Should we proceed and change the ABI on > Solaris for GCC 14? I think so, yes: * Binary compatibility with the Studio compilers is pretty important IMO. * Even though the SCD wording isn't really clear, the intent seems to match what Studio cc does according to the colleague on the spec group Jakub cited. * There's no point in waiting beyond GCC 14, I believe: this will break compatiblity with GCC <= 13 no matter what. * Besides, Solaris is pretty quick picking up new GCC releases these days, so they'll bundle GCC 14.1.0 not long after it's released, so the benefit will be immediate. * I'm a tad uncertain about what to do on Linux/sparc64, though: while it mostly has followed the SCD, there are exceptions (e.g. sizeof (long double)) and no vendor compiler to be compatible with. So making the same change there would only mean breaking compatibility with older GCCs (and clang) for little gain.
