LLVM: llvm::jitlink::riscv Namespace Reference (original) (raw)
Represents riscv fixups.
Ordered in the same way as the relocations in include/llvm/BinaryFormat/ELFRelocs/RISCV.def.

| CallRelaxable | An auipc/jalr pair eligible for linker relaxation. Linker relaxation will replace this with R_RISCV_RVC_JUMP or R_RISCV_JAL if it succeeds, or with R_RISCV_CALL_PLT if it fails. |
| AlignRelaxable | Alignment requirement used by linker relaxation. Linker relaxation will use this to ensure all code sequences are properly aligned and then remove these edges from the graph. |
