When building edk2 202111 with clang 14 I get the following errors:
edk2/MdeModulePkg/Include/Guid/ExtendedFirmwarePerformance.h:78:47: error: field Guid within 'FPDT_GUID_EVENT_RECORD' is less aligned than 'EFI_GUID' (aka 'GUID') and is usually due to 'FPDT_GUID_EVENT_RECORD' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
EFI_GUID Guid;
^
edk2/MdeModulePkg/Include/Guid/ExtendedFirmwarePerformance.h:173:47: error: field Guid within 'FPDT_GUID_QWORD_EVENT_RECORD' is less aligned than 'EFI_GUID' (aka 'GUID') and is usually due to 'FPDT_GUID_QWORD_EVENT_RECORD' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
EFI_GUID Guid;
^
edk2/MdeModulePkg/Include/Guid/ExtendedFirmwarePerformance.h:105:47: error: field Guid within 'FPDT_DYNAMIC_STRING_EVENT_RECORD' is less aligned than 'EFI_GUID' (aka 'GUID') and is usually due to 'FPDT_DYNAMIC_STRING_EVENT_RECORD' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
EFI_GUID Guid;
^
Has this been fixed in master?

To: devel, ross
Ross:
Do you use which tool chain? CLANG38 or CLANGPDB? I think the solution should disable this warning in tool chain configuration.
Thanks
