Segments aren't just for data! %cs:%ip points to next instruction. ljmp , . %cs < imm1. %ip < imm2 lret pop %ip pop %cs In the x86 assembly language, the JMP instruction performs an unconditional jump. Such an instruction transfers the flow of execution by changing the instruction pointer register. There are a number of different opcodes that perform a jump; depending on whether the processor is in real mode or protected mode, and an Multi-architecture, with support for Arm, Arm64 (AArch64/Armv8), Hexagon, Mips, PowerPC, Sparc, SystemZ, & X86 (include 16/32/64bit). Clean/simple/lightweight/intuitive Added a new “Search" function to search for assembly instructions, so it is easy to grep for ROP gadgets in the binary. This will be helpful for By default it EIP RIP will be modified , update the new context but not execute the instruction to set X86 X64 cpu far jump: ljmp n. I am trying to pass a parameter to EIP register as a jump instruction to EBX vs register Stack Overflow Questions At least on x86 it actually makes sense. The first instruction that is fetched 25 Nov 2010 Hi, all. I am doing a work which is mixing up 32-bit code and 64-bit code in a process. I use LLVM JIT, and try to compile some 32-bit code. I have to do "far jump" to other code segment, to make 32-bit code can be decoded. At this part, I inline asm into the C program, and i execute it. But I got a segmentation GAS assembles ljmp *(%rsp) without a REX prefix, so the operand size is m16:32 . Long mode also allows a m16:64 form for far jmp ( REW.W FF /5 ), but doesn't dis-allow the 16:32 form. GAS unfortunately doesn't warn about an ambiguous operand-size when ljmp is used with no suffix, and binutils 2.29.1 |__ EAX (RAX for 64-bit) Accumulator for operands and results data. # |__ EBX instruction code. If the application is using a segmented. # memory model, the instruction pointer points to a logical. # memory address, referenced by the contents of the CS register . AT&T syntax uses ljmp $section, $offset , whereas Intel. Jump (jmp, ljmp). jmp disp{8|16|32} jmp *r/m{16|32} ljmp immPtr ljmp *mem48 jcc disp{8|32}. Operation. jump short or near; displacement relative to next instruction. jump far (intersegment; 4- or 6-byte immediate address. jump if condition is met; displacement relative to next instruction. Description. The jmp instruction First Fetched Instruction. • The PC runs in a quasi-real mode. – Bit 20 is shortcircuited to 1. • The first fetched address is F000:FFF0. – This is known as the reset vector. – On IBM PCs this is mapped to a ROM: the BIOS. – This gives space only to 16 bytes from the top of. ROM memory: ljmp $0xf000,$0xe05b. • This is where 64-bit Linux installations use the processo$
