On IPA-PTA field sensitivity and pointer expressions

Hi, I am working on an alias analysis using the points-to information generated during IPA-PTA. If we look at the varmap varinfo_t array in gcc/tree-ssa-struct.c, most of the constraint variable info structs contain a non-null decl field which points to a valid tree in gimple (which is an SSA
