On top of the GDB 11.1/2 release we will need the following Binutils upstream patches:

* e4cc3b47ec2c4bdb1892db7e9759f90576742f31 IBM Z: Add another arch14 instruction
* a164bbda300d1da6f97bfa14ba7fa22475e61d17 IBM Z: Remove lpswey parameter

Since the transition to binutils 2.38 started for jammy, and v2.38 is meanwhile in -proposed:
 binutils | 2.37.90.20220130-0ubuntu2 | jammy
 binutils | 2.38-1ubuntu1 | jammy-proposed

and since the two commits requested above are included in v2.38:
e4cc3b47ec2 "IBM Z: Add another arch14 instruction" --> binutils-2_38
a164bbda300 "IBM Z: Remove lpswey parameter" --> binutils-2_38

I'm updating this ticket to Fix Committed.

Just to make sure we get this right. The GDB build usually does not use the installed binutils packages for its disassembly but rather the binutils version in the same source tree at the time the GDB release was done. We have opened this request to make sure that the GDB you are using uses a binutils source tree with the proper patchlevel. The level of the binutils package probably does not matter here.

I've verified that GDB on jammy disassembles the new instructions correctly. Thanks!
