Add a testcase based on sret.cpp where we can now hash the entire
compile unit.

llvm-svn: 203319

This is already done for shifts.  Allow it for rotations as well. E.g.:

   (rotl:i32 x, (trunc (and y, 31))) -> (rotl:i32 x, (and (trunc y), 31))

Use the newly factored-out distributeTruncateThroughAnd.

With this patch and some X86.td tweaks we should be able to remove redundant
masking of the rotation amount like in the example above.  HW implicitly
performs this masking.

The testcase will be added as part of the X86 patch.

llvm-svn: 203316

This is the new idiom:

  x<<(y&31) | x>>((0-y)&31)

which is recognized as:

  x ROTL (y&31)

The change refines matchRotateSub.  In
Neg & (OpSize - 1) == (OpSize - Pos) & (OpSize - 1), if Pos is
Pos' & (OpSize - 1) we can just use Pos' instead of Pos.

llvm-svn: 203315

Slightly change the wording in the function comment. Originally, it can be
misunderstood as we turned the input into two subsequent rotates.

Better connect the comment which talks about Mask and the code which used
LoBits.  Renamed variable to MaskLoBits.

be split and the result type widened.

When the condition of a vselect has to be split it makes no sense widening the
vselect and thereby widening the condition. We end up in an endless loop of
widening (vselect result type) and splitting (condition mask type) doing this.
Instead, split both the condition and the vselect and widen the result.

I ran this over the test suite with i686 and mattr=+sse and saw no regressions.

Fixes PR18036.

First: refactor out the emission of entries into the .debug_loc section
into its own routine.

Second: add a new class ByteStreamer that can be used to either emit
using an AsmPrinter or hash using DIEHash the series of bytes that
would be emitted. Use this in all of the location emission routines
for the .debug_loc section.

No functional change intended outside of a few additional comments
in verbose assembly.

Previously, the assertions in PointerIntPair would try to calculate the value
(1 << NumLowBitsAvailable); the inferred type here is 'int', so if there were
more than 31 bits available we'd get a shift overflow.

Also, add a rudimentary unit test file for PointerIntPair.

The integrated assembler now works for ppc. Since this was the last use of the
bg/p predicate and Hal says that it is now dead, drop the predicate too.

This is a straightfoward replacement, it makes debugging a little
