Chris Lattner a69f89c17a fix PR5978 by peeling the loop so that we avoid shifting the 
result int by 8 for the first byte.  While normally harmless,
if the result is smaller than a byte, this shift is invalid.

Eric Christopher 7482ad7272 After further thought revert the patch to make fast-isel avoid 
putting relocations into the constant pool - this isn't needed
for correctness and in the rare occasion it happens would pull
us out of fast isel for the block.

If fast-isel application startup time ever becomes an issue we
can add better support for these addresses instead of bailing.

Chris Lattner dab2cd543f Fix rdar://7517201, a regression introduced by r92849. 
When folding a and(any_ext(load)) both the any_ext and the
load have to have only a single use.

This removes the anyext-uses.ll testcase which started failing
because it is unreduced and unclear what it is testing.

Chris Lattner 64ecc468bd fix a globalopt crash on 'bullet' (handling evaluation of a store 
to an element of a vector in a static ctor) which occurs with an 
unrelated patch I'm testing.  Annoyingly, EvaluateStoreInto basically 
does exactly the same stuff as InsertElement constant folding, but it
now handles vectors, and you can't insertelement into a vector.  It
would be 'really nice' if GEP into a vector were not legal.

Evan Cheng 166a4e6caa Teach dag combine to fold the following transformation more aggressively: 
(OP (trunc x), (trunc y)) -> (trunc (OP x, y))

Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel.

This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places.

Duncan Sands 78376ad7e1 Partially address a README by having functionattrs consider calls to 
memcpy, memset and other intrinsics that only access their arguments
to be readnone if the intrinsic's arguments all point to local memory.
This improves the testcase in the README to readonly, but it could in
theory be made readnone, however this would involve more sophisticated
analysis that looks through the memcpy.

Chris Lattner 98748c0964 Teach instcombine's sext elimination logic to be more aggressive. 
Previously, instcombine would only promote an expression tree to
the larger type if doing so eliminated two casts.  This is because
a need to manually do the sign extend after the promoted expression
tree with two shifts.  Now, we keep track of whether the result of
the computation is going to be properly sign extended already.  If
so, we can unconditionally promote the expression, which allows us
to zap more sext's.

This implements rdar://6598839 (aka gcc pr38751)

An instruction like this:

Jakob Stoklund Olesen 4cb7702c4f Remove livein checks from machine code verifier. 
A phi operand that is implicitly defined in a predecessor becomes an undefined
register after phi elimination. This causes a lot of false positives when the
verifier is checking if live-in registers are live-out from all predecessors.

Removing the verifier checks seems like a better solution than insisting on
IMPLICIT_DEF instructions in predecessor blocks.

Dan Gohman ea6f91ff64 Change SelectCode's argument from SDValue to SDNode *, to make it more

This is also a micro-optimization, as passing a SDNode * around is
simpler than passing a { SDNode *, int } by value or reference.

Evan Cheng 7844a99d60 Perform this folding as a target specific dag combine: 
(or (x << c) | (y >> (64 - c))) ==> (shld64 x, y, c)

The isel patterns may not catch all the cases if general dag combine has reduced width of source operands.

Dan Gohman 0f960aed68 A use by operand 1 or 2 of a SELECT is not a FLAGS use. This 
lets the test-elimination work in more conditional-move cases.

Chris Lattner a751d09c08 Truncate GEP indexes larger than the pointer size down to pointer size 
when doing this transform if the GEP is not inbounds.  No testcase because
it is very difficult to trigger this: instcombine already canonicalizes
GEP indices to pointer size, so it relies specific permutations of the
instcombine worklist.

Thanks to Duncan for pointing this possible problem out.
