Since the profile contains 217cca33b4SSnehasish Kumarvirtual addresses for the callstack, we do not expect the raw binary profile to 227cca33b4SSnehasish Kumarbe deterministic. The summary should be deterministic apart from changes to 237cca33b4SSnehasish Kumarthe shared libraries linked in which could change the number of segments 247cca33b4SSnehasish Kumarrecorded. 257cca33b4SSnehasish Kumar 267cca33b4SSnehasish Kumar``` 27216575e5SSnehasish Kumarclang -fuse-ld=lld -Wl,--no-rosegment -gmlt -fdebug-info-for-profiling \ 28216575e5SSnehasish Kumar -fmemory-profile -mno-omit-leaf-frame-pointer -fno-omit-frame-pointer \ 29*b0c51f00SSnehasish Kumar -fno-optimize-sibling-calls -m64 -Wl,-build-id -Wl,-no-pie \ 30*b0c51f00SSnehasish Kumar source.c -o basic.memprofexe 317cca33b4SSnehasish Kumar 32*b0c51f00SSnehasish Kumarenv MEMPROF_OPTIONS=log_path=stdout ./basic.memprofexe > basic.memprofraw 337cca33b4SSnehasish Kumar``` 347cca33b4SSnehasish Kumar 35216575e5SSnehasish KumarRUN: llvm-profdata show --memory %p/Inputs/basic.memprofraw --profiled-binary %p/Inputs/basic.memprofexe -o - | FileCheck %s 367cca33b4SSnehasish Kumar 3711314f40SSnehasish KumarWe expect 2 MIB entries, 1 each for the malloc calls in the program.
