Effectively this was used as a BOOLEAN (which is typedef of U_32/I_32), but being UDATA just taking more space than necessary on 64bit platforms. Thus compiler will be able to better pack 2 consecutive boolean fields (isIndexableDataAddrPresent and isVirtualLargeObjectHeapEnabled) Using U_32 rather than BOOLEAN to be able to consistently update DDR code (which seems not to use BOOLEAN) Signed-off-by: Aleksandar Micic <[email protected]>
