Mike Beckerle reassigned DAFFODIL-2703:
---------------------------------------
Assignee: John Interrante
> 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
> Assignee: John Interrante
> 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)
