-Upstream-Status: Pending
-
-ARM is the only architecture that has a helper function that returns
-an unbiased result. This fix is trivial enough that we can show it
-doesn't effect any of the other arches. Can we consider this a
-regression fix since it used to work until the helper was added :}
-
-Tested with no regressions on x86_64-pc-linux-gnu and arm-none-eabi.
-
-Cheers,
-Carlos.
