> And how does that solve the problem when Altivec is "supported"?
Let's first fix existing problems. :-) But a partial solution could be to make BIGGEST_ALIGNMENT depend on TARGET_ALTIVEC_ABI and later set TARGET_ALTIVEC_ABI unconditionally to 1 when Altivec support is added: #define BIGGEST_ALIGNMENT ((TARGET_32BIT && !TARGET_ALTIVEC_ABI) ? 64 : 128) That would actually be sufficient for Ada, as the biggest problem is the STACK_BOUNDARY vs BIGGEST_ALIGNMENT discrepancy. The Ada compiler does not run into the problem I talked about in my original message on Darwin because TARGET_ALTIVEC_ABI is set to 1 there, so STACK_BOUNDARY == BIGGEST_ALIGNMENT. -- Eric Botcazou
