In fact, we can treate these two relocation as the same one in the riscv_elf_check_relocs. I have heard that RISC-V lld had made this improvement, and so had GNU AARCH64, they only need R_AARCH64_CALL26 for calls rather than two seperate relocations. Beside, the following PLT issue for RISC-V 32-bit glibc seems to be fixed by applying at least this patch. <https://sourceware.org/pipermail/libc-alpha/2020-August/117214.html> I have ran the toolchain regression, and everything seems fine for now. bfd/ * elfnn-riscv.c (riscv_elf_check_relocs): Treat R_RISCV_CALL and R_RISCV_CALL_PLT as the same in the riscv_elf_check_relocs.

When building with gcc with -gdwarf-5 ld tests (including ld-elf/dwarf.exp) fail because they try to read the .debug_ranges section.
