Hongbin Zheng e1fd20172b Add testcase for r154007, when a function has the optsize attribute, 
the loop should be unrolled according the value of OptSizeUnrollThreshold.

Rafael Espindola ba0a6cabb8 Always compute all the bits in ComputeMaskedBits. 
This allows us to keep passing reduced masks to SimplifyDemandedBits, but
know about all the bits if SimplifyDemandedBits fails. This allows instcombine
to simplify cases like the one in the included testcase.

Hongbin Zheng b21b865fe8 LoopUnrollPass: Use variable "Threshold" instead of "CurrentThreshold" when 
reducing unroll count, otherwise the reduced unroll count is not taking
  the "OptimizeForSize" attribute into account.

Bob Wilson 3e66d73259 Fix the install location for the Embedded makefile target. 
svn r145378 inadvertently changed the destination for the Embedded target
in the makefile.  Add a "/Developer" suffix to DSTROOT to compensate.

Pete Cooper 9511ec86f9 Add VSELECT to LegalizeVectorTypes::ScalariseVectorResult. Previously it would crash if it encountered a 1 element VSELECT. Solution is slightly more complicated than just creating a SELET as we have to mask or sign extend the vector condition if it had different boolean contents from the scalar condition.

Bob Wilson 8bbd98df00 When building llvmCore, pass the SDKROOT and -arch setting to configure. 
So far all of configure tests have been run against the default SDK and
architecture, regardless of what is actually being built.  We've gotten
lucky until now.  <rdar://problem/11112479>

Chad Rosier 2a02fe1bb2 Fix an issue in SimplifySetCC() specific to vector comparisons. 
When folding X == X we need to check getBooleanContents() to determine if the
result is a vector of ones or a vector of negative ones. 

I tried creating a test case, but the problem seems to only be exposed on a
much older version of clang (around r144500).

might have more than 19 operands. Add a testcase to make sure I
never screw that up again.

Lang Hames ffa52d2ae2 Matrix simplification in PBQP may push infinite costs onto register options. 
The colorability heuristic should count these as denied registers.

No test case - this exposed a bug on an out-of-tree target.

Anton Korobeynikov 325e92668b Make PPCCompilationCallbackC function to be static, so there will be no need to issue call via

Akira Hatanaka b1f68f9696 Initial 64 bit direct object support. 
This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

The test case checks for both big and little endian flavors.
