From FEDORA_PATCHES Mon Sep 17 00:00:00 2001

Subject: gdb-rhel-86801-binutils-z17-update-3of12.patch
;; Backkport "s390: Add missing extended mnemonics"
;; (Jens Remus, RHEL-86801)
Add extended mnemonics specified in the z/Architecture Principles of
Operation [1] and z/Architecture Reference Summary [2], that were
previously missing from the opcode table.
The following added extended mnemonics are synonyms to a base mnemonic
and therefore disassemble into their base mnemonic:
jc, jcth, lfi, llgfi, llghi
The following added extended mnemonics are more specific than their base
mnemonic and therefore disassemble into the added extended mnemonic:
risbhgz, risblgz, rnsbgt, rosbgt, rxsbgt
The following added extended mnemonics are more specific than their base
mnemonic, but disassemble into their base mnemonic due to design
constraints:
notr, notgr
The missing extended mnemonic jl* conditional jump long flavors cannot
be added, as they would clash with the existing non-standard extended
mnemonic j* conditional jump flavors jle and jlh. The missing extended
mnemonic jlc jump long conditional is not added, as the related jl*
flavors cannot be added.
Note that these missing jl* conditional jump long flavors are already
defined as non-standard jg* flavors instead. While the related missing
extended mnemonic jlc could be added as non-standard jgc instead it is
forgone in favor of not adding further non-standard mnemonics.
The missing extended mnemonics sllhh, sllhl, slllh, srlhh, srlhl, and
srllh cannot be implemented using the current design, as they require
computed operands. For that reason the following missing extended
mnemonics are not added as well, as they fall into the same category of
instructions that operate on high and low words of registers. They
should better be added together, not to confuse the user, which of those
instructions are currently implemented or not.
lhhr, lhlr, llhfr, llchhr, llchlr, llclhr, llhhhr, llhhlr, llhlhr,
nhhr, nhlr, nlhr, ohhr, ohlr, olhr, xhhr, xhlr, xlhr
