Is this worth having or not?

UEFI has lots of protocols, each with a GUID, so yes, they come in handy.

I was thinking along the lines of a macro
Code:
 struc GUID def
 {
   match d1-d2-d3-d4-d5, def
    \{
      .Data1 dd 0x\#d1
      .Data2 dw 0x\#d2
      .Data3 dw 0x\#d3
      .Data4 db 0x\#d4 shr 8,0x\#d4 and 0FFh
      .Data5 db 0x\#d5 shr 40,0x\#d5 shr 32 and 0FFh,0x\#d5 shr 24 and 0FFh,0x\#d5 shr 16 and 0FFh,0x\#d5 shr 8 and 0FFh,0x\#d5 and 0FFh
    \}
 }    
placed somewhere, either directly in the source code or other include file. Not being a master of macro's I don't now how to include the curly brackets one often sees encapsulating the GUID so might be something like having an inc file as
Code:
EFI_MPS_TABLE_GUID                                         equ eb9d2d2f-2d88-11d3-9a16-0090273fc14d
EFI_MP_SERVICES_PROTOCOL_GUID                              equ 3fdda605-a76e-4f46-ad29-12f4531b3d08
... and so on    
Source asm could be something like
Code:
        mov     [SysTable],rdx
        mov     rax,[rdx+EFI_SYSTEM_TABLE.BootServices] ; EFI_BOOT_SERVICES
        mov     [EBS],rax
...
        lea     r8,[MPProtocol]
        xor     edx,edx
        lea     rcx,[_EFI_MP_SERVICES_PROTOCOL_GUID]
        mov     rax,[EBS]
        call    [rax+EFI_BOOT_SERVICES_TABLE.LocateProtocol]
...
section '.data' data readable writeable 

_EFI_MP_SERVICES_PROTOCOL_GUID  GUID EFI_MP_SERVICES_PROTOCOL_GUID

...
    

Macro can also be used for non-EFI GUID's too.

Seems some names have different GUID's such as the EDK service one above vs AMI one so separate inc files I think. Attached EDK GUID's sample. Not sure what's a good way so suggestions welcome.

Edit: As there's no discussion off the bat I'll attach the other incs. Probably EDK one will be most used.
