2016-11-01Fix llvm-shlib cmake buildChris Bieneman1-22/+20
Summary: This fixes a few things that used to work with a Makefile build, but were broken in cmake. 1. Treat MINGW like a Linux system. 2. The shlib should never contain other shared libraries.

2016-05-25[CMake] LINK_LIBS need to be public for Darwin dylib targetsChris Bieneman1-0/+11
This should actually address PR27855. This results in adding references to the system libs inside generated dylibs so that they get correctly pulled in when linking against the dylib. llvm-svn: 270723
2016-04-25[CMake] If set we should pass LLVM_VERSION_INFO into config.hChris Bieneman1-2/+0
Autoconf used to support setting LLVM_VERSION_INFO and there is some code filtered around llvm in Support/CommandLine.cpp and LTO/LTOCodeGenerator.cpp that uses it if it is set. We also shouldn't be explicitly setting it as a define on llvm-shlib. It is pointless there because there is no code using it in llvm-shlib, and it is better to have it as part of the generated config.h so that it is available everywhere. llvm-svn: 267490
2016-03-14llvm-shlib: Remove the option to override __cxa_atexitJustin Bogner1-7/+0
If anybody is actually using this, it probably doesn't do what they think it does. This actually causes the dylib to *export* a __cxa_atexit symbol, so anything that links it probably loses their exit time destructors as well as disabling LLVM's. This just removes the option entirely. If somebody does need this behaviour we should figure out a more principled way to do it. This is effectively a revert of r223805. llvm-svn: 263498

compatible with ldconfig Summary: This change makes the CMake build system generate libraries for Linux and Darwin matching the makefile build system. Linux libraries follow the pattern lib${name}.${MAJOR}.${MINOR}.so so that ldconfig won't pick it up incorrectly. Darwin libraries are not versioned. Note: On linux the non-versioned symlink is generated at install-time not build time. I plan to fix that eventually, but I expect that is good enough for the purposes of fixing this bug.

2015-10-27[CMake] Get rid of LLVM_DYLIB_EXPORT_ALL, and make it the default, add ↵Chris Bieneman1-40/+41
libLLVM-C on darwin to cover the C API needs. Summary: We've had a lot of discussion in the past about the meaningful and useful default behaviors for the llvm-shlib tool. The original implementation was heavily geared toward Apple's use, and I think that was wrong. This patch seeks to correct that. I've removed the LLVM_DYLIB_EXPORT_ALL variable and made libLLVM export everything by default. I've also added a new target that is only built on Darwin for libLLVM-C as a library that re-exports the LLVM-C API. This library is not built on Linux because ELF doesn't support re-export libraries in the same way MachO does.

2015-09-05[cmake] rework LLVM_LINK_LLVM_DYLIB option handlingAndrew Wilkins1-47/+4
Summary: This diff attempts to address the concerns raised in http://reviews.llvm.org/D12488. We introduce a new USE_SHARED option to llvm_config, which, if set, causes the target to be linked against libLLVM. add_llvm_utility now uniformly disables linking against libLLVM. These utilities are not intended for distribution, and this keeps the option handling more centralised. llvm-shlib is now processes before any other "tools" subdirectories, ensuring the libLLVM target is defined before its dependents. One main difference from what was requested: llvm_config does not prune LLVM_DYLIB_COMPONENTS from the components passed into explicit_llvm_config. This is because the "all" component does something special, adding additional libraries (namely libLTO). Adding the component libraries after libLLVM should not be a problem, as symbols will be resolved in libLLVM first. Finally, I'm not really happy with the DISABLE_LLVM_LINK_LLVM option, but I'm not sure of a better way to get the following: - link all tools and shared libraries to libLLVM if LLVM_LINK_LLVM_DYLIB is set - some way of explicitly *not* doing so for utilities and libLLVM itself Suggestions for improvement here are particularly welcome.

2015-09-01Enable linking tools, shared libraries against libLLVMAndrew Wilkins1-5/+36
Summary: Three closely related changes, to have a mode in which we link all executables and shared libraries against libLLVM. 1. Add a new LLVM_LINK_LLVM_DYLIB cmake option, which, when ON, will link executables and shared libraries against libLLVM. For this to work, it is necessary to also set LLVM_BUILD_LLVM_DYLIB and LLVM_DYLIB_EXPORT_ALL. It is not strictly necessary to set LLVM_DISABLE_LLVM_DYLIB_ATEXIT, but we also default to OFF in this mode, or tools tend to misbehave (e.g. stdout may not flush on exit when output is buffered.) llvm-config and Tablegen do not use libLLVM, as they are dependencies of libLLVM. 2. Modify llvm-go to take a new flag, "linkmode=component-libs|dylib". Depending on which one is passed (default is component-libs), we link with the individual libraries or libLLVM respectively. We pass in dylib when LLVM_LINK_LLVM_DYLIB is ON. 3. Fix LLVM_DYLIB_EXPORT_ALL on Linux, and expand the symbols exported to actually export all. Don't strip leading underscore from symbols on Linux, and make sure we get all exported symbols and weak-with-default symbols ("W" in nm output). Without these changes, passes won't load because the "Annotate..." symbols defined in lib/Support/Valigrind.cpp are not found. Testing: - Ran default build ("ninja") with LLVM, clang, compiler-rt, llgo, lldb. - Ran "check", "check-clang", "check-tsan", "check-libgo" targets. I've never had much success with LLDB tests, and llgoi is currently broken so check-llgo fails for an unrelated reason. - Ran "lldb" to ensure it loads.

2015-08-18[PM/AA] Remove the last relics of the separate IPA library from LLVM,Chandler Carruth1-1/+0
folding the code into the main Analysis library. There already wasn't much of a distinction between Analysis and IPA. A number of the passes in Analysis are actually IPA passes, and there doesn't seem to be any advantage to separating them. Moreover, it makes it hard to have interactions between analyses that are both local and interprocedural. In trying to make the Alias Analysis infrastructure work with the new pass manager, it becomes particularly awkward to navigate this split. I've tried to find all the places where we referenced this, but I may have missed some. I have also adjusted the C API to continue to be equivalently functional after this change.

2014-12-29[cmake] Start making LLVM_LIBDIR_SUFFIX effective by adding it toChandler Carruth1-1/+1
*numerous* places where it was missing in the CMake build. The primary change here is that the suffix is now actually used for all of the lib directories in the LLVM project's CMake. The various subprojects still need similar treatment. This is the first of a series of commits to try to make LLVM's cmake effective in a multilib Linux installation. I don't think many people are seriously using this variable so I'm hoping the fallout will be minimal. A somewhat unfortunate consequence of the nature of these commits is that until I land all of them, they will in part make the brokenness of our multilib support more apparant. At the end, things should actually work. llvm-svn: 224919
2014-12-09Adding a new option to CMake to disable C++ atexit on llvm-shlib.Chris Bieneman1-0/+7
Summary: This is desirable for WebKit and other clients of the llvm-shlib because C++ exit time destructors have a tendency to crash when invoked from multi-threaded applications. Ideally this option will be temporary, because the ideal fix is to just not have exit time destructors.

2014-11-10[CMake] Let llvm-shlib work on Linux with --whole-archive.NAKAMURA Takumi1-4/+10
FIXME: It should work on not only Linux but elf-targeting gnu ld. For example if LLVM_DYLIB_COMPONENTS is "BitWriter Support", CMake emits the command line like; -Wl,--whole-archive lib/libLLVMBitWriter.a lib/libLLVMSupport.a *1 -Wl,--no-whole-archive lib/libLLVMCore.a lib/libLLVMSupport.a *2 -lrt -ldl -ltinfo -lpthread -lm It works since symbols in LLVMCore is resolved with not *2 but *1. Unfortunately, --gc-sections is not powerful in this case to prune unused "visibility(default)" entries. I am still experimenting other way not to rely on --whole-archive. llvm-svn: 221591

2014-10-23Adding llvm-shlib to CMake build system with a few new bells and whistlesChris Bieneman2-0/+108
Summary: This patch adds a new CMake build setting LLVM_BUILD_LLVM_DYLIB, which defaults to OFF. When set to ON, this will generate a shared library containing most of LLVM. The contents of the shared library can be overriden by specifying LLVM_DYLIB_COMPONENTS. LLVM_DYLIB_COMPONENTS can be set to a semi-colon delimited list of any LLVM components that you llvm-config can resolve. On Windows, unless you are using Cygwin, you must specify an explicit symbol export file using LLVM_EXPORTED_SYMBOL_FILE. On Cygwin and all unix-like platforms if you do not specify LLVM_EXPORTED_SYMBOL_FILE, an export file containing only the LLVM C API will be auto-generated from the list of LLVM components specified in LLVM_DYLIB_COMPONENTS.

This kind of simplification is sometimes useful, but in general it's not correct. As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the build definitions used for FreeBSD, whereas for userland-related issues we want to match the definitions used for other systems with Glibc.
