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