# REQUIRES: zlib

## 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.
# RUN: llvm-objcopy --compress-debug-sections %t.o %t-compressed.o
# RUN: llvm-readobj -s -elf-section-groups %t-compressed.o | \
# RUN:   FileCheck %s --check-prefixes=CHECK,COMPRESS

## Check zlib-gnu compression of debug sections.
# RUN: llvm-objcopy --compress-debug-sections=zlib-gnu %t.o %t-compressed-gnu.o
# RUN: llvm-readobj -s -elf-section-groups %t-compressed-gnu.o | \
# RUN:   FileCheck %s --check-prefixes=CHECK,COMPRESSZLIB

## Check decompression of debug sections.
# RUN: llvm-objcopy --decompress-debug-sections %t-compressed.o %t-decompressed.o
# RUN: llvm-readobj -elf-section-groups %t-decompressed.o | \
# RUN:   FileCheck %s --check-prefixes=CHECK,DECOMPRESS

## Check decompression of zlib-gnu debug sections.
