42 <para>
43 The <application>LLVM</application> package contains a collection of
44 modular and reusable compiler and toolchain technologies. The Low Level
45 Virtual Machine (LLVM) Core libraries provide a modern source and
46 target-independent optimizer, along with code generation support for many
47 popular CPUs (as well as some less common ones!). These libraries are
48 built around a well specified code representation known as the LLVM
49 intermediate representation ("LLVM IR").

52 <para>
53 The optional <application>Clang</application> and <application>Compiler
54 RT</application> packages provide new C, C++, Objective C and Objective
55 C++ front-ends and runtime libraries for the
56 <application>LLVM</application> and are required by some packages which
57 use <application>Rust</application>, for example
58 <application>firefox</application>.

222 by the <systemitem class="username">root</systemitem> user and makes them
223 temporarily unusable by all jobs on the machine.)

273
274 <para>
275 <parameter>-DLLVM_ENABLE_FFI=ON</parameter>: This switch enables
276 <application>LLVM</application> to use
277 <application>libffi</application>.
278 </para>
279
280 <para>
281 <parameter>-DLLVM_BUILD_LLVM_DYLIB=ON</parameter>: builds libraries as
282 static and links all of them into an unique shared one. This is the
283 recommended way of building a shared library.
284 </para>
285
286 <para>
287 <parameter>-DCMAKE_BUILD_TYPE=Release</parameter>: This switch enables
288 compiler optimizations in order to speed up the code and reduce its size.
289 It also disables some compile checks, not necessary on a production
290 system.
291 </para>
292
293 <para>
294 <parameter>-DLLVM_TARGETS_TO_BUILD="host;AMDGPU;BPF"</parameter>: This
295 switch enables building for the same target as the host, and also for
296 the r600 AMD GPU used by the Mesa r600 and radeonsi drivers. The BPF
297 target is required to build <xref linkend="v4l-utils"/>. Default is
298 all. You can use a semicolon separated list. Valid targets are: host,
299 X86, Sparc, PowerPC, ARM, AArch64, Mips, Hexagon, Xcore, MSP430, NVPTX,
300 SystemZ, AMDGPU, BPF, CppBackend, or all.
301 </para>
302
303 <para>
304 <parameter>-DLLVM_LINK_LLVM_DYLIB=ON</parameter>: Used in conjunction with
305 <parameter>-DLLVM_BUILD_LLVM_DYLIB=ON</parameter>, this switch enables
306 linking the tools against the shared library instead of the static ones.
307 It also slightly reduces their size and also ensures that llvm-config
308 will correctly use libLLVM-&llvm-majmin;.so.
309 </para>
310
311 <para>
312 <parameter>-D=LLVM_ENABLE_RTTI=ON</parameter>: Used to build LLVM with
313 run-time type information. This is required for building
314 <xref linkend="mesa"/>.
315 </para>
316
317 <para>
318 <option>-DBUILD_SHARED_LIBS=ON</option>: if used instead of
319 <parameter>-DLLVM_BUILD_LLVM_DYLIB=ON</parameter> and
320 <parameter>-DLLVM_LINK_LLVM_DYLIB=ON</parameter>, builds all the
321 <application>LLVM</application> libraries (about 60) as shared
322 libraries instead of static.
323 </para>
324
325 <para>
326 <option>-DLLVM_ENABLE_DOXYGEN</option>: Enables the generation of
327 browsable HTML documentation if you have installed <xref
328 linkend="doxygen"/>. You should run <command>make doxygen-html</command>
329 afterwards, and install the generated documentation manually.
