|
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.

$ r | cY S w xY w)aK Atomic specifiers like _Atomic(type) are unusually structured,

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.
