similar to: [LLVMdev] write a transformation pass

Hello ! I have a toolchain of two passes. First one, is a transformation pass that should add metadata to some structures (instructions/variables) and the second pass is an analyzing pass which needs to access the added metadata. The problem is with my adding metadata transformation pass. There might be two problems(or both): First, maybe I don't add correctly metadata.

Thank you ! I will now redirect the output .bc when dealing with transformation passes On Wed, Feb 13, 2013 at 10:53 AM, Xi Wang <xi.wang at gmail.com> wrote: > On Wed, Feb 13, 2013 at 4:45 AM, Alexandru Ionut Diaconescu > <alexandruionutdiaconescu at gmail.com> wrote: > > Second, I apply my pass : > > //..../llvm/Release+Asserts/bin/opt -load > >

Hello everyone, Till now I have succesfully running passes using RegisterPass template. I have encountered a segfault in my pass. Assertion `AA && "AA didn't call InitializeAliasAnalysis in its run method!"' failed. Then, I tried to use INITIALIZE_PASS_XXXX or INITIALIZE_AG_PASS template, together with `*llvm::createMyMemDepPrinter()` and

Hello everyone, I have written several complex passes till now, but I cannot write a MachineFunctionPass pass. It just gives me segfault. Hence I reduced the pass to the following form : using namespace llvm; namespace { class CFGexplorator : public MachineFunctionPass { public: static char ID; // Pass identification, replacement for typeid CFGexplorator() : MachineFunctionPass(ID)

I found that : "Code generator passes are registered and initialized specially by TargetMachine::addPassesToEmitFile and similar routines, so they cannot generally be run from the *opt* or *bugpoint* commands."...So how I can run a MachineFunctionPass? In the end, I just want to apply a DFS on a CFG of a function. And I need oriented edges and wanted to use

Hi, "we can, once we know how to do it, 'drive' R from within FORTRAN" I am not sure I understand what you mean by this ... You can call routines written in Fortran or C from within R - how easy this is depends on the interfaces to those routines. You can call (some) R functionality from C (see for example

Hi all, While working on a loadable Alias Analysis module pass, I'm running into the following issue: I'm finding my pass queried for results after it has had 'releaseMemory' called on it and its dependencies, but before runOnModule is called again (on my pass or its deps). As you might expect, this makes my pass rather unhappy (and I think correctly so). This happens with LICM

Hi Martyn, Many thanks for your answer. If I make it short : we can, once we know how to do it, 'drive' R from within FORTRAN for example to do a Myarray = seq(0, mydimension) in R once we have compute mydimension in FORTRAN. Is that correct ? If yes : it's too 'complicated' for the time I am hired (I mean I have been hired to do FORTRAN code not to learn R !). Second

I have a patch for this kind of thing attached. Please take a look and let me know if it looks

I was able to process further by making some code changes and replacing export-dynamic with -bexpfull in Makefile.config.

Hi, I am trying to write an LLVM project, using LLVM 2.9. My passes are defined as follows, where the Pass2 requires Pass1. namespace llvm { class BaseClass : public ModulePass { // Name for printing const char* printname; protected: BaseClass(char id, const char* name) : ModulePass(id),printname(name){ } }; class Pass1 : public BaseClass { public: static char ID; Pass1() :

Hi! I am trying to develop an LLVM tool which can apply different optimizations for selected functions. For example, I want to apply an optimization onto one function but not for another one. I am using the standard optimizations available in LLVM. That is the runOnModule function I have written: bool ComplNewBBFuncs::runOnModule(Module &M) { Function *Main =

Hi, I am going to write a module pass (say, P) that uses function level analysis (say, A). Suppose, I analyze two different functions during the P pass: bool P::runOnModule(Module &M) { ... A &X = getAnalysis<A>(F1); ... A &Y = getAnalysis<A>(F2); ... } Will X and Y reference the same object here? It's not a problem for me, as I don't need results of
