Overview ¶
Package cpu detects the CPU features that sha1cd dispatches on.
It covers only what the assembly implementations need, which keeps start up cheap and avoids an external dependency. Every flag is false where a feature cannot be detected safely, which selects the generic implementation.

var ARM64 struct { HasSHA1 bool }
ARM64 holds the features of the current arm64 CPU. All flags are false on other architectures.

var X86 struct { // HasAVX and HasAVX2 are set only when the OS also preserves the YMM // state, and HasAVX512F only when it preserves the ZMM and opmask state. HasAVX bool HasAVX2 bool HasAVX512F bool HasBMI1 bool HasBMI2 bool HasSHA bool HasSSSE3 bool HasSSE41 bool }
X86 holds the features of the current amd64 CPU. All flags are false on other architectures.
