Previously people pointed out that a lot of the extra M1 stuff (like TSO, x87 FP) is already standardized and/or has shipped in other ARM chips.

- stephencanon 4y agox87 FP hasn’t been standardized or added to any ARM cpu. What was added is a mode where underflow is detected “after rounding” (as x86 SSE/AVX instructions use) rather than “before rounding” (what all ARM FP instructions default to).
