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.
