## In this test, we check how llvm-objcopy handles compression/decompression
## of debug sections included in a COMDAT group.

# RUN: yaml2obj %p/Inputs/compress-debug-sections.yaml -o %t.o

## Check compression of debug sections.

## Check decompression of debug sections.
# RUN: llvm-objcopy --decompress-debug-sections %t-compressed.o %t-decompressed.o
