# libgcc.a(_popcountsi2.o) uses 4-byte wchar_t yet the output is to
# use 2-byte wchar_t; use of wchar_t values across objects may fail
#
# libgcc does not have any occurences of wchar_t in its sources or the
# documentation, so it's safe to assume that we can ignore this warning.

# So far, this only happens with arm due to popcount even though x86 and
# x86_64 also have to rely on libgcc's popcount. Therefore, we only disable
# this for arm to make sure this doesn't mask other issues in the future.
