This DAG combine BRCOND transformation can look pass truncate of the operand:
...
// %a = ...
// %b = and i32 %a, 2
// %c = srl i32 %b, 1
// brcond i32 %c ...
//
// into
//
// %a = ...
// %b = and i32 %a, 2
// %c = setcc eq %b, 0

Make sure it restores local variable N1, which corresponds to the condition operand if it fails to match.
This apparently breaks TCE but since that backend isn't in the tree I don't have a test for it.

Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel!
...
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
named. Since it is just a predicate and isn't actually changing any state.
2) Added a missing return in the comments for setCurrentDwarfLoc() in
include/llvm/MC/MCContext.h for fix formatting.
3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
state.
4) Simplified the last test in isValidDwarfFileNumber() to just a one line
boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

This adds a Darwin x86_64 relocation encoding for a subtraction expression
...
where both symbols are "local", that is non-external symbols, and there is
no "base" for the symbols used in the expression, that is the section has
no non-temporary symbols. This case looks like this:
% cat local_reloc_A-B.s
.long 0
LB: .long 1
.long LA - LB - 4
.long 2
LA: .long 3
which llvm-mc will not encode without this patch, generates a "unsupported
local relocations in difference" error, but the Darwin assembler will
encode with relocation entries like this:
% otool -rv a.out l.out
a.out:
Relocation information (__TEXT,__text) 2 entries
address pcrel length extern type scattered symbolnum/value
00000008 False long False SUB False 1 (__TEXT,__text)
00000008 False long False UNSIGND False 1 (__TEXT,__text)
which is very similar to what is encoded when the symbols don't have the
leading 'L' and they are not temporary symbols. Which llvm-mc and the
Darwin assembler will encoded like this:
Relocation information (__TEXT,__text) 2 entries
address pcrel length extern type scattered symbolnum/value
00000008 False long True SUB False B
00000008 False long True UNSIGND False A
This is the missing relocation encoding needed to allow the Mach-O x86
Dwarf file and line table to be emitted. So this patch also removes the
TODO from the if() statement in MCMachOStreamer::Finish() that didn't
call MCDwarfFileTable::Emit() for 64-bit targets.

This fixed PR8249 where a valno with a multi-segment live range was defined by
an identity copy created by RemoveCopyByCommutingDef. Some of the live

Massive rewrite of MMX:
...
The x86_mmx type is used for MMX intrinsics, parameters and
return values where these use MMX registers, and is also
supported in load, store, and bitcast.
Only the above operations generate MMX instructions, and optimizations
do not operate on or produce MMX intrinsics.
MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
smaller pieces. Optimizations may occur on these forms and the
result casted back to x86_mmx, provided the result feeds into a
previous existing x86_mmx operation.
The point of all this is prevent optimizations from introducing
MMX operations, which is unsafe due to the EMMS problem.

When isel is emitting instructions for an x86 target without CMOV, the CFG is
...
edited during emission.
If the basic block ends in a switch that gets lowered to a jump table, any
phis at the default edge were getting updated wrong. The jump table data
structure keeps a pointer to the header blocks that wasn't getting updated
after the MBB is split.
This bug was exposed on 32-bit Linux when disabling critical edge splitting in
codegen prepare.
The fix is to uipdate stale MBB pointers whenever a block is split during
emission.

This is the last major patch to implement support for the .loc directive
...
and output the dwarf line number tables. This contains the code to emit and
encode the dwarf line tables from the previously gathered information in the
MCLineSection objects. This contains all the details to encode the line and
address deltas into the dwarf line table.
To do this an MCDwarfLineAddrFragment has been added.
Also this moves the interface code out of Mach-O streamer into
MCDwarf so it should be useable by other object file formats.
There is now one call to be made from an MCObjectStreamer
EmitInstruction() method:
MCLineEntry::Make(this, getCurrentSection());
to create a line entry after each instruction is assembled.
And one call call to be made from an MCObjectStreamer Finish() method:
MCDwarfFileTable::Emit(this, DwarfLineSection);
when getContext().hasDwarfFiles() is true and is passed a object file specific
MCSection where to emit the dwarf file and the line tables.
This appears to now be correct for 32-bit targets, at least x86. But the
relocation entries for 64-bit Darwin needs some further work which is next
up to work on. So for now the 64-bit Mach-O target does not output the
dwarf file and line tables.

delete the MDNode that changed, rather than the other MDNode.
This is less work, because it doesn't require the changed node
to be re-inserted into the uniquing map and it doesn't require
the is-function-local flag to be recomputed. Also, it avoids
trouble when the existing node is part of a complicated
data structure.

My previous fix for rdar://8456371 should only apply to fmulp/faddp,
not to fmul/fadd. Instruction set orthogonality is overrated or
something.

LoadPRE was not properly checking that the load it was PRE'ing post-dominated the block it was being hoisted to.
...
Splitting critical edges at the merge point only addressed part of the issue; it is also possible for non-post-domination
to occur when the path from the load to the merge has branches in it. Unfortunately, full anticipation analysis is
time-consuming, so for now approximate it. This is strictly more conservative than real anticipation, so we will miss
some cases that real PRE would allow, but we also no longer insert loads into paths where they didn't exist before. :-)
This is a very slight net positive on SPEC for me (0.5% on average). Most of the benchmarks are largely unaffected, but
when it pays off it pays off decently: 181.mcf improves by 4.5% on my machine.
