GCC 4.8.0 is being released, adjusting target milestone. GCC 4.8.1 has been released. GCC 4.8.2 has been released. Forgive my ignorance... Is __builtin_cpu_supports really __builtin_os_supports? If we want to test CPU support (rather than OS support), then can it be done with the built-ins? Also, the documentation at https://gcc.gnu.org/onlinedocs/gcc-4.8.2/gcc/X86-Built-in-Functions.html does not mention that this is in fact OS support, and not CPU support. This was fixed in #85100. Dup. |
