Re: [Crash-utility] [PATCH] bug on get_be_long() and improvement of bt

Hi Dave, These are updated patches tested with SMP system and panic task. When testing a x86 guest, I found another bug about reading cpu registers from dumpfile. Qemu simulated system is x86_64 (qemu-system-x86_64), guest OS is x86. When crash reads cpu registers from dumpfile, it uses cpu_load_32(), this will read gp registers by get_be_long(fp, 32), that is, treate them as 32bits. But in fact, qemu-system-x86_64 saves 64bits for each of them(although guest OS uses only lower 32 bits). As a result, crash gets wrong cpu gp register values. Is there any way we can know from dumpfile that these gp registers(and those similar registers) are 32bits or 64bits? -- Thanks, Hu Tao
