2018-11-16[CMake] Support cross-compiling with multi-stage buildsPetr Hosek
When using multi-stage builds, we would like support cross-compilation. Example is 2-stage build when the first stage is compiled for host while the second stage is compiled for the target. Normally, the second stage would be also used for compiling runtimes, but that's not possible when cross-compiling, so we use the first stage compiler instead. However, we still want to use the second stage paths. To do so, we set the -resource-dir of the first stage compiler to point to the resource directory of the second stage. We also need compiler tools that support the target architecture. These tools are not guaranteed to be present on the host, but in case of multi-stage build, we can build these tools in the first stage.

2018-11-13CMake: Deprecate using llvm-config to detect llvm installationTom Stellard
Summary: clang currently uses llvm-config to determine the installation paths for llvm's headers and binaries. clang is also using LLVM's cmake files to determine other information about the LLVM build, like LLVM_LIBDIR_SUFFIX, LLVM_VERSION_*, etc. Since the installation paths are also available via the cmake files, we can simplify the code by only relying on information from cmake about the LLVM install and dropping the use of llvm-config altogether. In addition to simplifying the code, the cmake files have more accurate information about the llvm installation paths. llvm-config assumes that the lib, bin, and cmake directories are always located in the same place relative to the path of the llvm-config executable. This can be wrong if a user decides to install headers, binaries or libraries to a non-standard location: e.g. static libraries installed to /usr/lib/llvm6.0/ This patch takes the first step towards dropping llvm-config by removing the automatic detection of llvm-config (users can still manually supply a path to llvm-config by passing -DLLVM_CONFIG=/usr/bin/llvm-config to cmake) and adding a deprecation warning when users try to use this option.

Make the check_include_file* macros honor CMAKE_REQUIRED_LIBRARIES. This shouldn't cause any of the configuration checks to give different results, and I verified that a clean configure before and after this change resulted in identical CMake caches on my machine.

2018-10-13[analyzer] Improved cmake configuration for Z3Enrico Steffinlongo
Summary: Enhanced support for Z3 in the cmake configuration of clang; now it is possible to specify any arbitrary Z3 install prefix (CLANG_ANALYZER_Z3_PREFIX) to cmake with lib (or bin) and include folders. Before the patch only in cmake default locations were searched (https://cmake.org/cmake/help/v3.4/command/find_path.html). Specifying any CLANG_ANALYZER_Z3_PREFIX will force also CLANG_ANALYZER_BUILD_Z3 to ON. Removed also Z3 4.5 version requirement since it was not checked, and now Clang works with Z3 4.7 Reviewers: NoQ, george.karpenkov, mikhail.ramalho Reviewed By: george.karpenkov Subscribers: rnkovacs, NoQ, esteffin, george.karpenkov, delcypher, ddcc, mgorny, xazax.hun, szepet, a.sidorin, Szelethus Tags: #clang Differential Revision: https://reviews.llvm.org/D50818 llvm-svn: 344464

Add installation support for the python bindings for libclang. Add an additional CMake configuration variable to enumerate the python versions for which the bindings should be installed.

2018-06-21Re-apply: Add python tool to dump and construct header mapsBruno Cardoso Lopes
Header maps are binary files used by Xcode, which are used to map header names or paths to other locations. Clang has support for those since its inception, but there's not a lot of header map testing around. Since it's a binary format, testing becomes pretty much brittle and its hard to even know what's inside if you don't have the appropriate tools. Add a python based tool that allows creating and dumping header maps based on a json description of those. While here, rewrite tests to use the tool and remove the binary files from the tree. This tool was initially written by Daniel Dunbar. Thanks to Stella Stamenova for helping make this work on Windows.

2018-03-06[FrontEnd] Allow overriding the default C/C++ -std via CMake varsMichal Gorny
Provide two new CMake cache variables -- CLANG_DEFAULT_STD_C and CLANG_DEFAULT_STD_CXX -- that can be used to override the default C/ObjC and C++/ObjC++ standards appropriately. They can be set to one of the identifiers from LangStandards.def, or left unset (the default) to respect the current platform default. This option is mostly intended for compiler vendors that may wish to adjust the defaults their compilers are using. For example, Gentoo planned to use it to set clang and gcc to matching standards, so that we could maintain as much compatibility between different compilers as possible. The code relies on explicit identifiers rather than the string aliases for simplicity. This saves us from the necessity of parsing aliases at build-time or adding additional processing at runtime. For the latter case, it also adds trivial value check -- if incorrect value is passed, the code simply fails to compile through referencing an undefined constant. If the variable is used to redefine the default standard, the explicit value overrides the special case for PS4. It is done this way mostly following other kinds of variables where 'platform defaults' are redefined. Differential Revision: https://reviews.llvm.org/D34365 llvm-svn: 326836
2018-01-19[cmake] Also pass CMAKE_ASM_COMPILER_ID to next stage when bootstrappingDon Hinton
Summary: When setting CMAKE_ASM_COMPILER=clang, we also need to set CMAKE_ASM_COMPILER_ID=Clang. This is needed because cmake won't set CMAKE_ASM_COMPILER_ID if CMAKE_ASM_COMPILER is already set. Without CMAKE_ASM_COMPILER_ID, cmake can't set CMAKE_ASM_COMPILER_OPTIONS_TARGET either, which means CMAKE_ASM_COMPILER_TARGET is ignored, causing cross compiling to fail, i.e., `--target=${CMAKE_ASM_COMPILER_TARGET}` isn't passed.

2017-11-17[cmake] Use llvm-lit directory when provided for stand-alone buildMichal Gorny
After the recent lit test changes, clang attempts to run its tests via llvm-lit by default. However, the llvm-lit binary is not present when performing stand-alone build resulting in a failure out of the box. To solve that, add the llvm-lit directory to CMake when performing a stand-alone build and LLVM sources are provided. This includes the CMake rules generating the llvm-lit binary and effectively makes it possible for clang to use it. Differential Revision: https://reviews.llvm.org/D40142 llvm-svn: 318562

llvm-objcopy is getting to where it can be used in non-trivial ways (such as for dwarf fission in clang). It now supports dwarf fission but this feature hasn't been thoroughly tested yet. This change allows people to optionally build clang to use llvm-objcopy rather than GNU objcopy. By default GNU objcopy is still used so nothing should change.

Clang-proto-fuzzer has already found several bugs in Clang (e.g., https://bugs.llvm.org/show_bug.cgi?id=33747, https://bugs.llvm.org/show_bug.cgi?id=33749). As with clang-fuzzer, clang-proto-fuzzer requires the following cmake flags: - CMAKE_C_COMPILER=clang - CMAKE_CXX_COMPILER=clang++ - LLVM_USE_SANITIZE_COVERAGE=YES // needed for libFuzzer - LLVM_USE_SANITIZER=Address // needed for libFuzzer In addition, clang-proto-fuzzer requires: - CLANG_ENABLE_PROTO_FUZZER=ON clang-proto-fuzzer also requires the following dependencies: - binutils // needed for libprotobuf-mutator - liblzma-dev // needed for libprotobuf-mutator - libz-dev // needed for libprotobuf-mutator - docbook2x // needed for libprotobuf-mutator - Recent version of protobuf [3.3.0 is known to work] A working version of libprotobuf-mutator will automatically be downloaded and built as an external project.
