s390: Use long branches across object boundaries (jgh instead of jh)
|
|
|
6c0556 |
|
|
|
6c0556 |
Depending on the layout chosen by the linker, the 16-bit displacement
|
|
|
6c0556 |
of the jh instruction is insufficient to reach the target label.
|
|
|
6c0556 |
|
|
|
6c0556 |
Analysis of the linker failure was carried out by Nick Clifton.
