23 This tests linker script behavior, that gold distinguishes correctly
28 in an input section spec. In the first case, the output section
29 should contain all .x1 sections, followed by all .x2 sections,
30 then all .x3 sections; i.e.:
31 script_test_12a.o(.x1)
32 script_test_12b.o(.x1)
33 script_test_12a.o(.x2)
34 script_test_12b.o(.x2)
35 script_test_12a.o(.x3)
36 script_test_12b.o(.x3)
38 In the second case, the output section should interleave the
39 .x1, .x2, and .x3 sections in the order seen; i.e.:
40 script_test_12a.o(.x1)
41 script_test_12a.o(.x2)
42 script_test_12a.o(.x3)
43 script_test_12b.o(.x1)
44 script_test_12b.o(.x2)
45 script_test_12b.o(.x3)
47 The linker scripts set the absolute symbol INTERLEAVED, which we
48 test here to determine which ordering to expect. The scripts also
49 define the symbols test_array_start and test_array_end.
