| This test ensures that llvm-profdata fails with a descriptive error message |
| when invoked on a memprof profiled binary which was built with position |
| independent code. |
| |
| 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. |
