* Enabling LLVM & Clang to be cross-compiled using CMake from a single ↵Chris Bieneman2014-09-031-34/+5
| | | | | | | | 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. llvm-svn: 217105
* CMake: avoid a reconfigure loop from r213091Alp Toker2014-07-151-2/+1
| | | | | | | Removing the native CMakeCache.txt causes the target to get re-run needlessly on some systems. We'll want another solution for that part of the fix. llvm-svn: 213099
* CMake: fix cross-compilation with external source directoriesAlp Toker2014-07-151-1/+11
| | | | | | | | This adds support for building native artifacts when cross-compiling using the popular side-by-side source directory layout (no symlinks, no nested repositories). llvm-svn: 213091

| | | | | | | | | | | This macro depends on several variables to be set in the calling context. Check them and report an error if they are not set. Without this, custom commands may be silently specified that will fail at build time. Patch by Brad King. llvm-svn: 201229

| | | | | | | | | | | | | | | Record every logical target that we install with install(TARGETS) in a global LLVM_EXPORTS property. Then use the export(TARGETS) command to provide a "LLVMExports.cmake" file that exports logical targets for import into applications directly from our build tree. The "LLVMExports.cmake" file is not meant for direct inclusion by application code but should be included by "LLVMConfig.cmake" in a future change. Contributed by Brad King. llvm-svn: 201050

| | | | | | | | | This changes Clang standalone builds so that clang-tblgen lives in clang/build/bin instead of llvm/build/bin, and so that with the Xcode generator it's in clang/build/bin/Debug instead of llvm/build/bin/Debug/Debug/. Yes, really. llvm-svn: 197590

* [CMake] Let add_public_tablegen_target() provide intrinsics_gen, too.NAKAMURA Takumi2013-11-281-1/+1
| | | | | | | | | | I think, in principle, intrinsics_gen may be added explicitly. That said, it can be added incidentally, since each target already has dependencies to llvm-tblgen. Almost all source files depend on both CommonTaleGen and intrinsics_gen. Explicit add_dependencies() have been pruned under lib/Target. llvm-svn: 195929

* Windows: Add support for unicode command linesDavid Majnemer2013-10-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The MSVCRT deliberately sends main() code-page specific characters. This isn't too useful to LLVM as we end up converting the arguments to UTF-16 and subsequently attempt to use the result as, for example, a file name. Instead, we need to have the ability to access the Unicode command line and transform it to UTF-8. This has the distinct advantage over using the MSVC-specific wmain() function as our entry point because: - It doesn't work on cygwin. - It only work on MinGW with caveats and only then on certain versions. - We get to keep our entry point as main(). :) N.B. This patch includes fixes to other parts of lib/Support/Windows s.t. we would be able to take advantage of getting the Unicode paths. E.G. clang spawning clang -cc1 would want to give it Unicode arguments.

* cmake: Install llvm-tblgen againHans Wennborg2013-09-101-0/+4
| | | | | | | | | | | It was removed in r189130, but it turns out this makes life hard for folks packaging LLVM and Clang and building the latter based on the LLVM package. Note that this only adds back the LLVM tblgen, and it's obviously not included when LLVM_INSTALL_TOOLCHAIN_ONLY is set. llvm-svn: 190419
* CMake Xcode builds: symlink tblgen targets out to bin/.Douglas Gregor2013-08-261-0/+10
| | | | | | | | | | | Xcode always puts executable targets in the directory bin/<Config>. When building separate LLVM and Clang projects for Xcode, this prevents the CMake-configured project for Clang from finding llvm-tblgen. Add a symlink so that tblgen executables are always available in bin/ (regardless of the configuration LLVM is built with). llvm-svn: 189220
* CMake: don't install tablegenHans Wennborg2013-08-231-2/+0
| | | | | | | | Since it's an llvm-internal tool, we shouldn't install it. (This depends on Clang r189127 and lld r189128.) llvm-svn: 189130

* The TableGen parts of the CMake build are seriously broken. This fixesChandler Carruth2011-11-021-1/+3
| | | | | | | | | | | | | | one aspect of them by having them use the (annoying, if not broken) proper library dependency model for adding the LLVMTableGen library as a dependency. This could manifest as a link order issue in the presence of separate LLVM / Clang source builds with CMake and a linker that really cares about such things. Also, add the Support dependency to llvm-tblgen itself so that it doesn't rely on TableGen's transitive Support dependency. A parallel change for clang-tblgen will be forthcoming. llvm-svn: 143531

* Clean up a pile of hacks in our CMake build relating to TableGen.Chandler Carruth2011-07-261-16/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first problem to fix is to stop creating synthetic *Table_gen targets next to all of the LLVM libraries. These had no real effect as CMake specifies that add_custom_command(OUTPUT ...) directives (what the 'tablegen(...)' stuff expands to) are implicitly added as dependencies to all the rules in that CMakeLists.txt. These synthetic rules started to cause problems as we started more and more heavily using tablegen files from *subdirectories* of the one where they were generated. Within those directories, the set of tablegen outputs was still available and so these synthetic rules added them as dependencies of those subdirectories. However, they were no longer properly associated with the custom command to generate them. Most of the time this "just worked" because something would get to the parent directory first, and run tablegen there. Once run, the files existed and the build proceeded happily. However, as more and more subdirectories have started using this, the probability of this failing to happen has increased. Recently with the MC refactorings, it became quite common for me when touching a large enough number of targets. To add insult to injury, several of the backends *tried* to fix this by adding explicit dependencies back to the parent directory's tablegen rules, but those dependencies didn't work as expected -- they weren't forming a linear chain, they were adding another thread in the race. This patch removes these synthetic rules completely, and adds a much simpler function to declare explicitly that a collection of tablegen'ed files are referenced by other libraries. From that, we can add explicit dependencies from the smaller libraries (such as every architectures Desc library) on this and correctly form a linear sequence. All of the backends are updated to use it, sometimes replacing the existing attempt at adding a dependency, sometimes adding a previously missing dependency edge. Please let me know if this causes any problems, but it fixes a rather persistent and problematic source of build flakiness on our end. llvm-svn: 136023

| | | | | | | | | | | (clang/include/clang/Basic/StmtNodes.td, for instance, is tablegenned from clang/include/clang/AST/CMakeLists.txt) so it is not contained on the list of all .td files on the current source directory which is used as the DEPENDS of the custom command. We must add the .td file to the DEPENDS list of the custom command. Otherwise some .inc files are not regenerated when the corresponding .td file changes. llvm-svn: 122768
