First, disallow R_X86_64_PC64 - generally only absolute relocations are allowed in getDynRel. glibc and musl don't support R_X86_64_PC64 as dynamic relocations. Second, support R_X86_64_32 as dynamic relocation for the ILP32 ABI (x32). GNU ld's behavior looks like: - R_X86_64_32 => R_X86_64_RELATIVE - R_X86_64_64 with addend 0 => R_X86_64_RELATIVE - R_X86_64_64 with non-zero addend => R_X86_64_RELATIVE64 (unsupported by musl; compilers do not generate such constructs to the best of my knowledge) For now we require R_X86_64_64 to be resolved at link-time for x32. Fix #140465
