* Windows: Add support for unicode command linesDavid Majnemer2013-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Wennborg2013-09-10
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190419 91177308-0d34-0410-b5e6-96231b3b80d8
* CMake Xcode builds: symlink tblgen targets out to bin/.Douglas Gregor2013-08-26
| | | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189220 91177308-0d34-0410-b5e6-96231b3b80d8

* The TableGen parts of the CMake build are seriously broken. This fixesChandler Carruth2011-11-02
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143531 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up a pile of hacks in our CMake build relating to TableGen.Chandler Carruth2011-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136023 91177308-0d34-0410-b5e6-96231b3b80d8
