Jmp rip relative This is indicated with the RIP (64-bit) and EIP (32-bit) instruction pointer registers, which are not otherwise exposed to the program and may not exist physically. So we have to manually imitate RIP-relative addressing with what we have. g. Jan 19, 2017 · 0x7FFE9BAD116D : E9 74690000 ; jmp to 0x7FFE9BAD7AE6 I was calculating 0x7FFE9BAD116D + 6974 (remember we're on little endian) = 7FFE9BAD7AE1 , so I was confused about the 5 bytes difference. Aug 29, 2020 · So lets say I have a function at 0x7FFFFFF01000 and I'm about to write a relative jmp at 0x7FFFFFF00016 the difference between these two addresses is 0xFEA(4074) however I havent written the relative jmp yet so is the relative difference between the addresses from the address im about to write at to the start of the function or is it from the May 9, 2019 · ALL jumps are relative (to RIP), including CALL and JMP instructions, except when absolute jumps are explicit made or indirect ones In optimized compilation, NASM will try to select shorter instructions, so your conditional jump will use a signed byte offset. 4004fc: eb fa jmp 4004fd fa 4004fc eb 4004fb 01 4004fa fc 4004f9 45 4004f8 83 4004f7 00 4004f6 00 4004f5 00 4004f4 00 4004f3 fc 4004f2 45 4004f1 c7 4004f0 e5 4004ef 89 4004ee 48 4004ed 55 0x4004fc %rip Special hardware is responsible for setting %rip’s value to the next instruction. Not supported in 64-bit mode. ) Jan 21, 2020 · Hi all, Continuing work on llvm-ml (a MASM assembler)… and my latest obstacle is in enabling MASM’s convention that (unless specified) all memory location references should be RIP-relative. This is very similar to RIP-relative addressing. if the branch condition is true, they do RIP += rel32 after the usual setting RIP = end of this instruction.
