func Walk ¶

func Walk(pkg *ir.PkgContainer) *ir.AnalyzedPackage

Purpose of walk: - collect string literals - collect method declarations - collect global variables - collect local variables and set offset - determine struct size and field offset - determine Types of variable declarations - attach type to every expression - transmit ok syntax context - (hope) attach type to untyped constants - (hope) transmit the need of interface conversion
