So is there a way to return the value as a string instead?

Hi all, I'm fiddling around a bit with programmatically created GEP instructions, which is failing when using i64 for any indix, except the first. The reason behind this, is that StructureType::indexValid only accepts Value* that are constant ints of width 32. I can't really see why this limitation is here. SequentialType solves this slightly differently, it allows for both 32 and 64

...type is i32. I think "indexValue" must hold a number which type is int. Now I want to use the exact number which pointed by indexValue , so I do like this: ConstantInt* CI = llvm::cast<llvm::ConstantInt>(indexValue); //This is wrong, so is dyn_cast. uint64_t index = indexValue->getZExtValue(); uint64_t size = index + 1; I don't know if it is the right way. So, could anybody tell the way to get the integer content from a Value* which type is i32? I'll be very very grateful if there is any answer. -------------- next part -------------- An HTML attachment was scrubbed... URL:...

It seems that Tablegen is generating intrinsic ID's off by in DAGISel.inc In DAGISel.inc, I have the following pattern: int64_t CN1 = Tmp0->getZExtValue(); // Pattern: (intrinsic_w_chain:f32 103:iPTR, GPRF32:f32:$src0, GPRF32:f32:$src1, GPRF32:f32:$src2) // Emits: (MACRO_FMA_f32:f32 GPRF32:f32:$src0, GPRF32:f32:$src1, GPRF32:f32:$src2) // Pattern complexity = 8 cost = 1 size = 0 if (CN1 == INT64_C(103)) { SDValue N2...

Hi, I'm reading the code in CBackend.cpp and found some wired chunk in void CWriter::printConstant(Constant *CPV) 938 if (ConstantInt *CI = dyn_cast<ConstantInt>(CPV)) { 939 const Type* Ty = CI->getType(); 940 if (Ty == Type::Int1Ty) 941 Out << (CI->getZExtValue() ?

Also, IndVarSimplify.cpp has the same problem, only one abs usage in it, line 700: if (Max.getZExtValue() > static_cast<uint64_t>(abs(intEV - intIV))) Following your style change: if (Max.getZExtValue() > static_cast<uint64_t>(abs64(intEV - intIV))) Also, why make an abs64, why not just override abs with 64 bit parameters?

Are you using isTarget = 1 in your intrinsics file?

I am working on an experimental target and trying to make sure that the load offset field is used to the best way. There appears to be some control over the architecture's offset range and whether the offset is too large and needs to be lowered/converted into a separate sequence of operations in DAGSelection? Can someone point me to what might be the case? For example, the difference between

if (ConstantInt *c = (ConstantInt *) dyn_cast<ConstantInt>(index)){ errs() << "And it's a constant!!!!!!1111oneone!! (" <<c->getZExtValue() << ")\n"; } -- "Believe you can, believe you can't; either way you're right."  -Henry Ford -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of help__me_please Sent: Thursday, April 22, 2010 8:38...

...t SDNodes into other values. For a worked example, in the MIPS backend we use this for constant synthesis by materializing the value into a register: (From lib/Target/MipsInstrInfo.td): // Transformation Function - get the lower 16 bits. def LO16 : SDNodeXForm<imm, [{ return getImm(N, N->getZExtValue() & 0xFFFF); }]>; The above fragment will take an immediate node and get the lower 16 bits. // Transformation Function - get the higher 16 bits. def HI16 : SDNodeXForm<imm, [{ return getImm(N, (N->getZExtValue() >> 16) & 0xFFFF); }]>; Similarly, get the high 16 bits....

...on is that the compiler interpret the pretty vague team "object" in different ways -- the "object" suggested by line 359 @ figure 1 is just a part of the "object" implied by Figure 2. I try to fix the problem PR14988 by replacing line 359 with "Size = Offset.getZextValue()"; It does fix the problem. However, I'm wondering in what situations the Offset != 0. So I put an assertion right before line 359, saying "assert(Offset != 0)". It catches two cases in SingleSource test suite. I investigate one of them, the assertion is triggered when the llv...

Hi all, I have the condition of an ICmpInst in a variable called condition obtained doing GenericValue condition = getOperandValue(&I, SF); Now I would like to understand if the comparison was true or false. Is it correct to use condition.IntVal.getSExtValue() and if the value is 0 consider the true and if the value is -1 consider the condition false? I'm not sure because I was expecting
