# Disabling undef, switch, format-nonliteral and tautological-undefined-compare
# warnings for clang because of test source.

# Note: On AIX, the gtest test classes linked into the libjvm.so push the TOC
# size beyond 64k, so we need to link with bigtoc. However, this means that
# -qpic=large would be advisable to lessen the performance effect of bigtoc.
# But we want to avoid imposing -qpic=large onto the regular libjvm.so, which
# has no problem with its TOC, so do this only for object files which are
# exclusive to the gtest libjvm.so.
