9aa8beb9d6 [SystemZ] Add MC support for LEDBRA, LEXBRA and LDXBRA
These instructions aren't used for codegen since the original L*DB instructions
are suitable for fround.

6b6889d87b [SystemZ] Add support for z196 float<->unsigned conversions
These complement the older float<->signed instructions.

185ef05ad6 [SystemZ] Add comparisons of large immediates using high words
There are no corresponding patterns for small immediates because they would
prevent the use of fused compare-and-branch instructions.

7d0b89bedd [SystemZ] Reapply: Add definitions of LFH and STFH
Originally committed as r191661, but reverted because it changed the matching
order of comparisons on some hosts.  That should have been fixed by r191735.

16658af535 [SystemZ] Revert r191661: Add definitions of LFH and STFH
For some reason, adding definitions for these load and store
instructions changed whether some of the build bots matched
comparisons as signed or unsigned.

d954716e75 [SystemZ] Add FI[EDX]BRA
These are extensions of the existing FI[EDX]BR instructions, but use a spare
bit to suppress inexact conditions.

f3068d02e5 [SystemZ] Add RISBLG and RISBHG instruction definitions

cf20e45cc4 [SystemZ] Add LOC and LOCG
As with the stores, these instructions can trap when the condition is false,
so they are only used for things like (cond ? x : *ptr).


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187112 91177308-0d34-0410-b5e6-96231b3b80d8

b284e1bf08 [SystemZ] Add STOC and STOCG
These instructions are allowed to trap even if the condition is false,
so for now they are only used for "*ptr = (cond ? x : *ptr)"-style
constructs.

6dae7ae765 [SystemZ] Add tests for ALHSIK and ALGHSIK
The insn definitions themselves crept into r186689, sorry.
This should be the last of the distinct-ops instructions.

c7c7e1502a [SystemZ] Add ALRK, AGLRK, SLRK and SGLRK
Follows the same lines as r186686, but much more limited, since we only
use ADD LOGICAL for multi-i64 additions.

70d3e71f2e [SystemZ] Add AHIK and AGHIK
I did these as a separate patch because it uses a slightly different
form of RIE layout.

db92fb0716 [SystemZ] Add NRK, ORK and XRK
The atomic tests assume the two-operand forms, so I've restricted them to z10.

Running and-01.ll, or-01.ll and xor-01.ll for z196 as well as z10 shows why
using convertToThreeAddress() is better than exposing the three-operand forms
first and then converting back to two operands where possible (which is what
I'd originally tried).  Using the three-operand form first stops us from
taking advantage of NG, OG and XG for spills.

eddfaad1ef [SystemZ] Start adding z196 and zEC12 support
This first step just adds definitions for SLLK, SRLK and SRAK.
The next patch will actually make use of them during codegen.

insn-bad.s tests that some form of error is reported when using these
instructions on z10.  More work is needed to get the "instruction requires:
distinct-ops" that we'd ideally like, so I've stubbed that part out for now.
I'll come back and make it mandatory once the necessary changes are in.
