Bug 428648 - s390x: Force 12-bit amode for vector loads in isel
|
|
|
|
Similar to Bug 417452, where the instruction selector sometimes attempted
|
|
to generate vector stores with a 20-bit displacement, the same problem has
|
|
now been reported with vector loads.
|
|
|
|
The problem is caused in s390_isel_vec_expr_wrk(), where the addressing
|
|
mode is generated with s390_isel_amode() instead of
|
|
s390_isel_amode_short(). This is fixed.
