And if it will, then we'll have to see how to fit in the thing that PLACEHOLDER_EXPR is for now. I don't know what it is used for at present, but there has to be a way (or there will have to be) to express the same thing in GIMPLE. But since Ada is lagging, like, three years on the rest of GCC, and nobody so far has explained what PLACEHOLDER_EXPR is for and if/how it has a GIMPLE equivalent... Gr.

I remember you also removed PLACEHOLDER_EXPR. That's required for Ada, so can't be removed.
