New macro OBJCOPY_STRIPFLAG is added in build_rule.template to replace
'--strip-unneeded -R .eh_frame', so that module can have some unique

In tools_def.template, set '--strip-unneeded -R .eh_frame' as default

LLVM/CLANG8 formal release http://releases.llvm.org/download.html#8.0.0
It can be downloaded and installed in Windows/Linux/Mac OS.
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.
This tool chain is verified in Windows/Linux and Mac OS.

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.

Compiler cache can greatly improve the build performance and
guarantee the build result safe. In our testing, the compiler
cache can improve the overall clean build time usually by 30+%
in linux and 10+% in windows. The compiler cache are very fit
to improve the Continuous Integration (CI) build performance.
For linux compiler cache (ccache) enabling, there is no need
to update edk2 code.
Below link has the ccache enabling referencd steps:
https://github.com/shijunjing/edk2/wiki/
Edk2-compiler-cache-enabling-steps-on-Linux
For windows compiler cache (clcache) enabling, we need update
the .PDB debugging file producing option from /Zi to /Z7,
which is to let the C object file contain its full symbolic
debugging information rather than produces a separated PDB file
for all obj files per folder. "PDB files are generated by a different
process (mspdbsrv). They arrive or are updated on disk after
cl completes a compilation or linking operation. One huge problem
with caching them is that the pdb files are input files as well as
outputs. mspdbsrv updates the file with new debug information if
the file exists beforehand. If there are several compilations going
on at once targetting the same pdb then the order the pdb gets
updated is unpredictable. All this makes caching very hard."
The /Zi issue more detail disccusion can be found:
https://github.com/frerich/clcache/issues/30
Please be aware that this change has no any impact to edk2 module
level PDB file generation, and we still can get the PDB debug file
for a .efi module. The /Z7 only impact intermediate obj files level
PDB file, which is current one PDB file (vc140.pdb) per obj folder.
Below link has the clcache enabling referencd steps:

*Various hardware and software debuggers
*Uefi code coverage tools

This statement doesn't apply to the GCC48 toolchain. I compressed 126

output size was 92.4% of the LzmaCompress output size in the IA32 case
(best relative compression: 86.01%, poorest relative compression: 97.47%
-- still a win). In the X64 case, the LzmaF86Compress output size was
92.95% of the LzmaCompress output size, on avarege (best relative

Given the consistent improvement from LzmaCompress to LzmaF86Compress,

The 'arm-linux-gnueabihf' target triplet we use for CLANG35 and
CLANG38 specifies a hardfloat target, and so the binaries that are
emitted are annotated as using VFP registers for passing floating
point arguments, even though no VFP is used anywhere in the code.
This works fine as long as we don't try to link against code
that uses software floating point, but combining object files
with different floating point calling conventions is not permitted.
So switch to the softfloat arm-linux-gnueabi triplet instead.
This affects both the name Clang uses when invoking the linker,
and the arguments it passes to it, and we are mostly interested
in the latter (since any version of GNU ld.bfd will do the right
thing as long as it targets EABI ARM)
For native builds, this change has no effect, since the unprefixed
system linker will take priority, and so Clang will pass the right
arguments to whichever linker happens to be the system linker.
For cross builds, the fact that Clang composes the name of the
linker by prefixing '-ld' with the target triplet implies that
users will have to switch to a version of binutils that targets
arm-linux-gnueabi rather than arm-linux-gnueabihf. Note that the
GCCx toolchain targets can use either when building for ARM so this
does not create a need to install two versions of the ARM cross
toolchain. Also, note that all ARM toolchains in the GCC family
are already documented as requiring a toolchain that targets
arm-linux-gnueabi and not arm-linux-gnueabihf.

The ARM linker may emit veneers, i.e., trampolines, when ordinary
direct relative branches cannot be used, e.g., for Thumb interworking
or branch targets that are out of range.
Usually, such veneers carry an absolute reference to the branch
target, which is problematic for us, since these absolute references
are not covered by annotations that are visible to GenFw in the
PE/COFF conversion, and so these absolute references are not fixed
up by the PE/COFF loader at runtime.
So switch to all ARM GNU ld toolchains to position independent veneers.

PE/COFF only has a very limited id space for runtime relocations, and
so it defines only a single relocation for movw/movt instruction pairs,
which can be combined to load a 32-bit symbol reference into a register.
For this to work as expected, these instructions must always appear in
the same order and adjacently, and this is something few compilers take
into account, unless they target PE/COFF explicitly (and this is not the
case for our ELF based toolchains)
For Clang 3.6 and later, we can pass the -mno-movt option to suppress
movw/movt pairs entirely, which works around the issue. Unfortunately,
for Clang 3.5, the option is called differently (-mllvm -arm-use-movt=0)
and mutually incompatible between 3.5 and 3.6.
Since it is desirable for the CLANG35 toolchain to be usable on newer
versions of Clang as well (given that it is the only non-LTO alternative
to CLANG38), let's work around this issue in a way that permits versions
3.5 and newer of Clang to be used with the CLANG35 profile.
So pass the -mkernel flag instead (and add -Qunused-argument so Clang
does not complain about the -mno-unaligned-access in ARM_CC_XIPFLAGS).
This also inhibits movw/movt generation, along with some other changes
(e.g., long calls) which do affect code generation but not in an
undesirable manner.

PIE code generation enabled by default, because it is a prerequisite
for ASLR to be enabled when running the executable.
This typically results in slightly larger code, but it also generates
ELF relocations that our tooling cannot deal with, so let's disable it
explicitly when using GCC49 or later for IA32. (Note that this does not
apply to X64: it uses PIE code deliberately in some cases, and our
tooling does deal with the resuling relocations)

The ElfConvert routines in GenFw don't handle the ".eh_frame" ELF section
emitted by gcc. For this reason, Leif disabled the generation of that
section for AARCH64 with "-fno-asynchronous-unwind-tables" in commit
28e80befa4 [1], and Ard did the same for IA32 and X64 in commit
26ecc55c02 [2]. (The CLANG38 toolchain received the same flag at its
inception, in commit 6f756db5ea [3].)
However, ".eh_frame" is back now; in upstream gcc commit 9cbee213b579 [4]
(part of tag "gcc-8_1_0-release"), both "-fasynchronous-unwind-tables" and
"-funwind-tables" were made the default for AARCH64. (The patch author
described the effects on the gcc mailing list [5].) We have to counter the
latter flag with "-fno-unwind-tables", otherwise GenFw chokes on
".eh_frame" again (triggered for example on Fedora 28).
"-f[no-]unwind-tables" goes back to at least gcc-4.4 [6], so it's safe to
add to GCC_AARCH64_CC_FLAGS.

Extend the CLANG38 toolchain definition so it can be used for
ARM and AARCH64 as well. Note that this requires llvm-ar and
the LLVMgold.so linker plugin.
In preparation of doing the same for GCC5, this toolchain version
also departs from the custom of using -O0 for DEBUG builds, which
makes them needlessly slow. Instead, let's add a NOOPT flavor as
well, and enable optimization for DEBUG like the other architectures
do. (Note that this will require some trivial changes to the platform
description files)

Recent distro builds of GCC 6 enable PIE linking by default, and allow
the previous behavior to be restored by passing the -no-pie command line
argument. Support for this was implemented by commits 1894a7c64c and
3380a59123 but unfortunately, it turns out that GCC 5 does not support
this command line argument, and exits with an error.
To avoid the need for yet another toolchain tag, to distinguish between
GCC 5 and GCC 6, let's use our GCC linker scripts when building objects
from .aslc files. This will ensure that the extra sections that are added
by the PIE linker are discarded from the ELF binary, and so they will not
corrupt the resulting .acpi file.
This reverts

Commit 1894a7c64c ("BaseTools/tools_def AARCH64 ARM: disable PIE
linking") works around an issue that was caught due to the fact that
PIE linking produces broken .acpi files. However, v2 of that fix
inadvertently only applied the workaround to the normal linker command
line, and not to the ASLD one, so the issue still persists.
So add the missing -no-pie options for ASLD on ARM and AARCH64.

The standard GCC preprocessor we use to preprocess device tree source
files has a whole bunch of macros predefined, among which
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1
This causes a property like 'linux,code' to be converted into '1,code'
which is obviously wrong. So let's get rid of all the predefined macros
by passing -undef to the preprocessor command line.

Some prebuilt GCC toolchains targeting aarch64 (e.g., the Debian Stretch
one) will default to building PIE executables. This has been observed to
corrupt ACPI tables built from .aslc sources, so disable PIE linking
altogether when using the GCC toolchain to build for AARCH64 or ARM.

Commit 8f0b62a5da ("BaseTools/tools_def AARCH64: enable frame pointers
for DEBUG builds") removed the -fomit-frame-pointer switch from the CFLAGS
definitions that are shared between AARCH64 DEBUG and RELEASE builds, and
moved it to the RELEASE specific ones, so that DEBUG builds can produce a
backtrace when a crash occurs.
This is actually a useful thing to have for RELEASE builds as well. AArch64
has 30 general purpose registers, and so the performance hit of having a
frame pointer is unlikely to be noticeable, nor are the additional 8 bytes
of stack space likely to present a problem.
So remove -fomit-frame-pointer altogether this time.

TianoCore BZ#700 [1]
Set the '-Wno-unused-const-variables' in RELEASE builds with the
GGC49 and GCC5 toolchain.
This fixes the RELEASE build of OVMF with GCC in version 6 or newer.
GCC 6 added the '-Wunused-const-variable' warning, which gets
activated by '-Wunused-variable' and has the following behavior:
"Warn whenever a constant static variable is unused aside from its
declaration" [2]
Commit 2ad6ba80a1 introduced a case
where exactly this happens on a RELEASE build. All uses of the static
const variable are located in debug code only, which gets thrown out
by the compiler on RELEASE builds and thus triggers the
unused-const-variable warning.
There is currently no GCC 6 toolchain target defined and doing so
would add a lot of boilerplate code. Instead, use the fact that GCC
ignores unknown '-Wno-*' options:
"[...] if the -Wno- form is used [...] no diagnostic is produced for
-Wno-unknown-warning unless other diagnostics are being produced"
This behavior is available in GCC 4.9 [3] (and also earlier, for that
matter), so add the flag to the GCC49 and GCC5 toolchain, even if
both GCC versions do not supports it.
GCC49 doesn't enables LTO whereas GCC5 does. As GCC 6.0 through 6.2
had bugs relating to LTO there can be desire to use the GCC49 target
even if compiling with GCC 6, see 432f1d83f7.
Orient the changes on 20d00edf21 which moved the
'-Wno-unused-but-set-variable' flag to RELEASE builds only, as there
it ensure that it does not gets raised if the only usage of a
variable is in (then collapsed) debug code.

[lersek@redhat.com: fix typo in subject]
While modern AARCH64 server systems use ACPI for describing the platform
topology to the OS, ARM systems and AARCH64 outside of the server space
mostly use device tree binaries, which are compiled from device tree
source files using the device tree compiler.
Currently, such source files and binaries may be kept in the EDK2 platform
trees, but are not integrated with the build, which means they need to be
kept in sync and recompiled manually, which is cumbersome.
So let's wire up BaseTools support for them: add tool definitions for the
DTC compiler and preprocessor flags that allow these source files to use
FixedPcd expressions and other macros defined by AutoGen.h
This way, a device tree binary can be built from source and emitted into
a FFS file automatically using something like:
DeviceTree.inf:
[Defines]
INF_VERSION = 0x00010019
BASE_NAME = SomePlatformDeviceTree
FILE_GUID = 25462CDA-221F-47DF-AC1D-259CFAA4E326 # gDtPlatformDefaultDtbFileGuid
MODULE_TYPE = USER_DEFINED
VERSION_STRING = 1.0
[Sources]
SomePlatform.dts
[Packages]
MdePkg/MdePkg.dec
SomePlatform.fdf:
INF RuleOverride = DTB xxx/yyy/DeviceTree.inf
[Rule.Common.USER_DEFINED.DTB]
FILE FREEFORM = $(NAMED_GUID) {
RAW BIN |.dtb
}
where it can be picked at runtime by the DTB loader that may refer to it
using gDtPlatformDefaultDtbFileGuid.
Note that this is very similar to how ACPI tables may be emitted into a
FFS file with a known GUID and picked up by AcpiTableDxe at runtime.

3.13 Options for Linking
========================
'-pie'
Produce a position independent executable on targets that support
it. For predictable results, you must also specify the same set
of options used for compilation ('-fpie', '-fPIE', or model
suboptions) when you specify this linker option.
3.18 Options for Code Generation Conventions
============================================
'-fpie'
'-fPIE'
These options are similar to '-fpic' and '-fPIC', but generated
position independent code can be only linked into executables.
Usually these options are used when '-pie' GCC option is used
during linking.
'-fpie' and '-fPIE' both define the macros '__pie__' and
'__PIE__'. The macros have the value 1 for '-fpie' and 2 for
'-fPIE'.

XIP code may execute with the MMU off, in which case all memory accesses
should be strictly aligned to their size. Some versions of GCC violate
this restriction even when -mstrict-align is passed, when performing
loads and stores that involve SIMD registers. This is clearly a bug in
the compiler, but we can easily work around it by avoiding SIMD registers
altogether when building code that may execute in such a context. So add
-mgeneral-regs-only to the AARCH64 XIP CC flags.

The AArch64 ABI classifies register x18 as a platform register, which
means it should not be used unless the code is guaranteed to run on a
platform that doesn't use it in such a capacity.
GCC does not honour this requirement by default, and so we need to tell
it not to touch it explicitly, by passing the -ffixed-x18 command line
option.
