1;; Similar to funcassigncloning.ll but hand modified to add another allocation2;; whose pruned cold context only includes an immediate caller node that itself3;; doesn't need cloning, but calls a cloned allocating function, and is in a4;; function that gets cloned multiple times for a different callsite. This test5;; makes sure the non-cloned callsite is correctly updated in all function6;; clones. This case was missed because, due to context pruning, we don't have7;; any caller edges for the first callsite, so the handling that kicks in to8;; "reclone" other callsites in cloned functions was being missed.9 10; RUN: opt -passes=memprof-context-disambiguation -supports-hot-cold-new \11; RUN: -memprof-verify-ccg -memprof-verify-nodes \12; RUN: -pass-remarks=memprof-context-disambiguation \13; RUN: %s -S 2>&1 | FileCheck %s --check-prefix=IR --check-prefix=REMARKS14 15 16target datalayout = "e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-f80:128-n8:16:32:64-S128"17target triple = "x86_64-unknown-linux-gnu"18 19;; Eventually this function will be cloned several times (for the calls to new20;; for the various callers).
