When a linker script alternates among # different types of output section in the same command, the sections are # reordered. # In this test we go from regular, to merge and back to regular. The reason # for the reordering is that we need two create two output sections and # one cannot be in the middle of another. # If this ever becomes a problem, some options would be: # * Adding an extra layer in between input section and output sections (Chunk). # With that this example would have 3 chunks, but only one output section. # This would unfortunately complicate the non-script case too. # * Just create three output sections. # * If having three output sections causes problem, have linkerscript specific # code to write the section table and section indexes. That way we could # keep 3 sections internally but not expose that. # CHECK: Name: abc # CHECK: 0000: 01000000 00000000 02000000 00000000 | # CHECK: Name: abc # CHECK: 0000: 61626331 323300 |abc123.| .section foo, "a" .quad 1 .section bar,"aMS",@progbits,1 .asciz "abc123" .section zed, "a" .quad 2
