Not usually; `float` is 32 bits and `double` is 64 bits on virtually every common platform (maybe not on some DSP chips or certain embedded chips?). But the C++ standard (and probably the C one) only requires that `double` have at least as

What are you referring to by "a ton of toolchain-specific hackery" and "a portable way to get LTO working"? It seems like there are very specific things you have in mind, but I'm unclear what bits of work you'

We saw significant performance gains when moving from GCC (6) to clang (6). I don't think it'd be particularly hard to switch back at this point; this article provides some solid data for doing so.

GCC is very close to the 30-year mark (0.9 released 22 March 1987). Linux turned 25 this past year; Firefox (the C++ parts, at least) is very close to 25, depending on what code you want to count. Apache is 20ish years old. Even LLVM, wh

Microsoft's PGO/LTCG implementation does just this. GCC can do something similar as well.
