xref: /llvm-project/llvm/test/tools/llvm-readobj/ELF/symbol-visibility.test (revision 93c1a5f3ddd41e0ec09f38ab0045bd5e92199fd5) 
1## Show that llvm-readobj prints the symbol visibility where recognised, or
2## something sensible when not, for both GNU and LLVM output.
3
4## Check how we dump symbols when they have only STV_* bits set for st_other.
5## (This is the most common case).
