test/tools/llvm-readobj/elf-symbol-shndx.test

# 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.
# RUN: yaml2obj --docnum=1 %s > %t1
# RUN: llvm-readobj --symbols --dyn-symbols %t1 | FileCheck %s --check-prefix=LLVM
# RUN: llvm-readelf --symbols --dyn-symbols %t1 | FileCheck %s --check-prefix=GNU1

# llvm-readobj doesn't accept shndx values that are not valid section indexes
# for LLVM style, so only test GNU output in this case.
# RUN: yaml2obj --docnum=2 %s > %t2
# RUN: llvm-readelf --symbols %t2 | FileCheck %s --check-prefix=GNU2
