Re: [PATCH] BaseTools/PcdValueCommon: Fix PcdDataTypeUint64 format string

["Gao, Liming" <liming.gao@intel.com>]

Ard:
  The issue is related to UINT64 definition in the different ARCHs. In BaseTools X64 and IA32,  typedef uint64_t  UINT64. uint64_t doesn't work with %llx. To support all archs and tool chain, I propose to use below style to print X64 value.

    sprintf(PcdList[Index].Value, "0x%016llx", (unsigned long long) Value);

Thanks
Liming
