;; Avoid failures on big-endian systems that can't read the profile properly
; REQUIRES: x86_64-linux

;; TODO: Use text profile inputs once that is available for memprof.
;; This test uses the same raw profile used for memprof.ll, see instructions
;; in that file for updating.
;; Generate the profile and the IR.
; RUN: split-file %s %t

;; Generate indexed profile

;; By default we should not match profile on to manually hinted operator
;; new calls, because we don't currently override the manual hints anyway.
