# FIXME: So fun anecdote for later, originally I wanted to use fva 0x804af40 (parse_ls_colors)
# out of vdir for this test, but unfortunately, we detect the codeblock of that fva
# as 0x804af09, which crosses function boundaries into the function decode_switches.
# Reason being is that at VA 0x804af31, there's a call to error() with value 2 as the first
# parameter, which according to the man page for error means it should quit out. We don't grab
# that at codeflow time (because such things would require an emulator with knowledge of calling
# conventions)
# But that raises the question if makeFunction should split the codeblock
# or if we ignore that and just let the CodeBlockGraph stuff do it all for us,
# or if we should allow codeflow to carry an emulator with it.
