> LTO was available in llvm forever, and well predates GCC, clang is just a particular frontend. For the initial version of this guide, I chose to focus on features as they are exposed in specific tools, as it's easier to pin down a "first available" date that way. Basic LTO for Clang is listed as first available in Clang 2.6, which is also the first LLVM release to officially include Clang. > It also misses the function summary vs non summary modes, which is fairly important. Are you talking about the module summaries LLVM uses in its parallel / thin LTO mode, or something else? |
