2009-06-09Remove an unused function SafeToDestroyConstant(). Rename an almostJay Foad
identical function ConstantIsDead() to SafeToDestroyConstant(), to emphasise the connection with Constant::destroyConstant(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73149 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-09Add the beginnings of an implementatation of lazy liveness analysis, based ↵Owen Anderson
on "Fast Liveness Checking for SSA-form Programs" by Boissinot, et al. This is still very early, hasn't been tested, and is not yet well documented. More to come soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73141 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Use expandCodeFor instead of expand when the result will beDan Gohman
immediately casted. At present, this is just a minor code simplification. In the future, the expansion code may be able to make better choices if it knows what the desired result type will be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73137 91177308-0d34-0410-b5e6-96231b3b80d8

entierly by estimating its side effects on globals, those globals(autos) without a function were not being printed by the Asm printer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73135 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73017 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Create FunctionType::isValidArgumentType to go along with isValidReturnType.Nick Lewycky
Also create isValidElementType for ArrayType, PointerType, StructType and VectorType. Make LLParser use them. This closes up some holes like an assertion failure on: %x = type {label} but largely doesn't change any semantics. The only thing we accept now which we didn't before is vectors of opaque type such as "<4 x opaque>". The opaque can be resolved to an int or float when linking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73016 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Slightly generalize the code that handles shuffles of consecutive loads Eli Friedman
on x86 to handle more cases. Fix a bug in said code that would cause it to read past the end of an object. Rewrite the code in SelectionDAGLegalize::ExpandBUILD_VECTOR to be a bit more general. Remove PerformBuildVectorCombine, which is no longer necessary with these changes. In addition to simplifying the code, with this change, we can now catch a few more cases of consecutive loads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73012 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-06Get rid of some bogus patterns for X86vzmovl. Don't create VZEXT_MOVL Eli Friedman
nodes for vectors with an i16 element type. Add an optimization for building a vector which is all zeros/undef except for the bottom element, where the bottom element is an i8 or i16. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72988 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-05Adapt the x86 build_vector dagcombine to the current state of the legalizer.Nate Begeman
build vectors with i64 elements will only appear on 32b x86 before legalize. Since vector widening occurs during legalize, and produces i64 build_vector elements, the dag combiner is never run on these before legalize splits them into 32b elements. Teach the build_vector dag combine in x86 back end to recognize consecutive loads producing the low part of the vector. Convert the two uses of TLI's consecutive load recognizer to pass LoadSDNodes since that was required implicitly. Add a testcase for the transform.
