Hi Luc, I was looking at whether I can use the standard LLVM GEP api to access struct and array members in sparse-llvm. I noticed that the output from sparse has byte offsets of each member - but not the member's ordinal position. To use the native LLVM methods we would have to allow LLVM to work out byte offsets, and just use the struct or array definition. This would I think make the code more robust and also lead to better optimisation. Unfortunately LLVM does not support unions so for unions a bit of what is being done now is probably needed, but even here it is better to cast a union to its member struct type and then use LLVM GEP api to access its members. What do you think? I think adding the ordinal position to sparse symbols is a trivial enhancement - do you agree?
