Add a check to detect that the profiled binary was build with position independent code. Add a test with a pie binary to which can be reused later when support is added. Also clean up the error messages with trailing colons. Reviewed By: tejohnson Differential Revision: https://reviews.llvm.org/D128564

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.
