; REQUIRES: asserts

; Check that compiling with --disable-packetizer does not crash.
; New value jumps require the feeder instruction to be in the same packet
; as the consumer (.new) instruction. When packetization is disabled, the
; NVJ pass must be skipped to avoid an assertion in the MCCodeEmitter
; ("Couldn't find producer").
;
; The branches here are non-if-convertible (due to calls), ensuring the
; compare+branch pattern survives to the NVJ pass regardless of the
; optimization pipeline used.
