Usage: rz-asm [-ACdDehLBvw] [-a arch] [-b bits] [-m plugin] [-o addr] [-s syntax]
             [-f file] [-F fil:ter] [-i skip] [-l len] 'code'|hex|-
 -a arch     Set architecture to assemble/disassemble (see -L)
 -A          Show Analysis information from given hexpairs
 -b bits     Set cpu register size (8, 16, 32, 64) (RZ_ASM_BITS)
 -B          Binary input/output (-l is mandatory for binary input)
 -c cpu      Select specific CPU (depends on arch)
 -C          Output in C format
 -d, -D      Disassemble from hexpair bytes (-D show hexpairs)
 -e          Use big endian instead of little endian
 -I          Display lifted RzIL code (same input as in -d, IL is also validated)
 -E          Display ESIL expression (same input as in -d)
 -f file     Read data from file
 -F in:out   Specify input and/or output filters (att2intel, x86.pseudo, ...)
 -h, -hh     Show this help, -hh for long
 -i len      Ignore N bytes of the input buffer
 -j          Output in JSON format
 -k kernel   Select operating system (linux, windows, darwin, ..)
 -l len      Input/Output length
 -L          List Asm plugins: (a=asm, d=disasm, A=analyze, e=ESIL, I=RzIL)
 -m plugin   List supported CPUs for the chosen plugin
 -o, -@ addr Set start address for code (default 0)
 -O file     Output file name (rz-asm -Bf a.asm -O a)
 -p          Run SPP over input for assembly
 -q          Quiet mode
 -s syntax   Select syntax (intel, att)
 -v          Show version information
 -x          Use hex dwords instead of hex pairs when assembling.
 -w          Describe opcode
 If '-l' value is greater than output length, output is padded with nops
 If the last argument is '-' reads from stdin
Environment:
 RZ_ARCH      e asm.arch # architecture to assemble/disassemble (same as rz-asm -a)

 RZ_ASM_BITS             # cpu register size (8, 16, 32, 64) (same as rz-asm -b)
 RZ_BITS      e asm.bits # cpu register size (8, 16, 32, 64) (same as rz-asm -b)
 RZ_DEBUG                # if defined, show error messages and crash signal
 RZ_NOPLUGINS            # do not load shared plugins (speedup loading)
