+This is a copy of memprof-basic.test with slight changes to check that we can still read v3 of memprofraw.
+
+Inputs cannot and should not be updated.
+
+RUN: llvm-profdata show --memory %p/Inputs/basic_v4.memprofraw --profiled-binary %p/Inputs/basic_v4.memprofexe -o - | FileCheck %s
+
+We expect 2 MIB entries, 1 each for the malloc calls in the program. Any
+additional allocations which do not originate from the main binary are pruned.
