## Show that llvm-readobj can dump SHT_LLVM_ADDRSIG sections.

## Check that llvm-readobj dumps any SHT_LLVM_ADDRSIG section when --all
## is specified for LLVM style, but not for GNU style.
## TODO: Refine the llvm-readelf check when GNU-style dumping is implemented.

## Check we report a warning when SHT_LLVM_ADDRSIG is broken (e.g. contains a malformed uleb128).

# RUN: yaml2obj --docnum=2 %s -o %t2.o
# RUN: llvm-readobj --addrsig %t2.o 2>&1 | FileCheck %s -DFILE=%t2.o --check-prefix=MALFORMED
