   4
   5 # The yasm build process creates a slew of small C subprograms that
   6 # dynamically generate files at various point in the build process.  This makes
   7 # the build integration moderately complex.
   8 #
   9 # There are three classes of dynamically generated files:
  10 #   1) C source files that should be included in the build (eg., lc3bid.c)
  11 #   2) C source files that are #included by static C sources (eg., license.c)
  12 #   3) Intermediate files that are used as input by other subprograms to
  13 #      further generate files in category #1 or #2.  (eg., version.mac)
  14 #
  15 # This structure is represented with the following targets:
  16 #   1) yasm -- Sources, flags for the main yasm executable. Also has most of
  17 #              of the actions and rules that invoke the subprograms.
  18 #   2) config_sources -- Checked in version of files generated by manually
  19 #                        running configure that are used by all binaries.
  20 #   3) generate_files -- Actions and rules for files of type #3.
  21 #   4) genperf_libs -- Object files shared between yasm and the genperf
  22 #                      subprogram.
  23 #   5) genmacro, genmodule, etc. -- One executable target for each subprogram.
  24 #
  25 # You will notice that a lot of the action targets seem very similar --
  26 # especially for genmacro invocations. This makes it seem like they should
  27 # be a rule. The problem is that the correct invocation cannot be inferred
  28 # purely from the file name, or extension.  Nor is it obvious whether the
  29 # output should be processed as a source or not.  Thus, we are left with a
  30 # large amount of repetitive code.
