Re-landing r242059 which re-landed r241621... I'm really bad at this.
Summary (r242059):
This change re-lands r241621, with an additional fix that was required to allow tool sources to live outside the llvm checkout. It also no longer renames LLVM_EXTERNAL_*_SOURCE_DIR. This change was reverted in r241663, because it renamed several variables of the format LLVM_EXTERNAL_*_* to LLVM_TOOL_*_*.
Summary (r241621):
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:
* factored out canonicalizing tool names from paths to CMake variables * removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

LLVM_EXTERNAL_*_SOURCE_DIR is reset as PATH with set(CACHE PATH).

add_llvm_external_project puts LLVM_EXTERNAL_${nameUPPER}_SOURCE_DIR into the cache even if it is just the in-tree default path. This causes all sorts of oddness, and makes it so that I can't change the behavior of this variable.
This patch never puts LLVM_EXTERNAL_${nameUPPER}_SOURCE_DIR into the cache. It will only end up in the cache if it is specified on the command line, which is the correct behavior.
There is also a temporary change to remove non-default values from the cache if they are already present. This should have the impact of cleaning out unncecissary values from the caches on the buildbots and people's local build directories. This part of the change is marked with a TODO and can be removed in a few days.

prevented a binary installation from being relocated to a different

Package maintainers who choose to modify the install location of the

In CMake dependencies can be filenames or targets, and targets can't be filenames. The Ninja generator handles filename dependencies because it generates targets for every output file from a command. For example:
add_custom_command(OUTPUT foo.txt COMMAND touch foo.txt)
With the Ninja generator this generates a target foo.txt, but with the Makefile generator it doesn't. This is probably because Ninja explicitly requires these hard dependency ties, and Make just behaves oddly in general.
To fix this we need to make the tablegen actions depend on a target rather than a filename.

This adds the following targets to cmake. These can be used to build and link only specific parts of a backend, instead of having to link the whole backend.

This means it can only take one parameter from the set of RUNTIME, LIBRARY, or ARCHIVE. If you set more than one of these it seems to gobble up the extra arguments and ignore the COMPONENT argument.

Summary:
This patch is an attempt at making `DenseMapIterator`s "fail-fast".
Fail-fast iterators that have been invalidated due to insertion into
the host `DenseMap` deterministically trip an assert (in debug mode)
on access, instead of non-deterministically hitting memory corruption
issues.
Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are
predicated on `LLVM_ENABLE_ABI_BREAKING_CHECKS`.
`LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with
`LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake /
autoconf build system.

CMake 3.2 changed the Ninja generator to list both the .exe and .lib

Introduce -mllvm -sanitizer-coverage-8bit-counters=1
which adds imprecise thread-unfriendly 8-bit coverage counters.
The run-time library maps these 8-bit counters to 8-bit bitsets in the same way
AFL (http://lcamtuf.coredump.cx/afl/technical_details.txt) does:
counter values are divided into 8 ranges and based on the counter
value one of the bits in the bitset is set.
The AFL ranges are used here: 1, 2, 3, 4-7, 8-15, 16-31, 32-127, 128+.
These counters provide a search heuristic for single-threaded
coverage-guided fuzzers, we do not expect them to be useful for other purposes.
Depending on the value of -fsanitize-coverage=[123] flag,
these counters will be added to the function entry blocks (=1),
every basic block (=2), or every edge (=3).
Use these counters as an optional search heuristic in the Fuzzer library.
Add a test where this heuristic is critical.

Minimum required version found by Michael Edwards!
llvm-svn: 229584
Since header files are not compilation units, CMake does not require
you to specify them in the CMakeLists.txt file. As a result, unless a
header file is explicitly added, CMake won't know about it, and when
generating IDE-based projects, CMake won't put the header files into
the IDE project. LLVM currently tries to deal with this in two ways:
1) It looks for all .h files that are in the project directory, and
adds those.
2) llvm_add_library() understands the ADDITIONAL_HEADERS argument,
which allows one to list an arbitrary list of headers.
This patch takes things one step further. It adds the ability for
llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which
will specify a list of folders which CMake will glob for header files.
Furthermore, it will glob not only for .h files, but also for .inc
files.
Included in this CL is an update to one of the existing users of
ADDITIONAL_HEADERS to use this new argument instead, to serve as an
illustration of how this cleans up the CMake.
The big advantage of this new approach is that until now, there was no
way for the IDE projects to locate the header files that are in the
include tree. In other words, if you are in, for example,
lib/DebugInfo/DWARF, the corresponding includes for this project will
be located under include/llvm/DebugInfo/DWARF. Now, in the
CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write:
ADDITIONAL_HEADER_DIRS
../../include/llvm/DebugInfo/DWARF
as an argument to llvm_add_library(), and all header files will get
added to the IDE project.

error: unable to load plugin 'lib/PrintFunctionNames.so': 'lib/PrintFunctionNames.so: undefined symbol: _ZN5clang15PluginASTAction6anchorEv'
I think we should inspect linker's version or behavior to introduce --gc-sections for --export-dynamic.

This code is based on the existing LLVM Go bindings project hosted at:
https://github.com/go-llvm/llvm

their changes under the LLVM license and submit them to the LLVM project.

lldb sets the variable SHARED_LIBRARY to 1, which breaks this conditional,
because older versions of CMake interpret
if ("${t}" STREQUAL "SHARED_LIBRARY")
as meaning
if ("${t}" STREQUAL "1")
in this case. Change the conditional so it does the right thing with both old
and new CMakes.

This fixes the generation of broken LLVMExports.cmake file by
the Autoconf/Makefile build system when --enable-shared is passed to
configure.
When --enable_shared is passed the Makefile.rules does not set the
LLVMConfigLibs variable which cmake/modules/Makefile previously relied
on. Now it runs the llvm-config command itself to get the library names.
This still isn't perfect because the generated LLVM targets refer to the
static libraries and not the shared library but that is much larger
problem to fix.

The basic idea is similar to the existing cross compilation support. A directory must be configured to build host versions of tablegen tools and llvm-config. This directory can be user provided (and configured), or it can be created during the build. During a build the native build directory will be configured and built to supply the tablegen tools used during the build. A user could also explicitly provide the tablegen executables to run on the CMake command line.

This test was testing nothing, as only -Werror was ever
being added to the compiler flags.
You can see the final nitty-gritty compiler invocation in
CMakeFiles/CMakeOutput.log (for successful tests) and
CMakeFiles/CMakeError.log (for failed tests).

clang has only been smart enough not to trigger -Wnon-virtual-dtor
warnings on final classes since r208449 (in clang 3.5). Building
with older versions is extremely noisy, so disable the warning
on those compilers.
