Prospectively revert to get one of the many build configurations back working
(presumably the side-by-side+modular CMake config).
This reverts commit r212997.

We probably just need to touch LLVM's configure this time to work around the
totally inadequate Makefile build server integration.
This reverts commit r210314.
llvm-svn: 210320
This will unbreak clang vendor builds as a follow-up to r210238, now that we
can't poke into LLVM's private config.h (nor should the string be exposed by
llvm-config.h).
This hopefully removes for good the last include of LLVM's config.h.

target_link_libraries(INTERFACE) doesn't bring inter-target dependencies in add_library,
although final targets have dependencies to whole dependent libraries.
It makes most libraries can be built in parallel.
target_link_libraries(PRIVATE) is used to shaared library.
Each dependent library is linked to the target.so, and its user will not see its grandchildren.
For example,
- libclang.so has sufficient libclang*.a(s).
- c-index-test requires just only libclang.so.
FIXME: lld is tweaked minimally. Adding INTERFACE in each library would be better thing.
llvm-svn: 202241
For now, use both keywords, INTERFACE and PRIVATE via the variable,
- ${cmake_2_8_12_INTERFACE}
- ${cmake_2_8_12_PRIVATE}
They could be cleaned up when we introduce 2.8.12.
llvm-svn: 202239
This does;
- clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
- List of targets is added to LLVM_COMMON_DEPENDS.
- all clang libraries and targets depend on generated headers.
You might wonder this would be regression, but in fact, this is little loss.
- Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
- clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
- Each library's dependencies to tblgen'd files might vary along headers' structure.
It made hard to track and update *really optimal* dependencies.
Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

The CMake install(DIRECTORY) command documents that it sets permissions
on directories it is asked to install. Since the <prefix>/include
directory may not be exclusive to the LLVM/Clang installation, we should
not ask CMake to manage permissions of that directory for us. Instead,
give only our own include/clang and include/clang-c subdirectories to
the install(DIRECTORY) command.
Fixes PR4500. Patch by Brad King.

so bump the minimum version in the standalone Clang CMake project as
well.
As I mentioned on the LLVM commit version of this, if this causes any
trouble for folks, just let me know. I'm trying to avoid re-implementing
functionality in CMake, but I will if there are problems using the newer
versions.

It was too late to set BUG_REPORT_URL after configure_file(config.h).
BUG_REPORT_URL in config.h.cmake would be updated at 2nd run of cmake.
It caused many recompilations.
FYI, configure handles BUG_REPORT_URL in llvm side.

Convert CMake CLANG_BUILD_EXAMPLES to a boolean value for consumption by
Python, otherwise the raw config string gets passed through which may not be
0/1.
The if/else matches the technique used to solve the problem in LLVM's own
CMakeLists.txt.
llvm-svn: 198750
Somehow the entire plugin infrastructure went wholly untested until now.
The only plugins available for use in testing are the examples, so plugin tests
will only be run if CLANG_BUILD_EXAMPLES is enabled in the build.
(The examples should really be enabled by default, not just to aid testing but
also to prevent bitrot in some key user-facing code. I'll propose that
shortly.)
Requires supporting changes in LLVM r198746.
llvm-svn: 198747
In a standalone build, Clang binaries should end up in Clang's build folder,
not LLVM's.
Xcode still has a few issues finding auxiliary tools and libraries in the
build folders. I'll fix those next.

We have been seeing nasty directory layout with CMake multiconfig, such as,
bin/Release/clang.exe
lib/clang/3.x/...
lib/Release/clang/3.x/.. (duplicated)
Move the layout similar to autoconf's;
Release/bin/clang.exe
Release/lib/clang/3.x/...
Checked on Visual Studio 10. Could you guys please confirm my change on XCode(and other multiconfig builders)?
Note: Don't set variables CMAKE_*_OUTPUT_DIRECTORY any more, or a certain builder, for eaxample, msbuild.exe, would be confused.
llvm-svn: 198205
Also stop setting passing -dead_strip explicitly for libclang and instead
rely on this now happening by default. (And make it happen by default for
add_clang_library, which doesn't use the library cmake functions from llvm.)
llvm-svn: 198200
- If llvm-config fails, output an error to the user rather than allowing
errors to cascade.
- Always get llvm-tblgen from llvm-config's bindir.
Turns out my PATH points to a really old version of LLVM; both of these
fell out of trying to make this experience nicer.
llvm-svn: 197714
Checked on VS10(multiconfig) and some singleconfig builders.
* Assumptions
- You should specify llvm-config as LLVM_CONFIG.
CMake could find one in $PATH by default.
- ENABLE_ASSERTIONS obeys LLVM's.
* Use cases
a) With LLVM build tree
Assume llvm-config is in your build tree.
Everything should work as ever.
b) With *installed* LLVM
Assume distributions. The source tree can be optional.
b1) The source tree is provided on the location `llvm-config --src-root`
- Test utils, FileCheck &c., are imported and built in the new tree.
- Gtest is built in the tree if gtest library is not found.
- Lit is used in $(SRCROOT)/utils/lit/lit.py.
b2) The source tree is not provided
- clang and utilities can be built.
- All tests, unittests and check-clang are invalidated and not built.
llvm-svn: 197697
CMake does not have the ability to perform actions before calculating
dependencies, so it can't know whether it needs to rebuild clangBasic
to update for a new revision number. CLANG_ALWAYS_CHECK_VC_REV (off by
default) will cause clangBasic to always be dirty by deleting the
generated SVNVersion.inc after use; otherwise, SVNVersion.inc will
always be updated, but only included in the final binary when clangBasic
is rebuilt.
It'd be great to find a better way to do this, but hopefully this is
still an improvement over the complete lack of version information before.
