# Show that llvm-readobj prints symbol shndxes correctly, for valid indexes,
|
|
# invalid indexes (i.e. section indexes that don't correspond to a real
|
|
# section), reserved values and processor/os-specific index values, for both GNU
|
|
# and LLVM styles.
|
|
|
|
# Use --dyn-symbols because yaml2obj does not currently support large section indexes
|
|
# and also does not allow hand-crafting of static symbol tables.

# llvm-readobj doesn't accept shndx values that are not valid section indexes
|
|
# for LLVM style, so only test GNU output in this case.
