[edk2] [PATCH] MdeModulePkg SmiHandlerProfile: Fix no PDB case handling incorrectly
Posted by Star Zeng 7 years, 7 months ago 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=569

The PdbStringOffset should be set to 0 for no PDB case,
then SmiHandlerProfileInfo can use it to know whether
there is PCD info or not.
