55c9ecba47 reimplement truncate() to make it optimal.
It is optimal at least up to 7 bits (I've tested all such cases)
This change to truncate() allows a little simplification to the multiplication code,
and it also makes multiplication optimal :)

d4d961615c This patch fixes 8 out of 20 unexpected failures in "make check"
when run on an Intel Atom processor. The failures have arisen due
to changes elsewhere in the trunk over the past 8 weeks or so.

These failures were not detected by the Atom buildbot because the
CPU on the Atom buildbot was not being detected as an Atom CPU.
The fix for this problem is in Host.cpp and X86Subtarget.cpp, but
shall remain commented out until the current set of Atom test failures
are fixed.

32d75bec4b Fix a somewhat nasty crasher in PR13378. This crashes inside of
LiveIntervals due to the two-addr pass generating bogus MI code.

The crux of the issue was a loop nesting problem. The intent of the code
which attempts to transform instructions before converting them to
two-addr form is to defer and reprocess any transformed instructions as
the second processing is likely to have more opportunities to coalesce
copies, etc. Unfortunately, there was one section of processing that was
not deferred -- the INSERT_SUBREG rewriting. Due to quirks of how this
rewriting proceeded, not only did it occur early, it removed the bits of
information needed for the deferred processing to correctly generate the
necessary two address form (specifically inserting a copy), but didn't
trigger any immediate assertions and produced what appeared to be
already valid two-address from code. Thus, the assertion only fired much
later in the pipeline.

The fix is to hoist the transformation logic up layer to where it can
more firmly defer all further processing, and to teach the normal
processing to handle an edge case previously handled as part of the
transformation logic. This edge case (already matched tied register
operands) needs to *not* defer any steps.

As has been brought up repeatedly in the process: wow does this code
need refactoring. I *may* squeeze in some time to at least bring sanity
to this loop... but wow... =]

Thanks to Jakob for helpful hints on the way here, and the review.

fd34c110cf The vbroadcast family of instructions has 'fallback patterns' in case where the
load source operand is used by multiple nodes. The v2i64 broadcast was emulated
by shuffling the two lower i32 elements to the upper two.
We had a bug in the immediate used for the broadcast.
Replacing 0 to 0x44.
0x44 means [01|00|01|00] which corresponds to the correct lane.

a0f14afee1 Mips specific inline asm operand modifier 'M':
Print the high order register of a double word register operand.

In 32 bit mode, a 64 bit double word integer will be represented
by 2 32 bit registers. This modifier causes the high order register
to be used in the asm expression. It is useful if you are using 
doubles in assembler and continue to control register to variable
relationships.

This patch also fixes a related bug in a previous patch:

    case 'D': // Second part of a double word register operand
    case 'L': // Low order register of a double word register operand
    case 'M': // High order register of a double word register operand

I got 'D' and 'M' confused. The second part of a double word operand
will only match 'M' for one of the endianesses. I had 'L' and 'D'
be the opposite twins when 'L' and 'M' are.

4781d8ee1c indvars: Linear function test replace should avoid reusing undef.
Fixes PR13371: indvars pass incorrectly substitutes 'undef' values.

I do not like this fix. It's needed until/unless the meaning of undef
changes. It attempts to be complete according to the IR spec, but I
don't have much confidence in the implementation given the difficulty
testing undefined behavior. Worse, this invalidates some of my
hard-fought work on indvars and LSR to optimize pointer induction
variables. It results benchmark regressions, which I'll track
internally. On x86_64 no LTO I see:

-3% huffbench
-3% 400.perlbench
-8% fhourstones

My only suggestion for recovering is to change the meaning of
undef. If we could trust an arbitrary instruction to produce a some
real value that can be manipulated (e.g. incremented) according to
non-undef rules, then this case could be easily handled with SCEV.

7c82e6a32a More replacing of target-dependent intrinsics with target-indepdent
intrinsics.  The second instruction(s) to be handled are the vector versions 
of count set bits (ctpop).

The changes here are to clang so that it generates a target independent 
vector ctpop when it sees an ARM dependent vector bits set count.  The changes 
in llvm are to match the target independent vector ctpop and in 
VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM 
dependent vector pop counts with target-independent ctpops.  There are also 
changes to an existing test case in llvm for ARM vector count instructions and 
to a test for the bitcode upgrade.

<rdar://problem/11892519>

There is deliberately no test for the change to clang, as so far as I know, no
consensus has been reached regarding how to test neon instructions in clang;
q.v. <rdar://problem/8762292>
