RISC-V: Add PT_RISCV_ATTRIBUTES and add it to PHDR. We added PT_RISCV_ATTRIBUTES to program header to make .riscv.attribute easier to find in dynamic loader or kernel. Ref: https://github.com/riscv/riscv-elf-psabi-doc/pull/71 ChangeLog: bfd/ * elfnn-riscv.c(RISCV_ATTRIBUTES_SECTION_NAME): New. (riscv_elf_additional_program_headers): Ditto. (riscv_elf_modify_segment_map): Ditto. (elf_backend_additional_program_headers): Ditto. (elf_backend_modify_segment_map): Ditto. (elf_backend_obj_attrs_section): Use RISCV_ATTRIBUTES_SECTION_NAME rather than string literal. binutils/ * readelf.c(get_riscv_segment_type): New. (get_segment_type): Handle EM_RISCV. include/ * elf/riscv.h (PT_RISCV_ATTRIBUTES): New. * testsuite/ld-elf/orphan-region.ld: Discard .riscv.attributes section for simplify testcase. * testsuite/ld-riscv-elf/attr-phdr.d: New. * testsuite/ld-riscv-elf/attr-phdr.s: Ditto. * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Add attr-phdr to testcase. 2021-06-29 14:36:35 +08:00			`.attribute arch, "rv32i2p0_m2p0"`
