ThinLTO: Scalable and Incremental LTO
ThinLTO was first introduced at EuroLLVM in 2015, with results shown from a prototype implementation within clang and LLVM. Since then, the design was reviewed through several RFCs, it has been implemented in LLVM (for gold and libLTO), and tuning is ongoing. Results already show good performance for a number of benchmarks, with compile time close to a non-LTO build. This blog post covers the back

Writing fast, processor-independent code using C++ and LLVM bitcode
Writing fast, processor-independent code using C++ and LLVM bitcode Using inline assem bly along with C/C++ code has long been the best choice for developers writing optimized code. However the approach had its shortcomings: - the need to write assem bly for each architecture - the use of inline assem bly hinders certain compiler optimizations (such as register allocation) But thanks to LLVM it is no
