 (Interesting that trac does not display your updates to the patch, this
 might be very confusion when people talk about different instances of a
 patch.)

 The patch is good. I verified on openSUSE build service.

 I looked at HEAD again and the code there is not correct for negative
 numbers. I will post a fix for HEAD on Phab shortly (I am still
 validating).

 Meanwhile `0001-PPC-nativeGen-fix-shift-right-arithmetic-31-bit.patch` can
 be merged into ghc-7.10.
 Once merged, please reopen, set milestone to 8.0.1 and assign to me
 (@trommler). Thanks!
