2022-11-02c++: friend contracts are in complete-class contextJason Merrill9-44/+64
Comparing friend contracts to a previous declaration was awkward because at the point of duplicate_decls we haven't parsed the new ones yet, and we're about to throw away one of the decls. But conveniently, there's already defer_guarded_contract_match to handle this. This reverts commit 9c0d8bfebc32d5e2c35ed61753440fb175a87dcf. gcc/cp/ChangeLog: * contracts.cc (check_for_mismatched_contracts): Only check new_contract for deferred.

2022-10-31libstdc++-v3: <complex> support for extended floating point typesJakub Jelinek4-2/+955
The following patch adds <complex> support for extended floating point types. C++23 removes the float/double/long double specializations from the spec and instead adds explicit(bool) specifier on the converting constructor. The patch uses that for converting constructor of the base template as well as the float/double/long double specializations's converting constructors (e.g. so that it handles convertion construction also from complex of extended floating point types). Copy ctor was already defaulted as the spec now requires. The patch also adds partial specialization for the _Float{16,32,64,128} and __gnu_cxx::__bfloat16_t types because the base template doesn't use __complex__ but a pair of floating point values. The g++.dg/cpp23/ testcase verifies explicit(bool) works correctly. 2022-10-31 Jakub Jelinek <jakub@redhat.com> gcc/testsuite/ * g++.dg/cpp23/ext-floating12.C: New test. libstdc++-v3/ * include/std/complex (complex::complex converting ctor): For C++23 use explicit specifier with constant expression.

2022-10-31btf: Add support to BTF_KIND_ENUM64 typeGuillermo E. Martinez7-18/+100
BTF supports 64-bits enumerators with following encoding: struct btf_type: name_off: 0 or offset to a valid C identifier info.kind_flag: 0 for unsigned, 1 for signed info.kind: BTF_KIND_ENUM64 info.vlen: number of enum values size: 1/2/4/8 The btf_type is followed by info.vlen number of: struct btf_enum64 { uint32_t name_off; /* Offset in string section of enumerator name. */ uint32_t val_lo32; /* lower 32-bit value for a 64-bit value Enumerator */ uint32_t val_hi32; /* high 32-bit value for a 64-bit value Enumerator */ }; So, a new btf_enum64 structure was added to represent BTF_KIND_ENUM64 and a new field dtd_enum_unsigned in ctf_dtdef structure to distinguish when CTF enum is a signed or unsigned type, later that information is used to encode the BTF enum type. gcc/ChangeLog: * btfout.cc (btf_calc_num_vbytes): Compute enumeration size depending of enumerator type btf_enum{,64}. (btf_asm_type): Update btf_kflag according to enumeration type sign using dtd_enum_unsigned field for both: BTF_KIND_ENUM{,64}. (btf_asm_enum_const): New argument to represent the size of the BTF enum type, writing the enumerator constant value for 32 bits, if it's 64 bits then explicitly writes lower 32-bits value and higher 32-bits value. (output_asm_btf_enum_list): Add enumeration size argument. * ctfc.cc (ctf_add_enum): New argument to represent CTF enum basic information.

2022-10-31amdgcn: multi-size vector reductionsAndrew Stubbs3-94/+45
Add support for vector reductions for any vector width by switching iterators and generalising the code slightly. There's no one-instruction way to move an item from lane 31 to lane 0 (63, 15, 7, 3, and 1 are all fine though), and vec_extract is probably fewer cycles anyway, so now we always reduce to an SGPR. gcc/ChangeLog: * config/gcn/gcn-valu.md (V64_SI): Delete iterator.

2022-10-31builtins: Add __builtin_nextafterf16b builtinJakub Jelinek3-0/+4
The following patch adds another needed builtin. The earlier patch adds among other things __builtin_nextafterf16 builtin which we need in order to constexpr evaluate std::nextafter(_Float16) overload (patch for that has been posted already). While there is inline implementation of the overload, it isn't constant evaluation friendly, and the builtin doesn't need libm implementation because it will be used only during constant expression evaluation. We need the same thing also for std::nextafter(__gnu_cxx::__bfloat16_t) though and this patch does that. 2022-10-31 Jakub Jelinek <jakub@redhat.com> * builtin-types.def (BT_FN_BFLOAT16_BFLOAT16_BFLOAT16): New. * builtins.def (BUILT_IN_NEXTAFTERF16B): New builtin. * fold-const-call.cc (fold_const_call_sss): Handle CFN_BUILT_IN_NEXTAFTERF16B.
2022-10-31builtins: Add various __builtin_*f{16,32,64,128,32x,64x,128x} builtinsJakub Jelinek7-52/+531
When working on libstdc++ extended float support in <cmath>, I found that we need various builtins for the _Float{16,32,64,128,32x,64x,128x} types. Glibc 2.26 and later provides the underlying libm routines (except for _Float16 and _Float128x for the time being) and in libstdc++ I think we need at least the _Float128 builtins on x86_64, i?86, powerpc64le and ia64 (when long double is IEEE quad, we can handle it by using __builtin_*l instead), because without the builtins the overloads couldn't be constexpr (say when it would declare the *f128 extern "C" routines itself and call them). The testcase covers just types of those builtins and their constant folding, so doesn't need actual libm support. 2022-10-31 Jakub Jelinek <jakub@redhat.com> * builtin-types.def (BT_FLOAT16_PTR, BT_FLOAT32_PTR, BT_FLOAT64_PTR, BT_FLOAT128_PTR, BT_FLOAT32X_PTR, BT_FLOAT64X_PTR, BT_FLOAT128X_PTR): New DEF_PRIMITIVE_TYPE.

2022-10-29Restore RTL alias analysis for hard frame pointerEric Botcazou1-7/+12
The change: 2021-07-28 Bin Cheng <bin.cheng@linux.alibaba.com> alias.c (init_alias_analysis): Don't skip prologue/epilogue. broke the alias analysis for the hard frame pointer (when it is used as a frame pointer, i.e. when the frame pointer is not eliminated) described in the large comment at the top of the file, because static_reg_base_value is set for it and, consequently, new_reg_base_value too. When the instruction saving the stack pointer into the hard frame pointer in the prologue is processed, it is viewed as a second set of the hard frame pointer and to a different value by record_set, which then proceeds to reset new_reg_base_value to 0 and the game is over. gcc/ * alias.cc (init_alias_analysis): Do not record sets to the hard frame pointer if the frame pointer has not been eliminated.
2022-10-29d: Merge upstream dmd, druntime e4f8919591, phobos 3ad507b51.Iain Buclaw380-1983/+3826
D front-end changes: - Import dmd v2.101.0-beta.1. - Add predefined version `D_Optimized' when compiling with `-O'. - Shortened method syntax (DIP1043) is now enabled by default. - Array literals assigned to `scope' array variables are now allocated on the stack. - Implement `@system' variables (DIP1035), available behind the preview feature flag `-fpreview=systemvariables'. D runtime changes: - Import druntime v2.101.0-beta.1. Phobos changes: - Import phobos v2.101.0-beta.1. - Added `std.typecons.SafeRefCounted', that can be used in `@safe' code with `-fpreview=dip1000'. gcc/d/ChangeLog: * d-attribs.cc (apply_user_attributes): Update for new front-end interface. * d-builtins.cc (d_init_versions): Predefine `D_Optimized' with compiling with optimizations enabled. * d-lang.cc (d_handle_option): Update for new front-end interface.

2022-10-29d: Remove D-specific version definitions from target headersIain Buclaw20-95/+345
This splits up the targetdm sources so that each file only handles one target platform.
