llvm dev - Dec 2003 - [LLVMdev] what different in following type def?

hi,

how to explain the following two statement in detail?

(1) %struct.TorRec = type { int, void ()* }

(2) "struct._GLOBAL__N_::vtable_prefix" = type { int, 
"struct.__cxxabiv1::__class_type_info"*, sbyte* }

This associates a name with a structure whose first element is a 32-bit
signed integer, and the second element is a pointer to a null-ary function
which returns void.

This associates a name with a structure whose first element is an integer,
whose second element is a pointer to the named
"struct.__cxxabiv1::__class_type_info" type, and whose third element
is a
pointer to a signed byte.

If you haven't already, you should check out the LLVM language reference
manual, where these things are defined:
