This introduces R_RISCV_PLT32, PC-relative data relocation that takes the 32-bit relative offset to a function or its PLT entry from its relocation location. This is needed to support relative vtables on RISCV. Github PR: https://github.com/riscv-non-isa/riscv-elf-psabi-doc/pull/363 The lld handling of this reloc is D143115.
