## YAML below is produced from the following code. AddressAlign of .debug_info is 8,
## while compressed header has ch_addralign = 1. LLD had a bug and did not use the
## value of ch_addralign at all. We produced broken section content.
##
## .section .debug_info,"",@progbits
##  .string "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
##  .string "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

## YAML below is the same as above, with a single change: ch_addralign field of the compressed
## header was set to 0. This is allowed by the standard, we have to support it.
