7cea0e9dd5 98745 contains something unrelated to the patch.
Remove it from ARMAddressingModes.h.

0212e0df47 Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
instructions to help disassembly.

We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

And modified test cases to not expect '+' in +reg or #+num.  For example,

; CHECK:       ldr.w	r9, [r7, #28]

79f10e6233 Remove redundant writeback flag from ARM address mode 6. Also remove the
optional register update argument, which is currently unused -- when we add
support for that, it can just be a separate operand.

54bb1efbe0 Disambiguate the *_UPD and * variants by specifying the writeback flag as 1.
This is for the disassembly work.

There are cases where this is not possible, for example, A8.6.53 LDM Encoding T1.
In such case, we'll use an adhoc approach to deduce the Opcode programmatically.

ff030064fb Initial ARM/Thumb disassembler check-in. It consists of a tablgen backend
(RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb,
and the disassembler core which invokes the decoder function and builds up the
MCInst based on the decoded Opcode.

Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
instructions to help disassembly.

We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

67c88e4977 Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.
This does not move entirely to UAL syntax, since the default "increment after"
suffix is empty but we still use "IA" for that.

241d3cb048 MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

b8ec72ddcb Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing
to is local to the translation unit, we need to place fill the value of that
symbol into the non-lazy pointer.

This should conclude all Darwin changes for placing the LSDA into the TEXT
section. There is some cleanup to do. I.e., there's no longer a special need for
target-specific code here. But that can come later.

149cf816bb change EH related stuff (other than EH_LABEL) to use MCSymbol
instead of label ID's.  This cleans up and regularizes a bunch 
of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places.  This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction.  There should not be any 
functionality change from doing this, but I'm not an EH expert.
