%general-entities; ]> $LastChangedBy$ $Date$ LLVM The LLVM package contains a collection of modular and reusable compiler and toolchain technologies. The Low Level Virtual Machine (LLVM) Core libraries provide a modern source and target-independent optimizer, along with code generation support for many popular CPUs (as well as some less common ones!). These libraries are built around a well specified code representation known as the LLVM intermediate representation ("LLVM IR"). The optional Clang and Compiler RT packages provide a new C, C++, Objective C and Objective C++ front-ends and runtime libraries for the LLVM. &lfs72_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &llvm-md5sum; Download size: &llvm-size; Estimated disk space required: &llvm-buildsize; Estimated build time: &llvm-time; Additional Downloads Required patch: Optional Downloads Clang Download (HTTP): Clang Download MD5 sum: &clang-md5sum; Clang Download size: &clang-size; Compiler RT Download (HTTP): Compiler RT Download MD5 sum: &compiler-rt-md5sum; Compiler RT Download size: &compiler-rt-size; LLVM Dependencies Recommended Optional , , , , OCaml, Sphinx and Valgrind User Notes: If you have downloaded the optional packages, install them into the source tree by running the following commands: tar -xf ../clang-&llvm-version;.src.tar.gz -C tools && tar -xf ../compiler-rt-&llvm-version;.src.tar.gz -C projects && mv tools/clang-&llvm-version;.src tools/clang && mv projects/compiler-rt-&llvm-version;.src projects/compiler-rt && sed -e "s@../lib/libprofile_rt.a@../lib/llvm/libprofile_rt.a@g" \ -i tools/clang/lib/Driver/Tools.cpp Install LLVM by running the following commands: patch -Np1 -i ../llvm-&llvm-version;-blfs_paths-1.patch && CC=gcc CXX=g++ \ ./configure --prefix=/usr \ --sysconfdir=/etc \ --libdir=/usr/lib/llvm \ --enable-libffi \ --enable-optimized \ --enable-shared \ --enable-targets=all \ --disable-assertions \ --disable-debug-runtime \ --disable-expensive-checks && make If you have installed Sphinx and wish to generate manual pages, issue the following command: make -C docs -f Makefile.sphinx man To test the results, issue: make check. Now, as the root user: make install && chmod -v 644 /usr/lib/llvm/*.a && echo /usr/lib/llvm >> /etc/ld.so.conf && ldconfig If you have built manual pages, install them by running the following command as the root user: install -m644 docs/_build/man/* /usr/share/man/man1 Installed Programs Installed Libraries Installed Directories bugpoint, c-index-test, clang, clang++, clang-check, clang-tblgen, llc, lli, llvm-ar, llvm-as, llvm-bcanalyzer, llvm-config, llvm-cov, llvm-diff, llvm-dis, llvm-dwarfdump, llvm-extract, llvm-link, llvm-mc, llvm-mcmarkup, llvm-nm, llvm-objdump, llvm-prof, llvm-ranlib, llvm-readobj, llvm-rtdyld, llvm-size, llvm-stress, llvm-tblgen, macho-dump and opt libclang.so, libLLVM-&llvm-version;.so, libprofile_rt.so and numerous libraries in /usr/lib/llvm /usr/include/clang, /usr/include/clang-c, /usr/include/llvm, /usr/include/llvm-c, /usr/lib/clang, /usr/lib/llvm and /usr/share/doc/llvm Short Descriptions bugpoint is the automatic test case reduction tool. bugpoint clang is the Clang C, C++, and Objective-C compiler. clang llc is the LLVM static compiler. llc lli is used to directly execute programs from LLVM bitcode. lli llvm-ar is the LLVM archiver. llvm-ar llvm-as is the LLVM assembler. llvm-as llvm-bcanalyzer is the LLVM bitcode analyzer. llvm-bcanalyzer llvm-config Prints LLVM compilation options. llvm-config llvm-cov is used to emit coverage information. llvm-cov llvm-diff is the LLVM structural 'diff'. llvm-diff llvm-dis is the LLVM disassembler. llvm-dis llvm-extract is used to extract a function from an LLVM module. llvm-extract llvm-link is the LLVM linker. llvm-link llvm-nm is used to list LLVM bitcode and object file's symbol table. llvm-nm llvm-prof is used to print execution profile of LLVM program. llvm-prof llvm-ranlib is used to generate index for LLVM archive. llvm-ranlib llvm-stress is used to generate random .ll files. llvm-stress llvm-tblgen is the LLVM Target Description To C++ Code Generator. llvm-tblgen opt is the LLVM optimizer. opt libLLVM-&llvm-version;.so contains the LLVM API functions. libLLVM-&llvm-version;.so libprofile_rt.so is the C, C++ and Objective-C runtime library for Clang. libprofile_rt.so
