It supports a large list of architectures which can be listed using the \-L flag. .Pp .Bl -tag -width Fl .It Fl a Ar arch Set architecture plugin .It Fl A Show analysis information of given hexpair string .It Fl b Ar bits Set architecture bits .It Fl B Binary input/output (\-l is mandatory for binary input) .It Fl c Ar cpu Select specific CPU (depends on \-a arch) .It Fl C Output in C format .It Fl d Disassemble hexpair bytes. rasm2 \-d 9090 .It Fl D Disassemble showing hexpair and opcode .It Fl e Use big endian (or swap endianness if used more than once) .It Fl E Output disassembled instructions in ESIL format. .It Fl f Read data from file instead of ARG. .It Fl F Ar in:out Specify input and/or output filters (att2intel, x86.pseudo, ...) .It Fl h Show usage help message. .It Fl hh Show long help message including supported assembler directives .It Fl l Ar int Input/Output length .It Fl i Ar int Ignore/skip N bytes from the beginning of the input buffer .It Fl L List supported asm plugins .It Fl o Ar offset Offset of the opcode to assemble (default is 0) .It Fl @ Ar offset Alias for -o .It Fl O Ar ofile output to file, for example 'rasm2 \-BF a a.asm' .It Fl r Show output in r2 script .It Fl s Ar syntax Select syntax output (intel, att) .It Fl w Describe opcode (whats op) .It Fl q Quiet output (handy for -L, -v, ...) .El .Sh different than filename .Pp .Bl -tag -width Fl .It Fl .intel_syntax Use intel syntax rather than att:w .It Fl .att_syntax Use ATT syntax rather than flu :w dentify the region fof aslerrger .It Fl string dentify the region fof aslerrger .It Fl .ascii .It Fl .align .It Fl .arm .It Fl .thumb .It Fl .arch .It Fl .bits .It Fl .fill .It Fl .kernel .It Fl .os .It Fl .hex .It Fl .int16 .It Fl .short .It Fl .int32 .It Fl .int64 .It Fl .glob .It Fl .equ .It Fl .org .It Fl .text .It Fl .data .El .Sh EXAMPLES .Pp Assemble opcode: .Pp $ rasm2 \-a x86 \-b 32 'mov eax, 33' .Pp Disassemble opcode: .Pp $ rasm2 \-d 90 .Sh SEE ALSO .Pp .Xr radare2(1) , .Xr rafind2(1) , .Xr rahash2(1) , .Xr rabin2(1) , .Xr radiff2(1) , .Xr ragg2(1) , .Xr rarun2(1) , .Xr rax2(1) , .Sh AUTHORS .Pp pancake
