BOLT (Binary Optimization and Layout Tool) is a Linux command-line utility that optimizes the performance of native binaries by rearranging code layout post-linking. This archived repository has been merged into the LLVM project, where development continues.
Use cases
- optimize performance of compiled binaries
- improve instruction cache locality of executables
- reorder code layout after linking
- speed up large C++ applications without recompiling
- profile-guided binary post-link optimization
When to choose
- you want to optimize an existing binary's code layout without source changes
- you have LBR perf profiles and want faster instruction cache/i-TLB behavior
- you are already in the LLVM ecosystem and can use the maintained bolt in llvm-project
When to avoid
- you need updates or bug fixes - this repo is frozen and unmaintained
- you target platforms other than Linux x86-64/aarch64 ELF binaries
- you want a general-purpose compiler or linker rather than a post-link optimizer
