# The yasm build process creates a slew of small C subprograms that
# dynamically generate files at various point in the build process. This makes
# the build integration moderately complex.
#
# There are three classes of dynamically generated files:
# 1) C source files that should be included in the build (eg., lc3bid.c)
# 2) C source files that are #included by static C sources (eg., license.c)
# 3) Intermediate files that are used as input by other subprograms to
# further generate files in category #1 or #2. (eg., version.mac)
#
# This structure is represented with the following targets:
# 1) yasm -- Sources, flags for the main yasm executable. Also has most of
# of the actions and rules that invoke the subprograms.
# 2) config_sources -- Checked in version of files generated by manually
# running configure that are used by all binaries.
# 3) generate_files -- Actions and rules for files of type #3.
# 4) genperf_libs -- Object files shared between yasm and the genperf
# subprogram.
# 5) genmacro, genmodule, etc. -- One executable target for each subprogram.
#
# You will notice that a lot of the action targets seem very similar --
# especially for genmacro invocations. This makes it seem like they should
# be a rule. The problem is that the correct invocation cannot be inferred
# purely from the file name, or extension. Nor is it obvious whether the
# output should be processed as a source or not. Thus, we are left with a
# large amount of repetitive code.
