Xi Ruoyao <xry111 at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|0 |1 Last reconfirmed| |2025-03-21 Status|UNCONFIRMED |NEW --- Comment #4 from Xi Ruoyao <xry111 at gcc dot gnu.org> --- (In reply to Richard Biener from comment #1) > Q is an extension, 1.11111f128 should work. The extension is enabled only > for some platforms. The reason is we already added __float128 for "compatibility with existing code" so it makes sense to add Q as well. And we have "use a suffix ‘q’ or ‘Q’ for ‘__float128’" in https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html, to me it implies if __float128 is supported, q and Q should be supported too.
