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