When running gdb.trace/{entry-values.exp,unavailable-dwarf-piece.exp} with
board cc-with-dwz, we run into two failures related to the DW_AT_decl_file
attribute:
- The encoding DW_FOR_sdata is used for DW_AT_decl_file, while the attribute
is required to have a an "unsigned integer constant" value.
- The DW_AT_decl_file attributes refer to a file with index one, while there's
no such file.
Fix this by using DW_FOR_udata and the value 0, meaning "no file specified".
Tested on x86_64-linux with board native-gdbserver.
gdb/testsuite/ChangeLog:
2019-06-24 Tom de Vries <tdevries@suse.de>
* gdb.trace/entry-values.exp: Use DW_FORM_udata instead of
DW_FOR_sdata for DW_AT_decl_file. Use 0 for DW_AT_decl_file.
* gdb.trace/unavailable-dwarf-piece.exp: Same.
