| # 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. |
