2012-02-28Temporarily revert r151609, which enabled a new warning for LLVM andChandler Carruth
Clang builds. The detection logic for compilers that support the warning isn't working. Rafael is going to investigate it, but didn't want people to have to wade through build spam until then. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151649 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-13add LLVM_VERSION_MAJOR and _MINOR definesDylan Noblesmith
This is useful for clients that want to maintain compatibility across multiple releases of LLVM. Currently users like Klee and Mesa all have to roll their own 'parse llvm-config --version output and generate defines' solution. Also reuse the new macros so that version information is less redundant/likely to fall out of sync again in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150405 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-04use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJITSebastian Pop
Get back getHostTriple. For JIT compilation, use the host triple instead of the default target: this fixes some JIT testcases that used to fail when the compiler has been configured as a cross compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147542 91177308-0d34-0410-b5e6-96231b3b80d8

CMake versions 2.8.4 and earlier were giving this error since r146323: "string end index: -1 is out of range 0 - 6" Passing -1 as the length of the desired substring was a new feature added in CMake 2.8.5: http://www.cmake.org/Bug/view.php?id=10740 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146372 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-10Use a simpler and more reliable command for converting from HEAD toChandler Carruth

2011-12-10Teach the VCS detection to set some root-level variables with the rawChandler Carruth
revision and git commit data extracted. This will be used in the Clang CMake build to avoid trying to re-detect the information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146324 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-10At the request of Michael Spencer, make the VCS version detection logicChandler Carruth
in CMake a bit more handy. Previously we would get such charming versions as the following for revision NNNN and commit-ish XXXXX: 3.1svnsvn-rNNNN 3.1svngit-svn-rNNNN 3.1svngit-svn-XXXXX The mechanism selecting betwene the latter two was particularly odd, and didn't work with all of the ways git-svn repos are set up apparently. It also misses an important point -- both the revision *and* the git commit might be relevant when working on a local branch some distance from mainline. The new logic does several things: 1) It strips the redundant initial 'svn'. 2) It always looks for a git-svn revision number base, and when found includes it in the version. 3) If the git commit-ish for the current HEAD is not exactly that revision number, it is also included. The resulting strings should roughly be: 3.1svn-rNNNN 3.1git-svn-rNNNN 3.1git-svn-rNNNN-XXXXX Suggestions on formatting etc always welcome. =] I've only looked at the LLVM version string here, not Clang's (yet). Note that the commit-ish reported is *not* terribly accurate. It updates when 'cmake' is run, not when the binary is built. Still, it may be better than nothing, especially if people have fairly long-lived git repos and branches. This is not a new limitation, just didn't want anyone to be surprised. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146323 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-29build/cmake: Switch to using llvm-build computed dependencies.Daniel Dunbar
- I verified locally that the current dependency lists are identical. - This makes add_llvm_library_dependencies() a no-op. I'll remove it once this change passes the bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145355 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-28rename ENABLE_THREADS to LLVM_ENABLE_THREADSDylan Noblesmith
Now that it needs to be exported in a public header (Valgrind.h) it should be prefixed to avoid collision with other projects. Add it to llvm-config.h as well. This'll require regenerating the configure script after this commit, but I don't have the required autoconf version. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145214 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-02The TableGen parts of the CMake build are seriously broken. This fixesChandler Carruth
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

2011-07-30Remove yet another buried and hidden implicit dependency: every singleChandler Carruth
sub-library for the targets depended on the core target CodeGen library. This completely undermined the careful work to separate the those libraries, especially the MC-layer ones. This surfaced as circular dependencies when the libraries were built as shared libraries where CMake doesn't allow cycles. This should fix PR10537. I'll watch the bots to see if there is fallout on other platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136565 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Make my attempt to build up global deps variables actually utilizeChandler Carruth
globally scoped constructs. Also, round-trip these dependencies through the LLVMConfig.cmake.in file thata is used by CMake-based clients of "installed" (or built) LLVM trees. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136543 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Rewrite the CMake build to use explicit dependencies between libraries,Chandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136433 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-26Still more library dependency updates. This reflects the ever decreasingChandler Carruth
dependence on CodeGen layers and backends from the MC layers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136024 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Clean up a pile of hacks in our CMake build relating to TableGen.Chandler Carruth
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
2011-07-25Check in updated CMake dependencies after Evan's latest round ofChandler Carruth
refactorings. Several places that shouldn't have dependend on Target no longer do. Also almost all of the CodeGen dependencies have gone away for the MCDisassembler. Others add reasonable dependencies within the target-specific layers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135977 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-22Move TargetRegistry.cpp from lib/Support to lib/Target where it belongs.Chandler Carruth
The header file was already properly located. The previous need for it in Support had to do with the version string printing which was fixed in r135757. Also update build dependencies where libraries that needed the functionality of the Target library (in the form of the TargetRegistry) were picking it up via Support. This is pretty pervasive, essentially every TargetInfo library (ARMInfo, etc) uses TargetRegistry, making it depend on Target. All of these were previously just sneaking by. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135760 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-22Update the CMake library dependencies. These shifts are the result ofChandler Carruth
Evan's recent refactorings (I believe). Specifically, MCDisassembler no longer depends on Target, and ARMDisassembler no longer depends on CodeGen. The added dependencies from ARMAsmParser to ARMDesc looks correct based on header file inclusion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135759 91177308-0d34-0410-b5e6-96231b3b80d8
