5 Proposal: Register-based Go calling convention

go.googlesource.com posted by kenny 1349 days ago  

We propose switching the Go ABI from its current stack-based calling convention to a register-based calling convention. Preliminary experiments indicate this will achieve at least a 5–10% throughput improvement across a range of applications. This will remain backwards compatible with existing assembly code that assumes Go’s current stack-based calling convention through Go’s multiple ABI mechanism.
