## Test how obj2yaml emits relocation addend descriptions.
|
||
|
|
## We document that relocation addends are dumped as signed int64 decimal values.
|

|
|
|

|
|
## Case 1: Check a 64-bit object.
|
||
|

## Check how obj2yaml dumps an addend with an arbitrary positive value.
|
||
|
|
## We use 1 as it is the first possible positive value.
