1## This is a general test for --symbols option and its aliases.2## There are also other symbols* tests that check specific things.3 4## For testing and behavior documenting purposes we are using ET_REL and ET_DYN inputs.5## Relocatable ELF objects are very different by nature from executables and dynamic libraries.6## They might never have dynamic symbols normally, for example, though we still want7## to document the --dyn-symbols behavior.8## There is no need to check ET_EXEC inputs because for dumpers there is no difference9## between them and ET_DYN inputs in the context of this test.10 11## Case 1: Test how llvm-readobj and llvm-readelf dumps symbols.12## a) Check relocatable objects.13# RUN: yaml2obj %s -DBITS=64 -DTYPE=ET_REL -o %t6414# RUN: llvm-readobj --symbols %t64 |
