type File

type File struct {
	Info *types.Info
	Pkg  *types.Package
	// contains filtered or unexported fields
}

File holds a single parsed file and associated data.

func ParseFile

func ParseFile(f string) (*File, error)

ParseFile analyzes the single file passed in.

func (*File) Check

func (f *File) Check()

check type-checks the package. The package must be OK to proceed.

func (*File) ErrorLocation

func (f *File) ErrorLocation(err *Error) string

func (*File) Valid

func (f *File) Valid() *Error

Valid checks that the go constructs used in the file, f, are valid in the subset of go used in simd translation

The go subset allows funcs that are passed parameters of basic types or slices and arrays of basic types and return int, bool, or nothing In a func only simd var declarations are allowed and they must be at the beginning of the func. The func must be of the form

{simd var declarations} {var assignments} {for loop} (optional) {var assignments} {return}
