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

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.

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)

This adds support for GCC 5.x in LTO mode for IA32, X64, ARM and
AARCH64. Due to the fact that the GCC project switched to a new
numbering scheme where the first digit is now incremented for every
major release, the new toolchain is simply called 'GCC5', and is
intended to support all GCC v5.x releases.
Since IA32 and X64 enable compiler optimizations (-Os) for both DEBUG
and RELEASE builds, LTO support is equally enabled for both targets.
On ARM and AARCH64, DEBUG builds are not optimized, and so the LTO
optimizations are only enabled for RELEASE.

When using GCC to build for X64, we switched to the position independent
small code model, which is much more efficient in terms of code generation
and runtime relocation footprint, and produces binaries that can execute
correctly from any offset.
However, the PIC routines are by default geared towards hosted binaries
containing symbol references that may resolve to definitions in other
dynamic objects, and for this reason, most symbol references are indirected
via a GOT entry (which also results in a .reloc fixup entry) unless we
annotate them.
For this reason, we introduced the 'protected' visibility annotation for
all symbol definitions and references, by setting the GCC visibility
pragma. However, as it turns out, this is not sufficient for all versions
of GCC, and in some cases (GCC 5.x using the GCC49 toolchain tag), may
still result in GOT based relocations.
So switch to 'hidden' visibility instead, which is slightly stronger, and
fixes this issue for the versions of GCC that exhibit the problem.

When building position independent (PIC) ELF objects, the GCC compiler
assumes that each symbol with external linkage may potentially end up
being exported from a shared library, which means that each of those
symbols may be subject to symbol preemption, i.e., the executable
linking to the shared library at runtime may override symbols exported
by the shared library, and every internal reference held by the shared
library itself *must* be made to point to the overridden version instead.
For this reason, PIC code symbol references always go via the Global
Offset Table (GOT), even if the code in question references symbols that
are defined in the same compilation unit. The GOT refers to each symbol
by absolute address, and so each entry is subject to runtime relocation.
Since not every symbol with external linkage is ultimately exported from
a shared library, the GCC compiler allows control over symbol visibility
using attributes, command line arguments and pragmas, where 'protected'
means that the symbol is only referenced by the shared library itself.
Due to the poor hygiene in EDK2 regarding the use of the 'static'
modifier, many symbols that are local to their compilation unit end up
being referenced indirectly via the GOT when building PIC code.
In UEFI, there are no shared libraries and so there is no need to deal
with symbol preemption, and we can mark every symbol reference protected.
The only method that applies to all symbol definitions as well as
declarations is the #pragma. So set the visibility 'protected' pragma when
building PIC code for X64 using GCC. Note that this affects code generated
with the -fpie compiler switch as well as the -fpic compiler switch.
