Subject: [PATCH] Bug 400491 s390x: Sign-extend immediate operand of LOCHI and
|
|
friends
|
|
|
|
The VEX implementation of each of the z/Architecture instructions LOCHI,
|
|
LOCHHI, and LOCGHI treats the immediate 16-bit operand as an unsigned
|
|
integer instead of a signed integer. This is fixed.
