With LDC, you have:

```D
import ldc.intrinsics: llvm_debugtrap;
```

Combining that with previous answers, you can make something like 
this:
```D
void debugbreak() nothrow @nogc @trusted {
	version(D_InlineAsm_X86_64) {
		asm nothrow @nogc {
			int 3;
		}
	} else version(LDC) {
		import ldc.intrinsics: llvm_debugtrap;
		llvm_debugtrap();
	} else {
		assert(0); // No `breakPoint` for this compiler configuration
	}
}
```
