When a linker script alternates among 8# different types of output section in the same command, the sections are 9# reordered. 10# In this test we go from regular, to merge and back to regular. The reason 11# for the reordering is that we need two create two output sections and 12# one cannot be in the middle of another. 13# If this ever becomes a problem, some options would be: 14# * Adding an extra layer in between input section and output sections (Chunk). 15# With that this example would have 3 chunks, but only one output section. 16# This would unfortunately complicate the non-script case too. 17# * Just create three output sections. 18# * If having three output sections causes problem, have linkerscript specific 19# code to write the section table and section indexes. That way we could 20# keep 3 sections internally but not expose that. 21 22# CHECK: Name: abc 23# CHECK: 0000: 01000000 00000000 02000000 00000000 | 24# CHECK: Name: abc 25# CHECK: 0000: 61626331 323300 |abc123.| 26 27 .section foo, "a" 28 .quad 1 29 30 .section bar,"aMS",@progbits,1 31 .asciz "abc123" 32 33 .section zed, "a" 34 .quad 2 35
