* [CMake] Switch back to -fPIC for Fuchsia ToolchainDaniel Thornburgh2023-04-191-5/+0
| | | | | | | | | | | | This reverts commit 1fab236e6e4575d5af4f4722216df4dd6a872795. Shipping LLDB means distributing libLLDB.so, which will need to be built with PIC. Disabling PIC also removes the libLTO target, which is a hard dependency of the LLDB test suite. Reviewed By: abrachet Differential Revision: https://reviews.llvm.org/D148577

* [Fuchsia] Add FUCHSIA_USE_MULTIPLE_DISTRIBUTIONS.Daniel Thornburgh2023-03-242-11/+52
| | | | | | | | | | | | | | This flag causes the toolchain distribution to be built using LLVM CMake's multiple distribution feature. The distribution* family of CMake targets would be replaced with the toolchain-distribution* family. This shouldn't otherwise affect the semantics of the build, but it sets up the ability to split out the LLDB build from the main distribution used by Fuchsia.

* [Fuchsia] Add LLDB options to stage 1 cmake.Daniel Thornburgh2023-03-072-1/+14
| | | | | | | | | | | | | | | LLVM_ENABLE_PROJECTS is automatically forwarded from stage 1 builds to stage 2 builds, so setting FUCHSIA_ENABLE_LLDB has no effect on two-stage builds. Instead, add FUCHSIA_ENABLE_LLDB to the stage one build as well. This also disables curses and libedit by default for now in both stage1 and stage 2 builds; these should be opt-in.

| | | | | | | | | This reverts commit a6f621b8cacca926d809010c135be038fd05652c. We suspect that this patch might be the culprit that is causing every llvm executable to be sigkill'd immediately on Apple Silicon machines. Notably, the only other cache file with CMAKE_POSITION_INDEPENDENT_CODE is Apple's and they have it off.
* [clang] Replace BACKEND_PACKAGE_STRING with LLVM_VERSION_STRINGFangrui Song2022-10-251-1/+1
| | | | | | | | | | | | | | | | | 420d7ccbac0f499a6ff9595bdbfa99cd3376df22 introduced BACKEND_PACKAGE_STRING to replace `PACKAGE_VERSION` (llvm/Config/config.h) to support standalone builds. This is used in the output of `clang -cc1 -v`. Since llvm-config.h is available for both standalone and non-standalone builds, we can just use `LLVM_VERSION_STRING` from llvm-config.h. clang/cmake/modules/AddClang.cmake uses `VERSION_STRING "${CLANG_VERSION} (${BACKEND_PACKAGE_STRING})"`. Just simplify it to `"${CLANG_VERSION}"` so that we can remove the CMake variable BACKEND_PACKAGE_STRING. Reviewed By: tstellar Differential Revision: https://reviews.llvm.org/D136660

* [CMake] Disable BOLT instrumentation of Clang on instrumented buildAmir Ayupov2022-10-191-0/+11
| | | | | | | | | | | | | | | | | | | | | | This enables multi-stage PGO build optimized by BOLT using BOLT.cmake cache. The issue is that `-DPGO_BUILD_CONFIGURATION` cache file is passed to both stage2-instrumented and stage2-optimized builds (for them to be identical), but in case of BOLT.cmake, it doesn't make sense to BOLT-instrument the instrumented binary (it's not going to be optimized). Hence turn off `CLANG_BOLT_INSTRUMENT` code if `LLVM_BUILD_INSTRUMENTED` is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds `CLANG_BOLT_INSTRUMENT` option that applies BOLT instrumentation to Clang, performs a bootstrap build with the resulting Clang, merges resulting fdata files into a single profile file, and uses it to perform BOLT optimization on the original Clang binary. The projects and targets used for bootstrap/profile collection are configurable via `CLANG_BOLT_INSTRUMENT_PROJECTS` and `CLANG_BOLT_INSTRUMENT_TARGETS`. The defaults are "llvm" and "count" respectively, which results in a profile with ~5.3B dynamically executed instructions. The intended use of the functionality is through BOLT CMake cache file, similar to PGO 2-stage build: ``` cmake <llvm-project>/llvm -C <llvm-project>/clang/cmake/caches/BOLT.cmake ninja clang++-bolt # pulls clang-bolt ``` Stats with a recent checkout (clang-16), pre-built BOLT and Clang, 72vCPU/224G | CMake configure with host Clang + BOLT.cmake | 1m6.592s | Instrumenting Clang with BOLT | 2m50.508s | CMake configure `llvm` with instrumented Clang | 5m46.364s (~5x slowdown) | CMake build `not` with instrumented Clang |0m6.456s | Merging fdata files | 0m9.439s | Optimizing Clang with BOLT | 0m39.201s Building Clang: ```cmake ../llvm-project/llvm -DCMAKE_C_COMPILER=... -DCMAKE_CXX_COMPILER=... -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS=clang -DLLVM_TARGETS_TO_BUILD=Native -GNinja``` | | Release | BOLT-optimized | cmake | 0m24.016s | 0m22.333s | ninja clang | 5m55.692s | 4m35.122s I know it's not rigorous, but shows a ballpark figure.
