NAME
 riscemu -  RISC-V emulator in Python.

SYNOPSIS
 riscemu [-h] [--options OPTIONS] [--syscall-opts SYSCALL_OPTS] [--instruction-sets INSTRUCTION_SETS] 
              [--stack_size [STACK_SIZE]] [--flen [FLEN]] [-v] [--interactive] [--ignore-exit-code]
              file.asm [file.asm ...]

DESCRIPTION
 This emulator contains:
  -  RISC-V Assembly parser
  -  RISC-V Assembly loader
  -  Emulation for most parts of the basic RISC-V instruction set and
     the M and A extensions
  -  Naive memory emulator
  -  Basic implementation of some syscalls
  -  A debugging environment


OPTIONS
 --strict-whitespace            - Do not treat all horizontal whitespace as equivalent
 --check-prefix                 - Allows changing a default match keyword CHECK to an arbitrary keyword
 --implicit-check-not           - Adds implicit CHECK-NOT check that works on every input line
 --help                         - Display available options

 -h, --help            show this help message and exit
 --options OPTIONS, -o OPTIONS
                       Toggle options. Available options are:
                              disable_debug:        Disable ebreak instructions
                              no_syscall_symbols:   Don't add symbols for SCALL_EXIT and others
                              fail_on_ex:           If set, exceptions won't trigger the debugger
                              add_accept_imm:       Accept "add rd, rs, imm" instruction (instead of addi)
                              unlimited_regs:       Allow an unlimited number of registers
                              libc:                 Load a libc-like runtime (for malloc, etc.)
                              ignore_exit_code:     Don't exit with the programs exit code.
 --syscall-opts SYSCALL_OPTS, -so SYSCALL_OPTS
 --instruction-sets INSTRUCTION_SETS, -is INSTRUCTION_SETS
                       Instruction sets to load, available are: RV32I, RV32M, RV32A, RV32F, RV32D, Zicsr, RV_Debug. 
                       All are enabled by default
 --stack_size [STACK_SIZE]
                       Stack size of loaded programs, defaults to 8MB
 --flen [FLEN]         hardware FLEN, either 32 or 64. Defaults to 64
 -v, --verbose         Verbosity level (can be used multiple times)
 --interactive         Launch the interactive debugger instantly instead of loading any programs
 --ignore-exit-code    Ignore exit code of the program and always return 0 if the program ran to completion.
