I believe all the dg-output directives just concatenate their regexps
together.
dg-output after the target handling in there just does
if { [llength ${output-text}] == 1 } {
# First occurrence.
set output-text [list $expected [lindex $args 1]]
} else {
set output-text [list $expected "[lindex ${output-text} 1][lindex $args
1]"]
}
Which is why matching those line separators is important, just doing
*> { dg-output "foo" }
*> { dg-output "bar" }
would only match foobar, not foo on one line and bar on another one.
