child node, so subsequent statements are just tucked to the parent
Compound. Additionally, consecutive (fall-through) case statements
come out messy. This is a peculiarity of the C grammar. The following:
switch (myvar) {
case 10:
k = 10;
p = k + 1;
return 10;
case 20:
case 30:
return 20;
default:
break;
}
Creates this tree (pseudo-dump):
Switch
ID: myvar
Compound:
Case 10:
k = 10
p = k + 1
return 10
Case 20:
Case 30:
return 20
Default:
break
The goal of this transform is to fix this mess, turning it into the
following:
Switch
ID: myvar
Compound:
Case 10:
k = 10
p = k + 1
return 10
Case 20:
Case 30:
return 20
Default:
break
A fixed AST node is returned. The argument may be modified.

conferring a qualifier upon the contained type.
This function fixes a decl with atomic specifiers to have a sane AST
structure, by removing spurious Typename->TypeDecl pairs and attaching
the _Atomic qualifier in the right place.
