BaseTools: Optimize GenerateByteArrayValue and CollectPlatformGuids APIs
During the Incremental build GenerateByteArrayValue used to generate the ByteArrayValue even when there is no change in the PCD/VPDs. which is time consuming API based on the number of PCD/VPDs and SKU IDs. The optimization is that GenerateByteArrayValue is used to store the StructuredPcdsData in a JSON file for each of the arch. and during the Incremental build this API will check, if there is any change in the Structured PCD/VPDs then rest of the flow remains the same. if there is no change then it will return the provious build data. Flow: during the 1st build StructuredPcdsData.json is not exists, StructuredPcdsData will be dumped to json file. and it will copy the output.txt as well. Note: as the output.txt are different for different Arch, so it will be stored in the Arch folder. During the Incremental build check if there is any change in Structured PCD/VPD. if there is a change in Structured VPD/PCD then recreate the StructuredPcdsData.json, and rest of the flow remains same. if there is no change in VPD/PCD read the output.txt and return the data Unit Test: Test1: Modified the Structured Pcds default from DEC file. current flow is executing. Test2: Override the default value of the PCD from DEC file. current flow is executing. Test3: Modified/Override the PCD from DSC file. current flow executing Test4: Modified/Override the FDF from DSC file. current flow executing Test5: update the default value from Command Line.current flow executing Test6: Build without change in PCD in DSC, FDF, DEC and Command Line the proposed changes will be executing, and the return data remains the same with and without the changes. Test7: Build with and without modified the include headers of Structured PCDs. if there is any change in those Structured PCD header then current flow will be executed. With these changes it's helping to save around ~2.5min to ~3.5min of Incremental build time in my build environment.
