package/llvm-project: bump to version 20.1.5

Release:
https://github.com/llvm/llvm-project/releases/tag/llvmorg-20.1.5

Major Changes and Fixes:

-- CMake 3.20 minimum required

-- Issue encountered during standalone LLVM build:
    CMake Error at CMakeLists.txt:8 (include):
      include could not find requested file:

  This error is due to the line:
    include(${LLVM_COMMON_CMAKE_UTILS}/Modules/CMakePolicy.cmake)

  Upstream commit [1] harmonized policy handling by introducing this shared include
  for all LLVM sub-projects. However, in the LLVM CMakeLists, LLVM_COMMON_CMAKE_UTILS
  is set unconditionally, preventing external override — which is required in
  Buildroot when building from separated archives.

  To solve this:
    We apply a patch to wrap the assignment of LLVM_COMMON_CMAKE_UTILS in an
    `if(NOT DEFINED ...)` block, allowing Buildroot to set the path externally.
    In the `llvm-cmake` package, we also **adjust the installation path** of the
    CMake modules: instead of installing directly into `lib/cmake/llvm`, we now
    install them under `lib/cmake/llvm/Modules` to match the expected layout.

  This ensures that:
    LLVM can include `${LLVM_COMMON_CMAKE_UTILS}/Modules/CMakePolicy.cmake`
    without errors.

-- Also the Clang build system has removed support for
   the GCC_INSTALL_PREFIX option, raising a fatal error when attempting to use it:

   CMake Error at CMakeLists.txt:211 (message):
      GCC_INSTALL_PREFIX is deprecated and will be removed.
      Use configuration files (https://clang.llvm.org/docs/UsersManual.html#configuration-files)
      to specify the default --gcc-install-dir= or --gcc-triple=.
      --gcc-toolchain= is discouraged.
      See https://github.com/llvm/llvm-project/pull/77537
      for details.

   Remove the use of GCC_INSTALL_PREFIX and replace it with a
   Clang configuration file as recommended by upstream.

   A configuration file is now automatically generated at:
   $(HOST_DIR)/lib/clang/$(CLANG_VERSION_MAJOR)/$(GNU_TARGET_NAME).cfg

   It contains:
   --gcc-install-dir=<path to external toolchain's lib/gcc/...>
   --target=<GNU target triplet>

   We dynamically detect the GCC install path by scanning
   $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/lib/gcc/<target>/<version>/

   The Clang toolchain wrapper was also updated to add --config=<file> when
   BR_CLANG_CONFIG_FILE is defined.

-- Fix LLVM_MAIN_SRC_DIR path:
   set(LLVM_MAIN_SRC_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../llvm" CACHE PATH ...)
   This path isn't correct when using standalone archive builds. We explicitly pass
   LLVM_MAIN_SRC_DIR=$(BUILD_DIR)/llvm-$(LLVM_PROJECT_VERSION) to fix the path. [2]

-- Add LLVM_ENABLE_RUNTIMES:
   Upstream added LLVM_ENABLE_RUNTIMES for runtimes [3]

-- Removed LLVM_INCLUDE_GO_TESTS:
   Upstream dropped this option; we remove it too [4]

-- Disable TensorFlow Lite integration:
   LLVM_HAVE_TFLITE is added to the CMakelist
   We now explicitly disable it to avoid unexpected
   TensorFlow Lite dependency.

-- Clang introduced CLANG_ENABLE_LIBXML2 [5]
   We now explicitly disable it by setting CLANG_ENABLE_LIBXLM2=OFF
   since we set LLVM_ENABLE_LIBXML2 to OFF in LLVM

-- Host-python3, which is now always needed by Clang’s resource bundling
   script. [6]

-- Clang explicitly request to disable llvm tests when llvm_gtest is missing.[7]
   CMake Error at CMakeLists.txt:126 (message):
    llvm-gtest not found. Please install llvm-gtest or disable tests with
    -DLLVM_INCLUDE_TESTS=OFF

-- Also update the installation path in COMPILER_RT_SETUP_RUNTIME_LIBS
   to use CLANG_VERSION_MAJOR instead of HOST_CLANG_VERSION,
   ensuring that the runtime files are placed correctly
   in the /lib/clang/<major>/ folder. [8]

-- Add llvm-runtimes dependency
   libunwind needs runtimes [9]

-- Fix for libclc out of tree patch
   Due to upstream changes in libclc, the old patch no longer
   applies. Only the fix related to invoking './prepare_builtins'
   directly is still relevant and preserved, as it is required to avoid
   a build failure when the binary is not in PATH.

-- Upstream commit [10] removed the use of llvm-config in libclc and
   replaced it with proper use of LLVM_CMAKE_DIR. We now pass
   -DLLVM_CMAKE_DIR instead of DLLVM_CONFIG

-- Libclc expects to invoke some LLVM tools. We explicitly set
   LIBCLC_CUSTOM_LLVM_TOOLS_BINARY_DIR to ensure it finds these tools. [11]

-- Remove LLAsm_COMPILER and CLC_COMPILER [12]

-- LIBUNWIND_INSTALL_HEADERS is On by default [13]

-- Update spirv-llvm-translator to align with LLVM 20.1.5

-Subject: [PATCH] lib/Driver/ToolChains/Gnu: Use GCC_INSTALL_PREFIX in the set
- of prefixes for searching the gcc toolchain
-
-By default, the Gnu Toolchains driver is looking at the parent
-directory while looking for the gcc toolchain when clang is installed
-at "D.InstalledDir"
-
-But this doesn't work with Buildroot since the external
-toolchain is installed in host/opt/ext-toolchain and the sysroot is
-moved to host/<arch>-buildroot-linux-gnu/sysroot/ directory.
-
-We tried by setting GCC_INSTALL_PREFIX in clang.mk for host-clang
-but it doesn't work since we already provide a sysroot [1].
-
-Help the Gnu Toolchains driver by using GCC_INSTALL_PREFIX path.
-
-Since we want to be able to relocate the clang toolchain,
-allow to use a relative path with GCC_INSTALL_PREFIX.
-
-Buildroot will provide such relative path by using:
-HOST_CLANG_CONF_OPTS += -DGCC_INSTALL_PREFIX:PATH=`realpath --relative-to=$(HOST_DIR)/bin/ $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)`
-
-Doing so allow to use clang without providing additional search
-paths with -B option on the clang's command line.

+Date: Sat, 10 May 2025 12:55:07 +0200
+Subject: [PATCH] Fix standalone build for llvm
+
+Upstream commit 9dd01a5241dc ("Harmonize cmake_policy() across standalone builds of all projects")
+moved the `cmake_policy()` settings from `llvm/CMakeLists.txt` into a shared
+`cmake/modules/CMakePolicy.cmake`, and included it from all relevant projects
+(Clang, LLD, LLDB, etc.) to harmonize standalone builds.
+
+However, in `llvm/CMakeLists.txt`, unlike other components, the line:
+    set(LLVM_COMMON_CMAKE_UTILS ...)
+was left **without** the usual:
+    if(NOT DEFINED LLVM_COMMON_CMAKE_UTILS)
+
+This prevents external build systems (e.g., when using separate source archives)
+from overriding the `LLVM_COMMON_CMAKE_UTILS` variable, since the value is
+always reset unconditionally.
+
+This patch adds the missing `if(NOT DEFINED LLVM_COMMON_CMAKE_UTILS)` guard,
+in the same way as it is already done in Clang, LLD, etc., to make
+`LLVM_COMMON_CMAKE_UTILS` properly overridable.
