Here is the proposal: https://github.com/golang/go/issues/56378 They are documented here: https://pkg.go.dev/cmd/cgo@master#hdr-Optimizing_calls_of_C_code This would have been very useful to fix https://github.com/tinygo-org/bluetooth/issues/176 in a nice way. That bug is now fixed in a different way using a wrapper function, but once this new noescape pragma gets included in TinyGo we could remove the workaround and use `#cgo noescape` instead.
