+# These are applied to every single compile in the build and most of them are
+# only relevant to a few files. This bloats command lines and causes
+# unnecessary recompiles when flags are flipped.
+#
+# To pass defines to source code from the build, use the buildflag system which
+# will write headers containing the defines you need. This isolates the define
+# and means its definition can participate in the build graph, only recompiling
+# things when it actually changes.
+#
+# See //build/buildflag_header.gni for instructions on generating headers.
+#
+# This will also allow you to scope your build flag to a BUILD.gn file (or a
+# .gni file if you need it from more than one place) rather than making global
+# flags. See //build/config/BUILDCONFIG.gn for advice on where to define
+# build flags.
