[go-nuts] Re: Disable AVX, AVX2, AVX-512, SSE support while building a go binary
See https://github.com/golang/go/wiki/MinimumRequirements#amd64 The default is GOAMD64=v1 so the fancy extensions are disabled by default (or guarded).

It doesn't use a single channel of events to drive the pause behaviour because pause is not a toggle in this system (for safety), so it's less elegant in that sense, but it does require the consideration of the hold, release and the context.Done chans. https://go.dev/play/p/uyuP94Tvi50 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Re: Disable AVX, AVX2, AVX-512, SSE support while building a go binary
Note that SSE2 is not optional and is used for floating point operations on 386 and AMD64. Before 1.16 there has been a GO386 option that supported 387 instructions but it has been removed. GOAMD64 has no influence on it.

[go-nuts] Re: Disable AVX, AVX2, AVX-512, SSE support while building a go binary
After reading the documentation I have to correct. GO386 supports the softfloat option to support older processors which don't support SSE2.
