That's not true, LTO creates a faster binaries with LTO. Of course it does, I'm just suspecting it won't be much faster. I'm not doubting the merits of LTO, although I personally prefer Clang's ThinLTO because of the smaller resource usage, and I hope that GCC will offer something similar sometime in the future.
In addition, LLVM builds already take very long, and even just ThinLTO is going to make that worse.
For now, I would not make the build even longer.
I'm not sure if the "lamb" machines all have the same hardware, but the current build in devel:tools:compiler takes ~10000s, while with ThinLTO it takes ~15000s. I should compare the build times on the same machine though to be sure. -- You are receiving this mail because: You are on the CC list for the bug.
