the sync/atomic docs, https://golang.org/pkg/sync/atomic/, says in the end of the docs
On x86-32, the 64-bit functions use instructions unavailable before the > Pentium MMX. > On non-Linux ARM, the 64-bit functions use instructions unavailable before > the ARMv6k core. > > On both ARM and x86-32, it is the caller's responsibility to arrange for > 64-bit alignment of 64-bit words accessed atomically. > The first word in a global variable or in an allocated struct or slice can > be relied upon to be 64-bit aligned. > The last line says the first word in a global variable or in an allocated struct or slice is 64-bit aligned for sure. But what does an allocated struct or slice means? A struct or slice allocated on heap, not stack? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
