#
# This CMake module provides a way to get the disassembly of a function within
# an executable created with `add_executable`. The module provides a `disassemble`
# function that creates a target which, when built, outputs the disassembly of
# the given function within an executable to standard output.
#
# Parameters
# ----------
# target:
# The name of the target to create. Building this target will generate the
# requested disassembly.
#
# EXECUTABLE executable:
# The name of an executable to disassemble. This must be the name of a valid
# executable that was created with `add_executable`. The disassembly target
# thus created will be made dependent on the executable, so that it is built
# automatically when the disassembly is requested.
#
# FUNCTION function-name:
# The name of the function to disassemble in the executable.
#
# [ALL]:
# If provided, the generated target is included in the 'all' target.
#
