 # HOW TO WRITE CONDITIONALS IN THIS FILE
 # ======================================
 #
 # In many other places, one would write a conditional that expresses all the
 # cases when a source file is used or unused, and then either add or subtract
 # it from the sources list in that case

 # small parts of it are used in many different contexts. This combined with a
 # few static initializers floating around means that dead code stripping
 # still leaves a lot of code behind that isn't always used. For example, this
 # saves more than 40K for a smaller target like chrome_elf.
 #
 # Use static libraries for the helper stuff as well like //base/debug since
 # those things refer back to base code, which will force base compilation units
 # to be linked in where they wouldn't have otherwise. This does not include
 # test code (test support and anything in the test directory) which should use
 # source_set as is recommended for GN targets).
