BuildPackage builds an SSA program with IR for a single package . It populates pkg by type - checking the specified file ASTs . All dependencies are loaded using the importer specified by tc which typically loads compiler export data ; SSA code cannot be built for those packages . BuildPackage then constructs an ssa . Program with all dependency packages created and builds and returns the SSA package corresponding to pkg . The caller must have set pkg . Path () to the import path . The operation fails if there were any type - checking or import errors . See .. / ssa / example_test . go for an example .
