# than when invoked with -O0, regardless of anything else we're using
# to suppress optimizations. Therefore, we need to explicitly pass -O0 to it

# when compiling the tests, which will throw an error if some special macros
# (such as __OPTIMIZE__ and IS_IN_BUILD) aren't defined. To avoid this, we
