This is the sixth public release of the LLVM compiler infrastructure.

-

At this time, LLVM is known to correctly compile on a broad range of -C and C++ programs, including the SPEC CPU95 & 2000 suite. This release -includes several major enhancements to the LLVM system, including a new -PowerPC JIT, enhancements to the C/C++ front-end to provide source line number -information in LLVM, a new compiler -driver, and several other enhancements listed below. It also includes -bug fixes for those problems found since the 1.3 release.

Note that this release seperates the LLVM Program Testsuite out of the -main LLVM distribution into a seperate CVS repository and tarball. This -reduces the size of the main LLVM distribution. Also note that LLVM now -builds tools into llvm/Debug/bin by default instead of llvm/tools/Debug.

  1. LLVM now includes a Just-In-Time compiler for the PowerPC target.
    2. -
  2. llvmgcc and llvmg++ now emit source line number information when '-g' is - passed in, making it possible to map from LLVM code back to source. - This information is currently used by llvm-db and can be used with other - tools and passes.
    3. -
  3. The test/Programs hierarchy has - been moved out of the main LLVM tree into a separate CVS repository and - tarball. This shrinks the distribution size of LLVM itself significantly. -
    4. -
  4. LLVM now optimizes global variables more aggressively than it did - before.
    5. -
  5. LLVM now includes the new 'undef' value and - unreachable instruction, - which give the optimizer more information about the behavior of the - program. -
    6. -
  6. Bytecode compression with bzip2 has been implemented. All bytecode files - generated by LLVM will now be compressed by default. Compression can be - disabled with the -disable-compression option to the tools that can - generate bytecode files. -
    7. -
  7. A generic compiler driver - (llvmc) and - an associated generic linker - (llvm-ld) have been added. The compiler driver is generic because it can be - configured - to pre-process, translate, optimize, assemble, and link code from any source - language with an LLVM front-end. This makes it easier for compiler writers - to hide the multiple steps required to compile a program (compiling, - optimizing, linking runtime libraries, etc) in one simple command. -
    8. -
  8. The dependent libraries - feature has been implemented. This allows front end compilers to indicate in - the bytecode which libraries the bytecode needs to be linked with. Both the - C/C++ and Stacker front ends support generating the required dependencies. - The linker now supports using this information to ensure required libaries are - linked into the module. This minimizes the need to use the -l option - when using llvmc. -
    9. -
  9. The LLVM makefiles have been improved to build LLVM much faster and - includes new targets (like dist-check, uninstall). One important user-visible - change is that libraries and tools will now be built into - $builddir/Debug/{bin,lib} - instead of $builddir/tools/Debug and $builddir/lib/Debug - (Similarly for Release and Profile builds). -
    10. -
  10. The LLVM source code is much more compatible with Microsoft Visual C++, - including the JIT and runtime-code generation, though the entire system - may not work with it. -
    11. -
  11. The JIT-Target interfaces are - now much simpler and more powerful. -
    12. -
  12. LLVM now provides llvm-ar and llvm-ranlib tools for working with archives - of LLVM bytecode files.
    13. -
  13. zlib and libpng are no longer - included in the main LLVM tarball.
    14. -
  14. The LLVM code generator now automatically generates assembly code writers - from an abstract target descriptions, eliminating the need to write - assembly printers manually.
