RISC-V: Clarify link behaviors of R_RISCV_32/64 relocations with ABS symbol. There are two improvements, which are all referenced to aarch64, * R_RISCV_32 with non ABS symbol cannot be used under RV64 when making shard objects. * Don't need dynamic relocation for R_RISCV_32/64 under RV32/RV64 when making shared objects, if the referenced symbol is local ABS symbol. However, considering this link, https://github.com/riscv-non-isa/riscv-elf-psabi-doc/issues/341 Seems like we should makes all R_RISCV_32/64 relocs with ABS symbol that don't need any dynamic relocations when making the shared objects. But anyway, I just sync the current behavior as aarch64 ld, in case there are any unexpected behaviors happen. Passed the gcc/binutils regressions in riscv-gnu-toolchain. bfd/ * elfnn-riscv.c (riscv_elf_check_relocs): Only allow R_RISCV_32 with ABS symbol under RV64. (riscv_elf_relocate_section): R_RISCV_32/64 with local ABS symbol under RV32/RV64 doesn't need any dynamic relocation when making shared objects. I just make the implementations similar to other targets, so that will be more easy to mainatain. ld/ * testsuite/ld-riscv-elf/data-reloc: New testcases. testsuite/ld-riscv-elf/ld-riscv-elf.exp: Added new data-reloc* testcases, and need to make ifunc-seperate* testcases work for rv32. * testsuite/ld-riscv-elf/ifunc-seperate-caller-nonplt.s: Likewise. * testsuite/ld-riscv-elf/ifunc-seperate-caller-plt.s: Likewise. 2023-03-25 08:41:12 +08:00			`.macro DATA symbol`
