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. 31 32 { 33 'variables': { 34 'yasm_include_dirs': [ 35 'source/config/<(OS)', 36 'source/patched-yasm', 37 ], 38 39 # The cflags used by any target that will be directly linked into yasm. 40 # These are specifically not used when building the subprograms.
