As we discussed on the mailing list, using $(<pkg>_NAME) when defining
CPE ID variables feels a bit odd and needlessly complicated. Just use

LLVM builds bindings for other languages such as Go and OCaml when the
appropriate dependencies can be found. We currently don't support
building these bindings in Buildroot, as they're currently unused by any
package.
Building these bindings was originally disabled by overriding the
dependencies with values indicating that they were not found.
Newer versions of LLVM no longer disable the OCaml bindings when overriding
OCAMLFIND. Consequently, the build process attempts to install the bindings
to the default location on the host of /usr/lib/ocaml/llvm, causing a
permissions error and build failure.
Additionally, LLVM has since added the variable LLVM_ENABLE_BINDINGS to
control whether bindings are enabled, so we override that to disable the
bindings.

Allow to build LLVM with run-time type information as this feature is
needed (for example) by mesa3d's Gallium Nouveau driver or the Clover
OpenCL state tracker when llvm support is enabled in mesa3d.
While we only care about RTTI support in the target, we also need to
enable it in the host LLVM, so that llvm-config gives the proper
result.

While building llvm for the target (x86_64), the build failed due to
path poisoning (-I/usr/include/libxml2) while building NATIVE tools
(i.e for the host). The llvm package tries to build a tool for the host
with the cross-compiler which doesn't work when the paranoid toolchain
wrapper (BR2_COMPILER_PARANOID_UNSAFE_PATH) is enabled.
We know that llvm (target) needs llvm-tablegen and llvm-config built by
host-llvm, but only LLVM_TABLEGEN is provided by llvm.mk. Adding
LLVM_CONFIG_PATH=$(HOST_DIR)/bin/llvm-config for llvm (target)
fixes the path poisoining issue since llvm doesn't build the NATIVE
variant.

AddLLVM.cmake adds $ORIGIN/../lib to the RPATH of llvm binaries. This
causes a problem when llvm-config built for the host, installed in
STAGING_DIR, is executed under the following conditions:
* Target architecture same as host architecture (normally x86_64)
* Target's libc different from host's libc (normally glibc)
llvm-config will try to link with the target's libc, resulting in:
./llvm-config: error while loading shared libraries: libc.so.0: cannot open shared object file: No such file or directory.
To avoid this, we simply add pass
-DCMAKE_INSTALL_RPATH="$(HOST_DIR)/lib" in HOST_LLVM_CONF_OPTS.

LLVM uses std::shared_future, which until gcc 7.x isn't available on
architectures that don't provide lock-free atomics, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64735.
Buildroot already has a BR2_TOOLCHAIN_HAS_GCC_BUG_64735 option to
handle such a case, so simply add this new dependency to LLVM. It will
make sure LLVM doesn't get built on ARMv5 platforms using a gcc older
than 7.x.

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
