Comment:

 Commit 2d88a531b7e4dbf4016dca4b1ba3b5dc34256cf4 ("Improve warnings for
 rules that might not fire") effectively cancels the fix in commit
 419af69c1bea2cecce7b4bf58162cbfac81526f2 ("Give PrimOps a NOINLINE pragma,
 to suppress silly warnings from dsRule").

 There is a comment in `testsuite/tests/simplCore/should_compile/T7287.hs`
 that indicates this is intentional.

 I'm reopening nevertheless, to be sure, since these two commits are so
 contradictory; maybe 419af69c1bea2cecce7b4bf58162cbfac81526f2 should be
 reverted?
