 # Disabling switch warning 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.
