asmgen

Command gen produces sum_amd64.s, the SSE2 float64 kernels, via go-asmgen.

Command gen produces sum_arm64.s, the NEON float64 sum-reduction kernel, via go-asmgen.

Command gen produces sum_loong64.s, the LASX float64 kernels for loong64, via go-asmgen.

Command gen produces sum_ppc64le.s, the VSX float64 kernels for ppc64le, via go-asmgen.

Command regen runs every architecture's generator and moves its output into the kernels package: the native equivalent of the per-arch go:generate lines, which `go generate` only reaches for the host GOARCH.

Command gen produces sum_riscv64.s, the RVV (vector extension) float64 kernels for riscv64, via go-asmgen.

Command gen produces sum_s390x.s, the vector-facility float64 kernels for s390x, via go-asmgen.
