# U_EXPORT (defined in unicode/platform.h) is used to set public visibility
# on classes through the U_COMMON_API and U_I18N_API macros (among others).
# When linking against the system ICU library, we want its symbols to have
# public LTO visibility. This disables CFI checks for the ICU classes and
# allows whole-program optimization to be applied to the rest of Chromium.
#
# Both U_COMMON_API and U_I18N_API macros would be defined to U_EXPORT only
# when U_COMBINED_IMPLEMENTATION is defined (see unicode/utypes.h). Because
# we override the default system UCHAR_TYPE (char16_t), it is not possible
# to use U_COMBINED_IMPLEMENTATION at this moment, meaning the U_COMMON_API
# and U_I18N_API macros are set to U_IMPORT which is an empty definition.
#
# Until building with UCHAR_TYPE=char16_t is supported, one way to apply
# public visibility (and thus public LTO visibility) to all ICU classes is
# to define U_IMPORT to have the same value as U_EXPORT. For more details,
# please see: https://crbug.com/822820
