RE: [cdt-dev] IScope.getPhysicalNode() not available in CDT 4.0 - answer
|
By the way, it seems that the IASTNode that I get from the scope (see
"could use this too" in the comment from the example below)
isn't the same one I got from the older IScope.getPhysicalNode().
The source locations don't match up in my analysis, that found potential
problems in OpenMP code, starts reporting all the OpenMP variables "out
of scope."
Need to look at it in more detail, haven't had time. Any ideas appreciated.

Just so there's an answer in this thread, here's what worked:
As it turns out I didn't have to use the IScope, since I had an
IASTDeclarator
already, but I've included how to do it with that since that was the
original question.
The part that wasn't apparent was the instanceof/casting of IBinding into
something that can produce an IASTNode. DUH. Seems obvious now.
If anyone knows of other classes I need to check for please let me know.
No others turned up in running on a bunch of (MPI and OpenMP) C benchmark
code I have.
Thanks, Chris (for some offline help as well.)
public IASTNode getPhysicalNode() {
IASTNode node = null;
IASTDeclarator declarator = getDeclarator();)
IASTName dn = declarator.getName();
// Also retrievable from IScope (which was original question)
IScope scope = getScope();
IName sn;
try {
sn = scope.getScopeName();
if(sn instanceof IASTName){
dn=(IASTName)sn; // could use this too *****
}
} catch (DOMException e) {return null;}
IBinding binding = dn.resolveBinding();
if (binding instanceof CFunction) {
CFunction cf = (CFunction) binding;
node = cf.getPhysicalNode();
} else if (binding instanceof CParameter) {
CParameter cp = (CParameter) binding;;
} else if (binding instanceof CVariable) {
CVariable cv = (CVariable) binding;
node = cv.getPhysicalNode();
} else if (binding instanceof CTypedef) {
CTypedef ct = (CTypedef) binding;
node = ct.getPhysicalNode();
} // any other types I can get a physical node from???
return node;
}

The scope has an IName. This means it's either an IASTName or an
IIndexName.
If it's an IASTName (I'm assuming so since the stuff you are doing is
editor based), then you can do resolveBinding() on it to get the IBinding,
at which point you can then do interesting things.
If it's an IIndexName, then ultimately it will be a PDOMName, and so you
can do a resolveBinding() on that instead.

Do you mean IScope.getParent()? Seems like this one be one level higher
than the scope itself.
or IASTDeclarator.getParent()? I'm trying to figure out if that gives the
original intent of the code. It's not apparent.
Basically, CDT 3.1 had IScope.getPhysicalNode() which returned an IASTNode.
CDT 4.0 doesn't have this method on IScope.
(Can I get it from the Binding? it's not obvious to me anyway how to get
the IASTNode from the IScope.)
Sorry if I'm being dense...
