You are correct, ubyte 2 simply means 3rd element of the structure. This quantity is always constant (it specifies the field number), so we could have used any signed or unsigned integer type for it instead of ubyte. UByte means we are limited to at most 256 structure fields but it also makes the bytecode representation more compact. (To remove this restriction, we may migrate to UInt in the

Hi, I've another question about getelementptr. So, in the twisted mind of my little pass, I have a statement like this: %reg228-mod = getelementptr %struct.SimpleStruct* %N.1, long 0 ; <%struct.SimpleStruct*> [#uses=2] I'm not sure of the semantics of %a = getelementptr %b, long 0. I want to think that it is some kind of weird identity (no-op), judging from the operand type and the result type that is p...
