similar to: Printing out a 128 bit decimal

Hi, I was trying to print out a 128 bit result at runtime using a call to printf in LLVM. I am able to print 32 uptil 64 bit integers using the format string "%d" in printf . Please see the code in red below , as I am having a bit difficulty in trying to print the 128 bit value computed at runtime. The code in red is never executed since the value may never be casted to a

Hi, Just had a simple question , The use-def and def-use chains provided by llvm::Value class , would they work for IR that has not been optimized by the "mem2reg" pass ? ( ie, IR code that contains memory interactions and is not in SSA form yet ) Thanks, Malhar -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I have been trying to move some instructions between basic blocks , After looking at the API , I found llvm::Instruction::clone() but there is no result value for this. For example- source Basic block : continuation: ; preds = %else, %then %iftmp = phi i32 [ 5, %then ], [ 9, %else ] store i32 %iftmp, i32* %datasize ; 3 instructions below

Hi, I was wondering if it was possible to create a Dummy Type by subclassing LLVM Type. I do not want to create a new type or even do much with this dummy type , all I need is a placeholder type until I generate IR. I want to use this approach as most of my AST is already configured to accept a Type* and not a DummyType* ( which is my own class ) I explored this a bit and did manage to

I was trying to run the simplify CFG Pass in LLVM , and delete an unreachable basic block ("continuation" below ) after running one of my own IR transforms , but I keep getting the error - While deleting: i8* %g Use still stuck around after Def is destroyed: store i8 0, i8* %g I am well aware of what that means, but isn't the whole purpose of the "simplifyCFGPass" to

Hi everyone, I just had a question - I am aware that LLVM supports it's own form of RTTI ( using dyn_cast<>() ,etc) but I wish to use C++ RTTI currently. I have tried building with "cmake -G "Unix Makefiles" -LLVM_ENABLE_RTTI=ON" but that doesnt seem to remove the "fno-rtti" flag from llvm-config and I still get an error when I try using

Dear all, I just created this revision <https://reviews.llvm.org/D34937> but I did not receive any email for it even though it says 'Automatically Subscribed' on the right. Also, even my profile shows no trace of the aforementioned revision. It shows that my last activity was on 24th May. Additionally, just to verify that I am not receiving any emails from Phabricator, I logged

Hey all, I have a piece of code (written in LLVM 2.8) which uses profiling results produced by ProfileInfo. It essentially computes the number of iterations performed by a loop from the profiling information available. The code snippet in my pass looks something like this. BasicBlock *header = loop->getHeader(); ProfileInfo &pi = getAnalysis< ProfileInfo >(); for(pred_iterator

Hello everyone, In the file *lib/CodeGen/AsmPrinter/AsmPrinter.cpp*, I would like to obtain an MCInst corresponding to its MachineInstr. Can anyone tell me a way to do that? If that is not possible, then, I would like to know if a given MachineInstr is an *lea *instruction and I would like to know if the symbol involved with this lea instruction is a jump-table. For instance, given a

Hello. I come back to this older thread. Again, because of i64immSExt32 I receive TableGen error "Could not infer all types in, pattern!" (exact details written below). So far I'm not able to generate selection code with TableGen for the ADD_r* instructions, etc: def i64immSExt32 : PatLeaf<(imm), [{return

Hello, What is the easiest way which enables usage of decimal comma "," instead of decimal point (".") . I would like to force all RoR views to display float numbers with comma instead of decimal point and also to allow insertion of float numbers with comma in forms.

I've been debugging some strange happenings over here and I put an assert in APInt to catch what I think is the source of the problem: int64_t getSExtValue() const { // An i1 -1 is unrepresentable. assert(BitWidth != 1 && "Signed i1 value is not representable!"); To me an i1 -1 makes no sense whatsoever. It is not representable in twos-complement form. It cannot
