# 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
#
# Since base includes so many low-level things that vary widely and
# unpredictably for the various build types, we prefer a slightly different
# style. Instead, there are big per-platform blocks of inclusions and
# exclusions. If a given file has an inclusion or exclusion rule that applies
# for multiple conditions, prefer to duplicate it in both lists. This makes it
# a bit easier to see which files apply in which cases rather than having a
# huge sequence of random-looking conditionals.

# Base and everything it depends on should be a static library rather than
# a source set. Base is more of a "library" in the classic sense in that many
# 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 for things like
# //base/debug since those targets 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).
