Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target|x86_64-*-*, i?86-*-* |x86_64-*-*, i?86-*-*, | |aarch64, alpha, arm, ia64, | |loongarch, mips, sparc Keywords| |documentation --- Comment #18 from Richard Biener <rguenth at gcc dot gnu.org> --- I'll note that I can't find any documentation for this link-time behavior which triggers for -Ofast, -ffast-math and -funsafe-math-optimizations but also with -ffast-math -fno-unsafe-math-optimizations. I've adjusted the list of affected targets. What their crtfastmath.o actually does would need to be determined, but it for sure will have the same spreading effect.
