Gcc Digest, Vol 5, Issue 52

[Gary Oblock]

Almost all of the makes sense to.

I'm not sure what a conditionally initialized pointer is.

You mention VAR_DECL but I assume this is for
completeness and not something I'll run across
associated with a default def (but then again I don't
understand notion of a conditionally initialized
pointer.)

I'm at the moment only dealing with a single malloced
array of structures of the given type (though multiple types could have this property.) I intend to extend this to cover multiple array and static allocations but I need to get the easiest case working first. This means no side pointers are needed and if and when I need them pointer will get transformed into a base and index pair.

I intend to do the creation of new ssa names as a separate pass from the gimple transformations. So I will technically be creating for the duration of the pass possibly two defs associated with a single gimple statement. Do I need to delete the old ssa names
via some mechanism?

By the way this is really helpful information. The only
other person on the project, Erick, is a continent away
and has about as much experience with gimple as
me but a whole heck lot less compiler experience.

Thanks,

Gary
