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 ā€™-lā€™ 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
