Seems we already handle delete expressions the way the DR clarifies, so this patch just adds a testcase which verifies that. 2024-09-25 Jakub Jelinek <jakub@redhat.com> * g++.dg/DRs/dr2728.C: New test.

In expressions like (a != b || ((a ^ b) & c) == d) and (a != b || (a ^ b) == c), (a ^ b) is folded to false. In the equivalent expressions (((a ^ b) & c) == d || a != b) and ((a ^ b) == c || a != b) this is not happening. This patch adds the following simplifications in match.pd: ((a ^ b) & c) cmp d || a != b --> 0 cmp d || a != b (a ^ b) cmp c || a != b --> 0 cmp c || a != b PR tree-optimization/114326 gcc/ChangeLog: * match.pd: Add two patterns to fold a ^ b to 0, when a == b. gcc/testsuite/ChangeLog: * gcc.dg/tree-ssa/fold-xor-and-or.c: New test. * gcc.dg/tree-ssa/fold-xor-or.c: New test.

wide_int_storage shows up high in the profile for the testcase in PR114855 where the apparent issue is that the conditional jump on 'precision' after the (inlined) memcpy stalls the pipeline due to the data dependence and required store-to-load forwarding. We can add scheduling freedom by instead testing precision as from the source which speeds up the function by 30%. I've applied the same logic to the copy CTOR. * wide-int.h (wide_int_storage::wide_int_storage): Branch on source precision to avoid data dependence on memcpy destination.

The following function: int foo(int *a, int j) { int k = j - 1; return a[j - 1] == a[k]; } does not fold to `return 1;` using -O2 or higher. The cause of this is that the expression `4 * j + (-4)` for the index computation is not folded to `4 * (j - 1)`. Existing simplifications that handle similar cases are applied when A == C, which is not the case in this instance. A previous attempt to address this issue is https://gcc.gnu.org/pipermail/gcc-patches/2024-April/649896.html This patch adds the following simplification in match.pd: (A * B) + (-C) -> (B - C/A) * A, if C a multiple of A which also handles cases where the index is j - 2, j - 3, etc. Bootstrapped for all languages and regression tested on x86-64 and aarch64.

Remove some ad-hoc simplification code in the forward threader, as the call into the ranger in m_simplifier->simplify() will handle anything we can do manually in simplify_control_stmt_condition_1. In PR114855, DOM time is reduced from 120s to 92s (-23%) and overall compilation time from 235s to 205s (-12%). The total thread count at -O1 is unchanged for the testcase. In our bootstrap .ii benchmark suite, I see we thread 3 threads less over all files at -O1. At -O2, the backward threader picks up one more, for no difference over all.

In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build flags to help catch problems in the library. This patch takes a different approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is defined. As a result, the testsuites will treat them as non-system-headers to get better warning coverage during regression testing of both gcc and libstdc++, not just when building the library. My rationale for the #ifdef instead of just removing the #pragma is the three G++ tests that want to test libstdc++ system header behavior, so we need a way to select it. This doesn't affect installed libraries, as they get their system-header status from the lookup path. But testsuite_flags --build-includes gives -I directives rather than -isystem. This patch doesn't change the headers in config/ because I'm not compiling with most of them, so won't see any warnings that need fixing. Adjusting them could happen later, or we can not bother. libstdc++-v3/ChangeLog: * acinclude.m4 (WARN_FLAGS): Remove -Wsystem-headers. * configure: Regenerate. * include/bits/algorithmfwd.h: #ifdef

Older versions of the OpenMP specification were not clear about what counted as device usage. Newer (like TR13) are rather clear. Hence, this commit adds GCC's target-used flag also when a 'declare target' or an 'interop' are encountered. (The latter only to Fortran as C/C++ parsing support is still missing.) TR13 also lists 'dispatch' as target-used construct (as it has the device clause) and 'device_safesync' as clause with global requirement property, but both are not yet supported in GCC. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_declare_target): Set target-used bit in omp_requires_mask. gcc/cp/ChangeLog: * parser.cc (cp_parser_omp_declare_target): Set target-used bit in omp_requires_mask. gcc/fortran/ChangeLog: * parse.cc (decode_omp_directive): Set target-used bit of omp_requires_mask when encountering the declare_target or interop directive. gcc/testsuite/ChangeLog: * gfortran.dg/gomp/interop-1.f90: Add dg-error for missing omp requires requirement and declare_variant usage. * gfortran.dg/gomp/requires-8.f90: Likewise.

For the testcase in PR114855 at -O1 add_store_equivs shows up as the main sink for bitmap_set_bit because it uses a bitmap to mark all seen insns by UID to make sure the forward walk in memref_used_between_p will find the insn in question. Given we do have a CFG here the functions operation is questionable, given memref_used_between_p together with the walk of all insns is obviously quadratic in the worst case that whole thing should be re-done ... but, for the testcase, using a sbitmap of size get_max_uid () + 1 gets bitmap_set_bit off the profile and improves IRA time from 15.58s (8%) to 3.46s (2%). Now, given above quadraticness I wonder whether we should instead gate add_store_equivs on optimize > 1 or flag_expensive_optimizations.

The following patch implements the C++23 P2718R0 paper - Wording for P2644R1 Fix for Range-based for Loop. The patch introduces a new option, -f{,no-}range-for-ext-temps so that user can control the behavior even in older C++ versions. The option is on by default in C++23 and later (-fno-range-for-ext-temps is an error in that case) and in the -std=gnu++11 ... -std=gnu++20 modes (one can use -fno-range-for-ext-temps to request previous behavior in that case), and is not enabled by default in -std=c++11 ... -std=c++20 modes but one can explicitly enable it with -frange-for-ext-temps. As all the temporaries from __for_range initialization should have life extended until the end of __for_range scope, this patch disables (for -frange-for-ext-temps and if !processing_template_decl) CLEANUP_POINT_EXPR wrapping of the __for_range declaration, also disables -Wdangling-reference warning as well as the rest of extend_ref_init_temps (we know the __for_range temporary is not TREE_STATIC and as all the temporaries from the initializer will be life extended, we shouldn't try to handle temporaries referenced by references any differently) and adds an extra push_stmt_list/pop_stmt_list before cp_finish_decl of __for_range and after end of the for body and wraps all that into CLEANUP_POINT_EXPR. I had to repeat that also for OpenMP range loops because those are handled differently. 2024-09-24 Jakub Jelinek <jakub@redhat.com> PR c++/107637 gcc/ * omp-general.cc (find_combined_omp_for, find_nested_loop_xform): Handle CLEANUP_POINT_EXPR like TRY_FINALLY_EXPR. * doc/invoke.texi (frange-for-ext-temps): Document.

We have been building a legacy libgcc_s.1 DSO to support code that was built with older compilers. From macOS 15, the unwinder no longer exports some of the symbols used in that library which (a) cuases bootstrap fail and (b) means that the legacy library is no longer useful. No open branch of GCC emits references to this library - and any already -built code that depends on the symbols would need rework anyway.

We currently do not expect comdat group of the guarded function to be set at the time of generating pre and post check function. However, in the case of an explicit instantiation, the guarded function has been added to a comdat group before generating contract check functions, which causes the observed ICE. Current assert removed and an additional check for comdat group of the guarded function added. With this change, the pre and post check functions get added to the same comdat group of the guarded function if the guarded function is already placed in a comdat group.

TR13 (pre-6.0) of the OpenMP spec says: "Each trait-property may only be specified once in a trait selector other than those in the construct selector set." and "If trait-property any is specified in the kind trait-selector of the device selector set or the target_device selector sets, no other trait-property may be specified in the same selector set." These restrictions (with slightly different wording) date back to OpenMP 5.1, but were not in 5.0 which was the basis for GCC's implementation. This patch adds a diagnostic, adds new testcases, and fixes some older testcases that include now-invalid selectors. gcc/ChangeLog * omp-general.cc (omp_check_context_selector): Reject other properties in the same selector set with kind(any).

This patch would like to fix the following ICE for -O2 -m32 of x86_64. during RTL pass: expand JackMidiAsyncWaitQueue.cpp.cpp: In function 'void DequeueEvent(unsigned int)': JackMidiAsyncWaitQueue.cpp.cpp:3:6: internal compiler error: in expand_fn_using_insn, at internal-fn.cc:263 3 | void DequeueEvent(unsigned frame) { | ^~~~~~~~~~~~ 0x27b580d diagnostic_context::diagnostic_impl(rich_location*, diagnostic_metadata const*, diagnostic_option_id, char const*, __va_list_tag (*) [1], diagnostic_t) ???:0 0x27c4a3f internal_error(char const*, ...) ???:0 0x27b3994 fancy_abort(char const*, int, char const*) ???:0 0xf25ae5 expand_fn_using_insn(gcall*, insn_code, unsigned int, unsigned int) ???:0 0xf2a124 expand_direct_optab_fn(internal_fn, gcall*, optab_tag, unsigned int) ???:0 0xf2c87c expand_SAT_SUB(internal_fn, gcall*) ???:0 We allowed the operand convert when matching SAT_SUB in match.pd, to support the zip benchmark SAT_SUB pattern. Aka, (convert? (minus (convert1? @0) (convert1? @1))) for below sample code. void test (uint16_t *x, unsigned b, unsigned n) { unsigned a = 0; register uint16_t *p = x; do { a = *--p; *p = (uint16_t)(a >= b ? a - b : 0); // Truncate after .SAT_SUB } while (--n); } The pattern match for SAT_SUB itself may also act on below scalar sample code too. unsigned long long GetTimeFromFrames(int); unsigned long long GetMicroSeconds(); void DequeueEvent(unsigned frame) { long long frame_time = GetTimeFromFrames(frame); unsigned long long current_time = GetMicroSeconds(); DequeueEvent(frame_time < current_time ? 0 : frame_time - current_time); } Aka: uint32_t a = (uint32_t)SAT_SUB(uint64_t, uint64_t); Then there will be a problem when ia32 or -m32 is given when compiling. Because we only check the lhs (aka uint32_t) type is supported by ifn instead of the operand (aka uint64_t). Mostly DImode is disabled for 32 bits target like ia32 or rv32gcv, and then trigger ICE when expanding. The below test suites are passed for this patch. * The rv64gcv fully regression test. * The x86 bootstrap test. * The x86 fully regression test. PR middle-end/116814 gcc/ChangeLog: * tree-ssa-math-opts.cc (build_saturation_binary_arith_call): Make ifn is_supported type check based on operand instead of lhs. gcc/testsuite/ChangeLog: * g++.dg/torture/pr116814-1.C: New test.

Under some circumstances we can end up picking a not relevant stmt as representative of a SLP node. Instead of skipping stmt analysis and declaring success we have to either ignore relevancy throughout the code base or fail SLP operation verification. The following does the latter. PR tree-optimization/116819 * tree-vect-stmts.cc (vect_analyze_stmt): When the SLP representative isn't relevant signal failure instead of success.

This adds a V16SI -> V4SI and related i.e. "quartering" vector-vector extract expander for VLS modes. It helps with spills in x264 that may cause a load-hit-store. gcc/ChangeLog: * config/riscv/autovec.md (vec_extract<mode><vls_quarter>): Add quarter vec-vec extract. * config/riscv/vector-iterators.md: New iterators.
