示例1: ssaValueForIdent
// ssaValueForIdent returns the ssa.Value for the ast.Ident whose path
// to the root of the AST is path. isAddr reports whether the
// ssa.Value is the address denoted by the ast.Ident, not its value.
//
func ssaValueForIdent(prog *ssa.Program, qinfo *importer.PackageInfo, obj types.Object, path []ast.Node) (value ssa.Value, isAddr bool, err error) {
switch obj := obj.(type) {
case *types.Var:
pkg := prog.Package(qinfo.Pkg)
pkg.Build()
if v, addr := prog.VarValue(obj, pkg, path); v != nil {
return v, addr, nil
}
return nil, false, fmt.Errorf("can't locate SSA Value for var %s", obj.Name())
case *types.Func:
return prog.FuncValue(obj), false, nil
}
panic(obj)
}示例2: ssaValueForExpr
// ssaValueForExpr returns the ssa.Value of the non-ast.Ident
// expression whose path to the root of the AST is path. It may
// return a nil Value without an error to indicate the pointer
// analysis is not appropriate.
//
func ssaValueForExpr(prog *ssa.Program, qinfo *importer.PackageInfo, path []ast.Node) (ssa.Value, error) {
pkg := prog.Package(qinfo.Pkg)
pkg.SetDebugMode(true)
pkg.Build()
fn := ssa.EnclosingFunction(pkg, path)
if fn == nil {
return nil, fmt.Errorf("no SSA function built for this location (dead code?)")
}
if v := fn.ValueForExpr(path[0].(ast.Expr)); v != nil {
return v, nil
}
return nil, fmt.Errorf("can't locate SSA Value for expression in %s", fn)
}示例3: ssaValueForIdent
// ssaValueForIdent returns the ssa.Value for the ast.Ident whose path
// to the root of the AST is path. It may return a nil Value without
// an error to indicate the pointer analysis is not appropriate.
//
func ssaValueForIdent(prog *ssa.Program, qinfo *importer.PackageInfo, obj types.Object, path []ast.Node) (ssa.Value, error) {
if obj, ok := obj.(*types.Var); ok {
pkg := prog.Package(qinfo.Pkg)
pkg.Build()
if v := prog.VarValue(obj, pkg, path); v != nil {
// Don't run pointer analysis on a ref to a const expression.
if _, ok := v.(*ssa.Const); ok {
v = nil
}
return v, nil
}
return nil, fmt.Errorf("can't locate SSA Value for var %s", obj.Name())
}
// Don't run pointer analysis on const/func objects.
return nil, nil
