Considering -fgnu-tm has been broken for LTO ever since LTO was introduced, and broken with -fsanitize=undefined and broken with many code that might use internal functions (known since 2015), I suspect nobody is using this option in production nor even trying it out. If this was stage1, I might even just recommend removing the support. But deprecating it during stage 3 seems like a fair compromise. > Eric Gallager
