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 # inputs 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 import("//build/config/compiler/compiler.gni") 31 32 configs_to_delete = [] 33 configs_to_add = [] 34 if (is_debug) { 35 configs_to_delete += [ 36 # Build with full optimizations even on debug configurations, because some 37 # yasm build steps (highbd_sad4d_sse2.asm) can take ~33 seconds or more in 38 # debug component builds on Windows.
