1q_s8_x3, vld1q_s16_x3, vld1q_s8_x4 and vld1q_s16_x4 were expecting
pointers to unsigned integers. These parameters should be pointers to
signed integers.
gcc/ChangeLog:
PR target/118942
* config/arm/arm_neon.h (vld1q_s8_x3): Use int8_t instead of
uint16_t.
(vld1q_s16_x3): Use int16_t instead of uint16_t.
(vld1q_s8_x4): Likewise.
(vld1q_s16_x4): Likewise.
gcc/testsuite/ChangeLog:
PR target/118942
* gcc.target/arm/simd/vld1q_base_xN_1.c: Add -Wpointer-sign.

Subject: [PATCH 1/4] aarch64: Fix invalid nested subregs [PR115464]
The testcase extracts one arm_neon.h vector from a pair (one subreg)
and then reinterprets the result as an SVE vector (another subreg).
Each subreg makes sense individually, but we can't fold them together
into a single subreg: it's 32 bytes -> 16 bytes -> 16*N bytes,
but the interpretation of 32 bytes -> 16*N bytes depends on
whether N==1 or N>1.
Since the second subreg makes sense individually, simplify_subreg
should bail out rather than ICE on it. simplify_gen_subreg will
then do the same (because it already checks validate_subreg).
This leaves simplify_gen_subreg returning null, requiring the
caller to take appropriate action.
I think this is relatively likely to occur elsewhere, so the patch
adds a helper for forcing a subreg, allowing a temporary pseudo to
be created where necessary.
I'll follow up by using force_subreg in more places. This patch
is intended to be a minimal backportable fix for the PR.

Subject: [PATCH 2/4] aarch64: Use force_subreg in more places
This patch makes the aarch64 code use force_subreg instead of
simplify_gen_subreg in more places. The criteria were:
(1) The code is obviously specific to expand (where new pseudos
can be created).
(2) The value is obviously an rvalue rather than an lvalue.
(3) The offset wasn't a simple lowpart or highpart calculation;
a later patch will deal with those.

Subject: [PATCH 4/4] Add force_lowpart_subreg
optabs had a local function called lowpart_subreg_maybe_copy
that is very similar to the lowpart version of force_subreg.
This patch adds a force_lowpart_subreg wrapper around
force_subreg and uses it in optabs.cc.
The only difference between the old and new functions is that
the old one asserted success while the new one doesn't.
It's common not to assert elsewhere when taking subregs;
normally a null result is enough.
Later patches will make more use of the new function.
gcc/
* explow.h (force_lowpart_subreg): Declare.
* explow.cc (force_lowpart_subreg): New function.
* optabs.cc (lowpart_subreg_maybe_copy): Delete.
(expand_absneg_bit): Use force_lowpart_subreg instead of
lowpart_subreg_maybe_copy.
(expand_copysign_bit): Likewise.
(cherry picked from commit 5f40d1c0cc6ce91ef28d326b8707b3f05e6f239c)

Subject: [PATCH] libquadmath: Fix up libquadmath/math/sqrtq.c compilation in
some powerpc* configurations [PR116007]
My PR114623 change started using soft-fp.h and quad.h for the sqrtq implementation.
Unfortunately, that seems to fail building in some powerpc* configurations, where
TFmode isn't available.
quad.h has:
#ifndef TFtype
typedef float TFtype __attribute__ ((mode (TF)));
#endif
and uses TFtype. quad.h has:
/* Define the complex type corresponding to __float128
("_Complex __float128" is not allowed) */
#if (!defined(_ARCH_PPC)) || defined(__LONG_DOUBLE_IEEE128__)
typedef _Complex float __attribute__((mode(TC))) __complex128;
#else
typedef _Complex float __attribute__((mode(KC))) __complex128;
#endif
with the conditional and KCmode use added during porting of libquadmath
to powerpc*, so I've just defined TFtype for powerpc when __LONG_DOUBLE_IEEE128__
isn't defined; I could define it to float __attribute__ ((mode (KF))) but it
seemed easier to just define it to __float128 which should do the same thing.
2024-08-03 Jakub Jelinek <jakub@redhat.com>
PR target/116007
* math/sqrtq.c (TFtype): For PowerPC without __LONG_DOUBLE_IEEE128__
define to __float128 before including soft-fp.h and quad.h.

Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
Currently the forward threader isn't limited as to the search space
it explores and with it now using path-ranger for simplifying
conditions it runs into it became pretty slow for degenerate cases
like compiling insn-emit.cc for RISC-V esp. when compiling for
a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
The following makes the forward threader honor the search space
limit I introduced for the backward threader. This reduces
compile-time from minutes to seconds for the testcase in PR116166.
Note this wasn't necessary before we had ranger but with ranger
the work we do is quadatic in the length of the threading path
we build up (the same is true for the backwards threader).
PR tree-optimization/116166

Add limit parameter.

From 4d0a333ef13e2da140cd44c4941b20f48a80dc0f Mon Sep 17 00:00:00 2001
From: Hannes Braun <hannes@hannesbraun.net>
Date: Thu, 20 Feb 2025 15:09:41 +0100
Subject: [PATCH] arm: Fix signedness of vld1q intrinsic parms [PR118942]
vld1q_s8_x3, vld1q_s16_x3, vld1q_s8_x4 and vld1q_s16_x4 were expecting
pointers to unsigned integers. These parameters should be pointers to
signed integers.
gcc/ChangeLog:
PR target/118942
* config/arm/arm_neon.h (vld1q_s8_x3): Use int8_t instead of
uint16_t.
(vld1q_s16_x3): Use int16_t instead of uint16_t.
(vld1q_s8_x4): Likewise.
(vld1q_s16_x4): Likewise.
gcc/testsuite/ChangeLog:
PR target/118942
* gcc.target/arm/simd/vld1q_base_xN_1.c: Add -Wpointer-sign.

Subject: [PATCH 1/4] aarch64: Fix invalid nested subregs [PR115464]
The testcase extracts one arm_neon.h vector from a pair (one subreg)
and then reinterprets the result as an SVE vector (another subreg).
Each subreg makes sense individually, but we can't fold them together
into a single subreg: it's 32 bytes -> 16 bytes -> 16*N bytes,
but the interpretation of 32 bytes -> 16*N bytes depends on
whether N==1 or N>1.
Since the second subreg makes sense individually, simplify_subreg
should bail out rather than ICE on it. simplify_gen_subreg will
then do the same (because it already checks validate_subreg).
This leaves simplify_gen_subreg returning null, requiring the
caller to take appropriate action.
I think this is relatively likely to occur elsewhere, so the patch
adds a helper for forcing a subreg, allowing a temporary pseudo to
be created where necessary.
I'll follow up by using force_subreg in more places. This patch
is intended to be a minimal backportable fix for the PR.

Subject: [PATCH 2/4] aarch64: Use force_subreg in more places
This patch makes the aarch64 code use force_subreg instead of
simplify_gen_subreg in more places. The criteria were:
(1) The code is obviously specific to expand (where new pseudos
can be created).
(2) The value is obviously an rvalue rather than an lvalue.
(3) The offset wasn't a simple lowpart or highpart calculation;
a later patch will deal with those.

Subject: [PATCH 4/4] Add force_lowpart_subreg
optabs had a local function called lowpart_subreg_maybe_copy
that is very similar to the lowpart version of force_subreg.
This patch adds a force_lowpart_subreg wrapper around
force_subreg and uses it in optabs.cc.
The only difference between the old and new functions is that
the old one asserted success while the new one doesn't.
It's common not to assert elsewhere when taking subregs;
normally a null result is enough.
Later patches will make more use of the new function.
gcc/
* explow.h (force_lowpart_subreg): Declare.
* explow.cc (force_lowpart_subreg): New function.
* optabs.cc (lowpart_subreg_maybe_copy): Delete.
(expand_absneg_bit): Use force_lowpart_subreg instead of
lowpart_subreg_maybe_copy.
(expand_copysign_bit): Likewise.

Subject: [PATCH] libquadmath: Fix up libquadmath/math/sqrtq.c compilation in
some powerpc* configurations [PR116007]
My PR114623 change started using soft-fp.h and quad.h for the sqrtq implementation.
Unfortunately, that seems to fail building in some powerpc* configurations, where
TFmode isn't available.
quad.h has:
#ifndef TFtype
typedef float TFtype __attribute__ ((mode (TF)));
#endif
and uses TFtype. quad.h has:
/* Define the complex type corresponding to __float128
("_Complex __float128" is not allowed) */
#if (!defined(_ARCH_PPC)) || defined(__LONG_DOUBLE_IEEE128__)
typedef _Complex float __attribute__((mode(TC))) __complex128;
#else
typedef _Complex float __attribute__((mode(KC))) __complex128;
#endif
with the conditional and KCmode use added during porting of libquadmath
to powerpc*, so I've just defined TFtype for powerpc when __LONG_DOUBLE_IEEE128__
isn't defined; I could define it to float __attribute__ ((mode (KF))) but it
seemed easier to just define it to __float128 which should do the same thing.

* math/sqrtq.c (TFtype): For PowerPC without __LONG_DOUBLE_IEEE128__
define to __float128 before including soft-fp.h and quad.h.

From 2cf89ae83225f932b226cd57ef2d083a59bcf8a3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
Currently the forward threader isn't limited as to the search space
it explores and with it now using path-ranger for simplifying
conditions it runs into it became pretty slow for degenerate cases
like compiling insn-emit.cc for RISC-V esp. when compiling for
a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
The following makes the forward threader honor the search space
limit I introduced for the backward threader. This reduces
compile-time from minutes to seconds for the testcase in PR116166.
Note this wasn't necessary before we had ranger but with ranger
the work we do is quadatic in the length of the threading path
we build up (the same is true for the backwards threader).
PR tree-optimization/116166
* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
Add limit parameter.
(jump_threader::thread_through_normal_block): Likewise.
* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
Honor and decrement limit parameter.
(jump_threader::thread_through_normal_block): Likewise.
(jump_threader::thread_across_edge): Initialize limit from
param_max_jump_thread_paths and pass it down to workers.

From 4d0a333ef13e2da140cd44c4941b20f48a80dc0f Mon Sep 17 00:00:00 2001
From: Hannes Braun <hannes@hannesbraun.net>
Date: Thu, 20 Feb 2025 15:09:41 +0100
Subject: [PATCH] arm: Fix signedness of vld1q intrinsic parms [PR118942]
vld1q_s8_x3, vld1q_s16_x3, vld1q_s8_x4 and vld1q_s16_x4 were expecting
pointers to unsigned integers. These parameters should be pointers to
signed integers.
gcc/ChangeLog:
PR target/118942
* config/arm/arm_neon.h (vld1q_s8_x3): Use int8_t instead of
uint16_t.
(vld1q_s16_x3): Use int16_t instead of uint16_t.
(vld1q_s8_x4): Likewise.
(vld1q_s16_x4): Likewise.
gcc/testsuite/ChangeLog:
PR target/118942
* gcc.target/arm/simd/vld1q_base_xN_1.c: Add -Wpointer-sign.

Subject: [PATCH 1/4] aarch64: Fix invalid nested subregs [PR115464]
The testcase extracts one arm_neon.h vector from a pair (one subreg)
and then reinterprets the result as an SVE vector (another subreg).
Each subreg makes sense individually, but we can't fold them together
into a single subreg: it's 32 bytes -> 16 bytes -> 16*N bytes,
but the interpretation of 32 bytes -> 16*N bytes depends on
whether N==1 or N>1.
Since the second subreg makes sense individually, simplify_subreg
should bail out rather than ICE on it. simplify_gen_subreg will
then do the same (because it already checks validate_subreg).
This leaves simplify_gen_subreg returning null, requiring the
caller to take appropriate action.
I think this is relatively likely to occur elsewhere, so the patch
adds a helper for forcing a subreg, allowing a temporary pseudo to
be created where necessary.
I'll follow up by using force_subreg in more places. This patch
is intended to be a minimal backportable fix for the PR.

Subject: [PATCH 2/4] aarch64: Use force_subreg in more places
This patch makes the aarch64 code use force_subreg instead of
simplify_gen_subreg in more places. The criteria were:
(1) The code is obviously specific to expand (where new pseudos
can be created).
(2) The value is obviously an rvalue rather than an lvalue.
(3) The offset wasn't a simple lowpart or highpart calculation;
a later patch will deal with those.

Subject: [PATCH 4/4] Add force_lowpart_subreg
optabs had a local function called lowpart_subreg_maybe_copy
that is very similar to the lowpart version of force_subreg.
This patch adds a force_lowpart_subreg wrapper around
force_subreg and uses it in optabs.cc.
The only difference between the old and new functions is that
the old one asserted success while the new one doesn't.
It's common not to assert elsewhere when taking subregs;
normally a null result is enough.
Later patches will make more use of the new function.
gcc/
* explow.h (force_lowpart_subreg): Declare.
* explow.cc (force_lowpart_subreg): New function.
* optabs.cc (lowpart_subreg_maybe_copy): Delete.
(expand_absneg_bit): Use force_lowpart_subreg instead of
lowpart_subreg_maybe_copy.
(expand_copysign_bit): Likewise.
(cherry picked from commit 5f40d1c0cc6ce91ef28d326b8707b3f05e6f239c)

Subject: [PATCH] libquadmath: Fix up libquadmath/math/sqrtq.c compilation in
some powerpc* configurations [PR116007]
My PR114623 change started using soft-fp.h and quad.h for the sqrtq implementation.
Unfortunately, that seems to fail building in some powerpc* configurations, where
TFmode isn't available.
quad.h has:
#ifndef TFtype
typedef float TFtype __attribute__ ((mode (TF)));
#endif
and uses TFtype. quad.h has:
/* Define the complex type corresponding to __float128
("_Complex __float128" is not allowed) */
#if (!defined(_ARCH_PPC)) || defined(__LONG_DOUBLE_IEEE128__)
typedef _Complex float __attribute__((mode(TC))) __complex128;
#else
typedef _Complex float __attribute__((mode(KC))) __complex128;
#endif
with the conditional and KCmode use added during porting of libquadmath
to powerpc*, so I've just defined TFtype for powerpc when __LONG_DOUBLE_IEEE128__
isn't defined; I could define it to float __attribute__ ((mode (KF))) but it
seemed easier to just define it to __float128 which should do the same thing.
2024-08-03 Jakub Jelinek <jakub@redhat.com>
PR target/116007
* math/sqrtq.c (TFtype): For PowerPC without __LONG_DOUBLE_IEEE128__
define to __float128 before including soft-fp.h and quad.h.

Subject: [PATCH] tree-optimization/116166 - forward jump-threading going wild
Currently the forward threader isn't limited as to the search space
it explores and with it now using path-ranger for simplifying
conditions it runs into it became pretty slow for degenerate cases
like compiling insn-emit.cc for RISC-V esp. when compiling for
a host with LOGICAL_OP_NON_SHORT_CIRCUIT disabled.
The following makes the forward threader honor the search space
limit I introduced for the backward threader. This reduces
compile-time from minutes to seconds for the testcase in PR116166.
Note this wasn't necessary before we had ranger but with ranger
the work we do is quadatic in the length of the threading path
we build up (the same is true for the backwards threader).
PR tree-optimization/116166
* tree-ssa-threadedge.h (jump_threader::thread_around_empty_blocks):
Add limit parameter.
(jump_threader::thread_through_normal_block): Likewise.
* tree-ssa-threadedge.cc (jump_threader::thread_around_empty_blocks):
Honor and decrement limit parameter.
