; REQUIRES: asserts
; SLP does not run at -O1. Loop vectorization runs, but it only
; works on loops explicitly annotated with pragmas.
; OLDPM_O1-LABEL: Pass Arguments:
; OLDPM_O1: Loop Vectorization
; OLDPM_O1-NOT: SLP Vectorizer
; OLDPM_O1: Optimize scalar/vector ops
; Everything runs at -O2.
; OLDPM_O2-LABEL: Pass Arguments:
; OLDPM_O2: Loop Vectorization
; OLDPM_O2: SLP Vectorizer
; OLDPM_O2: Optimize scalar/vector ops
; Optionally run cleanup passes.
; OLDPM_O2_EXTRA-LABEL: Pass Arguments:
; OLDPM_O2_EXTRA: Loop Vectorization
; OLDPM_O2_EXTRA: Early CSE
; OLDPM_O2_EXTRA: Value Propagation
; OLDPM_O2_EXTRA: Combine redundant instructions
; OLDPM_O2_EXTRA: Loop Invariant Code Motion

; OLDPM_O2_EXTRA: Early CSE
; OLDPM_O2_EXTRA: Optimize scalar/vector ops
; The loop vectorizer still runs at both -O1/-O2 even with the
; debug flag, but it only works on loops explicitly annotated
; with pragmas.
