similar to: Print 128 bit value at runtime using printf

Hi, I was wondering how I can print out the result of some arithmetic on 128 bit integers. After having a look at the API , it seems it is possible to get the integer value from the "ConstantInt::getSextValue() " but the return value is only a int64_t. I wish to print it on the console output and printing as a string or decimal ( using C standard library printf ) My Question :

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 listers, I just run R CMD check on an update of one of my packages. All seems fine but after having gone through all the Rd-file and example checking and so on, I get the following kind of errors: LaTeX errors when creating PDF version. This typically indicates Rd problems. LaTeX errors found: ! Font T1/ptm/m/n/10=ptmr8t at 10.0pt not loadable: Metric (TFM) file not found . <to be read

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

I have just installed R version 2.14.0 and tried to re-build and re-check some of the packages that I maintain.

But %S is not valid in C99 or POSIX, even if it is a variant in some systems. I am working on a more careful checker right now, but there will be limits to what we can catch: this was already a pretty rare example.

Hi Thomson, the new call to puts() is inserted right away, whereas the old call to printf() is removed a bit later in SimplifyLibCalls::runOnFunction(). If you browse the code a bit and backtrack the call stack to see what happens with the return value of PrintFOpt::OptimizeFixedFormatString(), you will stumble upon this segment in SimplifyLibCalls.cpp:1703ff.: // Try to optimize this call.

Hi All, I am trying to insert printf ("%d", v), where v is an integer param, into the IR. I am doing something wrong because I keep getting segfaults. Below is my code.
