2009-07-13Move more functionality over to LLVMContext.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75497 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-13Begin the painful process of tearing apart the rat'ss nest that is ↵Owen Anderson
Constants.cpp and ConstantFold.cpp. This involves temporarily hard wiring some parts to use the global context. This isn't ideal, but it's the only way I could figure out to make this process vaguely incremental. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75445 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Remove the vicmp and vfcmp instructions. Because we never had a release withNick Lewycky
these instructions, no autoupgrade or backwards compatibility support is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74991 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-15Use Type::isIntOrIntVector and Type::isFPOrFPVector.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73433 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-15Support vector casts in more places, fixing a variety of assertionDan Gohman
failures. To support this, add some utility functions to Type to help support vector/scalar-independent code. Change ConstantInt::get and ConstantFP::get to support vector types, and add an overload to ConstantInt::get that uses a static IntegerType type, for convenience. Introduce a new getConstant method for ScalarEvolution, to simplify common use cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73431 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-18Revert r72025. It is possible for clients to convert between signed typesDan Gohman
and pointer types safely if they only do so when the sizes are the same. llvm-gcc is such a client. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72029 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-18Add assertions to CastInst::getCastOpcode to catch attempted conversionsDan Gohman
between integers and pointers when the source type is marked signed, since inttoptr and ptrtoint always use zero-extension when the destination is larger than the source. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72025 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13Second installment of "BasicBlock operands to the back"Gabor Greif
changes. For InvokeInst now all arguments begin at op_begin(). The Callee, Cont and Fail are now faster to get by access relative to op_end(). This patch introduces some temporary uglyness in CallSite. Next I'll bring CallInst up to a similar scheme and then the uglyness will magically vanish. This patch also exposes all the reliance of the libraries on InvokeInst's operand ordering. I am thinking of taking care of that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66920 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12Rearrange operands of the BranchInst, to be able toGabor Greif
access each with a fixed negative index from op_end(). This has two important implications: - getUser() will work faster, because there are less iterations for the waymarking algorithm to perform. This is important when running various analyses that want to determine callers of basic blocks. - getSuccessor() now runs faster, because the indirection via OperandList is not necessary: Uses corresponding to the successors are at fixed offset to "this". The price we pay is the slightly more complicated logic in the operator User::delete, as it has to pick up the information whether it has to free the memory of an original unconditional BranchInst or a BranchInst that was originally conditional, but has been shortened to unconditional. I was not able to come up with a nicer solution to this problem. (And rest assured, I tried *a lot*). Similar reorderings will follow for InvokeInst and CallInst. After that some optimizations to pred_iterator and CallSite will fall out naturally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66815 91177308-0d34-0410-b5e6-96231b3b80d8

s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes.

2008-07-23Enable first-class aggregates support.Dan Gohman
Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8
