The memprof profile reader tests rely on binary data which is generated from and meant to be interpreted on little endian architectures. Add a REQUIRES: x86_64-linux clause to both tests to ensure they don't fail on big endian targets such as ppc.

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.
