    My umask:

```
$ umask
0027
```

Building a program with clang creates an executable with the expected permissions:

```
$ echo 'int main() { return 0; }' | bin/clang -x c - -Wl,--emit-relocs
$ ls -l a.out
-rwxr-x--- 1 hwennborg primarygroup 17464 Aug 29 11:16 a.out
```

However, processing with BOLT will generate an executable with `0777` permissions, both for instrumentation:

```
$ bin/llvm-bolt a.out -instrument -o a.out.instr
$ ls -l a.out.instr
-rwxrwxrwx 1 hwennborg primarygroup 6339568 Aug 29 11:17 a.out.instr
```

and optimization:

```
$ ./a.out.instr
$ bin/llvm-bolt a.out -o a.out.bolt -data=/tmp/prof.fdata
$ ls -l a.out.bolt
-rwxrwxrwx 1 hwennborg primarygroup 4199680 Aug 29 11:19 a.out.bolt
```
