For i386, we are adding new target mask bits for new instruction sets. The new bits are used togther with existing ISA bits to selectively enable builtins. I don't know how to make the new variable to work when a new variable will have a set of bits overlapping with the exist ones. For example, SSE2 has #define MASK_SSE2 (1 << 21) But the new SSE4.1 will have something like #define OPTION_MASK_SSE4_1 (1 << 2) I can't use MASK_SSE2 | OPTION_MASK_SSE4_1 since 2 sets are different.
