+# emulated NEON code paths typically ends up 2x slower than the normal C code
+# it is supposed to replace (unlike on real devices where it is 2x to 3x
+# faster).
+#
+# What this means is that the platform image will not use NEON code paths
+# that are slower to emulate. On the other hand, it is possible to emulate
+# application code generated with the NDK that uses NEON in the emulator.
