| **R_RISCV_HI20**             | High 20 bits of a 32-bit address                                                       | Loads the upper 20 bits of an address into a register; paired with LO12 to form complete addresses. Example symbols: `randomval`, `usrid`, `pi`, `e`. |
| **R_RISCV_LO12_I**           | Low 12 bits for I-type instructions                                                   | Completes address formation started by HI20; used for load/store and immediate operations. “I” = I-type format. |
| **R_RISCV_CALL**             | Function call relocations                                                              | Used for `jal` (jump and link) instructions to call functions; supports local (`is_prime`, `square`, `pick_prime`) and external (`printf`) functions; can span multiple instructions for far targets. |
| **R_RISCV_BRANCH**           | Conditional branch instructions                                                        | Used for `if` statements and loops; targets local labels like `.L4`, `.L6`, `.L10`. |
| **R_RISCV_RVC_BRANCH**       | Compressed branch instructions                                                         | 16-bit compressed versions of branch instructions; more efficient encoding for short branches. |
| **R_RISCV_RVC_JUMP**         | Compressed jump instructions                                                           | 16-bit compressed unconditional jumps to nearby labels. |
| **R_RISCV_RELAX**            | Linker relaxation hint                                                                 | Appears with `*ABS*` value; tells the linker it can optimize instruction sequences, possibly shortening them. |
| **Global Symbols**           | Externally visible symbols                                                             | e.g., `pi`, `e`. |
| **Static Symbol**            | Internal symbol within the file                                                        | e.g., `randomval`. |
| **External Symbol**          | Defined elsewhere                                                                     | e.g., `usrid`. |
| **String Literals**          | Format strings for functions like `printf`                                            | e.g., `.LC0`, `.LC1`, etc. |
| **Local Functions**          | Functions defined within the file                                                     | e.g., `is_prime`, `square`, `pick_prime`. |
| **External Function**        | Functions defined externally                                                          | e.g., `printf`. |
