Ard Biesheuvel 051ef932bd BaseTools/GenFw X64: Detect GOTCPRELX relaxations applied by LLD
GenFw relies on static ELF relocation tables emitted by the linker (via
the --emit-relocs command line switch). These are different from the
dynamic relocations that a dynamic loader uses: static relocations are
emitted by the compiler/assembler, and consumed by the linker to
construct the executable. Only when the load address is a priori unknown
are dynamic relocations emitted, by the linker, in a format that the
dynamic loader can consume.

This distinction is relevant because only dynamic relocations cover the
GOT, and so GOT based indirections are better avoided. Unfortunately,
there are cases where the toolchain insists on emitting GOT based symbol
references, and so we have to deal with them in one of 2 ways:

- replace GOT based symbol references with direct references, so that
  the GOT entries themselves are no longer used, and can be ignored when
  generating the PE/COFF relocation tables (AARCH64 and RISCV64 take
  this approach);

- infer the locations of the GOT slots from the references appearing in
  the code, and emit PE/COFF relocations for them so that their contents
  will be fixed up appropriately.

The latter is the approach taken by GenFw for x86_64, which is the only
feasible approach for its ISA, given that GOT slots can be used as
memory operands in many different types of instructions, not all of
which can be converted straight-forwardly.

E.g.,

   movq   foo@GOTPCREL(%rip), %rax

can always be converted into

   leaq   foo(%rip), %rax

whereas

   cmpq   foo@GOTPCREL(%rip), %rax

can only be converted under the 32-bit position dependent code model,
into

   cmpq   $foo, %rax

and so the GOT references cannot be elided when generating position
independent code, which is what GenFw requires.

To remove the need for the linker to guess where the instructions start,
the ELF psABI for x86_64 specifies a couple of relaxable alternatives
for GOTPCREL, which are used to annotate particular classes of GOT
referencing instructions that may be relaxed to their non-GOT
counterparts.

There is no specification for what --emit-relocs is supposed to produce,
or whether or not its output is supposed to reflect such relaxations.
ld.bfd and LLD behave differently in this regard, and the latter may
emit R_X86_64_REX_GOTPCRELX relocations for MOV instructions that it
already has relaxed into LEA instructions. This means the displacement
in the instruction no longer refers to the GOT slot, but directly to the
object itself, and emitting a relocation is not only unnecessary, but
also harmful as the PE/COFF loader will corrupt the object when it
applies the relocations at startup.

Under the position independent code model, the only relaxation that the
linker could have applied for a R_X86_64_REX_GOTPCRELX relocation is MOV
to LEA, so detect whether the instruction is already LEA, and ignore the
relocation if that is the case.

Code Contributions
------------------

To make a contribution to a TianoCore project, follow these steps.

#. Create a change description in the format specified below to
    use in the source control commit log.
#. Your commit message must include your ``Signed-off-by`` signature
#. Submit your code to the TianoCore project using the process
    that the project documents on its web page. If the process is
    not documented, then submit the code on development email list
    for the project.
#. It is preferred that contributions are submitted using the same
    copyright license as the base project. When that is not possible,
    then contributions using the following licenses can be accepted:

-  Apache License, Version 2.0: https://opensource.org/license/apache-2-0/
-  BSD (2-clause): https://opensource.org/license/BSD-2-Clause
-  BSD (3-clause): https://opensource.org/license/BSD-3-Clause
-  MIT: https://opensource.org/license/MIT
-  Python-2.0: https://opensource.org/license/Python-2.0
-  Zlib: https://opensource.org/license/Zlib

For documentation:

-  FreeBSD Documentation License
    https://www.freebsd.org/copyright/freebsd-doc-license.html

Contributions of code put into the public domain can also be accepted.

Contributions using other licenses might be accepted, but further
review will be required.

Developer Certificate of Origin
-------------------------------

Your change description should use the standard format for a
commit message, and must include your ``Signed-off-by`` signature.

In order to keep track of who did what, all patches contributed must
include a statement that to the best of the contributor's knowledge
they have the right to contribute it under the specified license.

The test for this is as specified in the `Developer's Certificate of
Origin (DCO) 1.1 <https://developercertificate.org/>`__. The contributor
certifies compliance by adding a line saying

Signed-off-by: Developer Name developer@example.org

where ``Developer Name`` is the contributor's real name, and the email
address is one the developer is reachable through at the time of
contributing.

::

    Developer's Certificate of Origin 1.1

    By making a contribution to this project, I certify that:

    (a) The contribution was created in whole or in part by me and I
        have the right to submit it under the open source license
        indicated in the file; or

    (b) The contribution is based upon previous work that, to the best
        of my knowledge, is covered under an appropriate open source
        license and I have the right under that license to submit that
        work with modifications, whether created in whole or in part
        by me, under the same open source license (unless I am
        permitted to submit under a different license), as indicated
        in the file; or

    (c) The contribution was provided directly to me by some other
        person who certified (a), (b) or (c) and I have not modified
        it.

    (d) I understand and agree that this project and the contribution
        are public and that a record of the contribution (including all
        personal information I submit with it, including my sign-off) is
        maintained indefinitely and may be redistributed consistent with
        this project or the open source license(s) involved.

Sample Change Description / Commit Message
------------------------------------------

::

    From: Contributor Name <contributor@example.com>
    Subject: [Repository/Branch PATCH] Pkg-Module: Brief-single-line-summary

    Full-commit-message

    Signed-off-by: Contributor Name <contributor@example.com>

Notes for sample patch email
````````````````````````````

-  The first line of commit message is taken from the email's subject
   line following ``[Repository/Branch PATCH]``. The remaining portion
   of the commit message is the email's content.
-  ``git format-patch`` is one way to create this format

Definitions for sample patch email
``````````````````````````````````

-  ``Repository`` is the identifier of the repository the patch applies.
    This identifier should only be provided for repositories other than
    ``edk2``. For example ``edk2-BuildSpecification`` or ``staging``.
-  ``Branch`` is the identifier of the branch the patch applies. This
    identifier should only be provided for branches other than
   ``edk2/master``.
    For example ``edk2/UDK2015``,
   ``edk2-BuildSpecification/release/1.27``, or
    ``staging/edk2-test``.
-  ``Module`` is a short identifier for the affected code or
   documentation. For example ``MdePkg``, ``MdeModulePkg/UsbBusDxe``, ``Introduction``, or
    ``EDK II INF File Format``.
-  ``Brief-single-line-summary`` is a short summary of the change.
-  The entire first line should be less than ~70 characters.
-  ``Full-commit-message`` a verbose multiple line comment describing
    the change. Each line should be less than ~70 characters.
-  ``Signed-off-by`` is the contributor's signature identifying them
    by their real/legal name and their email address.

Submodules
----------

The current submodules used in EDK II are in `.gitmodules <.gitmodules>`__.

To get a full, buildable EDK II repository, use following steps of git
command

.. code-block:: bash

  git clone https://github.com/tianocore/edk2.git
  cd edk2
  git submodule update --init
  cd ..

If there's update for submodules, use following git commands to get
the latest submodules code.

.. code-block:: bash

  cd edk2
  git pull
  git submodule update

Note: When cloning submodule repos, '--recursive' option is not
recommended. EDK II itself will not use any code/feature from
submodules in above submodules. So using '--recursive' adds a
dependency on being able to reach servers we do not actually want
any code from, as well as needlessly downloading code we will not
use.

**Submodule Notes**

ArmSoftFloatLib is required by OpensslLib. It's inevitable in openssl-1.1.1
(since stable201905) for floating point parameter conversion, but should be
dropped once there's no such need in future release of openssl.
