Summary:
This string parameter is passed to -fuse-ld when linking. It can be
an absolute path to your custom linker, otherwise clang will look for
`ld.{name}`.

Add an explicit LLVM_ENABLE_DIA_SDK option to control building support
for DIA SDK-based debugging. Control its value to match whether DIA SDK
support was found and expose it in LLVMConfig (alike LLVM_ENABLE_ZLIB).
Its value is needed for LLDB to determine whether to run tests requiring
DIA support. Currently it is obtained from llvm/Config/config.h;
however, this file is not available for standalone builds. Following
this change, LLDB will be modified to use the value from LLVMConfig.

Summary:
This allows to have clang and llvm and the other subprojects
side-by-side instead of nested. This can be used with the monorepo or
multiple repos.
It will help having a single set of sources checked out but allows to
have a build directory with llvm and another one with llvm+clang.
Basically it abstracts LLVM_EXTERNAL_xxxx_SOURCE_DIR making it more
convenient by adopting a convention.

Support overriding the Doxygen & OCamldoc install directories,
and provide a more FHS-compliant defaults for both of them. This extends
r282240 that added this override for Sphinx-built documentation.
LLVM_INSTALL_DOXYGEN_HTML_DIR and LLVM_INSTALL_OCAMLDOC_HTML_DIR are
added, to control the location where Doxygen-generated and
OCamldoc-generated HTML docs are installed appropriately. They both
specify CMake-style install paths, and therefore can either by relative
to the install prefix or absolute.
The new defaults are subdirectories of share/doc/llvm, and replace
the previous directories of 'docs/html' and 'docs/ocaml/html' that
resulted in creating invalid '/usr/docs' that furthermore lacked proper
namespacing for the LLVM package. The new defaults are consistent with
the ones used for Sphinx HTML documentation, differing only in the last
component. Since the 'html' subdirectory is already used for Sphinx
docs, the 'doxygen-html' and 'ocaml-html' directories are used instead.

This is a partial revert of r280013. Brad King pointed out these variable names are matching CMake conventions, so we should preserve them.
I've also added a direct mapping of the LLVM_*_DIR variables which we need to make projects support building in and out of tree.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@280380 91177308-0d34-0410-b5e6-96231b3b80d8
With the runtimes build we're trying to use LLVMConfig.cmake as a way of providing LLVM_* variables that are needed to behave as if the project is building in tree. To make this work we need to rename two variables by dropping the "S" from the end. This makes the variables match the in-tree names.
This renames:
LLVM_INCLUDE_DIRS -> LLVM_INCLUDE_DIR
LLVM_LIBRARY_DIRS -> LLVM_LIBRARY_DIR
The versions ending in S are not used in-tree anywhere. This also cleans up LLVM_LIBRARY_DIR being set to the same value with and without the "S".

The new option makes it possible to build external projects as part of
the llvm build without copying (or symlinking) then into llvm/tool with
specifying a few additional cmake variables.
Example usage (2 additional project called foo and bar):
-DLLVM_EXTERNAL_PROJECTS="Foo;Bar"
-DLLVM_EXTERNAL_FOO_SOURCE_DIR=/src/foo
-DLLVM_EXTERNAL_BAR_SOURCE_DIR=/src/bar
Note: This is the extension of the approach we already support for
clang/lldb/poly with adding an option to specify additional supported
projects.

Mehdi suggested in a review of r259766 that it's also useful to easily
set the type of LTO. Augment the cmake variable to support that.

This is the right location for platform-specific files.
On some distributions (e. g. Exherbo), a package can be installed for several
architectures in parallel, but the architecture-independent files are shared.
Therefore, we must not install architecture-dependent files (like the CMake
config and export files) to share/.

This adds -DLLVM_ENABLE_LTO, rather than forcing people to manually
add -flto to the various _FLAGS variables.

CMake v3.2 or newer is necessary to get interactive output when running
Lit via Ninja. Otherwise Ninja will buffer Lit's output, which makes
for a crummy experience -- you can't tell if your tests are hung!

- Fix some grammatical and typographical errors.
- Try to improve upon some awkward/nonstandard phrasings.
- Expand slightly the treatment of how you specify arguments to cmake.
- Update the list of possible LLVM_BUILD_TESTS and state where to find the
definitive list.
- Correct the name of llvm-tblgen.
- Expand slightly the treatment of several build options, including
LLVM_LIT_TOOLS_DIR, LLVM_ENABLE_FFI, and LLVM_EXTERNAL_project_SOURCE_DIR.

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.
