f3caa525cc X86 address mode matching code MatchAddressRecursively does some aggressive hack which require doing a RAUW. It may end up deleting some SDNode up stream. It should avoid referencing deleted nodes.

There is a better way coming up.

0427b2ac45 Change coalescer complexity from N^2 to N logN by changing one letter.
Remove ugly hack that aborted the coalescer before using N^2 time.

This affects functions with very complicated live intervals for physical
registers, i.e. functions with thousands of function calls.

b675e255d0 Fixed a bug in the IT mask printing where T means the cond bit in the mask
matches that of Firstcond[0] and E means otherwise.  The Firstcond[0] is also
tagged in the Mask to facilitate Asm printing.  The disassembler also depends
on this arrangement.  This is similar to what's described in A2.5.2 ITSTATE.

Ran:

utils/lit/lit.py test/CodeGen/ARM test/CodeGen/Thumb test/CodeGen/Thumb2

successfully.

77bdc48eb6 Refines 98745 so that it only contains the patch related to the output of the
addressing modes to omit the '+' from the assembler syntax #+/-<imm> or +/-<Rm>.

This patch removes the impl of printT2AddrModeImm8s4OffsetOperand() from
ARMAsmPrinter.cpp.  It is used by disassembler as of now.

0afc29c3e6 Change SCEVNAryExpr's operand array from a SmallVector to a plain
pointer and length, and allocate the arrays in ScalarEvolution's
BumpPtrAllocator, so that they get released when their owning
SCEV gets released. SCEVs are immutable, so they don't need to worry
about operand array resizing. This fixes a memory leak reported
in PR6637.

9e08876a2a 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]

5b33f3148c Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*.

b7ccf75de5 Fix a false-positive memory leak in code using RemoveFileOnSignal(). Because
libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

2b0272e43d Disambiguate the *_UPD and * variants by specifying the writeback flag as 1.

In such case, we'll use an adhoc approach to deduce the Opcode programmatically.
