Summary:
This patch adds a new internal variable
LLVM_RUNTIME_DISTRIBUTION_COMPONENTS which specifies distribution
components that are part of runtime projects, and thus should be exposed
from runtime configuraitons up into the top-level CMake configurations.
This is required for allowing runtime components to be included in
LLVM_DISTRIBUTION_COMPONENTS because we verify that the build and
install targets exist for every component specified for the
distribution.
Without this patch runtimes and builtins can only be included in
distributions in whole, not by component.

It used to symlink dsymutil to llvm-dsymutil, but after r327790 llvm's dsymutil
binary is now called dsymutil without prefix.
r327792 then reversed the direction of the symlink if
LLVM_INSTALL_CCTOOLS_SYMLINKS was set, but that looks like a buildfix and not
like something anyone should need.

Enables making DataTypes.h a regular header instead of a .h.cmake file and

Compiler.h is used by Demangle (which Support depends on) - so sink it
into Demangle to avoid a circular dependency
DataTypes.h is used by llvm-c (which Support depends on) - so sink it
into llvm-c.
DataTypes.h could probably be fixed the other way - making llvm-c depend
on Support instead of Support depending on llvm-c - if anyone feels
that's the better option, happy to work with them on that.
I /think/ this'll address the layering issues that previous attempts to
commit this have triggered in the Modules buildbot, but I haven't been
able to reproduce that build so can't say for sure. If anyone's having
trouble with this - it might be worth taking a look to see if there's a
quick fix/something small I missed rather than revert, but no worries.

Support depends on llvm-c (a few typedefs, macros, etc - Types.h,
Disassembler.h, and TargetMachine.h.
This could be done the other way - those macros/typedefs/etc could be
moved into Support and used from llvm-c instead. If someone feels that's
a better direction to go, happy to discuss it/try it out/etc.

Add a `LLVM_INSTALL_CCTOOLS_SYMLINKS` to mirror
`LLVM_INSTALL_BINUTILS_SYMLINKS`. For now, this allows us to create

default, but the user can enable it.

Newer versions of CMake (I'm on 3.10, but I believe 3.9 behaves the same
way) attempt to query the system for information about the VS 2017
install. Unfortunately, this query fails on non-Windows systems:
cmake_host_system_information does not recognize <key> VS_15_DIR
CMake isn't going to find these system libraries on non-Windows anyway
(and we were previously silencing the resultant warnings in our
cross-compilation toolchain), so it makes sense to just omit the
attempted installation entirely on non-Windows.

llvm-svn: 320111
CMake's generated installation scripts support `CMAKE_INSTALL_DO_STRIP`
to enable stripping the installed binaries. LLVM's build system doesn't
expose this option to the `install-` targets, but it's useful in
conjunction with `install-distribution`.
Add a new function to create the install targets, which creates both the
regular install target and a second install target that strips during
installation. Change the creation of all installation targets to use
this new function. Stripping doesn't make a whole lot of sense for some
installation targets (e.g. the LLVM headers), but consistency doesn't
hurt.
I'll make other repositories (e.g. clang, compiler-rt) use this in a
follow-up, and then add an `install-distribution-stripped` target to
actually accomplish the end goal of creating a stripped distribution. I
don't want to do that step yet because the creation of that target would
depend on the presence of the `install-*-stripped` target for each
distribution component, and the distribution components from other
repositories will be missing that target right now.

This was reverted due to the tests being run twice on some
build bots. Each run had a slightly different configuration
due to the way in which it was being invoked. This fixes
the problem (albeit in a somewhat hacky way). Hopefully in
the future we can get rid of the workflow of running
debuginfo-tests as part of clang, and then this hack can
go away.
llvm-svn: 318697
This is still broken because it causes certain tests to be
run twice with slightly different configurations, which is
wrong in some cases.
You can observe this by running:
ninja -nv check-all | grep debuginfo-tests
And seeing that it passes clang/test and clang/test/debuginfo-tests
to lit, which causes it to run debuginfo-tests twice. The fix is
going to involve either:
a) figuring out that we're running in this "deprecated" configuration,
and then deleting the clang/test/debuginfo-tests path, which should
cause it to behave identically to before, or:
b) make lit smart enough that it doesn't descend into a sub-suite if
that sub-suite already has a lit.cfg file.
llvm-svn: 318486
This was reverted due to some failures on specific darwin buildbots,
the issue being that the new lit configuration was not setting the
SDKROOT environment variable. We've tested a fix locally and confirmed
that it works, so this patch resubmits everything with the fix
applied.
llvm-svn: 318435
Summary:
This patch adds a LLVM_ENABLE_GISEL_COV which, like LLVM_ENABLE_DAGISEL_COV,
causes TableGen to instrument the generated table to collect rule coverage
information. However, LLVM_ENABLE_GISEL_COV goes a bit further than
LLVM_ENABLE_DAGISEL_COV. The information is written to files
(${CMAKE_BINARY_DIR}/gisel-coverage-* by default). These files can then be
concatenated into ${LLVM_GISEL_COV_PREFIX}-all after which TableGen will
read this information and use it to emit warnings about untested rules.
This technique could also be used by SelectionDAG and can be further
extended to detect hot rules and give them priority over colder rules.
Usage:
* Enable LLVM_ENABLE_GISEL_COV in CMake
* Build the compiler and run some tests
* cat gisel-coverage-[0-9]* > gisel-coverage-all
* Delete lib/Target/*/*GenGlobalISel.inc*
* Build the compiler
Known issues:
* ${LLVM_GISEL_COV_PREFIX}-all must be generated as a manual
step due to a lack of a portable 'cat' command. It should be the
concatenation of all ${LLVM_GISEL_COV_PREFIX}-[0-9]* files.
* There's no mechanism to discard coverage information when the ruleset
changes

Previously, debuginfo-tests was expected to be checked out into
clang/test and then the tests would automatically run as part of
check-clang. This is not a standard workflow for handling
external projects, and it brings with it some serious drawbacks
such as the inability to depend on things other than clang, which
we will need going forward.
The goal of this patch is to migrate towards a more standard
workflow. To ease the transition for build bot maintainers,
this patch tries not to break the existing workflow, but instead
simply deprecate it to give maintainers a chance to update
the build infrastructure.

The LLVM tools can be used as a replacement for binutils, in which case
it's convenient to create symlinks with the binutils names. Add support
for these symlinks in the build system. As with any other llvm tool
symlinks, the user can limit the installed symlinks by only adding the
desired ones to `LLVM_TOOLCHAIN_TOOLS`.

LLVM now requires a minimum of cmake 3.4.3, and all the policies
currently being set are present in that cmake version, so the
conditionals will always be true and are therefore unnecessary. The
movation is that the conditionals can give the false impression that the
policy settings are optional, whereas for example it's necessary to set
CMP0056 in order for `check_linker_flags` to operate correctly after
r316972. Inline the project version and language setting in the process.

It's possible for multiple distribution components to have missing

llvm-svn: 317148
`check_linker_flags` currently sets the *compiler* flags (via
`CMAKE_REQUIRED_FLAGS`), and thus implicitly relies on cmake's default
behavior of passing the compiler flags to the linker. This breaks when
cmake's build rules have been altered to not pollute the link line with
compiler flags (which can be desirable for build cleanliness). Instead,
set `CMAKE_EXE_LINKER_FLAGS` explicitly and use `CMP0056` to ensure the
linker flags are passed along. Additionally, since we're inside a
function, we can just alter the variable directly (as the alteration
will be limited to the scope of the function) rather than saving and
restoring the old value.

LLVM checks if it is performing an in-source build and then stop the
build. However, this check is also triggered if LLVM is being build as
part of a parent project, which prevents the parent project itself from
using in-source builds. For example, CMake allows a parent project to
specify the output of its subproject:
add_subdirectory(llvm llvm_build)
This tells CMake to conduct an out-tree build of LLVM, which without
this patch will still fails because what is being tested is the parent
project, not LLVM. This is fixed by using the "CURRENT" variable, which
is only concerned by the CMakeLists that is actually bein processed at
the moment.
Tests:
Ran `make check-llvm`.

We add /usr/local/include to the include directory list for some BSD

Summary:
*In-source builds* of LLVM, in which a user invokes `cmake` from within the
LLVM source directory, or invokes `cmake -B/path/to/source/dir/of/llvm`,
are explicitly checked for and disallowed by LLVM's `CMakeLists.txt`.
*In-tree builds*, on the other hand, refer to when the source directories
of projects such as Clang are nested within the `llvm/tools` source
directory. These are not disallowed, and are in fact a common way of
building LLVM and Clang.
Revise the comment to match the logic underneath it: it checks for an
"in-source build", not an "in-tree build".
