RASM(1)
NAME
rasm -- Radare patch assembler
SYNOPSIS
rasm [-elvV] [-f file] [-d bytes] [-s offset] [-a arch] [opcode]
DESCRIPTION
Instruction assembler for multiple architectures for easily and fast
writing patch opcodes
You can get the list of the supported opcodes with the '-l' flag.
-v Enable debug output
-f file Compile assembly output from file
-d bytes Disasemble bytes
-e Use big endian
- -s offset Setup an offset to change the base address for the relative
- jumps
- -a arch Set a different architecture (x86, ppc, arm, java)
- -h Show usage help message.
OPCODES
- call [addr]
- call to address
- jmp [addr] perform a relative or absolute jump
- jz [addr] conditional jump (jump if result is zero)
- jnz [addr] conditional jump (jump if result is not zero)
- trap Trap instruction (breakpoint)
- nop Nop instruction
- push [arg] Push a number or register into the stack
- pop [arg] Pop a value from stack and store it in register arg
- int [num] Call the kernel using an interrupt or syscall
- ret return from subroutine
- ret0 return 0 from subroutine
- hang perform an infinite loop (hang on)
- mov [dst], [src]
- moves an inmediate to a register
