-; Check signed minimum.
-; - CHECK is for the main loop.
-; - CHECK-SHIFT1 makes sure that the negated shift count used by the second
-;   RLL is set up correctly.  The negation is independent of the NILL and L
-;   tested in CHECK.
-; - CHECK-SHIFT2 makes sure that %b is shifted into the high part of the word
-;   before being used, and that the low bits are set to 1.  This sequence is
-;   independent of the other loop prologue instructions.
