Since Commit c608ada2 Author: Zac Walker <zacwalker@microsoft.com> CommitDate: 2024-01-23 15:32:30 +0000 Ifdef `.hidden`, `.type`, and `.size` pseudo-ops for `aarch64-w64-mingw32` target lse.S includes aarch64-asm.h, leading to a conflicting definition of macro 'L': - in lse.S it expands to either '' or 'L' - in aarch64-asm.h it is used to generate .L ## label lse.S does not use the second, so this patch just undefines L after the inclusion of aarch64-asm.h. libgcc/ * config/aarch64/lse.S: Undefine L() macro.

Don't bail out early if the offset to a pointer in __builtin_object_size is a variable, return the wholesize instead since that is a better fallback for maximum estimate.

This was added as part of the initial Concepts TS implementation and reflects an early version of the Concepts TS paper, which is very different from standard C++20 concepts (and even from more recent versions of the Concepts TS, support for which we deprecated in GCC 14 and removed for GCC 15). So there's not much to salvage from this section besides the __is_same trait documentation which we can conveniently move to the previous Type Traits section. gcc/ChangeLog: * doc/extend.texi (C++ Concepts): Remove section. Move __is_same documentation to the previous Type Traits section. Reviewed-by:Jason Merrill <jason@redhat.com>

The testcases shows single-element interleaving of size three being exempted from permutation lowering via heuristics (see also PR116973).

The following patch partially implements the N3353 paper. In particular, it adds support for the delimited escape sequences (\u{123}, \x{123}, \o{123}) which were added already for C++23, all I had to do is split the delimited escape sequence guarding from named universal character escape sequence guards (\N{LATIN CAPITAL LETTER C WITH CARON}), which C++23 has but C2Y doesn't and emit different diagnostics for C from C++ for the delimited escape sequences. And it adds support for the new style of octal literals, 0o137 or 0O1777. I have so far added that just for C and not C++, because I have no idea whether C++ will want to handle it similarly. What the patch doesn't do is any kind of diagnostics for obsoletion of \137 or 0137, as discussed in the PR, I think it is way too early for that.

Apparently my c: Speed up compilation of large char array initializers when not using #embed patch broke building glibc. The issue is that when using CPP_EMBED, we are guaranteed by the preprocessor that there is CPP_NUMBER CPP_COMMA before it and CPP_COMMA CPP_NUMBER after it (or CPP_COMMA CPP_EMBED), so RAW_DATA_CST never ends up at the end of arrays of unknown length. Now, the c_parser_initval optimization attempted to preserve that property rather than changing everything that e.g. inferes array number of elements from the initializer etc. to deal with RAW_DATA_CST at the end, but it didn't take into account the possibility that there could be CPP_COMMA followed by CPP_CLOSE_BRACE (where the CPP_COMMA is redundant). As we are peaking already at 4 tokens in that code, peeking more would require using raw tokens and that seems to be expensive doing it for every pair of tokens due to vec_free done when we are out of raw tokens. So, the following patch instead determines the case where we want another INTEGER_CST element after it after consuming the tokens, and just arranges for another process_init_element. 2024-10-17 Jakub Jelinek <jakub@redhat.com> PR c/117177 gcc/c/ * c-parser.cc (c_parser_initval): Instead of doing orig_len == INT_MAX checks before consuming tokens to set last = 1, check it after consuming it and if not followed by CPP_COMMA CPP_NUMBER, call process_init_element once more with the last CPP_NUMBER. gcc/testsuite/ * c-c++-common/init-4.c: New test.

This patch makes the non-predicated vdupq_n MVE intrinsics use vec_duplicate rather than an unspec. This enables the compiler to generate better code sequences (for instance using vmov when possible). The patch renames the existing mve_vdup<mode> pattern into @mve_vdupq_n<mode>, and removes the now useless @mve_<mve_insn>q_n_f<mode> and @mve_<mve_insn>q_n_<supf><mode> ones. As a side-effect, it needs to update the mve_unpredicated_insn predicates in @mve_<mve_insn>q_m_n_<supf><mode> and @mve_<mve_insn>q_m_n_f<mode>. Using vec_duplicates means the compiler is now able to use vmov in the tests with an immediate argument in vdupq_n_[su]{8,16,32}.c: vmov.i8 q0,#0x1 However, this is only possible when the immediate has a suitable value (MVE encoding constraints, see imm_for_neon_mov_operand predicate). Provided we adjust the cost computations in arm_rtx_costs_internal(), when the immediate does not meet the vmov constraints, we now generate: mov r0, #imm vdup.xx q0,r0 or ldr r0, .L4 vdup.32 q0,r0 in the f32 case (with 1.1 as immediate). Without the cost adjustment, we would generate: vldr.64 d0, .L4 vldr.64 d1, .L4+8 and an associated literal pool entry. Regarding the testsuite updates: -------------------------------- * The signed versions of vdupq_* tests lack a version with an immediate argument. This patch adds them, similar to what we already have for vdupq_n_u*.c tests. * Code generation for different immediate values is checked with the new tests this patch introduces. Note there's no need for s8/u8 tests because 8-bit immediates always comply wth imm_for_neon_mov_operand. * We can remove xfail from vcmp*f tests since we now generate: movw r3, #15462 vcmp.f16 eq, q0, r3 instead of the previous: vldr.64 d6, .L5 vldr.64 d7, .L5+8 vcmp.f16 eq, q0, q3 Tested on arm-linux-gnueabihf and arm-none-eabi with no regression. 2024-07-02 Jolen Li <jolen.li@arm.com> Christophe Lyon <christophe.lyon@arm.com> gcc/ * config/arm/arm-mve-builtins-base.cc (vdupq_impl): New class.

Now that C23 support is essentially feature-complete, I'd like to switch the default language version for C compilation to -std=gnu23. This requires updating a large number of testcases that fail with the new language version if left unchanged. In this patch, update most of the tests for which there is a safe change that works both before and after the update to default language version - typically adding the option -std=gnu17 or -Wno-old-style-definition to the tests. (There are also a few tests where I'd like to investigate further why they fail with -std=gnu23, or where I think such failures show an actual bug to fix before changing the default language version, or where it seems more appropriate to make a testcase change that would result in failures in the absence of the language version change rather than just adding an option that does nothing with the gnu17 default.) The libffi test fixes have also been submitted upstream: <https://github.com/libffi/libffi/pull/861>. Most of the failures requiring such changes are for one of two reasons: * Unprototyped function declarations with () (meaning the same as (void) in C23 mode) for a function then called with arguments. * Old-style function definitions, which warn by default in C23 mode, so resulting in test failures for the unexpected warnings. Other reasons for failures include: * Tests with their own definitions of bool, true and false. * Tests of diagnostics (often with -pedantic) in cases where C23 has changed semantics, such as: - tag compatibility for structs; - enum values out of range of int; - handing of qualified array types; - decimal floating types formerly needing -pedantic diagnostics, but being standard in C23.

Jonathan mentioned an unnamed static analyzer reported issue in c_finish_bc_name. It is actually a false positive, because the construction of the loop_names vector guarantees that the last element of the vector (if the vector is non-empty) always has either C_DECL_LOOP_NAME (l) or C_DECL_SWITCH_NAME (l) (or both) flags set, so c will be always non-NULL after the if at the start of the loops. The following patch is an attempt to help those static analyzers (though dunno if it actually helps), by adding a checking assert. 2024-10-16 Jakub Jelinek <jakub@redhat.com> * c-decl.cc (c_get_loop_names): Add checking assert that c is non-NULL in the loop. (c_finish_bc_name): Likewise.

Jonathan pointed me at a diagnostic from an unnamed static analyzer which found that next.original_type isn't initialized for the CPP_EMBED case when it is parsed in a comma expression, yet expr.original_type = next.original_type; is done a few lines later and the expr is returned. 2024-10-16 Jakub Jelinek <jakub@redhat.com> * c-parser.cc (c_parser_expression): Initialize next.original_type to integer_type_node for the CPP_EMBED case.

Kind of undoes r15-4315-g9f549d216c9716 by adding the original testcase back; namely, adding acc_on_device-1-3.f as acc_on_device-1-4.f with -fno-builtin-acc_on_device removed. libgomp/ChangeLog: * testsuite/libgomp.oacc-fortran/acc_on_device-1-4.f: New test; same as acc_on_device-1-3.f but using the builtin function.

While working on PR117028 C2Y changes, I've noticed weird ternary operator formatting (operand1 ? operand2: operand3). The usual formatting is operand1 ? operand2 : operand3 where we have around 18000+ cases of that (counting only what fits on one line) and indent -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2 -ndj \ -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -psl -nsc -nsob documented in https://www.gnu.org/prep/standards/html_node/Formatting.html#Formatting does the same. Some code was even trying to save space as much as possible and used operand1?operand2:operand3 or operand1 ? operand2:operand3 Today I've grepped for such cases (the grep was '?.*[^ ]:' and I had to skim through various false positives with that where the : matched e.g. stuff inside of strings, or *.md pattern macros or :: scope) and the following patch is a fix for what I found. 2024-10-16 Jakub Jelinek <jakub@redhat.com> gcc/ * attribs.cc (lookup_scoped_attribute_spec): ?: operator formatting fixes. * basic-block.h (FOR_BB_INSNS_SAFE): Likewise. * cfgcleanup.cc (outgoing_edges_match): Likewise. * cgraph.cc (cgraph_node::dump): Likewise. * config/arc/arc.cc (gen_acc1, gen_acc2): Likewise. * config/arc/arc.h (CLASS_MAX_NREGS, CONSTANT_ADDRESS_P): Likewise. * config/arm/arm.cc (arm_print_operand): Likewise. * config/cris/cris.md (*b<rnzcond:code><mode>): Likewise. * config/darwin.cc (darwin_asm_declare_object_name, darwin_emit_common): Likewise. * config/darwin-driver.cc (darwin_driver_init): Likewise. * config/epiphany/epiphany.md (call, sibcall, call_value, sibcall_value): Likewise. * config/i386/i386.cc (gen_push2): Likewise. * config/i386/i386.h (ix86_cur_cost): Likewise. * config/i386/openbsdelf.h (FUNCTION_PROFILER): Likewise. * config/loongarch/loongarch-c.cc (loongarch_cpu_cpp_builtins): Likewise. * config/loongarch/loongarch-cpu.cc (fill_native_cpu_config): Likewise. * config/riscv/riscv.cc (riscv_union_memmodels): Likewise. * config/riscv/zc.md (*mva01s<X:mode>, *mvsa01<X:mode>): Likewise. * config/rs6000/mmintrin.h (_mm_cmpeq_pi8, _mm_cmpgt_pi8, _mm_cmpeq_pi16, _mm_cmpgt_pi16, _mm_cmpeq_pi32, _mm_cmpgt_pi32): Likewise. * config/v850/predicates.md (pattern_is_ok_for_prologue): Likewise. * config/xtensa/constraints.md (d, C, W): Likewise. * coverage.cc (coverage_begin_function, build_init_ctor, build_gcov_exit_decl): Likewise. * df-problems.cc (df_create_unused_note): Likewise. * diagnostic.cc (diagnostic_set_caret_max_width): Likewise. * diagnostic-path.cc (path_summary::path_summary): Likewise. * expr.cc (expand_expr_divmod): Likewise. * gcov.cc (format_gcov): Likewise. * gcov-dump.cc (dump_gcov_file): Likewise. * genmatch.cc (main): Likewise. * incpath.cc (remove_duplicates, register_include_chains): Likewise. * ipa-devirt.cc (dump_odr_type): Likewise. * ipa-icf.cc (sem_item_optimizer::merge_classes): Likewise. * ipa-inline.cc (inline_small_functions): Likewise. * ipa-polymorphic-call.cc (ipa_polymorphic_call_context::dump): Likewise. * ipa-sra.cc (create_parameter_descriptors): Likewise. * ipa-utils.cc (find_always_executed_bbs): Likewise. * predict.cc (predict_loops): Likewise. * selftest.cc (read_file): Likewise. * sreal.h (SREAL_SIGN, SREAL_ABS): Likewise. * tree-dump.cc (dequeue_and_dump): Likewise. * tree-ssa-ccp.cc (bit_value_binop): Likewise. gcc/c-family/ * c-opts.cc (c_common_init_options, c_common_handle_option, c_common_finish, set_std_c89, set_std_c99, set_std_c11, set_std_c17, set_std_c23, set_std_cxx98, set_std_cxx11, set_std_cxx14, set_std_cxx17, set_std_cxx20, set_std_cxx23, set_std_cxx26): ?: operator formatting fixes. gcc/cp/ * search.cc (lookup_member): ?: operator formatting fixes. * typeck.cc (cp_build_modify_expr): Likewise. libcpp/ * expr.cc (interpret_float_suffix): ?: operator formatting fixes. -

With SLP forced we fail to use gather for PR65518 on RISC-V as expected because we're failing due to not effective peeling for gaps. The following appropriately moves the memory_access_type adjustment before doing all the overrun checking since using VMAT_ELEMENTWISE means there's no overrun. * tree-vect-stmts.cc (get_group_load_store_type): Move VMAT_ELEMENTWISE fallback for single-element interleaving of too large groups before overrun checking. * gcc.dg/vect/pr65518.c: Adjust.

The following prepares us for SLP instances with a non-uniform number of lanes. We already have this with load permutation lowering, but we managed to keep that within the constraints of the per SLP instance computed VF based on its max_nunits (with a vector type fixed for each node) and the instance group size which is the number of lanes in the SLP instance root. But in the case where arbitrary splitting and merging SLP nodes at non-power-of-two lane boundaries is allowed this simple calculation based on the outgoing group size falls apart. The following, instead of computing a VF during SLP instance discovery, computes it at vect_make_slp_decision time by walking the SLP graph and looking at each SLP node in isolation. We do track max_nunits per node which could be a VF per node instead or forgo with both completely (though for BB vectorization we need to communicate a VF > 1 requirement upward, or compute that after the fact). In the end we'd like to delay vector type assignment and only compute a minimum VF here, allowing vector types to grow when the actual VF is bigger. There's slight complication with permutes of externs / constants as those get their vector type (and thus max_nunits) assigned late. While we force them to have the same vector type as the result at the moment their number of lanes can differ. So those get handled explicitly there right now to up the VF as needed - the alternative is to fail vectorization, I have an addition to vect_maybe_update_slp_op_vectype that would FAIL if the set vector type isn't within the constraints of the VF. * tree-vectorizer.h (SLP_INSTANCE_UNROLLING_FACTOR): Remove.

In compute_nregs_for_mode we expect that the current variable's mode is at most as large as the biggest mode to be used for vectorization. This might not be true for constants as they don't actually have a mode. In that case, just use the biggest mode so max_number_of_live_regs returns 1. This fixes several test cases in the test suite. gcc/ChangeLog: PR target/116655 * config/riscv/riscv-vector-costs.cc (max_number_of_live_regs): Use biggest mode instead of constant's saved mode. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/pr116655.c: New test.
