Fixes for commit r14-2792-g25072a477a56a727b369bf9b20f4d18198ff5894 "OpenMP: Call cuMemcpy2D/cuMemcpy3D for nvptx for omp_target_memcpy_rect", namely: In that commit, the code was changed to handle shared-memory devices; however, as pointed out, omp_target_memcpy_check already set the pointer to NULL in that case. Hence, this commit reverts to the prior version. In cuda.h, it adds cuMemcpyPeer{,Async} for symmetry for cuMemcpy3DPeer (all currently unused) and in three structs, fixes reserved-member names and remove a bogus 'const' in three structs. And it changes a DLSYM to DLSYM_OPT as not all plugins support the new functions, yet. include/ChangeLog: * cuda/cuda.h (CUDA_MEMCPY2D, CUDA_MEMCPY3D, CUDA_MEMCPY3D_PEER): Remove bogus 'const' from 'const void *dst' and fix reserved-name name in those structs. (cuMemcpyPeer, cuMemcpyPeerAsync): Add. libgomp/ChangeLog: * target.c (omp_target_memcpy_rect_worker): Undo dim=1 change for GOMP_OFFLOAD_CAP_SHARED_MEM. (omp_target_memcpy_rect_copy): Likewise for lock condition. (gomp_load_plugin_for_device): Use DLSYM_OPT not DLSYM for memcpy3d/memcpy2d. * plugin/plugin-nvptx.c (GOMP_OFFLOAD_memcpy2d, GOMP_OFFLOAD_memcpy3d): Use memset 0 to nullify reserved and unused src/dst fields for that mem type; remove '{src,dst}LOD = 0'.

When copying a 2D or 3D rectangular memmory block, the performance is better when using CUDA's cuMemcpy2D/cuMemcpy3D instead of copying the data one by one. That's what this commit does. Additionally, it permits device-to-device copies, if neccessary using a temporary variable on the host. include/ChangeLog: * cuda/cuda.h (CUlimit): Add CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_INVALID_HANDLE.

Reduce number of enum values passed to libgomp as GOMP_MAP_PRESENT_{TO,TOFROM,FROM,ALLOC} have the same semantic as GOMP_MAP_FORCE_PRESENT (i.e. abort if not present, otherwise ignore); that's different to GOMP_MAP_ALWAYS_PRESENT_{TO,TOFROM,FROM} which also abort if not present but copy data when present. This is is a follow-up to the commit r14-1579-g4ede915d5dde93 done 6 days ago.

This implements support for the OpenMP 5.1 'present' modifier, which can be used in map clauses in the 'target', 'target data', 'target data enter' and 'target data exit' constructs, and in the 'to' and 'from' clauses of the 'target update' construct. It is also supported in defaultmap. The modifier triggers a fatal runtime error if the data specified by the clause is not already present on the target device.

This is one part of the fix for PR109128, along with a corresponding binutils's linker change. Without this patch, what happens in the linker, when an unused object in a .a file has offload data, is that elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p, which ends up calling the plugin's claim_file_handler, which then records the object as one with offload data. That is, the linker never decides to use the object in the first place, but use of this _p interface (called as part of trying to decide whether to use the object) results in the plugin deciding to use its offload data (and a consequent mismatch in the offload data present at runtime). The new hook allows the linker plugin to distinguish calls to claim_file_handler that know the object is being used by the linker (from ldmain.c:add_archive_element), from calls that don't know it's being used by the linker (from elf_link_is_defined_archive_symbol); in the latter case, the plugin should avoid recording the object as one with offload data.

Switch from using stacks in the "private segment" to using a memory block allocated on the host side. The primary reason is to permit the reverse offload implementation to access values located on the device stack, but there may also be performance benefits, especially with repeated kernel invocations. This implementation unifies the stacks with the "team arena" optimization feature, and now allows both to have run-time configurable sizes. A new ABI is needed, so all libraries must be rebuilt, and newlib must be version 4.3.0.20230120 or newer. gcc/ChangeLog: * config/gcn/gcn-run.cc: Include libgomp-gcn.h.

If the DECL_VALUE_EXPR of a VAR_DECL has EXPR_LOCATION set, then any use of that variable looks like it has that location, which leads to the debugger jumping back and forth for both lambdas and structured bindings. Rather than fix all the uses, it seems simplest to remove any EXPR_LOCATION when setting DECL_VALUE_EXPR. So the cp/ hunks aren't necessary, but they avoid the need to unshare to remove the location.

Templated lambdas have a template-head, which is part of their signature. GCC ABI 18 mangles that into the lambda name. This adds support to the demangler. We have to introduce artificial template parameter names, as we need to refer to them from later components of the lambda signature. We use $T:n, $N:n and $TT:n for type, non-type and template parameters. Non-type parameter names are not shown in the strictly correct location -- for instance 'int (&NT) ()' would be shown as 'int (&) $N:n'. That's unfortunate, but an orthogonal issue. The 'is_lambda_arg' field is now repurposed as indicating the number of explicit template parameters (1-based). include/ * demangle.h (enum demangle_component_type): Add DEMANGLE_COMPONENT_TEMPLATE_HEAD, DEMANGLE_COMPONENT_TEMPLATE_TYPE_PARM, DEMANGLE_COMPONENT_TEMPLATE_NON_TYPE_PARM, DEMANGLE_COMPONENT_TEMPLATE_TEMPLATE_PARM, DEMANGLE_COMPONENT_TEMPLATE_PACK_PARM. libiberty/ * cp-demangle.c (struct d_print_info): Rename is_lambda_arg to lambda_tpl_parms.

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. (ctf_add_generic): Use of ei_{name. size, unsigned} to build the dtd structure containing enumeration information. (ctf_add_enumerator): Update comment mention support for BTF enumeration in 64-bits. * dwarf2ctf.cc (gen_ctf_enumeration_type): Extract signedness for enumeration type and use it in ctf_add_enum. * ctfc.h (ctf_dmdef): Update dmd_value to HOST_WIDE_INT to allow use 32/64 bits enumerators. information. (ctf_dtdef): New field to describe enum signedness. include/ * btf.h (btf_enum64): Add new definition and new symbolic constant to BTF_KIND_ENUM64 and BTF_KF_ENUM_{UN,}SIGNED. gcc/testsuite/ChangeLog: * gcc.dg/debug/btf/btf-enum-1.c: Update testcase, with correct info.kflags encoding. * gcc.dg/debug/btf/btf-enum64-1.c: New testcase.

This patch adds a stub 'gomp_target_rev' in the host's target.c, which will later handle the reverse offload. For nvptx, it adds support for forwarding the offload gomp_target_ext call to the host by setting values in a struct on the device and querying it on the host - invoking gomp_target_rev on the result. include/ChangeLog: * cuda/cuda.h (enum CUdevice_attribute): Add CU_DEVICE_ATTRIBUTE_UNIFIED_ADDRESSING. (CU_MEMHOSTALLOC_DEVICEMAP): Define. (cuMemHostAlloc): Add prototype. libgomp/ChangeLog: * config/nvptx/icv-device.c (GOMP_DEVICE_NUM_VAR): Remove 'static' for this variable. * config/nvptx/libgomp-nvptx.h: New file. * config/nvptx/target.c: Include it. (GOMP_ADDITIONAL_ICVS): Declare extern var. (GOMP_REV_OFFLOAD_VAR): Declare var. (GOMP_target_ext): Handle reverse offload. * libgomp-plugin.h (GOMP_PLUGIN_target_rev): New prototype. * libgomp-plugin.c (GOMP_PLUGIN_target_rev): New, call ... * target.c (gomp_target_rev): ... this new stub function. * libgomp.h (gomp_target_rev): Declare. * libgomp.map (GOMP_PLUGIN_1.4): New; add GOMP_PLUGIN_target_rev. * plugin/cuda-lib.def (cuMemHostAlloc): Add. * plugin/plugin-nvptx.c: Include libgomp-nvptx.h. (struct ptx_device): Add rev_data member. (nvptx_open_device): Remove async_engines query, last used in r10-304-g1f4c5b9b; add unified-address assert check. (GOMP_OFFLOAD_get_num_devices): Claim unified address support. (GOMP_OFFLOAD_load_image): Free rev_fn_table if no offload functions exist. Make offload var available on host and device. (rev_off_dev_to_host_cpy, rev_off_host_to_dev_cpy): New. (GOMP_OFFLOAD_run): Handle reverse offload.

Duplicate libgomp.c-c++-common/requires-4.c (as ...-4a.c) but with using a heap-allocated instead of static memory for a variable. This change and the added offload_device_gcn check prepare for pseudo-USM, where the device hardware cannot access all host memory but only managed and pinned memory; for those, requires-4.c will fail and the new check permits to add target { ! { offload_device_nvptx || offload_device_gcn } } to requires-4.c; however, it has not been added yet as pseuo-USM support is not yet on mainline. (Review is pending for the USM patches.) include/ChangeLog: * gomp-constants.h (GOMP_DEVICE_HSA): Comment out unused define. libgomp/ChangeLog: * testsuite/lib/libgomp.exp (check_effective_target_offload_device_gcn): New. * testsuite/libgomp.c-c++-common/on_device_arch.h (device_arch_gcn, on_device_arch_gcn): New. * testsuite/libgomp.c-c++-common/requires-4a.c: New test; copied from requires-4.c but using heap-allocated memory.

LoongArch always support clz and ctz instructions, so we can always use __builtin_{clz,ctz} for count_{leading,trailing}_zeros. This improves the code of libgcc, and also benefits Glibc once we merge longlong.h there. Bootstrapped and regtested on loongarch64-linux-gnu. include/ChangeLog: * longlong.h [__loongarch__] (count_leading_zeros): Define. [__loongarch__] (count_trailing_zeros): Likewise. [__loongarch__] (COUNT_LEADING_ZEROS_0): Likewise.
