In recent Python versions .reason is a read-only property that simply gives you the msg value.

The compiler is crashing on the following code:

type TypeID int
func (t *TypeID) encodeType(x int) (tt TypeID, err error) {
        switch x {
        case 0:
                return t.encodeType(x * x)
        }
        return 0, nil
}
The pass marks "return struct" {tt TypeID, err error} as used,
and this causes internal check failure.
I've added the test to:

Also:

idempotency testing.

- Applied gofmt -w src misc

This CL depends on CL 6639044 being applied first.

Formatting is not idempotent for all files: In those
files the comment position has changed (due to missing
precise location information) and/or the comment formatting
cannot/is not aware of independent code re-formatting.
In general it is very hard to make format idempotent when
running it in one pass only. Leaving that aside for now.

Preparation for forthcoming CL 6624051: Will make it
easier to see if/what changes are incurred by it.

The alignment changes in this CL are due to CL 6610051
(fix to alignment heuristic) where it appears that an
old version of gofmt was run (and thus the correct
alignment updates were not done).

debug/pe: support PE files which contain no symbol table (if NumberOfSymbols is equal to 0 in the IMAGE_FILE_HEADER structure).

No longer assume that e_lfanew (in the IMAGE_DOS_HEADER strcuture) is always one byte. It is now regarded as a 4 byte uint32.

- Changed Check signature to take function parameters for
  more flexibility: Now a client can interrupt type checking
  early (via panic in one the upcalls) once the desired
  type information or number of errors is reached. Default
  use is still simple.

- Cleaned up main typechecking loops. Now does not neglect
  _ declarations anymore.

- Various other cleanups.

This code has been reviewed before. The most significant
change is to check_test which now can handle more than
one error at the same error position (due to spurious
errors - should not happen in praxis once error handling
has been fine-tuned). This change makes check_test easier
to use during development.
