# elf2hex (https://github.com/sifive/elf2hex)
# The elf2hex utility to converts executable files into hexadecimal files for Verilog simulation.
# Note: The exe2hex utility that comes with Spike doesn’t work for our purposes because it doesn’t
# handle programs that start at 0x80000000. The SiFive version above is touchy to install.
# For example, if Python version 2.x is in your path, it won’t install correctly.
# Also, be sure riscv64-unknown-elf-objcopy shows up in your path in $RISCV/riscv-gnu-toolchain/bin
# at the time of compilation, or elf2hex won’t work properly.
