We rely on PIE executables to get the codegen that is suitable for
PE/COFF conversion where the resulting executables can be loaded
anywhere in the address space.
However, ELF linkers may default to disallowing text relocations in PIE
executables, as this would require text segments to be updated at
runtime, which is bad for security and increases the copy-on-write
footprint of ELF executables and shared libraries.
However, none of those concerns apply to PE/COFF executables in the
context of EFI, which are copied into memory rather than mmap()'ed, and
fixed up by the loader before launch.
So pass -z notext to the LLD linker to permit runtime relocations in
read-only sections.

The clang toolchain might default to fPIE/fPIC, which prevents
lld from linking the objects into a binary.
Specify -fno-pie -fno-pic as done on GCC to fix linking.

The ELF based toolchains use objcopy to create HII object files, which
contain only a single .hii section. This means no GNU note is inserted
that describes the object as compatible with BTI, even though the lack
of executable code in such an object makes the distinction irrelevant.
However, the linker will not add the note globally to the resulting ELF
executable, and this breaks BTI compatibility.
So let's insert a GNU BTI-compatible ELF note by hand when generating
such object files.

Replace rv64imafdc with rv64gc so that it works for gcc 12.
"g" means imafd in gcc < 12 and imafd_zifencei_zicsr in gcc >= 12.
So, replacing rv64imafdc with rv64gc will work for both gcc <12
and gcc >=12.

commit 17bd834eb5fd ("BaseTools: Factorize GCC flags")
makes GCC48_ALL_CC_FLAGS inherit from GCC_ALL_CC_FLAGS.
GCC_ALL_CC_FLAGS contains the '-Os' flag.
The latest flag in a command line overrides the previous
optimization option. This allows more specific build
configuration to override the inherited '-Os' flag.
If a build configuration includes GCC48_ALL_CC_FLAGS,
hard-coded '-Os' options are not necessary anymore.
Remove them.

Even though the presence of the 'packed' pragma should be a strong hint
that the misaligned placement of a GUID in a struct is intentional,
recent Clang versions will object nonetheless, and break the build due
to the presence of such GUIDs in the FPDT ACPI tables.
This is obviously not something we can fix in the code, so let's just
suppress the warning/error instead.

Recent GCC for ARM will complain when selecting the hard float ABI
without specifying the FPU implementation, even when just running the
preprocessor.
This all happens under the hood, and we never bothered in the past,
given that we don't emit floating point code anyway. However, to placate
newer compilers, make it explicit that the floating point ABI is always the
softfloat one, by moving the -msoft-float compiler option to
PLATFORM_FLAGS.

The global GCC_PP_FLAGS tools_def variable now contains a reference to
OpenSBI specific C preprocessor variables, which means they are added to
the command line on every architecture, not just RISC-V.
This does not currently result in any issues, but it is a bit sloppy so
let's clean this up. Given that the GCC_PP_FLAGS definition appears
twice, drop the one that carries the OpenSBI reference, and move that
reference to a new RISC-V specific variable.

The ebp/rbp register can either be used for the frame pointer or
as general purpose register. With gcc (and clang) this depends
on the -f(no-)omit-frame-pointer switch.
This patch updates tools_def.template to explicitly set the compiler
option and also add a define to allow conditionally compile code.
The new define is used to fix stack switching in TemporaryRamMigration.
The ebp/rbp must not be touched when the compiler can use it as general
purpose register. With version 12 gcc starts actually using the
register, so changing it leads to firmware crashes in some
configurations.

CLANG8ELF tool chain is added to generate ELF image, and convert to PE/COFF.
On Windows OS, set CLANG_HOST_BIN=n, set CLANG8_BIN=LLVM installed directory
For example:
set CLANG_HOST_BIN=n # use windows nmake
set CLANG8_BIN=C:\Program Files\LLVM\bin\
On Linux/Mac, set CLANG8_BIN=LLVM installed directory
This tool chain can be used to compile the firmware code. On windows OS,
Visual Studio is still required to compile BaseTools C tools and nmake.exe.
On Linux/Mac OS, gcc is used to compile BaseTools C tools. make is used
for makefile.
This tool chain is verified on OVMF Ia32, X64 and Ia32X64 to boot Shell.

GCC48_ALL_CC_FLAGS has no dependency on GCC_ALL_CC_FLAGS.
By definition, there should be such dependency.
The outcomes of this patch is that GCC48_ALL_CC_FLAGS and
other dependent configurations will inherit from the
additional "-Os" flag.
The "-Os" flag optimizes a build in size, not breaking any
build. In a gcc command line, the last optimization flag
has precedence. This means that this "-Os" flag will be
overriden by a more specific optimization configuration,
provided that this more specific flag is appended at the
end of the CC_FLAGS.

By default, gcc allows void* pointer arithmetic.
This is a GCC extension.
However:
- the C reference manual states that void*
pointer "cannot be operands of addition
or subtraction operators". Cf s5.3.1
"Generic Pointers";
- Visual studio compiler treat such operation as
an error.
To prevent such pointer arithmetic, the "-Wpointer-arith"
flag should be set for all GCC versions.
The "-Wpointer-arith" allows to:
"Warn about anything that depends on the "size of"
a function type or of void. GNU C assigns these
types a size of 1, for convenience in calculations
with void * pointers and pointers to functions."
This flag is available since GCC2.95.3 which came out in 2001.

SetupGit.py sets the git config option diff.orderFile to
{edk2 directory}/BaseTools/Conf/diff.order, to override the default order
in which files are shown in a diff/patch/whatever. This is in imitation
of what is done manually in Laszlo's Unkempt Guide.
However, the version currently in the tree is in CRLF format, which makes
git interpret e.g. *.c as matching on *.c<CR>, finding no matches and
failing to apply the desired reordering. Note: this is true regardless of
whether running on Linux or Windows.
Convert the file to LF-only to make it work as expected.

The AmlToHex script and Posix/WindowsLike wrappers convert
an AML file to a .hex file, containing a C array storing
AML bytecode. This ".hex" file can then be included in a
C file, allowing to access the AML bytecode from this C
file.
The EDK2 build system doesn't allow to a depict dependency
orders between files of different languages. For instance,
in a module containing a ".c" file and a ".asl", the ".c"
file may or may not be built prior to the ".asl" file.
This prevents any inclusion of a generated ".hex" in a
".c" file since this later ".hex" file may or may not
have been created yet.
This patch modifies the AmlToC script to generate a C file
instead of a ".hex" file.
It also adds the generation of an intermediate ".amli" file
when compiling an ASL file, and adds a rule to convert this
".amli" to a C file.
This allows to generate a C file containing the AML bytecode
from an ASL file. This C file will then be handled by the EDK2
build system to generate an object file.
Thus, no file inclusion will be required anymore. The C file
requiring the AML bytecode as a C array, and the ASL file,
will be compiled independently. The C array must be defined
as an external symbol. The linker is resolving the
reference to the C array symbol.
To summarize, the flow goes as:
-1. ASL file is compiled to AML;
-2. AML file is copied to a ".amli" intermediate file;
-3. EDK2 build system applies the rule relevant to ".amli"
files. This is, calling the "AmlToC" script, generating
a C file from the ".amli" file;
-4. EDK2 build system applies the rule relevant to C files.
This is creating an object file.
-5. EDK2 build system links the object file containing the
AML bytecode with the object file requiring it.

The VS2017 compiler reports 'warning D9035 : option
'Gm' has been deprecated and will be removed in a
future release'
The documentation for the 'Gm' option at
https://docs.microsoft.com/en-us/cpp/build/reference/gm-enable-minimal-rebuild?view=vs-2019
indicates that this option can be safely removed
from the project.
Therefore, remove the deprecated 'Gm' Visual Studio
Compiler option.

This patch reduces the size of IA32 binaries by ensuring that
no .debug_frame / .eh_frame sections are generated through forcing
SEH exception model, which is already the default in clang for X64.
EDK II does not support exceptions, and in future we should disable
them instead of switching to some other variant. Currently this
is not possible due to the following LLVM bugs:
https://bugs.llvm.org/show_bug.cgi?id=45324
https://bugs.llvm.org/show_bug.cgi?id=45325
Upon applying this patch OvmfPkgIA32.dsc compilation in DEBUG mode
gets the following size decrease with clang 9.0.1.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2487
The call stack unwindability of the COFF X64 binary requires
the binary to remain the pdata and xdata sections.
Details see the MSVC X64 calling convertion doc in below link:
https://docs.microsoft.com/en-us/cpp/build/x64-calling-convention
Current build options discard or zero the data in pdata and xdata
sections which cause the debugger cannot correctly unwind the
X64 binary call stack in the runtime.
Enhance the build options to force emit the unwind tables and
keep the data of pdata and xdata sections correct in the binary.

The "-tc" option of the iasl compiler allows to generate a
.hex file containing a C array storing AML bytecode.
An online discussion suggested that this "-tc" option
was specific to the iasl compiler and it shouldn't be relied
on. This conversation is available at:
https://edk2.groups.io/g/devel/topic/39786201#49659
A way to address this issue is to implement a compiler
independent script that takes an AML file as input, and
generates a .hex file.
This patch implements a Python script that converts an AML
file to a .hex file, containing a C array storing AML bytecode.
This scipt has been tested with the AML output from the
following compilers supported by the EDKII implementation:
* Intel ASL compiler
* Microsoft ASL compiler

The "--function-context" ("-W") option of git-diff displays the entire
body of a modified function, not just small modified hunks within the
function. It is useful for reviewers when the code changes to the function
are small, but they could affect, or depend on, control flow that is far
away in the same function.
Of course, the size of the displayed context can be controlled with the
"-U" option anyway, but such fixed-size contexts are usually either too
small, or too large, in the above scenario.
It turns out that "--function-context" does not work correctly for C
source files in edk2. In particular, labels for the goto instruction
(which the edk2 coding style places in the leftmost column) appear to
terminate "--function-context".
The "git" utility contains built-in hunk header patterns for the C and C++
languages. However, they do not take effect in edk2 because we don't
explicitly assign the "cpp" git-diff driver to our C files. The
gitattributes(5) manual explains that this is required:
> There are a few built-in patterns to make this easier, and
> tex is one of them, so you do not have to write the above in
> your configuration file (you still need to enable this with
> the attribute mechanism, via .gitattributes). The following
> built in patterns are available:
>
> [...]
>
> * cpp suitable for source code in the C and C++
> languages.
The key statement is the one in parentheses.
Grab the suffix lists from the [C-Code-File] and [Acpi-Table-Code-File]
sections of "BaseTools/Conf/build_rule.template", add "*.h" and "*.H", and
mark those as belonging to the "cpp" git-diff driver.
This change has a dramatic effect on the following command, for example:
$ git show -W 2ef0c27cb84c
