What version of Go are you using (go version)?

go version devel +9398bda540 Thu Apr 1 10:29:51 2021 -0400 darwin/amd64

Does this issue reproduce with the latest release?

No, only on tip

What did you do?

GOARCH=ppc64le GOOS=linux go build  x.go

where x.go contains:

package x

import (
	"fmt"
)

type T struct {
	a map[int]int
}

func F(t T) {
	fmt.Print(t)
}

What did you expect to see?

Successful compilation

What did you see instead?

# command-line-arguments
./x.go:11:1: internal compiler error: 'F': not lowered: v19, Store SSA PTR STRUCT SSA
(etc)

This is caused by CL 305672 interacting badly with ppc64 code generation rules.
There's a fix on the way.
