| REQUIRES: x86_64-linux |

| The input raw profile test has been generated from the following source code: |
| |
| ``` |
| #include <stdlib.h> |
| #include <string.h> |
| int main(int argc, char **argv) { |
| char *x = (char *)malloc(10); |
| memset(x, 0, 10); |
| free(x); |
| 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 -fuse-ld=lld -Wl,--no-rosegment -gmlt -fdebug-info-for-profiling \ |
| -fmemory-profile -mno-omit-leaf-frame-pointer -fno-omit-frame-pointer \ |
| -fno-optimize-sibling-calls -m64 -Wl,-build-id -no-pie \ |
| source.c -o basic.memprofexe |
| |
| env MEMPROF_OPTIONS=log_path=stdout ./basic.memprofexe > basic.memprofraw |
| ``` |
| |
| RUN: llvm-profdata show --memory %p/Inputs/basic.memprofraw --profiled-binary %p/Inputs/basic.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. |
