John Interrante commented on DAFFODIL-2703:
-------------------------------------------
Steve, I think you're right on both counts. I expanded unalignedRightFill.tdml
to unalignedRightFills.tdml (plural, attached below) with multiple roots having
different fill bytes for each root (00, 0F, F0, FF), using %#r instead of %#x,
and using unsignedInt instead of int:
[^unalignedRightFills.tdml]
With runtime1, all tests pass. With runtime2, only the 00 tests pass. And the
%#x syntax definitely produces different actual values, probably meaning the
literals don't have the same values as the %#r syntax.

> Unaligned RightFill does not unparse correctly

> Key: DAFFODIL-2703
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2703
> Project: Daffodil
> Issue Type: Bug
> Components: Back End, Back End C-Generator
> Affects Versions: 3.3.0
> Reporter: Steve Lawrence
> Priority: Major
> Attachments: unalignedRightFill.tdml, unalignedRightFills.tdml
>
>
> See the attached unalignedRightFill.tdml file for reproducible tests.
> Data is a single byte. Only the most significant bit is actual data. The
> remaining 7 bits are RightFill region using a fillByte value of 0xF0. So the
> data should always unparse to X111 0000, where the value of X comes from the
> infoset.
> Note that runtime1 and runtime2 have different behaviors, neither of which I
> think is correct:
>
>
> *unalignedRightFill_01* (bit from infoset is 1)
> should unparse to 0xF0 (1111 0000)
> runtime1 unparses to 0xBF (1011 1111)
> runtime2 unparses to 0x9F (1001 1111)
>
> *unalignedRightFill_02* (bit from infoset is 0)
> should unparse to 0x70 (0111 0000)
> runtime1 unaprses to 0x3F (0011 1111)
> runtime2 unparses to 0x1F (0001 1111)
