Hi Bruce,
You can write LLVM IR inside D code using ldc.llvmasm.__irEx.
Perhaps that works as a quick workaround for defining calls to
intrinsics.
Very quickly, something like this:
```
alias someFunction = __irEx!("forward declaration of intrinsic",
"call intrinsic(%0,%1,%2)", int, long, void*);
```
