[edk2-devel] Building OvmfPkgX64.dsc with XCODE5 (Apple clang 12.0.5) fails in VmgExitLib

[Rebecca Cran]

I tried building OvmfPkg/OvmfPkgX64.dsc with XCODE5 (with Apple Clang 
12.0.5 from XCode 13.1) and it failed with the following error:


/Users/bcran/src/uefi/edk2/OvmfPkg/Library/VmgExitLib/VmgExitVcHandler.c:1875:9: 
error: variable 'Compacted' is used uninitialized whenever 'if' 
condition is false [-Werror,-Wsometimes-uninitialized]
     if (EcxIn == 1) {
         ^~~~~~~~~~
/Users/bcran/src/uefi/edk2/OvmfPkg/Library/VmgExitLib/VmgExitVcHandler.c:1895:12: 
note: uninitialized use occurs here
            Compacted
            ^~~~~~~~~
/Users/bcran/src/uefi/edk2/OvmfPkg/Library/VmgExitLib/VmgExitVcHandler.c:1875:5: 
note: remove the 'if' if its condition is always true
     if (EcxIn == 1) {
     ^~~~~~~~~~~~~~~~
/Users/bcran/src/uefi/edk2/OvmfPkg/Library/VmgExitLib/VmgExitVcHandler.c:1871:37:

     BOOLEAN                Compacted;
                                     ^
                                      = '\0'
