Re: [patch] OvmfPkg/QemuBootOrderLib: Fix NOOPT build failure

Hi  Jordan,

Yes, it fails on IA32.
As far as I know, it impacts VS2012/2013/2015. 
I will create a new patch and add the impacted toolchain and arch info to the commit message.

Thanks,
Dandan

Is this failing on IA32? If so, think UINTN would be better.

You might also want to add the impacted toolchain and arch to the commit message.
