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_utils -- 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. 29 30 if (current_toolchain == host_toolchain) { 31 32 # Various files referenced by multiple targets. 33 yasm_gen_include_dir = "$target_gen_dir/include" 34 config_makefile = "source/config/$os/Makefile" 35 version_file = "version.mac" 36 37 import("//build/compiled_action.gni") 38 39 config("yasm_config") { 40 include_dirs = [ 41 "source/config/$os", 42 "source/patched-yasm", 43 ] 44 source_prereqs = [ 45 config_makefile, 46 "source/config/$os/config.h", 47 "source/config/$os/libyasm-stdint.h", 48 ] 49 defines = [ "HAVE_CONFIG_H" ] 50 if (is_posix) { 51 cflags = [ "-std=gnu99" ] 52 } 53 } 54 55 executable("genmacro") { 56 sources = [ "source/patched-yasm/tools/genmacro/genmacro.c" ] 57 configs -= [ "//build/config/compiler:chromium_code" ] 58 configs += [ ":yasm_config", 59 "//build/config/compiler:no_chromium_code" ] 60 } 61 62 executable("genmodule") { 63 sources = [ "source/patched-yasm/libyasm/genmodule.c" ] 64 configs -= [ "//build/config/compiler:chromium_code" ] 65 configs += [ ":yasm_config", 66 "//build/config/compiler:no_chromium_code" ] 67 } 68 69 executable("genperf") { 70 sources = [ 71 "source/patched-yasm/tools/genperf/genperf.c", 72 "source/patched-yasm/tools/genperf/perfect.c", 73 ] 74 75 configs -= [ "//build/config/compiler:chromium_code" ] 76 configs += [ ":yasm_config", 77 "//build/config/compiler:no_chromium_code" ] 78 79 deps = [ ":yasm_utils" ] 80 } 81 82 #
