# Test parsing and writing of x86_64 text relocations.

|
|
# The first step tests if the supplied mach-o file is parsed into the correct
|
|
# set of references. The second step verifies relocations can be round-tripped
|
|
# by writing to a new .o file, then parsing that file which should result in
|
|
# the same references.
