What's interesting (to me at least) is "oh right, the spec for this only says abs-diff less than 1.5 x 2^-12 or something" and that AMD and Intel parts may diff

What's interesting (to me at least) is "oh right, the spec for this only says abs-diff less than 1.5 x 2^-12 or something" and that AMD and Intel parts may differ by a lot (in the example post and value, the AMD part is more accurate).
- akkartik 5y agoYeah, for sure. I should just take it out of my project. I'm only supporting a subset of the instruction set anyway.
- boulos 5y agoYou're in good company though with the WASM folks. It does feel like you've strayed outside of your non-goal of Speed. Also though as a nit, there are double precision forms (e..g, VSQRTPD), so: > When it upgraded SSE to SSE2 (in 2000), most of its single-precision floating-point instructions got upgraded to double-precision — but not these two. isn't correct. It's still not likely that you needed to care about these for mu.
- akkartik 5y agoThank you for the correction! I had my blinkers on there and wasn't thinking of the vector instruction set.
