Description Martin Liska 2022-09-30 09:23:01 UTC 
Right now, readelf can't read ZSTD compressed sections:

$ readelf -wi a.o
readelf: Warning: section '.debug_str' has unsupported compress type: 2
readelf: Warning: section '.debug_info' has unsupported compress type: 2

Also, the --decompress option decompresses section content.
