I think I had passed over this when I first read the 
announcement. The @llvmAttr("noalias") compiled on run.dlang.org, 
but I couldn't get the @restrict to work. I assume that uses the 
most recent version of LDC, but I don't really know.

Hmm, given that these work in LDC and not DMD, making code that 
uses it compiler-agnostic might be a little more roundabout. The 
best I could think of was something like below, unless you have 
other recommendations.

version(LDC) {
      import ldc.attributes;
}

mixin template fooImpl() {}

version(LDC) {
      void foo(@llvmAttr("noalias") void* p) {
           mixin fooImpl;
      }
} else {
      void foo(void* p) {
           mixin fooImpl;
      }
}

void main()
{

}
