* MdePkg/BaseMemoryLib*: check for zero length in ZeroMem ()Ard Biesheuvel2016-11-048-8/+40
| | | | | | | | | | | | | | | | Unlike other string functions in this library, ZeroMem () does not return early when the length of the input buffer is 0. So add the same to ZeroMem () as well, for all implementations of BaseMemoryLib living under MdePkg/ This fixes an issue with the ARM implementation of BaseMemoryLibOPtDxe, whose InternalMemZeroMem code does not expect a length of 0, and always writes at least a single byte.

* MdePkg/PciSegmentLib: Optimize PCI_SEGMENT_LIB_ADDRESS()Michael Kinney2016-10-271-6/+13
| | | | | | | | | | | | | | | | | | | https://bugzilla.tianocore.org/show_bug.cgi?id=180 The PCI_SEGMENT_LIB_ADDRESS() macro puts the Segment number into bits 32..47 of the logical address that is returned. The portable method to put Segment in this bit range is to use LShitU64(). For 64-bit CPUs, this is optimized well by the compiler. For 32-bit CPUs, a call to LSHiftU64() is included in the generated binaries. However, if the Segment parameter is 0, then no shift is required. Add a check for Segment set to 0 and provide an optimized macro implementation that does not call LShiftU64().

* MdePkg/DebugLib.h: add ASSERT_RETURN_ERROR()Laszlo Ersek2016-10-251-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ASSERT_EFI_ERROR() cannot be used in BASE type modules because - the replacement text calls EFI_ERROR(), - EFI_ERROR() is defined in "MdePkg/Include/Uefi/UefiBaseType.h", - the inclusion of "UefiBaseType.h" is not required for BASE type modules. While ASSERT (!RETURN_ERROR (StatusParameter)) would be a functional statement in BASE type modules, it would be less convenient and less informative: ASSERT_EFI_ERROR() prints the actual StatusParameter. Hence add ASSERT_RETURN_ERROR(), paralleling ASSERT_EFI_ERROR(). Copy the original macro definition and update it as follows: - replace EFI with RETURN, - wrap overlong lines in the comment block and in the code, - EFI_D_ERROR is deprecated, so employ DEBUG_ERROR instead.
