| # 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) yasm_config -- General build configuration including setting a |
| # inputs listing the checked in version of files |
| # generated by manually running configure. These manually |
| # generated files are used by all binaries. |
| # 3) yasm_utils -- Object files with memory management and hashing utilities |
| # shared between yasm and the genperf subprogram. |
| # 4) genmacro, genmodule, etc. -- One executable target for each subprogram. |
| # 5) generate_license, generate_module, etc. -- Actions that invoke programs |
| # built in #4 to generate .c files. |
| # 6) compile_gperf, compile_re2c, etc. -- Actions that invoke programs that |
| # turn intermediate files into .c files. |
