[llvm-dev] Instruction arguments

[Abid Malik via llvm-dev]

Thanks, Ehud.

Thanks, Johannes.
I am trying to compare the call instruction (openMP ) compatibility wrt
scheduling, iteration, and chunk size. I think accessing these constant
values makes sense to form the set of call of instructions which are
compatible. What do you think?

Can you elaborate?
"These are SSA values on which pointer equality
works, especially since constants, e.g., i32 1, are unique."

"i32 1" is constant. But how I can use this constant for equality check? It
is not a sting or datatype that can be used for binary equality check.
Thanks,
