There were two main problems:
* The 'nativecodegen' pseudo-component was unconditionally adding
${native_tgt}CodeGen even though it conditionally added ${native_tgt}Info and
${native_tgt}Desc. This has been fixed by making ${native_tgt}CodeGen
conditional too
* The 'all' pseudo-component was causing library names like LLVMLLVMDemangle as
the expansion was to a library name and not a component. There doesn't seem to
be a list of available components anywhere so this has been fixed by moving the
expansion of 'all' back where it was before. This manifested in different ways
on different builders but it was the same root cause
llvm-svn: 366622
Some targets are missing LLVMDemangle, one is adding the LLVM prefix twice, and two
are hitting the very error this patch fixes for my target. Reverting while I work
through the reports.
llvm-svn: 366615
Summary:
If you use pseudo-targets like AllTargetsCodeGens in LLVM_DYLIB_COMPONENTS
then a test will fail because `./bin/llvm-config --shared-mode` can't
handle these targets. We can fix this by expanding them before embedding
the string into llvm-config

Instead of duplicating functionality for building native versions of
tblgen and llvm-config, add a function to set up a native tool build.
This will also be used for llvm-nm in a follow-up.
This should be NFC for tblgen, besides the slightly different COMMENT
for the custom command (it'll display the tablegen target name instead
of always saying TableGen). For the native llvm-config, it's a behavior
change in that we'll use llvm_ExternalProject_BuildCmd instead of
constructing the build command manually, always build in Release, and
reference the correct binary path for multi-config generators. I believe
all of these changes to be bug fixes.

CMake variable LLVM_DEFINITIONS collects preprocessor definitions provided
for host compiler that builds llvm components. A function
add_llvm_definitions was introduced in AddLLVMDefinitions.cmake to keep
track of these definitions and was intended to be a replacement for CMake
command add_definitions. Actually in many cases add_definitions is still
used and the content of LLVM_DEFINITIONS is not actual now. On the other
hand the current version of CMake allows getting set of definitions in a
more convenient way. This fix implements evaluation of the variable by
reading corresponding cmake property.

Following the similar change to lit configuration, ensure that all CMake
booleans are canonicalized to 0/1 when being passed to llvm-config. This
fixes the incorrect interpretation of values when user passes another
value than the ON/OFF, and simplifies the code by removing unnecessary
string matching.
Furthermore, the code for --has-rtti and --has-global-isel has been
modified to print consistent values indepdently of the boolean used by
passed by the user to CMake. Sadly, the code already implicitly used
different values for the two (YES/NO for --has-rtti, ON/OFF for
--has-global-isel).
Include tests for all booleans and multi-value options in llvm-config.

This sets USES_TERMINAL for the native llvm-config build, so that it
doesn't run at the same time as builds of other native tools (namely,
tablegen). Without this, if you're very unlucky with the timing it's
possible to be relinking libSupport as one of the tools is linking,
causing a spurious failure.
The tablegen build adopted USES_TERMINAL for this same reason in
r280748.
llvm-svn: 290271
Previously LLVM_HAS_GLOBAL_ISEL would directly get the value of
LLVM_BUILD_GLOBAL_ISEL. This could be any integer value and not just ON
and OFF. The problem is that lit.cfg was checking for ON to define that
global-isel was supported, thus if we were setting
LLVM_BUILD_GLOBAL_ISEL with an integer value, say 1, this test would
fail whereas we do build global-isel and want to test it.

Summary:
This is a re-commit of r257003, which was reverted,
along with the fixes from http://reviews.llvm.org/D15986.
r252532 added support for reporting the monolithic library
when LLVM_BUILD_LLVM_DYLIB is used. This would only be done
if the individual components were not found, and the dynamic
library is found.
This diff extends this as follows:
- If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared
library, even if all component libraries exist.
- Two flags, --link-shared and --link-static are introduced
to provide explicit guidance. If --link-shared is passed
and the shared library does not exist, an error results.
Additionally, changed the expected shared library names from
(e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an
installation (and then only in CMake builds I think?), and not
in the build tree; this breaks usage of llvm-config during
builds, e.g. by llvm-go.

Summary:
This patch does a couple of things:
- Adds a new argument `--shared-mode` which accepts a list of components and prints whether or not the provided components need to be linked statically or shared.
- Fixes `--libnames` when CMake BUILD_SHARED_LIBS is used.
- Fixes `--libnames`, `--libs`, and `--libfiles` for dylib when static components aren't installed.
- Fixes `--libnames`, `--libs`, `--libfiles`, and `--components` to use LLVM_DYLIB_COMPONENTS as the component manifest for dylib linking.
- Uses the host platform's usual convention for filename extensions and such, instead of always defaulting to Unix-izms.
Because I don't own a Mac, I am not able to test the Mac platform dependent stuff locally. If someone would be willing to run a build for me on their machine (unless there's a better option), I'd appreciate it.

Summary:
This prints NO if LLVM was built with -fno-rtti or an equivalent flag
and YES otherwise. The reasons to add -has-rtti rather than adding -fno-rtti
to --cxxflags are:
1. Building LLVM with -fno-rtti does not always mean that client
applications need this flag.
2. Some compilers have a different flag for disabling rtti, and the
compiler being used to build LLVM may not be the compiler being used to
build the application.

It seems I was wrong thinking `autoconf`/`make` only installed shared libraries if configured with `--enable-shared`, even if `--disable-static` is present. I'll re-address with a followup patch.
This reverts commit r243297 for causing PR#24154.
llvm-svn: 244108
Summary:
When LLVM is configured to build shared libraries, CMake builds each component as it's own shared object, while autoconfig/make builds them statically and then links them all together to create a single shared object. This change adds compile time config flags to `llvm-config` so it can know whether LLVM's components are separated or not and act accordingly.
This fixes `llvm-config` instead of fixing the makefiles to behave like CMake because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.
This change only affects `llvm-config` from builds that use autoconfig/make.

* put most of the cross-compiling support into a function llvm_create_cross_target_internal.
* when CrossCompile is included it still generates a NATIVE target.
* llvm_create_cross_target function takes a target_name which should match a toolchain.
* llvm_create_cross_target can now be used to target more than one cross-compilation target.
llvm-svn: 232067
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.

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.

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.

to force it to build after all library targets so it has complete
dependency information. This should fix broken 'make install' with

This is a partial revert of r143540, but it doesn't revert the most

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.
llvm-svn: 143171
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.
