This patch provides LLVM support for Mesa3D, enabling llvmpipe
software rasterizer if Gallium swrast is selected.
In case Gallium r600 is selected, llvm AMDGPU backend is built.
Having llvm installed also enables radeonsi Gallium driver, but
it is not provided with this patch as it hasn't been tested.
It uses llvm-config (host variant) installed in STAGING_DIR/usr/bin
to get LLVM libraries. Assuming that LLVM version 5.0.1 is installed,
llvm-config --libs will output -lLLVM-5.0.

The AMDGPU backend provides ISA code generation for AMD GPU's,
starting with the R600 family up until the current GCN families.
It should not be confused with the AMDGPU Linux kernel DRM driver.

This patch installs LLVM tools and libraries for the host and
libLLVM.so for the target.
In order to cross-compile LLVM for the target, LLVM
must be installed on the host, or at least llvm-tblgen.
This is necessary as the path to host's llvm-tblgen must
be specified when cross-compiling using the LLVM_TABLEGEN option.
Also, a version of llvm-config that can run on the host will
be required by packages that link with LLVM libraries, so we
need to generate it and install it in STAGING_DIR/usr/bin.
It is important to remark why we need llvm-config(host variant)
installed in STAGING dir. This tool is necessary to build
applications that use LLVM, as it prints the compiler flags,
linker flags and object libraries needed to link against LLVM libs.
More info: https://bugs.chromium.org/p/chromium/issues/detail?id=219369
The original idea was to compile only llvm-tblgen and llvm-config
for the host, as they are the only necessary components. However,
llvm-config tool does not work as expected if it is not linked with
libLLVM.so, so we must also enable LLVM_LINK_LLVM_DYLIB, what builds
LLVM as a single shared library and links LLVM tools with it.
More info: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224847
in comment #11.
If we don't build full LLVM for the host, it would be necessary to
patch configure.ac from mesa3d if we want dynamic linking, because it
uses llvm-config (host variant installed in STAGING_DIR) to get the
necessary LLVM libraries to link with, which has the following problems:
- llvm-config --shared mode outputs static (even if LLVM is built as
one shared library) which leads to link issues with libgallium.
- llvm-config --libs outputs all LLVM tiny libs: -lLLVMLTO,
-lLLVMPasses,etc instead of the single shared library containing
all LLVM components (-lLLVM-5.0)
Mesa tries to execute: llvm-config --link-shared --libs, but this outputs
llvm-config: error: libLLVM-5.0.so is missing.
Given that these problems may arise with other packages that use LLVM,
it is preferable to do a full build for the host. Also, having a
complete installation of LLVM on the host will also facilitate the
integration of Clang front-end, which is going to be added in a future
patch.
As option LLVM_BUILD_LLVM_DYLIB is enabled for the llvm target variant,
a single shared library containing all LLVM components is built.
This option is not compatible with BUILD_SHARED_LIBS, which generates
one .so per library and is only recommended for use by LLVM developers.
Tools and utils are not built for the target. The patch aims to provide
LLVM support for other packages.
The main options needed to cross-compile LLVM are the following ones:
LLVM_TABLEGEN
CMAKE_CROSSCOMPILING
LLVM_DEFAULT_TARGET_TRIPLE
LLVM_HOST_TRIPLE
LLVM_TARGET_ARCH
LLVM_TARGETS_TO_BUILD

[Thomas:
- add dependency on thread and C++ and update the Config.in comment
accordingly.
- make the Config.in comment depend on BR2_PACKAGE_LLVM_ARCH_SUPPORTS
so that it isn't disabled on architectures where LLVM is anyway not
supported.]

This commit adds the following options to the pkg-stats-new script:
-n, to specify a number of packages to parse instead of all packages
-p, to specify a list of packages (comma-separated) to parse instead
of all packages
These options are basically only useful when debugging/developing
this script, but they are very useful, because the script is rather
slow to run completely with all 2000+ packages, especially once
upstream versions will be fetched from release-monitoring.org.

This commit adds a new version of the pkg-stats script, rewritten in
Python. It is for now implemented in a separate file called,
pkg-stats-new, in order to make the diff easily readable. A future
commit will rename it to pkg-stats.
Compared to the existing shell-based pkg-stats script, the
functionality and output is basically the same. The main difference is
that the output no longer goes to stdout, but to the file passed as
argument using the -o option. This allows stdout to be used for more
debugging related information.
The way the script works is that a first function get_pkglist()
returns a list of Package objects. Then, the function
package_init_make_info() uses 'make printvars' to gather information
about all packages, stored as class variables in the Package
class. Then, we iterate over all packages, and use various methods of
the Package class to retrieve all details about the package:
infrastructure, presence of hash file, presence of license
information, etc.
calculate_stats() then calculates global statistics (how packages have
license information, how packages have a hash file, etc.). Finally,
dump_html() produces the HTML output, using a number of sub-functions.
One improvement over the shell-based version is that we can use
regexps to exclude some .mk files. Thanks to this, we can exclude all
linux-ext-*.mk files, avoiding incorrect matches.

When the BR2_DL_DIR is a mountpoint (presumably shared between various
machine, or mounted from the local host when running in a VM), it is
possible that it does not support hardlinks (e.g. samba, or the VMWare
VMFS, etc...).
If the hardlink fails, fallback to copying the file. As a last resort,
if that also fails, eventually fallback to doing the download.
Note: this means that the dl-wrapper is no longer atomic-safe: the code
suffers of a TOCTTOU condition: the file may be created in-between the
check and the moment we try to ln/cp it. Fortunately, the dl-wrapper is
now run under an flock, so we're still safe. If we eventually go for a
more fine-grained implementation, we'll have to be careful then.

According to hostapd's defconfig file, ACS is currently only supported
through the nl80211 driver. Search through the source code also confirms
that ACS machinery is present in the nl80211 driver only.
Although hostapd can be built with ACS enabled and nl80211 disabled, an
attempt to use ACS with other drivers by setting a wireless channel to 0
results in a runtime failure (driver doesn't accept this value). So we
might save a user from selecting a meaningless combination by making ACS
dependent on nl80211.

Now we keep the git clone that we download and generates our tarball
from there.
The main goal here is that if you change the version of a package (say
Linux), instead of cloning all over again, you will simply 'git fetch'
from the repo the missing objects, then generates the tarball again.
This should speed the 'source' part of the build significantly.
The drawback is that the DL_DIR will grow much larger; but time is more
important than disk space nowadays.
