I would like to know at which level of GCC (GENERICS, GIMPLE...) I
could get informations about the C types (created with typedef) which
are defined.
Types are represented in GENERIC. GIMPLE points to GENERIC as needed.
I would like to parse type definition in order to know if the type is
a pointer or not, for exemple, if I have the following type:
typedef struct _account{
int account_number;
float balance;
} * account;
I have tried to look at GIMPLE and IPA, however it looks like, at this
state, the work is already done and the use of the type are replaced
by the use of a "struct account * ". Moreover I can't find where this
struct is keept in gcc.
Any variable of that type will point to the TYPE_DECL which represents
the type. In the C frontend, the namespace scope will have "account"
pointing to the TYPE_DECL; see c-decl.c. After the C frontend, e.g., in
GIMPLE, that mapping is gone.
