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 \ 29216575e5SSnehasish Kumar -fno-optimize-sibling-calls -m64 -Wl,-build-id source.c -o basic.memprofexe 307cca33b4SSnehasish Kumar 317cca33b4SSnehasish Kumarenv MEMPROF_OPTIONS=log_path=stdout ./rawprofile.out > basic.memprofraw 327cca33b4SSnehasish Kumar``` 337cca33b4SSnehasish Kumar 34216575e5SSnehasish KumarRUN: llvm-profdata show --memory %p/Inputs/basic.memprofraw --profiled-binary %p/Inputs/basic.memprofexe -o - | FileCheck %s 357cca33b4SSnehasish Kumar 3611314f40SSnehasish KumarWe expect 2 MIB entries, 1 each for the malloc calls in the program.
