Commit 2cb8743524 eliminates possible NULL
pointer dereference in GenFfs tool source codes. However, it doesn't
correctly handle the case when the input file is of size 0. This will lead
to possible build issues.
This commits refine the logic to handle the above case.

structure layout is adjusted to keep the natural alignment and version
is updated to 6.
Note: As the PCD database structure layout is adjusted, the structure
definition in MdeModulePkg/Include/Guid/PcdDataBaseSignatureGuid.h and
PCD drivers also need to be updated. That means the source code and
BaseTools need to be upgraded at the same time, and if they are not

When building PIE (ET_DYN) executables, an additional RELA section is
emitted (in addition to the per-section .rela.text and .rela.data sections)
that is intended to be resolved at runtime by a ET_DYN compatible loader.
At the moment, due to the fact that we don't support GOT based relocations,
this dynamic RELA section only contains relocations that are redundant,
i.e., each R_xxx_RELATIVE relocation it contains duplicates a R_xxx_xx64
relocation appearing in .rela.text or .rela.data, and so we can simply
ignore this section (and we already ignore it in practice due to the fact
that it points to the NULL section, which has the SHF_ALLOC bit cleared).

- we must check that a dynamic RELA section exists;
- we must filter out duplicates between .rela and .rela.xxx, to prevent
emitting duplicate fixups into the PE/COFF .reloc section.

The CLANG38 toolchain creates a PIE binary at link time. This is
necessary since the LTO code generation may otherwise result in
code that cannot execute correctly when loaded above 2 GB.
PIE executables contain a RELA section consisting of dynamic
relocation entries that are intended for consumption by the loader
at runtime. For this reason, it has the SHF_ALLOC attribute set by
default, and will be identified by GenFw as a section that needs to
be copied into the PE/COFF binary, resulting in waste of space since
the PE/COFF loader does not use this data at all.
So mark the RELA section as informational: this will prevent the
linker from setting the SHF_ALLOC attribute, causing GenFw to
ignore it.

CLANG38 enable LLVM Link Time Optimization (LTO) and code size

improvement. CLANG38 X64 code is small code model + PIE.
CLANG LTO needs PIE in link flags to generate PIE code correctly,
otherwise the PIE is not really enabled. (e.g. OvmfPkgX64 will
hang in 64bits SEC at high address because of small model code
displacement overflow).
Test pass platforms: OVMF (OvmfPkgIa32.dsc, OvmfPkgX64.dsc and
OvmfPkgIa32X64.dsc).
Test compiler and linker version: LLVM 3.8, GNU ld 2.26.
Example steps to use the CLANG38 tool chain to build OVMF platform:
1. Download and extract the llvm 3.8.0 Pre-Built Binaries from
http://www.llvm.org/releases/ (e.g. http://www.llvm.org/releases/
3.8.0/clang+llvm-3.8.0-x86_64-linux-gnu-ubuntu-16.04.tar.xz and
extract it as ~/clang38).
2. Copy LLVMgold.so from https://github.com/shijunjing/edk2/blob/
llvm/BaseTools/Bin/LLVMgold.so to above clang lib folder (e.g.
~/clang38/lib/LLVMgold.so)
3. Install new version linker with plugin support (e.g. ld 2.26 in

$ cd edk2
$ git checkout llvm
$ export CLANG38_BIN=path/to/your/clang38/

assume that any code executing with the MMU on may perform unaligned

unaligned accesses should be allowed if supported by the CPU)

For X64/GCC, we use position independent code with hidden visibility
to inform the compiler that symbol references are never resolved at
runtime, which removes the need for PLTs and GOTs. However, in some
cases, GCC has been reported to still emit PLT based relocations, which
we need to handle in the ELF to PE/COFF perform by GenFw.
Unlike GOT based relocations, which are non-trivial to handle since the
indirections in the code can not be fixed up easily (although relocation
types exist for X64 that annotate relocation targets as suitable for
relaxation), PLT relocations simply point to jump targets, and we can
relax such relocations by resolving them using the symbol directly rather
than via a PLT entry that does nothing more than tail call the function
we already know it is going to call (since all symbol references are
resolved in the same module).
So handle R_X86_64_PLT32 as a R_X86_64_PC32 relocation.

The ADRP instruction in the AArch64 ISA requires the link time and load time
offsets of a binary to be equal modulo 4 KB. The reason is that this instruction
always produces a multiple of 4 KB, and relies on a subsequent ADD or LDR
instruction to set the offset into the page. The resulting symbol reference
only produces the correct value if the symbol in question resides at that
exact offset into the page, and so loading the binary at arbitrary offsets
is not possible.
Due to the various levels of padding when packing FVs into FVs into FDs, this
alignment is very costly for XIP code, and so we would like to relax this
alignment requirement if possible.
Given that symbols that are sufficiently close (within 1 MB) of the reference
can also be reached using an ADR instruction which does not suffer from this
alignment issue, let's replace ADRP instructions with ADR after linking if
the offset can be encoded in this instruction's immediate field. Note that
this only makes sense if the section alignment is < 4 KB. Otherwise,
replacing the ADRP has no benefit, considering that the subsequent ADD or
LDR instruction is retained, and that micro-architectures are more likely
to be optimized for ADRP/ADD pairs (i.e., via micro op fusing) than for
ADR/ADD pairs, which are non-typical.

Since IA32 and X64 enable compiler optimizations (-Os) for both DEBUG

To accommodate upcoming GCCx toolchain versions that require 'gcc' to
be used as the linker in order to support LTO, switch GCC44 and later
(including CLANG35) to a new DLINK build rule that invokes 'gcc' as the
linker instead of 'ld'. Since gcc expects its command line arguments in
a different format, and expects arguments that it needs to pass to the
linker to be prefixed with '-Wl,', this involves changes to most of the
DLINK_FLAGS definitions in tools_def.template, as well as some changes to
module .INF files that set their own linker options.

Before we can make non-backward compatible changes to the GCC build rules
regarding the use of the 'gcc' binary as the linker, clone the existing
GCC build rules into a 'GCCLD' build rule family, and move the legacy
toolchains UNIXGCC, CYGGCC, CYGGCCxASL and ELFGCC over to it.

Some versions of Clang fail on every input file when using the
-save-temps options, and produces the following heplful error message:
<unknown>:0: error: Undefined temporary symbol
Simply dropping the option for CLANG35 is the simplest way around this,
since the value of storing .i and .s files is dubious anyway.
Also, drop the arm-use-movt option, which does not appear to be
supported anymore by recent versions of clang.
