[edk2-devel] [PATCH V2 1/2] BaseTools:Add the FeatureFlagExpression usage to the InfBuildData
yi1 li

Tue Mar 8 13:42:06 UTC 2022
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1446
FeatureFlagExpression Support in LibraryClasses/Guids/Ppi/Protocols
section of INF file. The Pcd value in the expression is from INF or DEC
When a FeatureFlagExpression is present,if the expression evaluates
to TRUE,then the entry is valid. If the expression evaluates to FALSE,
then the EDK II build tools must ignore the entry.
This patch is going to add this feature.
