+# Extra suppressions specific for the halfword emulator.
+
+# --- Suppress all offheap binaries ---
+# Valgrinds leak check does not recognize pointers that are stored
+# at unaligned addresses. In halfword emulator we store 64-bit pointers
+# to offheap data on 32-bit aligned heaps.
+# We solve this by suppressing allocation of all offheap structures
+# that are not referenced by other tables (ie binaries).
