2024-07-06cmake/findllvm: fix incorrect lib dir setup for zig2Erik Arvstedt
Line `link_directories("${CMAKE_PREFIX_PATH}/lib")` was evaluated as `link_directories("/lib")` in the default case of `CMAKE_PREFIX_PATH` being empty. This caused cmake to add `-L/lib -Wl,-rpath,/lib` to the zig2 build flags. This could result in errors on systems where libraries set via `CMAKE_LIBRARY_PATH` had conflicting versions in `/lib`: - `-L/lib` could cause linking zig2 to fail - `-Wl,-rpath,/lib` adds `/lib` as the first entry of the zig2 `RPATH`. This could cause running zig2 (to build zig3) to fail. In case of conflicting lib dirs, cmake emitted this warning, which is now fixed: ``` Cannot generate a safe runtime search path for target zig2 because files in some directories may conflict with libraries in implicit directories: runtime library [libclang-cpp.so.18.1] in /nix/store/...-clang-18.1.5-lib/lib may be hidden by files in: /lib ```

This reverts commit 28476a5ee94d311319941b54e9da66210690ce70. It also adds a comment to explain the purpose of this line, to prevent this mistake from being repeated.

This reverts commit 55c3efcb58cc153fc3109a61c6949e470b57b81e. This caused a regression when building Zig with Homebrew. Also I don't like that it prints a message on success. Only when there is a problem should an error message be printed. closes #14093

2022-07-31cmake: Print all LLVM config errors instead of just the last onesin-ack
If you have multiple llvm-config executables in your path, and all of them cause failures, then only the last failure will be printed. This can cause confusion when the multiple llvm-config executables are from different major LLVM versions, i.e. LLVM 13 and 14, which might mask an error that happened on the LLVM 14 llvm-config with an unrelated error. This commit makes it so that all errors are collected into a list and printed all at once; this way, you can see how each llvm-config executable failed to configure properly. Note that the failures still won't be printed if a successful configuration is found.

2022-07-23CMake: Search more permissively for LLDCody Tapscott
This change relaxes the restriction added in the prior commit that LLD should be alongside LLVM. This also leaves unresolved the issue of making sure the link mode (static or shared) of LLD matches that of LLVM/Clang. That would be an unfortunate restriction, since LLD seems to be provided only as a static lib on some distros.
2022-07-23CMake: Improve usage of `llvm-config`, esp. for consistent linkingCody Tapscott
This commit reworks the LLVM/Clang/LLD discovery process for CMake. The biggest changes are that: 1. We search for LLVM from most preferred directory to least, skipping any `llvm-config` that is the wrong version, or that doesn't support the requested link mode ("static" or "shared"). 2. `ZIG_PREFER_CLANG_CPP_DYLIB` has been renamed to `ZIG_SHARED_LLVM`, to better align with `ZIG_STATIC_LLVM`. 3. We only search for LLVM in the same directory alongside LLVM. 4. LLVM's link mode is forwarded to Clang, so that we can look for the appropriate shared/static libraries. 5. We use `--link-static` when querying `--system-libs` from llvm-config, so that this will include libz and other dependencies for statically linking LLD
2022-07-14CMake: Use NAMES_PER_DIR in all lookupsCody Tapscott
CMake has a surprising default behavior where looking up a library by multiple names gives the name order higher priority than the directory search order. For example, if your system provides "llvm-config-14" and CMAKE_PREFIX_PATH includes "llvm-config", CMake will always end up choosing the system-provided llvm-config-14. This change add NAMES_PER_DIR to request the more sensible behavior: directory search order has higher priority than name order, so CMAKE_PREFIX_PATH always wins over system-provided tools/libraries.

2021-09-15Merge remote-tracking branch 'origin/master' into llvm13Andrew Kelley
Conflicts: * cmake/Findclang.cmake * cmake/Findlld.cmake * cmake/Findllvm.cmake In master branch, more search paths were added to these files with "12" in the path. In this commit I updated them to "13". * src/stage1/codegen.cpp * src/zig_llvm.cpp * src/zig_llvm.h In master branch, ZigLLVMBuildCmpXchg is improved to add `is_single_threaded`. However, the LLVM 13 C API has this already, and in the llvm13 branch, ZigLLVMBuildCmpXchg is deleted in favor of the C API. In this commit I updated stage2 to use the LLVM 13 C API rather than depending on an improved ZigLLVMBuildCmpXchg. Additionally, src/target.zig largestAtomicBits needed to be updated to include the new m68k ISA.
2021-09-08cmake: also check Homebrew install paths when looking for LLVMFnControlOption
- On Intel Macs, the path is /usr/local/opt/llvm@12 - On Silicon Macs, the path is /opt/homebrew/opt/llvm@12 This makes specifying CMAKE_PREFIX_PATH optional for Homebrew LLVM.

2021-03-13cmake build: allow overriding whether to use llvm-configAndrew Kelley
Previously, there was an option ZIG_PREFER_LLVM_CONFIG which would override the default of not using llvm-config when cross compiling. That option is now removed in favor of the more powerful ZIG_USE_LLVM_CONFIG which defaults to OFF for cross compiling and ON for native compilation. The option overrides the default. This will be used in zig-bootstrap to improve support for native builds.

Conflicts: cmake/Findllvm.cmake The llvm11 branch changed 10's to 11's and master branch added the "using LLVM_CONFIG_EXE" help message, so the resolution was to merge these changes together. I also added a check to make sure LLVM is built with AVR enabled, which is no longer an experimental target.

2020-09-26Print the llvm-config path on configuration errorFrank Denis
This is helpful on systems with multiple LLVM installations. For example, OpenBSD ships with LLVM in the base system, but without support for extra targets. A full LLVM version can be installed using the ports system, but even when it is, `cmake` is not going to pick it up unless `/usr/local` is explicitly added to the `cmake` search paths. Having the full `llvm-config` path printed on error is helpful to understand that the detected LLVM version was not the expected one.

2020-04-06cmake: improvements to cross-compiling for WindowsAndrew Kelley
* don't unconditionally pass -lz3 for mingw builds. If mingw builds require this then the llvm-config executable should put it as part of --system-libs. If there is a bug and it does not do that, and we need a workaround, then the workaround should be an explicit cmake option. * don't link libstage2.a against -lntdll. This causes zig to set `builtin.link_mode == .Dynamic` and include the TLS definitions, which then collide with the mingw-w64 symbols. This should probably be addressed separately, but for now this solves the problem and there is no reason to link a static library against a DLL. * Findllvm.cmake no longer treats the libraries as "optional" and will emit a cmake error if one is not found. Additionally, the not-required LLVM library LLVMTableGen is omitted.
