回复: [edk2-devel] OvmfPkgX64 doesn't build with CLANG38 (clang 14.0.3) NOOPT - undefined reference to `memcpy'

[gaoliming]

Ard:
  Jiewen has mentioned the issues caused by the structure assignment. Below structure assignment is required to be replaced by CopyMem.

  VgpuGop->GopModeInfo  = *GopModeInfo;

Thanks
