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

58 and for <application>rust</application> if that is built using the system

370
371 <para>
372 <parameter>-DLLVM_ENABLE_FFI=ON</parameter>: This switch allows
373 <application>LLVM</application> to use
374 <application>libffi</application>.
375 </para>
376
377 <para>
378 <parameter>-DLLVM_BUILD_LLVM_DYLIB=ON</parameter>: This switch builds
379 the libraries as static and links all of them into an unique shared one.
380 This is the recommended way of building a shared library.
381 </para>
382
383 <para>
384 <parameter>-DCMAKE_BUILD_TYPE=Release</parameter>: This switch enables
385 compiler optimizations in order to speed up the code and reduce its size.
386 It also disables some compile checks which are not necessary on a
387 production system.
388 </para>
389
390 <para>
391 <parameter>-DLLVM_TARGETS_TO_BUILD="host;AMDGPU;BPF"</parameter>: This
392 switch enables building for the same target as the host, and also for
393 the r600 AMD GPU used by the Mesa r600 and radeonsi drivers. The BPF
394 target is required to build <xref linkend="v4l-utils"/>. The Default is
395 all of the targets. You can use a semicolon separated list. Valid targets
396 are: host, X86, Sparc, PowerPC, ARM, AArch64, Mips, Hexagon, Xcore,
397 M68K, MSP430, NVPTX, SystemZ, AMDGPU, BPF, CppBackend, or all.
398 </para>
399
400 <para>
401 <parameter>-DLLVM_LINK_LLVM_DYLIB=ON</parameter>: Used in conjunction with
402 <parameter>-DLLVM_BUILD_LLVM_DYLIB=ON</parameter>, this switch enables
403 linking the tools against the shared library instead of the static ones.
404 It slightly reduces their size and also ensures that llvm-config
405 will correctly use libLLVM-&llvm-maj-version;.so.
406 </para>
407
408 <para>
409 <parameter>-DLLVM_ENABLE_RTTI=ON</parameter>: This switch is used to
410 build LLVM with run-time type information. This is required for building
411 <xref linkend="mesa"/>.
412 </para>
413
414 <para>
415 <parameter>-DLLVM_BINUTILS_INCDIR=/usr/include</parameter>: This switch
416 is used to tell the build system the location of binutils headers,
417 which were installed in LFS. This allows the building of
418 <filename class="libraryfile">LLVMgold.so</filename>, which is needed
419 for building programs with <command>clang</command> and Link Time
420 Optimization (LTO).
421 </para>
422
423 <para>
424 <parameter>-DLLVM_INCLUDE_BENCHMARKS=OFF</parameter>:
425 is used to disable generation build targets for the LLVM
426 benchmarks. This option requires additional code that
427 is not currently available.
428 </para>
429
430 <para>
431 <parameter>-DCLANG_DEFAULT_PIE_ON_LINUX=ON</parameter>: makes
432 <option>-fpie</option> option the default when compiling programs.
433 Together with the <xref linkend="gASLR"/> feature enabled in the kernel,
434 this defeats some kind of attacks based on known memory layouts.
435 </para>
436
437 <para>
438 <option>-DBUILD_SHARED_LIBS=ON</option>: if used instead of
439 <parameter>-DLLVM_BUILD_LLVM_DYLIB=ON</parameter> and
440 <parameter>-DLLVM_LINK_LLVM_DYLIB=ON</parameter>, builds all the
441 <application>LLVM</application> libraries (about 60) as shared
442 libraries instead of static.
443 </para>
444
445 <para>
446 <option>-DLLVM_ENABLE_DOXYGEN</option>: Enables the generation of
447 browsable HTML documentation if you have installed <xref
448 linkend="doxygen"/>. You should run <command>make doxygen-html</command>
449 afterwards, and install the generated documentation manually.
