18 In this tutorial we will first build Clang with PGO and LTO, and then will show steps on how to
27 on how to obtain and build Clang in [Bootstrapping Clang-7 with PGO and LTO](#bootstrapping-clang-7-with-pgo-and-lto) section.
35 We will use the setup described in [Bootstrapping Clang-7 with PGO and LTO](#bootstrapping-clang-7-with-pgo-and-lto).
106 `clang-7.bolt` can be used as a replacement for *PGO+LTO* Clang:
121 That's 22.61 seconds (or 12%) faster compared to the *PGO+LTO* build.
124 If we run BOLT on a Clang binary compiled without *PGO+LTO* (in which case the build is finished in 253.32 seconds),
126 but, as expected, the result is still slower than *PGO+LTO+BOLT* build.
159 On our 48-core Haswell system using the *PGO+LTO* Clang, the build finished in 136.06 seconds, while using the *PGO+LTO+BOLT* Clang, 126.10 seconds.
168 using the `merge-fdata` utility that comes with BOLT. Optimized with that profile, the *PGO+LTO+BOLT* Clang was able
