CHECK-LABEL doesn't have to match a line in the file uniquely. What happens is
that all the -LABEL directives are processed first, in order, subdividing the
input text into regions. Then the non-LABEL directives are processed within
their respective regions.
So you could have
CHECK-LABEL: DW_TAG
CHECK: DW_AT_name ("foo")
CHECK-LABEL: DW_TAG
CHECK: DW_AT_location
CHECK-LABEL: DW_TAG
which would search only the first tag for "foo" and only the second tag for the
location attribute.
