Reimport a patch to fix building gold on Cygwin64 systms: m.arena has size_t on Cygwin64 and thus errors out due to -Werror=format. gold * main.cc: Print m.arena as long long.

I just stumbled over this with 2.29.1 while building a cross-toolchain, on Cygwin64, but it's still the same for 2.30. m.arena has size_t on Cygwin64 and thus errors out due to -Werror=format. gold * main.cc: Print m.arena as long long.

Testing for the GCC version 5 or later isn't right, since C++ 11 support wasn't enabled by default until later. This patch tests the C++ standard support directly instead of inferring it from the GCC version. gold/ * incremental.cc (Sized_incremental_binary::setup_readers): Use emplace_back for C++ 11 or later.

.gnu.attributes entries from linker input files are merged to the output file, the output having the union of compatible input attributes. Incompatible attributes generally cause a linker error and no output. However in some cases only a warning is emitted, and one of the incompatible input attributes is passed on to the output. PowerPC tends to emit warnings rather than errors, and the output takes the first input attribute. For example, if we have two input files with Tag_GNU_Power_ABI_FP, the first with a value signifying "double-precision hard float, IBM long double", the second with a value signifying "double-precision hard float, IEEE long double", we'll get a warning about incompatible long double types and the output will say "double-precision hard float, IBM long double". The output attribute of course isn't correct. It would be correct to specify "IBM and IEEE long double", but we don't have a way to represent that currently. While it would be possible to extend the encoding, there isn't much gain in doing so. A shared library providing support for both long double types should link against objects using either long double type without warning or error. That is what you'd get if such a shared library had no Tag_GNU_Power_ABI_FP attribute. So this patch provides a way for the backend to omit .gnu.attributes tags from the output. * elf-bfd.h (ATTR_TYPE_FLAG_ERROR, ATTR_TYPE_HAS_ERROR): Define. * elf-attrs.c (is_default_attr): Handle ATTR_TYPE_HAS_ERROR. * elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): Use ATTR_TYPE_FLAG_INT_VAL. Set ATTR_TYPE_HAS_ERROR on finding incompatible attribute. (ppc_elf_merge_obj_attributes): Likewise. Return _bfd_elf_merge_object_attributes result. * elf64-ppc.c (ppc64_elf_merge_private_bfd_data): Return _bfd_elf_merge_object_attributes result. (cherry picked from commit 8d2c8c3d)

Some instructions in Armv8-a place a limitation on FP16 registers that can be used as the register from which to select an element from. e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction does not apply for all instructions, e.g. fcmla does not have this restriction as it gets an extra bit from the M field. Unfortunately, this restriction to S_H was added for all _Em operands before, meaning for a large number of instructions you couldn't use the full register file. This fixes the issue by introducing a new operand _Em16 which applies this restriction only when paired with S_H and leaves the _Em and the other qualifiers for _Em16 unbounded (i.e. using the full 5 bit range). Also the patch updates all instructions that should be affected by this. opcodes/ PR binutils/23192 * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. * aarch64-opc-2.c: Likewise. * aarch64-dis.c (aarch64_ext_reglane): Add AARCH64_OPND_Em16 constraint. * aarch64-opc.c (operand_general_constraint_met_p, aarch64_print_operand): Likewise. * aarch64-tbl.h (aarch64_opcode_table): Change Em to Em16 for smlal, smlal2, fmla, fmls, fmul, fmulx, sqrdmlah, sqrdlsh, fmlal, fmlsl, fmlal2, fmlsl2.
