# REQUIRES: riscv
# REQUIRES: python
# This test verifies that disassemble -b prints out the correct bytes and
# format for standard and unknown riscv instructions of various sizes,
# and that unknown instructions show opcodes and disassemble as "<unknown>".
# It also tests that the fdis command from examples/python/filter_disasm.py
# pipes the disassembly output through a simple filter program correctly.
