arrays and typedefs

[Richard Buchmann <Richard dot Buchmann at lip6 dot fr>]

Hello,

I read http://gcc.gnu.org/onlinedocs/gccint/Trees.html#Trees to know how to
use the internal representation used by GCC.
I'm looking for a field or a macro to get some informations.
I'm afraid to see them missing.

Look at the example :

typedef int t1;
typedef int t2[16];

t1 var1[16]; // (1)
t2 var2;     // (2)

(1)
the original type of var1 is described by a ARRAY_TYPE node of INTEGER_TYPE.
TREE_TYPE return the original type. The TREE_TYPE macro return the original type instead of the expected ARRAY_TYPE node of TYPE_DECL node : the informations about the typedef seems to be missing.

(2)
the original type of var2 is described by a ARRAY_TYPE node if INTEGER_TYPE.
TREE_TYPE macro return the TYPE_DECL node.


Is it possible to get the full informations in the case (1) ?

Please see the attachment files to see the example (done using gcc3.0.4).

Best regards
Richard BUCHMANN
