|
; ARM has a peephole optimization which looks for a def / use pair. The def
|
|
; produces a 32-bit immediate which is consumed by the use. It tries to
|
|
; fold the immediate by breaking it into two parts and fold them into the
|
|
; immmediate fields of two uses. e.g
|
|
; movw r2, #40885
|
|
; movt r3, #46540
|
|
; add r0, r0, r3
|
|
; =>
|
|
; add.w r0, r0, #3019898880
|
|
; add.w r0, r0, #30146560
|
|
;
|
|
; However, this transformation is incorrect if the user produces a flag. e.g.
|
|
; movw r2, #40885
|
|
; movt r3, #46540
|
|
; adds r0, r0, r3
|
|
; =>
|
|
; add.w r0, r0, #3019898880
|
|
; adds.w r0, r0, #30146560
|
|
; Note the adds.w may not set the carry flag even if the original sequence
|
|
; would.
