Hello
I am trying to implement a pass which use alias analysis results.
My pass is inserted right after the 'ssa' pass.
First thing I am doing is calling compute_may_alias(), then I use the
SSA_NAME_PTR_INFO macro when needed, but I cannot find a way to use the
pt-solution correctly here.
How can you obtain the information about aliasing (e.g. what variable it
alias) from that structure?
And as a more general question, is there any docs describing the alias
analysis in more details than the internals?
Best regards,
Pierrick
