9 hoursifconv: simple factor out operators while doing ifcvt [PR119920]Andrew Pinski4-0/+362
For possible reductions, ifconv currently handles if the addition is on one side of the if. But in the case of PR 119920, the reduction addition is on both sides of the if. E.g. ``` if (_27 == 0) goto <bb 14>; [50.00%] else goto <bb 13>; [50.00%] <bb 14> a_29 = b_14(D) + a_17; goto <bb 15>; [100.00%] <bb 13> a_28 = c_12(D) + a_17; <bb 15> # a_30 = PHI <a_28(13), a_29(14)> ``` Which ifcvt converts into: ``` _34 = _32 + _33; a_15 = (int) _34; _23 = _4 == 0; _37 = _33 + _35; a_13 = (int) _37; a_5 = _23 ? a_15 : a_13; ``` But the vectorizer does not recognize this as a reduction. To fix this, we should factor out the addition from the `if`. This allows us to get: ``` iftmp.0_7 = _22 ? b_13(D) : c_12(D); a_14 = iftmp.0_7 + a_18; ``` Which then the vectorizer recognizes as a reduction. In the case of PR 112324 and PR 110015, it is similar but with MAX_EXPR reduction instead of an addition. Note while this should be done in phiopt, there are regressions due to other passes not able to handle the factored out cases (see linked bug to PR 64700). I have not had time to fix all of the passes that could handle the addition being in the if/then/else rather than being outside yet. So this is I thought it would be useful just to have a localized version in ifconv which is then only used for the vectorizer. Bootstrapped and tested on x86_64-linux-gnu.

9 hoursifconv: Remove unused array predicatedAndrew Pinski1-4/+1
While starting to improve if-conv, I noticed that predicated was only being set once inside a loop and accessed right below. This became this way due to r14-8869-g8636c538b68068 and before it was needed since it was accessed via 2 loops but now it is only set and then accessed in the next statement, there is no reason for it being there.

17 hoursaarch64: Use SVE2 BSL2N for vector EONKyrylo Tkachov2-0/+86
SVE2 BSL2N (x, y, z) = (x & z) | (~y & ~z). When x == y this computes: (x & z) | (~x & ~z) which is ~(x ^ z). Thus, we can use it to match RTL patterns (not (xor (...) (...))) for both Advanced SIMD and SVE modes when TARGET_SVE2. This patch does that. For code like: uint64x2_t eon_q(uint64x2_t a, uint64x2_t b) { return EON(a, b); } svuint64_t eon_z(svuint64_t a, svuint64_t b) { return EON(a, b); } We now generate: eon_q: bsl2n z0.d, z0.d, z0.d, z1.d ret eon_z: bsl2n z0.d, z0.d, z0.d, z1.d ret instead of the previous: eon_q: eor v0.16b, v0.16b, v1.16b not v0.16b, v0.16b ret eon_z: eor z0.d, z0.d, z1.d ptrue p3.b, all not z0.d, p3/m, z0.d ret Bootstrapped and tested on aarch64-none-linux-gnu.

17 hoursaarch64: Use SVE2 NBSL for vector NOR and NAND for Advanced SIMD modesKyrylo Tkachov2-0/+97
We already have patterns to use the NBSL instruction to implement vector NOR and NAND operations for SVE types and modes. It is straightforward to have similar patterns for the fixed-width Advanced SIMD modes as well, though it requires combine patterns without the predicate operand and an explicit 'Z' output modifier. This patch does so. So now for example we generate for: uint64x2_t nand_q(uint64x2_t a, uint64x2_t b) { return NAND(a, b); } uint64x2_t nor_q(uint64x2_t a, uint64x2_t b) { return NOR(a, b); } nand_q: nbsl z0.d, z0.d, z1.d, z1.d ret nor_q: nbsl z0.d, z0.d, z1.d, z0.d ret instead of the previous: nand_q: and v0.16b, v0.16b, v1.16b not v0.16b, v0.16b ret nor_q: orr v0.16b, v0.16b, v1.16b not v0.16b, v0.16b ret The tied operand requirements for NBSL mean that we can generate the MOVPRFX when the operands fall that way, but I guess having a 2-insn MOVPRFX form is not worse than the current 2-insn codegen at least, and the MOVPRFX can be fused by many cores.

22 hoursi386: Decouple AMX-AVX512 from AVX10.2 and imply AVX512FHaochen Jiang5-11/+10
In ISE058, the AVX10.2 imply is removed from AMX-AVX512. This leads to re-consideration on the imply for AMX-AVX512. Since it is using zmm register and using zmm register only, we need to at least imply AVX512F. AVX512VL is not needed. On the other hand, if we imply AVX10.1 for AMX-AVX512, it will cause -mno-avx10.1 disabling AMX-AVX512. This would be a surprise for users.

23 hoursRISC-V: Refine the scalar SAT_* test casesPan Li262-4101/+517
Per previous discuss with Jeff, we don't do complicated asm check like scalar saturation alu. It is somehow not easy to maintain, as well as fragile. Thus, we remove these function-body check, and introduce the jmp label asm check instead.The code-gen of SAT_* will never have a jmp, and the other run test will make sure the correctness of SAT_* code-gen. The below test suites are passed for this patch series. * The rv64gcv fully regression test. The below failed test cases are resolved: FAIL: gcc.target/riscv/sat/sat_s_add_imm-2-i8.c -Oz check-function-bodies sat_s_add_imm_int8_t_fmt_2_1 FAIL: gcc.target/riscv/sat/sat_s_add_imm-2-i8.c -Os

28 hourslibgdiagnostics: add diagnostic_message_buffer [PR120792]David Malcolm28-205/+1852
This patch extends libgdiagnostics to provide a way to capture the pp tokens making up a message string, so that SARIF and HTML sinks can retain information such as event IDs and URLs. As well as richer output, this improves the round-tripping of such information through sarif-replay.

29 hoursc++: don't mark void exprs as read [PR44677]Jason Merrill3-40/+15
In Jakub's patch for PR44677 he added code to prevent mark_exp_read on e.g. (void)++i from marking i as read, but it seems to me that we can generalize that to avoid looking any farther into any void expression; you can't read a void value, and an explicit cast will have already called mark_exp_read on its operand in convert_to_void. For testing I added an assert to catch places where we were trying to mark void expressions as read, and fix a few that it found. But there were several other places (such as check_return_expr) where we could have a void expression but always calling mark_exp_read makes sense, so I dropped the assert from the final commit.

33 hoursc++: constexpr uninitialized union [PR120577]Jason Merrill2-3/+48
This was failing for two reasons: 1) We were wrongly treating the basic_string constructor as zero-initializing the object, which it doesn't. 2) Given that, when we went to look for a value for the anonymous union, we concluded that it was value-initialized, and trying to evaluate that broke because we weren't setting ctx->ctor for it. This patch fixes both issues, #1 by setting CONSTRUCTOR_NO_CLEARING and #2 by inserting a new CONSTRUCTOR for the member rather than evaluate it out of context, which is consistent with cxx_eval_store_expression.

34 hoursasf: Fix offset check in base reg initialization for big-endian targetsKonstantinos Eleftheriou2-13/+28
During the base register initialization, in the case that we are eliminating the load instruction, we are using `offset == 0` in order to find the store instruction that has the same offset as the load. This would not work on big-endian targets where byte 0 would be the MS byte. This patch updates the condition to take into account the target's endianness. We are, also, removing the adjustment of the starting position for the bitfield insertion, when BYTES_BIG_ENDIAN != BITS_BIG_ENDIAN. This is supposed to be handled inside `store_bit_field` and it's not needed anymore after the offset fix. Bootstrapped/regtested on AArch64 LE, x86_64 and PowerPC LE. gcc/ChangeLog: * avoid-store-forwarding.cc (generate_bit_insert_sequence): Remove adjustment of bitfield insertion's starting position when BYTES_BIG_ENDIAN != BITS_BIG_ENDIAN.

This patch adds the ability to fold the address computation into the addressing mode for LDAPR instructions using LDAPUR when RCPC2 is available. LDAPUR emission is enabled by default when RCPC2 is available, but can be disabled using the avoid_ldapur tune flag on a per-core basis. Currently, it is disabled for neoverse-v2, neoverse-v3, cortex-x925, and architecutres before armv8.8-a.

35 hoursc, c++: Extend -Wunused-but-set-* warnings [PR44677]Jakub Jelinek40-57/+1185
The -Wunused-but-set-* warnings work by using 2 bits on VAR_DECLs & PARM_DECLs, TREE_USED and DECL_READ_P. If neither is set, we typically emit -Wunused-variable or -Wunused-parameter warning, that is for variables which are just declared (including initializer) and completely unused. If TREE_USED is set and DECL_READ_P is unset, -Wunused-but-set-* warnings are emitted, i.e. for variables which can appear on the lhs of an assignment expression but aren't actually used elsewhere. The DECL_READ_P marking is done through mark_exp_read called from lots of places (e.g. lvalue to rvalue conversions etc.). LLVM has an extension on top of that in that it doesn't count pre/post inc/decrements as use (i.e. DECL_READ_P for GCC). The following patch does that too, though because we had the current behavior for 11+ years already and lot of people is -Wunused-but-set-* warning free in the current GCC behavior and not in the clang one (including GCC sources), it allows users to choose. Furthermore, it implements another level, where also var @= expr uses of var (except when it is also used in expr) aren't counted as DECL_READ_P. I think it would be nice to also handle var = var @ expr or var = expr @ var but unfortunately mark_exp_read is then done in both FEs during parsing of var @ expr or expr @ var and the code doesn't know it is rhs of an assignment with var as lhs. The patch works mostly by checking if DECL_READ_P is clear at some point and then clearing it again after some operation which might have set it. -Wunused or -Wall or -Wunused -Wextra or -Wall -Wextra turn on the 3 level of the new warning (i.e. the one which ignores also var++, ++var etc. as well as var @= expr), so does -Wunused-but-set-{variable,parameter}, but users can use explicit -Wunused-but-set-{variable,parameter}={1,2} to select a different level. 2025-07-15 Jakub Jelinek <jakub@redhat.com> Jason Merrill <jason@redhat.com> PR c/44677 gcc/ * common.opt (Wunused-but-set-parameter=, Wunused-but-set-variable=): New options.

40 hoursfortran: Amend descriptor bounds init if unallocatedMikael Morin2-47/+49
Always generate the conditional initialization of unallocated variables regardless of the basic variable allocation tracking done in the frontend and with an additional always false condition. The scalarizer used to always evaluate array bounds, including in the case of unallocated arrays on the left hand side of an assignment. This was (correctly) causing uninitialized warnings, even if the uninitialized values were in the end discarded. Since the fix for PR fortran/108889, an initialization of the descriptor bounds is added to silent the uninitialized warnings, conditional on the array being unallocated. This initialization is not useful in the execution of the program, and it is removed if the compiler can prove that the variable is unallocated (in the case of a local variable for example). Unfortunately, the compiler is not always able to prove it and the useless initialization may remain in the final code. Moreover, the generated code that was causing the evaluation of uninitialized variables has ben changed to avoid them, so we can try to remove or revisit that unallocated variable bounds initialization tweak. Unfortunately, just removing the extra initialization restores the warnings at -O0, as there is no dead code removal at that optimization level. Instead, this change keeps the initialization and modifies its guarding condition with an extra always false variable, so that if optimizations are enabled the whole initialization block is removed, and if they are disabled it remains and is sufficient to prevent the warning. The new variable requires the code generation to be done earlier in the function so that the variable declaration and usage are in the same scope. As the modified condition guarantees the removal of the block with optimizations, we can emit it more broadly and remove the basic allocation tracking that was done in the frontend to limit its emission. gcc/fortran/ChangeLog: * gfortran.h (gfc_symbol): Remove field allocated_in_scope. * trans-array.cc (gfc_array_allocate): Don't set it. (gfc_alloc_allocatable_for_assignment): Likewise. Generate the unallocated descriptor bounds initialisation before the opening of the reallocation code block. Create a variable and use it as additional condition to the unallocated descriptor bounds initialisation.
40 hoursfortran: Delay evaluation of array bounds after reallocationMikael Morin2-47/+104
Delay the evaluation of bounds, offset, etc after the reallocation, for the scalarization of allocatable arrays on the left hand side of assignments. Before this change, the code preceding the scalarization loop is like: D.4757 = ref2.offset; D.4759 = ref2.dim[0].ubound; D.4762 = ref2.dim[0].lbound; { if (ref2.data == 0B) goto realloc; if (ref2.dim[0].lbound + 4 != ref2.dim[0].ubound) goto realloc; goto L.10; realloc: ... change offset and bounds ... D.4757 = ref2.offset; D.4762 = NON_LVALUE_EXPR <ref2.dim[0].lbound>; ... reallocation ... L.10:; } while (1) { ... scalarized code ... so the bounds etc are evaluated first to variables, and the reallocation code takes care to update the variables during the reallocation. This is problematic because the variables' initialization references the array bounds, which for unallocated arrays are uninitialized at the evaluation point. This used to (correctly) cause uninitialized warnings (see PR fortran/108889), and a workaround for variables was found, that initializes the bounds of arrays variables to some value beforehand if they are unallocated. For allocatable components, there is no warning but the problem remains, some uninitialized values are used, even if discarded later. After this change the code becomes: { if (ref2.data == 0B) goto realloc; if (ref2.dim[0].lbound + 4 != ref2.dim[0].ubound) goto realloc; goto L.10; realloc:; ... change offset and bounds ... ... reallocation ... L.10:; } D.4762 = ref2.offset; D.4763 = ref2.dim[0].lbound; D.4764 = ref2.dim[0].ubound; while (1) { ... scalarized code so the scalarizer avoids storing the values to variables at the time it evaluates them, if the array is reallocatable on assignment. Instead, it keeps expressions with references to the array descriptor fields, expressions that remain valid through reallocation. After the reallocation code has been generated, the expressions stored by the scalarizer are evaluated in place to variables. The decision to delay evaluation is based on the existing field is_alloc_lhs, which requires a few tweaks to be alway correct wrt to what its name suggests. Namely it should be set even if the assignment right hand side is an intrinsic function, and it should not be set if the right hand side is a scalar and neither if the -fno-realloc-lhs flag is passed to the compiler. gcc/fortran/ChangeLog: * trans-array.cc (gfc_conv_ss_descriptor): Don't evaluate offset and data to a variable if is_alloc_lhs is set. Move the existing evaluation decision condition for data... (save_descriptor_data): ... here as a new predicate. (evaluate_bound): Add argument save_value.

(gfc_is_reallocatable_lhs): Return false if flag_realloc_lhs isn't set. (gfc_alloc_allocatable_for_assignment): Don't update the variables that may be stored in saved_offset, delta, and data. Call instead...

Clear the flag if the right hand side is scalar.
40 hoursfortran: Generate array reallocation out of loopsMikael Morin1-9/+12
Generate the array reallocation on assignment code before entering the scalarization loops. This doesn't move the generated code itself, which was already put before the outermost loop, but only changes the current scope at the time the code is generated. This is a prerequisite for a followup patch that makes the reallocation code create new variables. Without this change the new variables would be declared in the innermost loop body and couldn't be used outside of it. gcc/fortran/ChangeLog: * trans-expr.cc (gfc_trans_assignment_1): Generate array reallocation code before entering the scalarisation loops.
