[gcc r15-934] C23: allow aliasing for types derived from structs with variable size
https://gcc.gnu.org/g:d2cfe8a73b3c4195a25cde28e1641ef36ebb08c1
commit r15-934-gd2cfe8a73b3c4195a25cde28e1641ef36ebb08c1
Author: Martin Uecker
Date: Fri May 24 12:35:27 2024 +0200
C23: allow aliasing for types derived from structs with variable size
Previously, we set the aliasing set of structures with variable size
struct foo { int x[n]; char b; };
to zero. The reason is that such types can be compatible to diffrent
structure types which are incompatible.
struct foo { int x[2]; char b; };
struct foo { int x[3]; char b; };
But it is not enough to set the aliasing set to zero, because derived
types would then still end up in different equivalence classes even
though they might be compatible. Instead those types should be set
to structural equivalency. We also add checking assertions that
ensure that TYPE_CANONICAL is set correctly for all tagged types.
gcc/c/
* c-decl.cc (finish_struct): Do not set TYPE_CANONICAL for
structure or unions with variable size.
* c-objc-common.cc (c_get_alias_set): Do not set alias set to zero.
* c-typeck.cc (comptypes_verify): New function.
(comptypes,comptypes_same_p,comptypes_check_enum_int): Add
assertion.
(comptypes_equiv_p): Add assertion that ensures that compatible
types have the same equivalence class.
(tagged_types_tu_compatible_p): Remove now unneeded special case.
gcc/testsuite/
* gcc.dg/gnu23-tag-alias-8.c: New test.

commit r15-933-g867d1264fe71d4291194373d1a1c409cac97a597

C: allow aliasing of compatible types derived from enumeral types [PR115157]
Aliasing of enumeral types with the underlying integer is now allowed
by setting the aliasing set to zero. But this does not allow aliasing
of derived types which are compatible as required by ISO C. Instead,
initially set structural equality. Then set TYPE_CANONICAL and update
pointers and main variants when the type is completed (as done for
structures and unions in C23).

I've set up binfmt handlers so that I can execute foreign binaries. So given a root filesystem, I can chroot into it and do whatever I need. As far as dejagnu is concerned it looks like the native system. Interesting. In a Docker setup (or similar container)? I've got docker containers for some of these. m68k, alpha, s390 for example. They're based off debian base images. I don't have anything for sparc and I don't see a base image to build from. If there was a base image, then a Dockerfile like this would get you started: FROM sparc64/debian:latest # Basic environment variables so we can apt-get without interactive prompts ENV LC_ALL C ENV DEBIAN_FRONTEND noninteractive ENV TZ=Etc/UTC RUN apt-get update && apt-get -y install gcc dejagnu binutils default-jre-headless git build-essential autoconf bison flex gawk make texinfo help2man libncurses5-dev python3-dev python3-distutils libtool libtool-bin unzip wget curl rsync texinfo g++ libmpc-dev libgmp-dev libmpfr-dev libgmp-dev python3 libisl-dev rsync vim automake autoconf autotools-dev unzip help2man libtool libtool-bin sudo curl wget pyt hon3-dev bzip2 xz-utils gdb bc libssl-dev libelf-dev With the lack of an existing docker image, you can probably use debootstrap to construct an initial chroot, the import that into docker, adding whatever bits you need to do the build (ie, compilers, dejagnu, make, texinfo, blah blah blah) via apt until it works. It's been a while since I've done it, but I'm pretty sure that's how I got things going on the sh4 and sh4eb platforms. The JRE bits are only needed because these get launched as a docker swarm service and thus need to connect to the Jenkins server using JNLP. Some of the packages are only needed for kernel builds or glibc builds. Jeff

[to-be-committed] [RISC-V] Use Zbkb for general 64 bit constants when profitable
Basically this adds the ability to generate two independent constants
during synthesis, then bring them together with a pack instruction.
Thus we never need to go out to the constant pool when zbkb is enabled.
The worst sequence we ever generate is
lui+addi+lui+addi+pack
Obviously if either half can be synthesized with just a lui or just an
addi, then we'll DTRT automagically. So for example:
unsigned long foo_0xf857f2def857f2de(void) {
return 0x14252800;
}
The high and low halves are just a lui. So the final synthesis is:
li a5,671088640# 15[c=4 l=4] *movdi_64bit/1
li a0,337969152# 16[c=4 l=4] *movdi_64bit/1
packa0,a5,a0# 17[c=12 l=4] riscv_xpack_di_si_2
On the implementation side, I think the bits I've put in here likely can
be used to handle the repeating constant case for !zbkb. I think it
likely could be used to help capture cases where the upper half can be
derived from the lower half (say by turning a bit on or off, shifting or
something similar). The key in both of these cases is we need a
temporary register holding an intermediate value.
Ventana's internal tester enables zbkb, but I don't think any of the
other testers currently exercise zbkb. We'll probably want to change
that at some point, but I don't think it's super-critical yet.
While I can envision a few more cases where we could improve constant
synthesis, No immediate plans to work in this space, but if someone is
interested, some thoughts are recorded here:

[PATCHv2, rs6000] Optimize vector construction with two vector doubleword loads [PR103568]
Hi,
This patch optimizes vector construction with two vector doubleword loads.
It generates an optimal insn sequence as "xxlor" has lower latency than
"mtvsrdd" on Power10.
Compared with previous version, the main change is to use "isa" attribute
to guard "lxsd" and "lxsdx".
https://gcc.gnu.org/pipermail/gcc-patches/2024-May/653103.html
Bootstrapped and tested on powerpc64-linux BE and LE with no
regressions. OK for the trunk?
Thanks
Gui Haochen
ChangeLog
rs6000: Optimize vector construction with two vector doubleword loads
When constructing a vector by two doublewords from memory, originally it
does
ld 10,0(3)
ld 9,0(4)
mtvsrdd 34,9,10
An optimal sequence on Power10 should be
lxsd 0,0(4)
lxvrdx 1,0,3
xxlor 34,1,32
This patch does this optimization by insn combine and split.

In ix86_override_options_after_change, calls to ix86_default_align
and ix86_recompute_optlev_based_flags will cause mismatched target
opt_set when doing cl_optimization_restore. Move them back to
ix86_option_override_internal to solve the issue.

Question about generating vpmovzxbd instruction without using the interfaces in immintrin.h
Hi,
I've recently been trying to hand-write code to trigger automatic
vectorization optimizations in GCC on Intel x86 machines (without
using the interfaces in immintrin.h), but I'm running into a problem
where I can't seem to get the concise `vpmovzxbd` or similar
instructions.
My requirement is to convert 8 `uint8_t` elements to `int32_t` type
and print the output. If I use the interface (_mm256_cvtepu8_epi32) in
immintrin.h, the code is as follows:
int immintrin () {
int size = 1, offset = 3;
uint8_t* a = malloc(sizeof(char) * size);
__v8si b = (__v8si)_mm256_cvtepu8_epi32(*(__m128i *)(a + offset));
for (int i = 0; i < 8; i++) {
printf("%d\n", b[i]);
}
}
After compiling with -mavx2 -O3, you can get concise and efficient
instructions. (You can see it here: https://godbolt.org/z/8ojzdav47)
But if I do not use this interface and instead use a for-loop or the
`__builtin_convertvector` interface provided by GCC, I cannot achieve
the above effect. The code is as follows:
typedef uint8_t v8qiu __attribute__ ((__vector_size__ (8)));
int forloop () {
int size = 1, offset = 3;
uint8_t* a = malloc(sizeof(char) * size);
v8qiu av = *(v8qiu *)(a + offset);
__v8si b = {};
for (int i = 0; i < 8; i++) {
b[i] = (a + offset)[i];
}
for (int i = 0; i < 8; i++) {
printf("%d\n", b[i]);
}
}
int builtin_cvt () {
int size = 1, offset = 3;
uint8_t* a = malloc(sizeof(char) * size);
v8qiu av = *(v8qiu *)(a + offset);
__v8si b = __builtin_convertvector(av, __v8si);
for (int i = 0; i < 8; i++) {
printf("%d\n", b[i]);
}
}
The instructions generated by both functions are redundant and
complex, and are quite difficult to read compared to calling
`_mm256_cvtepu8_epi32` directly. (You can see it here as well:
https://godbolt.org/z/8ojzdav47)
What I want to ask is: How should I write the source code to get
assembly instructions similar to directly calling
_mm256_cvtepu8_epi32?
Or would it be easier if I modified the GIMPLE directly? But it seems
that there is no relevant expression or interface directly
corresponding to `vpmovzxbd` in GIMPLE.
Thanks

Interesting. In a Docker setup (or similar container)? If so, care to share the Dockerfile (or equivalent)?

I'll try to cook up something, likely Debian-based...later this decade, aiming for suitability in contrib/. brgds, H-P ps. my hyperbolic time guesstimates somehow still expire too soon!

[PATCH v2] aarch64: Add vector floating point extend pattern [PR113880, PR113869]
This patch adds vector floating point extend pattern for V2SF->V2DF and
V4HF->V4SF conversions by renaming the existing aarch64_float_extend_lo_
pattern to the standard optab one, i.e., extend2. This allows the
vectorizer to vectorize certain floating point widening operations for the
aarch64 target.
PR target/113880
PR target/113869
gcc/ChangeLog:
* config/aarch64/aarch64-builtins.cc (VAR1): Remap float_extend_lo_
builtin codes to standard optab ones.
* config/aarch64/aarch64-simd.md (aarch64_float_extend_lo_):
Rename
to...
(extend2): ... This.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/extend-vec.c: New test.

[Bug rtl-optimization/115297] New: [14 regression] alpha: ICE in simplify_subreg, at simplify-rtx.cc:7554 with -O1
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115297
Bug ID: 115297
Summary: [14 regression] alpha: ICE in simplify_subreg, at
simplify-rtx.cc:7554 with -O1
Product: gcc
Version: 14.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: matoro_gcc_bugzilla at matoro dot tk
Target Milestone: ---
Target: alpha-unknown-linux-gnu
Created attachment 58314
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58314=edit
gdb context and complete backtrace
Found this while building kernel with gcc-14. This reproduces on cross, so
using that as an example.
Minimized:
enum { BPF_F_USER_BUILD_ID } __bpf_get_stack_size;
long __bpf_get_stack_flags, bpf_get_stack___trans_tmp_2;
void bpf_get_stack() {
unsigned elem_size;
int err = elem_size = __bpf_get_stack_flags ?: sizeof(long);
if (__builtin_expect(__bpf_get_stack_size % elem_size, 0))
bpf_get_stack___trans_tmp_2 = err;
}
$ alpha-unknown-linux-gnu-gcc-14 -O1 -c stackmap.i
during RTL pass: combine
stackmap.i: In function ‘bpf_get_stack’:
stackmap.i:8:1: internal compiler error: in simplify_subreg, at
simplify-rtx.cc:7554

[PATCH v5] Match: Support more form for scalar unsigned SAT_ADD
From: Pan Li
Update in v5
* Fix some doc build error.
Log in v4:
After we support one gassign form of the unsigned .SAT_ADD, we
would like to support more forms including both the branch and
branchless. There are 5 other forms of .SAT_ADD, list as below:
Form 1:
#define SAT_ADD_U_1(T) \
T sat_add_u_1_##T(T x, T y) \
{ \
return (T)(x + y) >= x ? (x + y) : -1; \
}
Form 2:
#define SAT_ADD_U_2(T) \
T sat_add_u_2_##T(T x, T y) \
{ \
T ret; \
T overflow = __builtin_add_overflow (x, y, ); \
return (T)(-overflow) | ret; \
}
Form 3:
#define SAT_ADD_U_3(T) \
T sat_add_u_3_##T (T x, T y) \
{ \
T ret; \
return __builtin_add_overflow (x, y, ) ? -1 : ret; \
}
Form 4:
#define SAT_ADD_U_4(T) \
T sat_add_u_4_##T (T x, T y) \
{ \
T ret; \
return __builtin_add_overflow (x, y, ) == 0 ? ret : -1; \
}
Form 5:
#define SAT_ADD_U_5(T) \
T sat_add_u_5_##T(T x, T y) \
{ \
return (T)(x + y) < x ? -1 : (x + y); \
}
Take the forms 3 of above as example:
uint64_t
sat_add (uint64_t x, uint64_t y)
{
uint64_t ret;
return __builtin_add_overflow (x, y, ) ? -1 : ret;
}
Before this patch:
uint64_t sat_add (uint64_t x, uint64_t y)
{
long unsigned int _1;
long unsigned int _2;
uint64_t _3;
__complex__ long unsigned int _6;
;; basic block 2, loop depth 0
;;pred: ENTRY
_6 = .ADD_OVERFLOW (x_4(D), y_5(D));
_2 = IMAGPART_EXPR <_6>;
if (_2 != 0)
goto ; [35.00%]
else
goto ; [65.00%]
;;succ: 4
;;3
;; basic block 3, loop depth 0
;;pred: 2
_1 = REALPART_EXPR <_6>;
;;succ: 4
;; basic block 4, loop depth 0
;;pred: 3
;;2
# _3 = PHI <_1(3), 18446744073709551615(2)>
return _3;
;;succ: EXIT
}
After this patch:
uint64_t sat_add (uint64_t x, uint64_t y)
{
long unsigned int _12;
;; basic block 2, loop depth 0
;;pred: ENTRY
_12 = .SAT_ADD (x_4(D), y_5(D)); [tail call]
return _12;
;;succ: EXIT
}
The flag '^' acts on cond_expr will generate matching code similar as below:
else if (gphi *_a1 = dyn_cast (_d1))
{
basic_block _b1 = gimple_bb (_a1);
if (gimple_phi_num_args (_a1) == 2)
{
basic_block _pb_0_1 = EDGE_PRED (_b1, 0)->src;
basic_block _pb_1_1 = EDGE_PRED (_b1, 1)->src;
basic_block _db_1 = safe_dyn_cast (*gsi_last_bb (_pb_0_1)) ?
_pb_0_1 : ...
basic_block _other_db_1 = safe_dyn_cast (*gsi_last_bb
(_pb_0_1)) ? _pb_1_1 : ...
gcond *_ct_1 = safe_dyn_cast (*gsi_last_bb (_db_1));
if (_ct_1 && EDGE_COUNT (_other_db_1->preds) == 1
&& EDGE_COUNT (_other_db_1->succs) == 1
&& EDGE_PRED (_other_db_1, 0)->src == _db_1)
{
tree _cond_lhs_1 = gimple_cond_lhs (_ct_1);
tree _cond_rhs_1 = gimple_cond_rhs (_ct_1);
tree _p0 = build2 (gimple_cond_code (_ct_1), boolean_type_node,
_cond_lhs_1, ...);
bool _arg_0_is_true_1 = gimple_phi_arg_edge (_a1, 0)->flags &
EDGE_TRUE_VALUE;
tree _p1 = gimple_phi_arg_def (_a1, _arg_0_is_true_1 ? 0 : 1);
tree _p2 = gimple_phi_arg_def (_a1, _arg_0_is_true_1 ? 1 : 0);
switch (TREE_CODE (_p0))
...
The below test suites are still running, will update it later.
* The x86 bootstrap test.
* The x86 fully regression test.
* The riscv fully regression test.
gcc/ChangeLog:
* doc/match-and-simplify.texi: Add doc for the matching flag '^'.
* genmatch.cc (enum expr_flag): Add new enum for expr flag.
(dt_node::gen_kids_1): Add cond_expr and flag handling.
(dt_operand::gen_phi_on_cond): Add new func to gen phi matching
on cond_expr.
(parser::parse_expr): Add handling for the expr flag '^'.
* match.pd: Add more form for unsigned .SAT_ADD.
* tree-ssa-math-opts.cc (match_saturation_arith): Rename from.
(match_assign_saturation_arith): Rename to.
(match_phi_saturation_arith): Add new func impl to match the
.SAT_ADD when phi.
(math_opts_dom_walker::after_dom_children): Add phi matching
try for all gimple phi stmt.

[committed] i386: Rewrite bswaphi2 handling [PR115102]
Introduce *bswaphi2 instruction pattern and enable bswaphi2 expander
also for non-movbe targets. The testcase:
unsigned short bswap8 (unsigned short val)
{
return ((val & 0xff00) >> 8) | ((val & 0xff) << 8);
}
now expands through bswaphi2 named expander.
Rewrite bswaphi_lowpart insn pattern as bswaphisi2_lowpart in the RTX form
that combine pass can use to simplify:
Trying 6, 9, 8 -> 10:
6: r99:SI=bswap(r103:SI)
9: {r107:SI=r103:SI&0x;clobber flags:CC;}
REG_DEAD r103:SI
REG_UNUSED flags:CC
8: {r106:SI=r99:SI 0>>0x10;clobber flags:CC;}
REG_DEAD r99:SI
REG_UNUSED flags:CC
10: {r104:SI=r106:SI|r107:SI;clobber flags:CC;}
REG_DEAD r107:SI
REG_DEAD r106:SI
REG_UNUSED flags:CC
Successfully matched this instruction:
(set (reg:SI 104 [ _8 ])
(ior:SI (and:SI (reg/v:SI 103 [ val ])
(const_int -65536 [0x]))
(lshiftrt:SI (bswap:SI (reg/v:SI 103 [ val ]))
(const_int 16 [0x10]
allowing combination of insns 6, 8, 9 and 10
when compiling the following testcase:
unsigned int bswap8 (unsigned int val)
{
return (val & 0x) | ((val & 0xff00) >> 8) | ((val & 0xff) << 8);
}
to produce:
movl%edi, %eax
xchgb %ah, %al
ret
The expansion now always goes through a clobberless form of the bswaphi
instruction. The instruction is conditionally converted to a rotate at
peephole2 pass. This significantly simplifies bswaphisi2_lowpart
insn pattern attributes.
PR target/115102
gcc/ChangeLog:
* config/i386/i386.md (bswaphi2): Also enable for !TARGET_MOVBE.
(*bswaphi2): New insn pattern.
(bswaphisi2_lowpart): Rename from bswaphi_lowpart. Rewrite
insn RTX to match the expected form of the combine pass.
Remove rol{w} alternative and corresponding attributes.
(bswsaphisi2_lowpart peephole2): New peephole2 pattern to
conditionally convert bswaphisi2_lowpart to rotlhi3_1_slp.
(bswapsi2): Update expander for rename.
(rotlhi3_1_slp splitter): Conditionally split to bswaphi2.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr115102.c: New test.

[Bug target/115102] [SH] GCC misunderstands swap.b instruction

i386: Rewrite bswaphi2 handling [PR115102]
Introduce *bswaphi2 instruction pattern and enable bswaphi2 expander
also for non-movbe targets. The testcase:
unsigned short bswap8 (unsigned short val)
{
return ((val & 0xff00) >> 8) | ((val & 0xff) << 8);
}
now expands through bswaphi2 named expander.
Rewrite bswaphi_lowpart insn pattern as bswaphisi2_lowpart in the RTX form
that combine pass can use to simplify:
Trying 6, 9, 8 -> 10:
6: r99:SI=bswap(r103:SI)
9: {r107:SI=r103:SI&0x;clobber flags:CC;}
REG_DEAD r103:SI
REG_UNUSED flags:CC
8: {r106:SI=r99:SI 0>>0x10;clobber flags:CC;}
REG_DEAD r99:SI
REG_UNUSED flags:CC
10: {r104:SI=r106:SI|r107:SI;clobber flags:CC;}

when compiling the following testcase:

}
to produce:

The expansion now always goes through a clobberless form of the bswaphi
instruction. The instruction is conditionally converted to a rotate at
peephole2 pass. This significantly simplifies bswaphisi2_lowpart
insn pattern attributes.

[PATCH v3 3/6] btf: refactor and simplify implementation
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 for non-LTO builds. In LTO builds, BTF must be emitted at early_finish, so some VAR records may be emitted for variables which are later optimized away. 3) Some additional assembler comments have been added with more information for debugging. gcc/ * btfout.cc (struct btf_datasec_entry): New.

A pure function -- by definition -- has no side effects. These things have side effects. What you mean is this is *an implementation* for C++ functions without a generic implementation.

This does not belong in this patch. Do not send "rs6000" patches that touch anything outside of config/rs6000/ and similar, certainly not in config/something-else/!

[PATCH v3 5/6] 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.

[PATCH v3 6/6] opts: allow any combination of DWARF, CTF, BTF
Previously it was not supported to generate both CTF and BTF debug info
in the same compiler run, as both formats made incompatible changes to
the same internal data structures.
With the structural change in the prior patches, in particular the
guarantee that CTF will always be fully emitted before any BTF
translation occurs, there is no longer anything preventing generation
of both CTF and BTF at the same time. This patch changes option parsing
to allow any combination of -gdwarf, -gctf, and -gbtf at the same time.

[PATCH v3 4/6] btf: add -fprune-btf option
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 10x or more, as seen on average when compiling Linux
kernel BPF selftests. 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.
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. Note that with or without pruning, BTF_KIND_VAR
entries are only generated for variables present in the final
object - unused static variables or variables completely optimized
away must not have VAR entries in BTF.
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.

[PATCH v3 2/6] ctf: use pointers instead of IDs internally
This patch replaces all inter-type references in the ctfc internal data

A couple of small updates in the BPF backend are included to make it
compatible with the change.
This change is only to the in-memory representation of various CTF

[PATCH v3 1/6] ctf, btf: restructure CTF/BTF emission
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),
for all targets in non-LTO builds, rather than being emitted at
early_finish for targets other than BPF CO-RE. In LTO builds,
BTF is emitted at early_finish as before.
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, because the calculation of the BTF to be
emitted is not moved by this patch, only the write-out.
The changes are transparent to both CTF and BTF emission.

[PATCH v3 0/6] btf: refactor and add pruning option
[v2: https://gcc.gnu.org/pipermail/gcc-patches/2024-May/650482.html Changes from v2: - Handle -flto when generating BTF (in patch 1). For LTO builds, BTF is emitted at early_finish as before. For non-LTO builds, BTF will be emitted at (late) finish for all targets. - Move the option parsing change to allow -gbtf and -gctf together to the end of the series. This patch is relatively separate from the other changes, and only depends upon patch 1. - Include Indu's various comments and suggestions throughout the series. - Fix a few GNU style issues with indentation and long lines. - Fix the special handling for .maps section variables in BTF in patch 4. Previously the type marking was too aggressive, and undid nearly all the pruning in some kernel selftests. In one test this fix reduced the emitted BTF from over 6000 types to about 200 types, very similar to clang's output for the same test. ] This patch series signficantly refactors the BTF generation in gcc, making it simpler and easier to understand, extend and maintain. It also introduces an optional algorithm to "prune" BTF information before emission. This pruning is meant to be used for BPF programs, to alleviate the massive bloating of BTF information caused by including Linux kernel internal headers. The pruning is designed to be compatible with the unconditional pruning performed by the LLVM BPF backend when generating BTF information. While the changes are fairly significant, there is no actual change in emitted BTF information (unless pruning is enabled), other than bug fixes and small additions to the assembler debug comments. Patch 1 restructures the emission of CTF and BTF information, with the result that CTF is always completely generated and emitted before any BTF-related procedures are run. BTF emission is moved to late finish for all targets, except when building with -flto. Patch 2 changes the data structures shared by CTF and BTF to use pointers rather than type IDs for all inter-type references. This change is completely transparent to both CTF and BTF. Patch 3 heavily refactors btfout.cc to take advantage of the prior changes and significantly simplify the BTF implementation. The changes are nearly transparent, however some small but important improvements are also made possible by the refactor, such as fixing PR113566 for non-LTO builds. Patch 4 adds a new option to perform pruning of the BTF information before emission. This is intended to be used for BPF programs which often include kernel headers, and in many cases reduces the size of the resulting BTF information by a factor of 10. Patch 5 makes BTF pruning work with BPF CO-RE, and enables the pruning by default in the BPF backend. Patch 6 takes advantage of the prior changes, and removes the restriction on generating both CTF and BTF in the same compiler run, allowing for any combinaion of -gdwarf, -gctf and -gbtf. Tested on x86_64-linux-gnu, and on x86_64-linux-gnu host for bpf-unknown-none target. Also tested by compiling and runninng Linux kernel BPF selftests. No known regressions.

Nice investigation!

IMO we should just skip aarch64-sve.exp if the options explicitly disable
SVE. But that's separate work. I'll try it once this patch is in.

Might be better to make this p([1-3]), so that we disallow any registers
that would cause a spill.

this would be:

[ , Upa , Upa , Upa ; yes ] \t%0.b, %1/z,
%2.b, %3.b

Same idea for the rest.
I tried this on:
--
#include
void use (svbool_t, svbool_t, svbool_t);
void
f1 (svbool_t p0, svbool_t p1, svbool_t p2, int n, svbool_t *ptr)
{
while (n--)
p2 = svand_z (p0, p1, p2);
*ptr = p2;
}
void
f2 (svbool_t p0, svbool_t p1, svbool_t p2, svbool_t *ptr)
{
*ptr = svand_z (p0, p1, p2);
}
void
f3 (svbool_t p0, svbool_t p1, svbool_t p2, svbool_t *ptr)
{
use (svand_z (p0, p1, p2), p1, p2);
}
void
f4 (svbool_t p0, svbool_t p1, svbool_t p2, svbool_t *ptr)
{
use (p0, svand_z (p0, p1, p2), p2);
}
void
f5 (svbool_t p0, svbool_t p1, svbool_t p2, svbool_t *ptr)
{
use (p0, p1, svand_z (p0, p1, p2));
}

and it seemed to produce the right output:
--
f1:

.p2align 5,,15
.L3:

Probably best to leave this out. All alternatives require operand 3
to match operand 0. So operands 1 and 2 will only match operand 0
if they're the same as operand 3. In that case it'd be better to
allow the sharing rather than force the same value to be stored
in two registers.
That is, if op1 != op3 && op2 != op3 then we get what we want
naturally, regardless of tuning.
The same thing would apply to the BRKN instances of :

but I think we should keep this factoring/abstraction and just add

Target specific code are added in rs6000-mem-fusion.cc and additional virtual
function implementation required for rs6000 are added in aarch64-ldp-fusion.cc.
Bootstrapped and regtested for aarch64-linux-gnu and powerpc64-linux-gnu.
Thanks & Regards

aarch64, rs6000, middle-end: Add implementation for different targets for pair
mem fusion
Common infrastructure using generic code for pair mem fusion of different
targets.
rs6000 target specific specific code implements virtual functions defined
by generic code.
Code is implemented with pure virtual functions to interface with target
code.
Target specific code are added in rs6000-mem-fusion.cc and additional virtual
function implementation required for rs6000 are added in aarch64-ldp-fusion.cc.
2024-05-31 Ajit Kumar Agarwal
gcc/ChangeLog:
* config/aarch64/aarch64-ldp-fusion.cc: Add target specific
implementation of additional virtual functions added in pair_fusion
struct.
* config/rs6000/rs6000-passes.def: New mem fusion pass
before pass_early_remat.
* config/rs6000/rs6000-mem-fusion.cc: Add new pass.
Add target specific implementation using pure virtual
functions.
* config.gcc: Add new object file.
* config/rs6000/rs6000-protos.h: Add new prototype for mem
fusion pass.
* config/rs6000/t-rs6000: Add new rule.
* rtl-ssa/accesses.h: Moved set_is_live_out_use as public
from private.
gcc/testsuite/ChangeLog:
* g++.target/powerpc/me-fusion.C: New test.
* g++.target/powerpc/mem-fusion-1.C: New test.
* gcc.target/powerpc/mma-builtin-1.c: Modify test.

Bug ID: 115294
Summary: [15 regression] dg-additional-files-options change
broke several testsuites
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: aoliva at gcc dot gnu.org
Target Milestone: ---
Between 20240529 (18f477980c8597fe3dca2c2e8bd533c0c2b17aa6) and 20240530
(71899d6b4e18145f005046681208db0137c95ede),
several testsuite results were lost completely.
libatomic, libgomp, libitm, and libphobos are affected. In each case, the
test logs show a variation of
ERROR: tcl error sourcing

I'm seeing this on both i386-pc-solaris2.11 and x86_64-pc-linux-gnu; most
likely
this happens everywhere.

I see at least five completely different patches in this email thread,
with different subjects and all.

It always was like that. Some people say 79, that is fine too.
It mostly irks me because lines that end in : and then a lot of empty
space look like peoople used one of those awful "write the changelog for
me" helper things, that *at best* *slow you down*, and always (always!)
cause worse results.

Line length in source code is 79 or 80. In email it is 72 or so. This
has not changed since the dawn of time :-)

bl, bcl, what's the difference (bit 4 is, heh, 16 vs. 18). Read bl if
you want -- the point is that there are crlogical insns before the
branch-and-link.

4 - length does not make any sense /an sich/, it *is* magic.
It is not clear it is correct at all, either.

Yeah, things don't work that way. If you need help, *ask* for that.
Don't pretend a patch is good if you have doubts yourself!

I want a patch submission that is a) understandable and b) a good thing
to have. If a patch leaves me wondering what is going on at all, that
is not ideal ;-)

[Bug sanitizer/84508] Load of misaligned address using _mm_load_sd

Interesting, yes some entries explicitly say the memory can be unaligned, some don't. But I don't think we should read that as alignment required being the default if not stated. Every intrinsic that does require alignment explicitly says so. (Like _mm_load_si128.) We could make the same argument in the other direction, that if an alignment requirement isn't mentioned, we should assume there isn't one. And I already posted earlier about why we shouldn't assume C semantics based on the pointer type as Andrew Pinski had thought. Intel's intrinsic docs were originally written for ICC (classic), which takes intrinsics very literally: an intrinsic in the C source will (almost?) always compile to the corresponding asm instruction. And presumably not optimizing based on pointer-alignment UB even on a deref. And definitely not on strict-aliasing UB. So the C defaults for deref of a double* or __m64* shouldn't be assumed even when the docs don't say anything about alignment. They also don't mention aliasing but we know from Intel's examples of how to use intrinsics (I think) that the load/store intrinsics are all may_alias accesses. Intel's current ICX compiler is based on LLVM which does care about aliasing and alignment UB when optimizing, but their intrinsic docs still read like they're thinking more in terms of asm than in terms of the C abstract machine. Probably they haven't been rewritten with that in mind since they implement them (in their own compilers) so they Just Work even when aliasing other types or without alignment.

A testcase specifically for this would be good, yes. Where you can say at the top of the file "This tests that ... [X and Y]" :-) Segher
