; The loop sinker was running from the bottom of the loop to the top, causing
|
|
; it to miss opportunities to sink instructions that depended on sinking other
|
|
; instructions from the loop. Instead they got hoisted, which is better than
|
|
; leaving them in the loop, but increases register pressure pointlessly.
