Commit 759be3dad9 bumped our Go
requirement to 1.18 which allows us to drop support for old-style
`+build` tags. This change runs `go fix ./...` to remove them, and
updates some remaining code generators that produced `+build` lines.
ext
Demonstrates how to use external types in an avo function signature.
In this case, you will need to write the function stub yourself.
package ext
import "github.com/mmcloughlin/avo/examples/ext/ext"
// StructFieldB returns field B.
func StructFieldB(e ext.Struct) byte
Then in place of the usual TEXT declaration we use Implement to state that we are beginning the definition of a function already declared in the package stub file.
Package("github.com/mmcloughlin/avo/examples/ext")
Implement("StructFieldB")
b := Load(Param("e").Field("B"), GP8())
Store(b, ReturnIndex(0))
RET()
Finally, in this case the go:generate line is different since we do not need to generate the stub file.
//go:generate go run asm.go -out ext.s
