[LLVMdev] inttoptr and basicaa
Hi,
I am observing some incorrect behavior in basicaa, wherein two pointers that
basicaa should determine to be MustAlias are ending up NoAlias - the other
extreme :(
I am blaming this on basicaa not handling inttoptr. Here is the relevant IR
snippet.
--------------------
%sunkaddr36 = ptrtoint %struct.BitParams* %bs to i32
%sunkaddr37 = add i32 %sunkaddr36, 16
%sunkaddr38 = inttoptr i32
