本项目为[受支持的工具链](#工具链)提供了xmake支持，下面是一个示例： 147 | 148 | ```lua 149 | -- 导入所有文件 150 | includes("xmake/*.lua") 151 | -- 设置允许的xmake模式 152 | set_allowedmodes(support_rules_table) 153 | -- 根据mode选项添加规则 154 | add_rules(get_config("mode")) 155 | target("test") 156 | add_files("*.cpp") 157 | target_end() 158 | ``` 159 | 160 | 通过`toolchain`选项可以轻松地选取要使用的工具链，并完成`--sysroot`等选项的配置，下面是一个示例： 161 | 162 | ```shell 163 | # 使用clang进行交叉编译 164 | xmake f --toolchain=aarch64-linux-gnu-clang -a arm64-v8a -p linux 165 | # 使用gcc进行交叉编译 166 | xmake f --toolchain=aarch64-linux-gnu-gcc -a arm64-v8a -p linux 167 | ``` 168 | 169 | xmake支持也提供了`target-clang`和`target-gcc`工具链。使用这两个工具链时脚本会尝试根据`plat`和`arch`推导出目标平台，若无法推导则配置失败，此时应该指定一个具体的工具链。 170 | 在常用平台上编译时可以直接使用这两个工具链，而无需在xmake选项和工具链间重复指定目标平台。下面是一个示例： 171 | 172 | ```shell 173 | # 根据arch和plat自动推导工具链，相当于--toolchain=aarch64-linux-gnu-clang 174 | xmake f --toolchain=target-clang -a arm64-v8a -p linux 175 | ``` 176 | 177 | 如果使用`cross`平台，则需要通过`--target_os`选项指定目标平台。下面是一个示例： 178 | 179 | ```shell 180 | # 相当于--toolchain=loongarch64-linux-gnu-clang 181 | xmake f --toolchain=target-clang -a loong64 -p cross --target_os=linux 182 | ``` 183 | 184 | 使用`cross`平台并且不指定`--target_os`选项则会推导出独立工具链，下面是一个示例： 185 | 186 | ```shell 187 | # 推导出独立工具链，相当于--toolchain=arm-none-eabi 188 | xmake f --toolchain=target-clang -a arm -p cross 189 | ``` 190 | 191 | ### xmake文件说明 192 | 193 | xmake支持文件位于`xmake`文件夹下，下面是各个文件的说明： 194 | 195 | | 文件 | 说明 | 196 | | :------------------ | :-------------------------------------------------------------- | 197 | | option.lua | 提供各种xmake配置选项，包含`utility/utility.lua`文件 | 198 | | rule.lua | 提供4种常用xmake规则，包含`option.lua`文件 | 199 | | toolchain.lua | 提供各种xmake工具链，包含`option.lua`和`utility/target.lua`文件 | 200 | | utility/target.lua | 受支持的目标平台表，内部文件 | 201 | | utility/utility.lua | 提供各种配置工具，内部文件 | 202 | 203 | 其中`option.lua`可以单独使用，此时需要使用`add_options`来关联选项和目标。如果使用`toolchain.lua`中定义的工具链，这些选项会自动添加到相应工具链中。 204 | `utility/target.lua`可以通过`includes`函数引入到描述域中，此时函数和变量均可使用；也可以通过`import`函数引入脚本域，此时仅函数接口可用。 205 | 206 | ### xmake选项说明 207 | 208 | 下面是`option.lua`提供的xmake配置选项说明： 209 | 210 | - march 设置工具链的`-march`选项，默认为`default` 211 | 212 | | 选项 | 说明 | 213 | | :----- | :-------------------------------------------------------- | 214 | | no | 不添加`-march`选项 | 215 | | detect | 如果可以则添加`-march=native`选项，否则不添加`-march`选项 | 216 | | arch | 添加`-march=arch`选项，`arch`不能为`no`和`detect` | 217 | 218 | - sysroot 设置工具链的`--sysroot`选项，默认为`detect` 219 | 220 | | 选项 | 说明 | 221 | | :----- | :--------------------------------------------------------------------------- | 222 | | no | 不添加`--sysroot`选项 | 223 | | detect | 工具链为clang则自动探测sysroot，为gcc则不添加选项 $^*$ | 224 | | path | 添加`--sysroot=path`选项，`path`可以是绝对路径或不为`no`和`detect`的相对路径 | 225 | 226 | *：关于自动探测支持请参阅[sysroot说明](readme/sysroot.md#说明)。 227 | 228 | - rtlib 设置clang的`-rtlib`选项，默认为`default` 229 | 230 | | 选项 | 说明 | 231 | | :---------- | :-------------------------------------------------- | 232 | | default | 不添加`-rtlib`选项，即使用构建clang时指定的默认选项 | 233 | | libgcc | 添加`-rtlib=libgcc`，指定使用`libgcc` | 234 | | compiler-rt | 添加`-rtlib=compiler-rt`，指定使用`compiler-rt` | 235 | | platform | 添加`-rtlib=platform`，即使用目标平台的默认选项 | 236 | 237 | - unwindlib 设置clang的`-unwindlib`选项，默认为`default` 238 | 239 | | 选项 | 说明 | 240 | | :-------------- | :-------------------------------------------------------- | 241 | | default | 不添加`-unwind`选项，即使用构建clang时指定的默认选项 | 242 | | libgcc | 添加`-unwind=libgcc`，指定使用`libgcc` $^*$ | 243 | | libunwind | 添加`-unwind=libunwind`，指定使用`libunwind` $^*$ | 244 | | platform | 添加`-unwind=platform`，即使用目标平台的默认选项 $^*$ | 245 | | force_libgcc | 强制添加`-unwind=libgcc`，指定使用`libgcc` $^*$ | 246 | | force_libunwind | 强制添加`-unwind=libunwind`，指定使用`libunwind` $^*$ | 247 | | force_platform | 强制添加`-unwind=platform`，即使用目标平台的默认选项 $^*$ | 248 | 249 | *：为避免`argument unused`警告，默认情况下仅在`rtlib`选项为`compiler-rt`时添加该选项，可以使用force版本强制添加 250 | 251 | - debug_strip 设置在启用调试符号的规则中是否要剥离符号表，默认为`no` 252 | 253 | | 选项 | 说明 | 254 | | :---- | :----------------------------------------------------- | 255 | | no | 如果可能，不剥离任何符号 | 256 | | debug | 剥离调试符号到独立符号文件 | 257 | | all | 剥离调试符号到独立符号文件，然后去除目标文件中所有符号 | 258 | 259 | - enable_lto 设置在具有发布属性的规则（如`release`，`minsizerel`和`releasedbg`）中是否启用链接时优化（LTO），默认为`true` 260 | 261 | | 选项 | 说明 | 262 | | :---- | :------ | 263 | | true | 启用LTO | 264 | | false | 禁用LTO | 265 | 266 | 该选项在编译器与链接器不匹配时特别有用，因为此时需要禁用LTO才能正常完成构建流程。例如使用`clang`进行编译而使用`ld.bfd`进行链接，此时若启用LTO则会提示无法识别文件格式。 267 | 通常，`clang`使用`lld`进行链接，但如果`lld`不支持目标平台，则可能发生上述情况。使用该选项可以方便地根据需求设置或禁用LTO。 268 | 269 | ### xmake工具链说明 270 | 271 | 可以使用`xmake show -l toolchains`命令查看所有受支持的工具链名称，具体工具链的信息可以参阅[受支持的工具链](#工具链)。 272 | 工具链的命名规则和说明如下： 273 | 274 | | 名称 | 说明 | 275 | | :---------- | :-------------------------------------------------------------------------------------- | 276 | | native-tool | 本地工具链，对于clang不会添加`--target`选项，对于gcc会查找`gcc`工具 | 277 | | target-tool | 根据xmake的`arch`和`plat`选项自动推导出目标平台工具链 | 278 | | plat-tool | 目标平台为plat的工具链，对于clang会添加`--target=plat`选项，对于gcc会查找`plat-gcc`工具 | 279 | 280 | 注解：`tool`表示工具链类型，为`clang`或`gcc` 281 | 282 | xmake工具链还会根据目标平台的特性添加一些选项，如为`loongarch64-loongnix-linux-gnu`平台添加`-Wl,-dynamic-linker=/lib64/ld.so.1`选项以修改动态库加载器路径。 283 | -------------------------------------------------------------------------------- /build_llvm.md: -------------------------------------------------------------------------------- 1 | # 构建LLVM工具链 2 | 3 | ## 基本信息 4 | 5 | | 项目 | 版本 | 6 | | :--- | :----------- | 7 | | OS | Ubuntu 24.10 | 8 | | LLVM | 20.0.0 | 9 | | GCC | 16.0.0 | 10 | 11 | ## 准备工作 12 | 13 | ### 1.安装系统包 14 | 15 | ```shell 16 | # 使用clang自举 17 | sudo apt install git python3 cmake ninja-build clang lld libxml2-dev zlib1g-dev 18 | ``` 19 | 20 | ### 2.准备sysroot 21 | 22 | 作为一个交叉编译器，clang需要设置sysroot来查找所需的库和头文件，值得注意的是，clang不适用multilib，故而需要为32位目标和64位目标分别制作sysroot。 23 | 一个平台的sysroot需要包含如下内容： 24 | 25 | | 内容 | 说明 | 26 | | ------------ | ---------------------- | 27 | | Linux Header | 内核头文件 | 28 | | libc | C 标准库 | 29 | | libgcc | 提供异常处理等底层功能 | 30 | | libstdc++ | C++ 标准库 | 31 | | ldscripts | 链接器脚本 | 32 | 33 | 故而制作一个sysroot需要用到如下项目： 34 | 35 | | 项目 | 说明 | 36 | | -------------------------------------- | --------------------------------------- | 37 | | Linux | 提供内核头文件 | 38 | | Glibc/Mingw-w64 | 提供C 标准库 | 39 | | gcc | 提供libgcc和C++ 标准库 | 40 | | binutils | 提供链接器脚本 | 41 | | compiler-rt/libunwind/libcxx/libcxxabi | 在完成LLVM工具链编译后用于替代GNU相关库 | 42 | 43 | 对于一个安装在`prefix`并且交叉到`target`平台的交叉工具链，在`prefix/target`目录下可以找到`include`、`lib`、`lib64`等文件夹，而在`prefix/lib/gcc`可以找到libgcc相关文件夹， 44 | 其中已经包含了sysroot所需的全部文件。对于一个本地工具链，由于系统相关的库和头文件安装在系统目录下，故本地工具链本身仅带有gcc和binutils相关文件， 45 | 而linux和libc相关文件需要自行安装，安装流程可以参考[build_gcc.md](build_gcc.md)中的说明。 46 | 47 | 故而制作一个sysroot的流程如下： 48 | 49 | | 平台 | 流程 | 50 | | ---------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | 51 | | 非host平台 | 直接从`prefix/target`目录下复制`include`、`lib`、`lib64`（如果存在）文件夹 | 52 | | host平台 | 首先安装Linux头文件和libc文件，然后从`prefix`目录下复制`include`、`lib32/64`（取决于host的性质，复制成lib文件夹），再从`prefix/host/lib`下复制`ldscripts` | 53 | | 通用 | 从`prefix/lib`下复制`gcc`文件夹 | 54 | 55 | 对于启用multilib编译的gcc，在制作sysroot时需要视作两个目标处理。例如对于启用了multilib的`x86_64-linux-gnu-gcc`，制作sysroot时需要拆分成`x86_64-linux-gnu`和`i686-linux-gnu`两个目标。 56 | 故而在编译gcc时也可以选择不启用multilib来简化sysroot的制作流程。 57 | 58 | 一个sysroot的目录结构实例如下： 59 | 60 | ```txt 61 | sysroot 62 | ├── aarch64-linux-gnu 63 | ├── i686-linux-gnu 64 | ├── i686-w64-mingw32 65 | ├── lib 66 | │

83 | 84 | 通过clang自举出不依赖gnu相关库的完整llvm工具链需要分为4个阶段进行： 85 | 86 | 1. 第一次编译llvm及runtimes，依赖gnu相关库 87 | 2. 使用刚才编译的llvm和runtimes重新编译llvm，得到不依赖gnu相关库的llvm 88 | 3. 使用刚才编译的llvm和runtimes重新编译runtimes，得到不依赖gnu相关库的runtimes 89 | 4. 打包工具链 90 | 91 | 上述流程共计需要编译llvm部分2次，runtimes部分2次，为缩短构建流程可跳过一些自举步骤。 92 | 如果无需自举llvm，则可以跳过[再次编译llvm](#2再次编译llvm)，并且可以按需在[首次编译llvm](#1首次编译llvm以及runtimes)流程中启用`clang-tools-extra`组件和LTO优化； 93 | 如果无需自举runtimes，则可以跳过[再次编译runtimes](#3再次编译runtimes)。 94 | 95 | #### (1)首次编译llvm以及runtimes 96 | 97 | 首先编译llvm： 98 | 99 | ```shell 100 | export llvm_prefix=~/x86_64-linux-gnu-clang20 101 | export runtimes_prefix=$llvm_prefix/install 102 | export

143 | 144 | 接下来编译所有需要的runtimes，值得注意的是，在Windows上尚不支持使用动态链接的libcxxabi，故而需要改用静态链接的libcxxabi作为libcxx的abi实现。这需要增加 145 | `-DLIBCXXABI_ENABLE_SHARED=OFF`和`-DLIBCXX_ENABLE_STATIC_ABI_LIBRARY=ON`选项。参见[GitHub Issue](https://github.com/llvm/llvm-project/issues/62798)。 146 | 而编译runtimes需要较新的Linux header和Glibc，故而不能为`loongarch64-loongnix-linux-gnu`等老旧目标编译runtimes。 147 | 同时在为arm平台编译runtimes时需要armv6+的配置才能完成编译，故而需要为`$flags`增加`-march=armv6`选项。 148 | 149 | ```shell 150 | # 静态构建libcxxabi 151 | export llvm_option_list_w32_1="$llvm_option_list1 -DLIBCXXABI_ENABLE_SHARED=OFF -DLIBCXX_ENABLE_STATIC_ABI_LIBRARY=ON" 152 | # 进入llvm项目目录 153 | cd ~/llvm 154 | # 配置runtimes 155 | cmake -G Ninja --install-prefix $runtimes_prefix -B build-x86_64-linux-gnu-runtimes -S runtimes

在编译完runtimes后还需要将llvm相关库复制到sysroot下，以便在后续使用过程中通过命令行选项切换使用的库，以及编译出不依赖gnu相关库的llvm。 185 | 值得注意的是，compiler-rt相关库需要复制到`prefix/lib/clang/version`而不是sysroot下。同时，对于Windows平台而言，dll位于`bin`目录下，而对于 186 | Linux平台而言，so位于`lib`目录下。最后，在安装带runtimes的llvm时会安装一份libcxx的头文件到`prefix/include/c++/v1`下，此部分头文件是跨平台的， 187 | 但在编译Windows平台的程序时，clang不会在`prefix/include`路径下查找，故还需要复制一份到sysroot下，但该过程只需要进行一次即可。 188 | 而libcxx中与平台相关的部分储存在`__config_site`文件中，故该文件需要复制到sysroot下。 189 | 下面以复制`x86_64-linux-gnu`相关的库为例： 190 | 191 | ```python 192 | import os 193 | import shutil 194 | 195 | def overwrite_copy(src: str, dst: str): 196 | """复制文件或目录，会覆盖已存在项 197 | 198 | Args: 199 | src (str): 源路径 200 | dst (str): 目标路径 201 | """ 202 | if os.path.isdir(src): 203 | if os.path.exists(dst): 204 | shutil.rmtree(dst) 205 | shutil.copytree(src, dst) 206 | else: 207 | if os.path.exists(dst): 208 | os.remove(dst) 209 | shutil.copyfile(src, dst, follow_symlinks=False) 210 | 211 | home = os.path.expanduser("~") 212 | prefix = f"{home}/x86_64-linux-gnu-clang20/install" 213 | sysroot = f"{home}/sysroot" 214 | compiler_rt = f"{home}/x86_64-linux-gnu-clang20/lib/clang/20/lib" 215 | for dir in os.listdir(prefix): 216 | src_dir = os.path.join(prefix, dir) 217 | match dir: 218 | case "lib": 219 | dst_dir = os.path.join(sysroot, target, "lib") 220 | if not os.path.exists(compiler_rt): 221 | os.mkdir(compiler_rt) 222 | for item in os.listdir(src_dir): 223 | # 复制compiler-rt 224 | if item == "linux": 225 | item = item.lower() 226 | rt_dir = os.path.join(compiler_rt, item) 227 | if not os.path.exists(rt_dir): 228 | os.mkdir(rt_dir) 229 | for file in os.listdir(os.path.join(src_dir, item)): 230 | overwrite_copy(os.path.join(src_dir, item, file), os.path.join(rt_dir, file)) 231 | continue 232 | # 复制其他库 233 | overwrite_copy(os.path.join(src_dir, item), os.path.join(dst_dir, item)) 234 | case "include": 235 | # 复制__config_site 236 | dst_dir = os.path.join(sysroot, target, "include") 237 | overwrite_copy(os.path.join(src_dir, "c++", "v1", "__config_site"), os.path.join(dst_dir, "__config_site")) 238 | # 只要复制一次即可 239 | src_dir = os.path.join(prefix, "include", "c++") 240 | dst_dir = os.path.join(sysroot, "include", "c++") 241 | overwrite_copy(src_dir, dst_dir) 242 | ``` 243 | 244 | #### (2)再次编译llvm 245 | 246 | 此次只编译llvm及子项目，不编译runtimes，但可以启用`clang-tools-extra`等额外的子项目。 247 | 248 | 为了实现全面的llvm化，可以将clang默认的库设置成llvm相关库而不是gnu相关库，以实现运行库的替换。它们的关系如下： 249 | 250 | | gnu | llvm | 251 | | ------------ | ------------------------------- | 252 | | libsanitizer | compiler-rt | 253 | | libgcc | compiler-rt+libunwind+libcxxabi | 254 | | libstdc++ | libcxx | 255 | 256 | 使用选项`-stdlib=libc++`，`-unwindlib=libunwind`和`-rtlib=compiler-rt`即可将clang使用的运行库切换到llvm相关库上。 257 | 258 | 下面是再次编译llvm的相关选项（一些重复选项的说明请参阅[首次编译流程](#1首次编译llvm以及runtimes)： 259 | 260 | ```shell 261 | # 重复部分参考llvm_option_list1 262 | # 增加子项目：clang-tools-extra 263 | # 开启LTO以提升性能 264 | #

如果是自举编译，即完成了[再次编译llvm](#2再次编译llvm)流程，那么此时的clang默认就是使用llvm相关库，反之clang依然使用gnu相关库。 286 | 那么需要向`$flags`中额外增加`-stdlib=libc++ -unwindlib=libunwind -rtlib=compiler-rt`选项以切换构建时使用的库。 287 | - 尽管已经完成了llvm相关库的构建，在编译Windows目标时依然需要依赖libgcc来提供`___chkstk_ms`等函数，故而需要向`$flags`中额外增加`-lgcc`选项，但这不会引入对`libgcc`动态库的依赖。 288 | - 尽管使用了llvm相关库代替gnu相关库，但个别链接库如`libclang_rt.asan-x86_64.so`依然会依赖`libgcc_s.so.1`，没有完全脱离gnu相关库。 289 | 290 | #### (4)打包工具链 291 | 292 | 到此为止，一个完整的llvm工具链就完成了构建和组装。下面对工具链的两部分进行打包。 293 | 294 | ```shell 295 | cd ~ 296 | tar -cf x86_64-linux-gnu-clang20.tar x86_64-linux-gnu-clang20 297 | tar -cf sysroot.tar sysroot 298 | xz -ev9 -T 0 --memlimit=14GiB x86_64-linux-gnu-clang20.tar 299 | xz -ev9 -T 0
