2009-06-09Reversed order of args in EXPECT_EQ() macros to be in the correct order:Misha Brukman
EXPECT_EQ(expected, actual) . This will make error messages understandable as it uses terms such as "expected" and "actual" based on the order of arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73150 91177308-0d34-0410-b5e6-96231b3b80d8
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

2009-06-09I'm going to assume that this was meant to be an assignment instead of aBill Wendling

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
2009-06-09Change IndexedModeAction representation.David Greene
This changes the IndexedModeAction representation to remove the limitation on the number of value types in MVT. This limitation prevents us from specifying AVX types. Prior to this change IndexedModActions was represented as follows... uint64_t IndexedModeActions[2][ISD::LAST_INDEXED_MODE]; the first dimension was used to represent loads, then stores. This imposed a limitation of 32 on the number of value types that could be handled with this method. The value type was used to shift the two bits into and out of the approprate bits in the uint64_t. With this change the array is now represented as ... uint8_t IndexedModeActions[MVT::LAST_VALUETYPE][2][ISD::LAST_INDEXED_MODE]; Takes more space but removes the limitation on MVT::LAST_VALUETYPE. The first dimension is now the value_type for the reference. The second dimension is the load [0] vs. store[1]. The third dimension represents the various modes for load store. Accesses are now direct, no shifting or masking. There are other limitations that need to be removed, so that MVT::LAST_VALUETYPE can be greater than 32. This is merely the first step towards that goal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73104 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
