llvm dev - May 2014 - [LLVMdev] Types of operands of an Instruction

Hi,

 I am trying to implement GVN which requires processing of operands of an
Instruction.
When I started to design, I assumed operands of an Instruction are of type
Instruction. But now I would like to extend to operands of other types.

I would like to know what are the other possibilities for the Type of an
operand of an Instruction.

Regards,

A good place to start would be the class hierarchy diagram here:
http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html. It looks
like all of those Values are potential operands to an instruction (in
the right circumstances: MDNodes & MDStrings are rare, but exist for
some intrinsics I believe).

The main oddity is that the "Argument" sub-hierarchy doesn't
really
exist as a separate, but is there so that people can deal with
Instructions and ConstantExprs in a uniform way.

Cheers.

Tim.
