Ard Biesheuvel 12a37b2ae1 MdePkg/BaseMemoryLib*: check for zero length in ZeroMem ()
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.

Michael Kinney 2b27b55727 MdePkg/PciSegmentLib: Optimize PCI_SEGMENT_LIB_ADDRESS()
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().

Laszlo Ersek 08bcaf20b1 MdePkg/DebugLib.h: add ASSERT_RETURN_ERROR()
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.

As reported by Vishal, CompareGuid() is a hotspot, and switching from
BaseMemoryLibStm in ArmPkg/ to BaseMemoryLibOptDxe causes a noticeable
performance regression due to the fact that BaseMemoryLibOptDxe uses
unaligned accessors explicitly to implement CompareGuid() and the related
functions.

Since BaseMemoryLibOptDxe on ARM and AARCH64 can only be used in contexts
where unaligned accesses are allowed, reimplement these functions for ARM
and AARCH64 specifically, using wide accessors that can tolerate any
misalignment.

Ard Biesheuvel a37f660599 MdePkg/BaseMemoryLibOptDxe: add accelerated ARM routines
This adds ARM support to BaseMemoryLibOptDxe, partially based on the
cortex-strings library (ScanMem) and the existing CopyMem() implementation
from BaseMemoryLibStm in ArmPkg.

All string routines are accelerated except ScanMem16, ScanMem32,
ScanMem64 and IsZeroBuffer, which can wait for another day. (Very few
occurrences exist in the codebase)

Ard Biesheuvel 01f688be90 MdePkg/BaseMemoryLib: widen aligned accesses to 32 or 64 bits
Since the default BaseMemoryLib should be callable from any context,
including ones where unaligned accesses are not allowed, it implements
InternalCopyMem() and InternalSetMem() using byte accesses only.
However, especially in a context where the MMU is off, such narrow
accesses may be disproportionately costly, and so if the size and
alignment of the access allow it, use 32-bit or even 64-bit loads and
stores (the latter may be beneficial even on a 32-bit architectures like
ARM, which has load pair/store pair instructions)

Ard Biesheuvel 35071e1574 MdePkg/BaseLib AARCH64: terminate stack frame list on stack switch
When switching to the DXE phase stack, set the frame pointer to zero so
that code walking the stack frame will not try to access stack frames
belonging to the old stack.
