RISC-V: PR28789, Reject R_RISCV_PCREL relocations with ABS symbol in PIC/PIE. The non-preemptible SHN_ABS symbol with a pc-relative relocation should be disallowed when generating shared object (pic and pie). Generally, the following cases, which refer to pr25749, will cause a symbol be non-preemptible, * -pie, or -shared with -symbolic * STV_HIDDEN, STV_INTERNAL, STV_PROTECTED * Have dynamic symbol table, but without the symbol * VER_NDX_LOCAL However, PCREL_HI20/LO12 relocs are always bind locally when generating shared object, so not only the non-preemptible absolute symbol need to be disallowed, all absolute symbol references need but except that they are defined in linker script. If we also disallow the absolute symbol in linker script, then the glibc-linux toolchain build failed, so regard them as pc-relative symbols, just like what x86 did. Maybe we should add this check for all pc-relative relocations, rather than just handle in R_RISCV_PCREL relocs. Ideally, since the value of SHN_ABS symbol is a constant, only S - A relocations should be allowed in the shared object, so only BFD_RELOC_8/16/32/64 are allowed, which means R_RISCV_32/R_RISCV_64. bfd/ PR 28789 * elfnn-riscv.c (riscv_elf_check_relocs): The absolute symbol cannot be referneced with pc-relative relocation when generating shared object. ld/ PR 28789 * ld/testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated. * ld/testsuite/ld-riscv-elf/pcrel-reloc*: New testcases. 2023-03-25 08:41:13 +08:00			`#source: pcrel-reloc.s`
