Chandler Carruth 7d58776fad [cmake] Teach the llvm-config program to respect LLVM_LIBDIR_SUFFIX.
For this to work, we have to encode it in the build variables and use it
from llvm-config.cpp. I've tried to do this reasonably cleanly, but the
code for llvm-config.cpp is pretty strange. However, with this,
llvm-config stops giving the wrong answer when using LLVM_LIBDIR_SUFFIX.

Note that the configure+make build just sets this to an empty string as
that build system has zero support for multilib of any form. I'm not
planning to add support there either, but this should leave a path for
anyone that wanted to.

Chris Bieneman 5007741d68 Enabling LLVM & Clang to be cross-compiled using CMake from a single configuration command line
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.

Reid Kleckner 65fc0e2c00 Change llvm-config --ldflags to report ${CMAKE_CXX_LINK_FLAGS}
Should fix PR19526.

When Oscar added this code in the intial CMake build system port, he had
a TODO saying that ${CMAKE_SHARED_LINKER_FLAGS} was probably wrong.  I
agree.  I'm using ${CMAKE_CXX_LINK_FLAGS} to point LLVM at my custom
installation of gcc 4.recent, so that seems more correct.  With this
change, I can build creduce against an installed clang, and it picks up
the write flags from --ldflags.

Richard Osborne 49ae117757 Don't emit a blank line when running llvm-config --system-libs.
Summary:
Previously llvm-config --system-libs would print something like:

$ llvm-config --system-libs

-lz -ltinfo -lrt -ldl -lm

Now we don't emit blank line. Functionality is unchanged otherwise, in
particular llvm-config --libs --system-libs still emits the LLVM libraries
and the system libraries on different lines.

NAKAMURA Takumi af2c1130ee Simplify linking to system libraries
The LLVMSupport library implementation consolidates all dependencies on
system libraries.  Move the logic gathering system libraries out of
'cmake/modules/LLVM-Config.cmake' and into 'lib/Support/CMakeLists.txt'.
Use the target_link_libraries() command there to tell CMake about the
link dependencies of the LLVMSupport implementation.  CMake will
automatically propagate this to all targets that link LLVMSupport
directly or indirectly.

We still need to build knowledge of system library dependencies into
'llvm-config'.  Store the list of libraries needed in a property on
LLVMSupport and teach 'tools/llvm-config/CMakeLists.txt' to retrieve it
from there.

Drop all calls to 'link_system_libs' and 'get_system_libs' from our
CMake code.  Replace their implementations with a warning that explains
the calls are no longer necessary.  Also drop from 'LLVMConfig.cmake'
the HAVE_* and related variables that were published there only to allow
'get_system_libs' to run outside our build process.

  $ bin/llvm-config --libs object

It was previously not being built on Windows because the cmake file relied
on a sed script to generate a .in file that llvm-config needs.

By using cmake's configure_file function, we can get rid off the sed hack,
and also have this work on Windows.

Jordan Rose 2998d25a6e Revert "Add --program-prefix support to build"
The Apple buildbots are set up to pass --target to configure for both
cross- and non-cross-compile builds, and the standard autoconf response
to this is to set the program prefix to '<target>-'. Until we can figure
out the proper way to handle this (don't pass --target? pass an explicit
--program-prefix=""? don't auto-populate program_prefix with target_alias?)
it's more important to keep the buildbots running.

This reverts r164633 / ba48ceb1a3802e20e781ef04ea2573ffae2ac414.

Bob Wilson 7789aae96d Do not install llvm-config-host for cross-builds of clang. rdar://11317847
My previous change to install llvm-config-host for cross-builds resulted
in that file being installed even when the normal llvm-config was not
installed, e.g., when building the install-clang target.  Daniel suggested
this alternative, which solves the immediate problem and also avoids the gunk
in the top-level makefile.

Peter Collingbourne 16dab1bada Have llvm-config --cppflags print correct flags when in CMake build directory
Previously, if invoked from a CMake build directory, 'llvm-config
--cppflags' and friends would only print a -I flag for the build
directory's header search path, because it would assume that it was
already installed, not recognising its parent directory as being the
build directory.  Teach llvm-config about CMake build directories
so that it prints a -I for both the source and build directory's
search paths.

Chandler Carruth 9d7feab3e0 Rewrite the CMake build to use explicit dependencies between libraries,
specified in the same file that the library itself is created. This is
more idiomatic for CMake builds, and also allows us to correctly specify
dependencies that are missed due to bugs in the GenLibDeps perl script,
or change from compiler to compiler. On Linux, this returns CMake to
a place where it can relably rebuild several targets of LLVM.

I have tried not to change the dependencies from the ones in the current
auto-generated file. The only places I've really diverged are in places
where I was seeing link failures, and added a dependency. The goal of
this patch is not to start changing the dependencies, merely to move
them into the correct location, and an explicit form that we can control
and change when necessary.

This also removes a serialization point in the build because we don't
have to scan all the libraries before we begin building various tools.
We no longer have a step of the build that regenerates a file inside the
source tree. A few other associated cleanups fall out of this.

This isn't really finished yet though. After talking to dgregor he urged
switching to a single CMake macro to construct libraries with both
sources and dependencies in the arguments. Migrating from the two macros
to that style will be a follow-up patch.

Also, llvm-config is still generated with GenLibDeps.pl, which means it
still has slightly buggy dependencies. The internal CMake
'llvm-config-like' macro uses the correct explicitly specified
dependencies however. A future patch will switch llvm-config generation
(when using CMake) to be based on these deps as well.

This may well break Windows. I'm getting a machine set up now to dig
into any failures there. If anyone can chime in with problems they see
or ideas of how to solve them for Windows, much appreciated.
