Baranee,
I also think the following line could be changed for smaller code gen from:
+ ModuleNameSize = AsciiStrLen("[") + AsciiStrLen (gEfiCallerBaseName) +
AsciiStrLen("] ");
To:
+ //
+ // Compute string size of module name enclosed by []
+ //
+ ModuleNameSize = 2 + AsciiStrSize (gEfiCallerBaseName);
