As Michael said, if DWARF were to say anything more than it does, it should be in terms of memory-addressable units; although finding specific wording that is unambiguous for all the funky architectures in the world would be something of a trick. > If we set the DW_AT_byte_size of an integer to 1, gdb will do the > address arithmetic correctly, that is, look for int_array[1] at > address int_array + 1, not + 4, but if you ask for the value of an int > variable it will only display the lower 8 bits. Truncating the value is a GDB bug. You could try specifying bit_size=32 as well as byte_size=1, and see what happens. No promises. Do you store one char per word, or multiple chars per word? If it's one char per word, then bit_size=8 should be reasonable. If it's multiple chars per word, then "char*" has to be more than a simple address, and you'll have to define a new address class (DW_ADDR_xxxxx) and teach the debugger how to interpret values with that address class. --paulr _______________________________________________ Dwarf-Discuss mailing list [email protected] http://lists.dwarfstd.org/listinfo.cgi/dwarf-discuss-dwarfstd.org
