2025-07-24vect: remove cast to pointer for create_if in vect_create_data_ref_ptrAlfie Richards1-3/+2
Removes `fold_convert (aggr_ptr_type, iv_step)` when using create_iv. This was previously constructing statements like: ``` unsigned int _49; vector([4,4]) int * _50; sizetype _51; vector([4,4]) int * vectp_x.6; ... _50 = (vector([4,4]) int *) _49; _51 = (sizetype) _50; ... vectp_x.6_48 = vectp_x.6_47 + _51; ``` And instead creates: ``` unsigned int _49; sizetype _50; vector([4,4]) int * vectp_x.6; ... _50 = (sizetype) _49; ... vectp_x.6_48 = vectp_x.6_47 + _50; ``` As create_iv already has the logic to handle a pointer mode base and an integer mode var this seems a more natural expression of this. gcc/ChangeLog: * tree-vect-data-refs.cc (vect_create_data_ref_ptr): Remove unnecessary casts to aggr_ptr_type.

2025-07-23testsuite: Fix gcc.target/powerpc/vsx-builtin-7.c test [PR119382]Jeevitha1-1/+9
The test vsx-builtin-7.c failed on powerpc64le-linux due to Identical Code Folding (ICF) merging the functions insert_di_0_v2 and insert_di_0. This behavior was introduced by commit r15-7961-gdc47161c1f32c3, which enhanced alias analysis in ao_compare::compare_ao_refs, enabling the compiler to identify and optimize structurally identical functions. As a result, the compiler replaced insert_di_0_v2 with a tail call to insert_di_0, altering the expected test behavior. This patch adds -fno-ipa-icf to the test's dg-options to disable ICF, avoiding function merging and ensuring the test executes correctly. 2025-06-24 Jeevitha Palanisamy <jeevitha@linux.ibm.com> gcc/testsuite/ PR testsuite/119382 * gcc.target/powerpc/vsx-builtin-7.c: Add '-fno-ipa-icf' to dg-options.

2025-07-23RISC-V: Rework broadcast handling [PR121073].Robin Dapp17-250/+465
During the last weeks it became clear that our current broadcast handling needs an overhaul in order to improve maintainability. PR121073 showed that my intermediate fix wasn't enough and caused regressions. This patch now goes a first step towards untangling broadcast (vmv.v.x), "set first" (vmv.s.x), and zero-strided load (vlse). Also can_be_broadcast_p is rewritten and strided_broadcast_p is introduced to make the distinction clear directly in the predicates. Due to the pervasiveness of the patterns I needed to touch a lot of places and tried to clear up some things while at it. The patch therefore also introduces new helpers expand_broadcast for vmv.v.x that dispatches to regular as well as strided broadcast and expand_set_first that does the same thing for vmv.s.x. The non-strided fallbacks are now implemented as splitters of the strided variants. This makes it easier to see where and when things happen. The test cases I touched appeared wrong to me so this patch sets a new baseline for some of the scalar_move tests. There is still work to be done but IMHO that can be deferred: It would be clearer if the three broadcast-like variants differed not just in name but also in RTL pattern so matching is not as confusing. Right now vmv.v.x and vmv.s.x only differ in the mask and are interchangeable by just changing it from "all ones" to a "single one". As last time, I regtested on rv64 and rv32 with strided_broadcast turned on and off. Note there are regressions cond_fma_fnma-[78].c. Those are due to the patch exposing more fwprop/late-combine opportunities. For fma/fnma we don't yet have proper costing for vv/vx in place but I'll expect that to be addressed soon and figured we can live with those for the time being.

Here we're incorrectly rejecting the modules testcase (reduced from a std module example): $ cat 121179_a.C export module foo; enum class E { x }; bool operator==(E, int); export template<class T> void f() { E::x != 0; } $ cat 121179_b.C import foo; template void f<int>(); $ g++ -fmodules 121179_*.C In module foo, imported at 121179_b.C:1: 121179_a.C: In instantiation of ‘void f@foo() [with T = int]’: 121179_b.C:3:9: required from here 121179_a.C:9:8: error: no match for ‘operator!=’ (operand types are ‘E@foo’ and ‘int’) This is ultimately because our non-dependent rewritten operator expression handling throws away the result of unqualified lookup at template parse time, and so we have to repeat the lookup at instantiation time which fails because the operator== isn't exported. This is a known deficiency, but it's easy enough to narrowly fix this for simple != to == rewrites by making build_min_non_dep_op_overload look through logical negation.

2025-07-23Default to -mcpu=ultrasparc3 on Solaris/SPARCRainer Orth1-3/+2
Prompted by the discussions around a recent clang bug, I realized that gcc still defaults to -mcpu=v9 on Solaris/SPARC. This is an oversight since the Oracle Studio 12.6 cc, released in 2017, already defaults to -xarch=sparcvis2, the equivalent of -mcpu=ultrasparc3. Besides, both the 32 and 64-bit libc.so.1 require UltraSPARC III extensions anyway: SPARC32PLUS Version 1, V8+ Required, UltraSPARC3 Extensions Required [VIS] SPARCV9 Version 1, UltraSPARC3 Extensions Required [VIS] So this patch follows suite. Bootstrapped on sparc-sun-solaris2.11 and sparcv9-sun-solaris2.11 with as/ld, gas/ld, and gas/gld configurations. There are currently two regressions exposed by this patch (PRs 121191 and 121192), which are only present in gcc 16 resp. 15/16. There's one small caveat: while Solaris now marks all objects with EF_SPARC_32PLUS EF_SPARC_SUN_US1 EF_SPARC_SUN_US3, gas only sets the EF_SPARC_SUN_US[13] flags in the ELF header if UltraSPARC I/III insns are actually used. This is in accordance with the SPARC Compliance Definition 2.4.1, 4P-1. In the end, it doesn't matter anyway since libc.so.1 already has both flags, so the resulting executables and shared objects will too, anyway. 2025-07-20 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gcc: * config.gcc <sparc*-*-solaris2*> (with_cpu): Default to ultrasparc3.

2025-07-22c++: constexpr union placement new [PR121068]Jason Merrill3-3/+35
The note and example in [class.union] p6 think that placement new can be used to change the active member of a union, but we didn't support that for array members in constant-evaluation even after implementing P1330 and P2747. First I tried to address this by introducing a CLOBBER_BEGIN_OBJECT for the entire array, but that broke the resolution of LWG3436, which invokes 'new T[1]' for an array T, and trying to clobber a multidimensional array when the actual object is single-dimensional breaks. So I've raised that issue with the committee. Until that is resolved, this patch takes a simpler approach: allow initialization of an element of an array to make the array the active member of a union.

2025-07-22Change __builtin_unreachable to __builtin_trap (or infinite loop) if only ↵Andrew Pinski5-1/+68
thing in function [PR109267] When we have an empty function, things can go wrong with cfi_startproc/cfi_endproc and a few other things like exceptions. So if the only thing the function does is a call to __builtin_unreachable, let's replace that with a __builtin_trap instead if the target has a trap instruction. For targets without a trap instruction defined, replace it with an infinite loop; this allows not to need for the abort call to happen but still get the correct behavior of not having two functions at the same location. The QOI idea for basic block reorder is recorded as PR 120004.

2025-07-22xtensa: Make relaxed MOVI instructions treated as "load" typeTakayuki 'January June' Suwa1-3/+3
The relaxed MOVI instructions in the Xtensa ISA are assignment ones that contain large integer, floating-point or symbolic constants that would not normally be allowed as immediate values by instructions in assembly code, and will instead be translated by the assembler later rather the compiler, into the L32R instructions referencing to literal pool entries containing that values (see '-mauto-litpools' Xtensa-specific option). This means that even though such instructions look like nothing more than constant value assignments in their RTL representation, these may perform better by treating them as loads from memory (i.e. the actual behavior) and also trying to avoid using the value immediately after the load, especially from an instruction scheduling perspective. gcc/ChangeLog: * config/xtensa/xtensa.md (movsi_internal, movhi_internal, movsf_internal): Change the value of the "type" attribute from "move" to "load" when the source operand constraint is "Y".
2025-07-22middle-end: Enable masked load with non-constant offsetKarl Meakin2-17/+13
The function `vect_check_gather_scatter` requires the `base` of the load to be loop-invariant and the `off`set to be not loop-invariant. When faced with a scenario where `base` is not loop-invariant, instead of giving up immediately we can try swapping the `base` and `off`, if `off` is actually loop-invariant. Previously, it would only swap if `off` was the constant zero (and so trivially loop-invariant). This is too conservative: we can still perform the swap if `off` is a more complex but still loop-invariant expression, such as a variable defined outside of the loop. This allows loops like the function below to be vectorised, if the target has masked loads and sufficiently large vector registers (eg `-march=armv8-a+sve -msve-vector-bits=128`): ```c typedef struct Array { int elems[3]; } Array; int loop(Array **pp, int len, int idx) { int nRet = 0; for (int i = 0; i < len; i++) { Array *p = pp[i]; if (p) { nRet += p->elems[idx]; } } return nRet; } ``` gcc/ChangeLog: * tree-vect-data-refs.cc (vect_check_gather_scatter): Swap `base` and `off` in more scenarios.

So while debugging Austin's work to support the spacemit x60 in the BPI we found that even though his pipeline description had mappings for all the vector instructions, they were still getting matched by the generic-vector-ooo DFA. The core problem is that DFA never restricted itself to a tune option (oops). That's easily fixed, at which time everything using generic blows up because we don't have a generic in-order vector DFA. Everything using generic was indirectly also using generic-vector-ooo for the vector instructions. It may be better long term to define a generic-vector DFA, but to preserve behavior, I'm letting generic-vector-ooo match when the generic DFA is active. Tested in my tester, waiting on pre-commit CI before moving forward. gcc/ * config/riscv/generic-vector-ooo.md: Restrict insn reservations to generic_ooo and generic tuning models.
