Try something like this: opt -load=my_pass.so -basic-aa -run_my_pass ... Ciao, Duncan.
Hi Duncan, In case "my_pass" is compiled into a standalone executable, how can I run the specific alias analysis in the code?

Hi Welson,> In case "my_pass" is compiled into a standalone executable, how can I run the > specific alias analysis in the code?I suggest you work out what passing -basic-aa to opt does, how it works, and do the same in your code.
