DxeMemoryAllocationLib: Change the behavior from returning NULL to ASSERT () PeiMemoryAllocationLib: Add ASSERT () I also add ASSERT () in Pei Service AllocatePool () to catch if allocation size > 64K DebugLib: Header file (DebugLib.h): Fix an issue in ASSERT_PROTOCOL_ALREADY_INSTALLED(Handle, Guid). In contrast with LocateProtocol (), the first & second parameter type of HandleProtocol () is EFI_HANDLE & EFI_GUID respectively. UefiLib: For UnicodeStringDisplayLength (CONST CHAR8 *String), return 0 if String is NULL. BasePrintLib: Add missing “EFIAPI” to UnicodeValueToString() and AsciiValueToString() and move their definitions from PrintLibInternal.c to PrintLib.c. Fix the comments error(Maximum Length TIME”) git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@275 6f19259b-4bc3-4df7-8a09-765794883524
