*** TEST RESULTS FOR COMMIT 0224619f6085908935f689b87e1ac4e460bb1e71 ***
Author: Jan Kratochvil <jan.kratochvil@redhat.com>
Branch: master
Commit: 0224619f6085908935f689b87e1ac4e460bb1e71
DWARF-5: DW_FORM_data16
DWARF-5 has new form DW_FORM_data16. The problem is that GDB cannot pass
16-byte constant as a constant value as that would require GDB to use GCC
extension __int128.
Formerly such data was coded as DW_FORM_block* so GDB still decodes
DW_FORM_data16 like DW_FORM_block*.
