| 4 | # JMP rel8 (opcode EB) |
| 5 | # JMP rel32 (opcode E9) |
| 6 | # JMP r/m32 (opcode FF /4) with register operands |
| 7 | # JMP m32 (opcode FF /4) with memory operands |
| 8 | # SPECIAL CASE: When Mod=00 and R/M=101 (EBP), this doesn't actually refer to [EBP]. |
| 9 | # Instead, it's a special case that indicates a 32-bit displacement-only addressing mode. |
| 10 | # JMP m32 (opcode FF /4) with displacement |
| 11 | # JMP m32 (opcode FF /4) with SIB byte |
| 12 | # SPECIAL CASE: These SIB encodings with EBP as base register have special rules. |
| 13 | # When the SIB byte has Base=101 (EBP) and Mod=00, the base register is not used. |
| 14 | # Instead, a 32-bit displacement follows the SIB byte (similar to the Mod=00, R/M=101 special case). |
| 15 | # These instructions are commented out because they're not correctly recognized by many disassemblers, |
| 16 | # including Ghidra and online disassemblers, due to their unusual encoding. |
| 17 | # JMP m32 (opcode FF /4) with direct memory operand |
| 18 | # JMP m32 (opcode FF /4) with segment override prefixes |
