| The input raw profile test has been generated from the following source code: |
| |
| ``` |
| #include <sanitizer/memprof_interface.h> |
| #include <stdlib.h> |
| #include <string.h> |
| int main(int argc, char **argv) { |
| char *x = (char *)malloc(10); |
| memset(x, 0, 10); |
| free(x); |
| __memprof_profile_dump(); |
| x = (char *)malloc(10); |
| memset(x, 0, 10); |
| free(x); |
| return 0; |
| } |
| ``` |
| |
| The following commands were used to compile the source to a memprof instrumented |
| executable and collect a raw binary format profile. Since the profile contains |
| virtual addresses for the callstack, we do not expect the raw binary profile to |
| be deterministic. The summary should be deterministic apart from changes to |
| the shared libraries linked in which could change the number of segments |
| recorded. |
| |
| ``` |
| clang -fmemory-profile -mno-omit-leaf-frame-pointer -fno-omit-frame-pointer -fno-optimize-sibling-calls -gline-tables-only -m64 -Wl,-build-id source.c -o rawprofile.out |
| |
| env MEMPROF_OPTIONS=log_path=stdout ./rawprofile.out > multi.memprofraw |
| ``` |
| |
| RUN: llvm-profdata show --memory %p/Inputs/multi.memprofraw -o - | FileCheck %s |
| |
| We expect 2 MIB entries, 1 each for the malloc calls in the program. Unlike the |
| memprof-basic.test we do not see any allocation from glibc. |
