dwarf.exp: In 64-bit units, emit also abbrev offset as a 64-bit field
Dwarf::tu and Dwarf::cu allow selection of units with 64-bit offsets
through an option. When selected, unit size is encoded properly, but
offset to abbreviation unit is still encoded in a 4-byte field. This
patch fixes the problem.
Reproducer:
Dwarf::assemble "blah.s" {
tu {is_64 1 version 4 addr_size 8} 0x1122334455667788 the_type {
type_unit {} { the_type: }
}
cu {is_64 1 version 4 addr_size 8} {
compile_unit {{language @DW_LANG_C}} {}
}
}
gdb/testsuite:
* lib/dwarf.exp (Dwarf::cu, Dwarf::tu): Emit
${_cu_offset_size} bytes abbrev offset.
