[Bug gdb/15684] New: info mem command for 32 bits host/64 bits target truncates addresses


http://sourceware.org/bugzilla/show_bug.cgi?id=15684

            Bug ID: 15684
           Summary: info mem command for 32 bits host/64 bits target
                    truncates addresses
           Product: gdb
           Version: 7.6
            Status: NEW

          Reporter: ktlnu at yahoo dot com

When running gdb on 32 bits host for 64 bits target architecture, âinfo memâ
command truncates the target address to 32 bits, like in the example below:

    (gdb) set architecture powerpc:common64
    The target architecture is assumed to be powerpc:common64
    (gdb) mem 0x100000000 0x200000000 rw
    (gdb) info mem
    Using user-defined memory regions.
    Num Enb Low Addr           High Addr          Attrs
    1   y   0x0000000000000000 0x0000000000000000 rw nocache
