--- Comment #12 from Bruno Haible <bruno at clisp dot org> --- (In reply to Jakub Jelinek from comment #11) > Are there some other targets which say canonicalize NaNs on simple moves? No, it's only the flds, fldl, fldt instructions on x86 and x86_64. In my testing on other architectures, from m68k to loongarch64, I did not encounter this problem anywhere else.
