I thought LTO would reduce size by detecting more unused code. The bindist .tar.xz archives are as follows: LTO=Off: 195MB LTO=On : 953MB Now, I am of course aware that falling back to gcc's lto support is not the same as llvm's lto or thinlto, but I only fell back after it failed to build that way, and I wasn't aware of gcc6 providing almost 5x large code than without lto. Also, given a fresh 3.9 install, on an otherwi...
