llvm dev - Dec 2018 - How to get the destination in a LoadInst

Hi,
I would like to get the '5'. I would like to know where the loaded value
is
stored. I don't know which method I should use of the LoadInst class.

Hope this clarifies

Thanks

Take a look at the users of the load instruction:
http://llvm.org/docs/ProgrammersManual.html#iterating-over-def-use-use-def-chains

Is this what you are looking for?

Cheers,
Florian

Thanks Florian,
I'm not sure yet but tomorrow I'll try. At the moment I don't see
why I
should iterate on a list just for getting the 5 out that LoadInst CTI on
but I'm.sure I'm missing something :)

Thanks a lot
