The function initializer_of_builtin_cpu is itself dead code and does not seem to get eliminated, which is probably a separate issue.
Expected Behavior
The shader should validate.

Removing the inline `asm` line makes the validator pass.
#### Disassembly
```

The function `initializer_of_builtin_cpu` is itself dead code and does not seem to get eliminated, which is probably a separate issue.
### Expected Behavior
