similar to: [LLVMdev] Get the value of a GlobalVariable

How can I safely mock a singleton without the mocked method living on outside the scope of the test method? I''ve run into this problem with mocking methods on globals (gasp!) in the past by doing something like def mock_my_global original = $my_global $my_global.expects(:foo).returns(''bar'') yield $my_global = original end Is there something similar I

hi Duncan Sands, i have tried the functions: GlobalValue * getNamedValue (StringRef Name) const GlobalVariable * getGlobalVariable (StringRef Name, bool AllowInternal=false) const GlobalVariable * getNamedGlobal (StringRef Name) const but i think these functions just return the ID or something else (not the Global Variable's main memory address, i am not sure) here is the thing. i

The docs are pretty vague about this. After digging into the examples I got the following to work with JIT to gain a pointer to variable elsewhere in the runtime, but I'd like to understand what is going on here, and if there is a, um, nicer API that I'm missing? llvm::Value* C::getGlobalVariable(const char* name, llvm::Type* t) {

What is the proper solution to disable auto-vectorization for unaligned data? I have an out of tree target and I added this: bool OpusTargetLowering::allowsUnalignedMemoryAccesses(EVT VT, bool *Fast) const { if (VT.isVector()) return false; .... } After that, I could see that vectorization is still done on unaligned data except that llvm will copy the data back and forth from the source

Out of curiosity, I'm replacing the JIT with MCJIT on my compiler. As all "external" functions are provided by the language's FFI mechanism, it does MyExecutionEngine->DisableSymbolSearching(); MyExecutionEngine->InstallLazyFunctionCreator(&MyLazyFunctionCreator); which works fine with the JIT. However, MCJIT insists on resolving unknown symbols by searching them

If auto-vectorization is making a given loop slower on your target, that means the cost metrics are off, and we should fix them. If code size is an issue, you should tell the optimizer

Ok any quick workaround to limit vectorization to 16-byte aligned 128-bit data then? All the memory copying done by ExpandUnalignedStore/ExpandUnalignedLoad is just too expensive.

I am having trouble installing RMySQL on a clean install of Fedora Core 4 64 bit on a dual dual core machine (that is, two dual core processors). Seems like the LD_LIBRARY_PATH is incorrect, but I don't seem to have it quite right yet. There are a few mentions of this problem in google, but thus far none of the "fixes" and fixed my problem. I've tried defining the

Hi all, I have a patch that would potentially help Objective-C 2. In the "make_decl_llvm()" in llvm-backend.cpp, there is code to search through the already generated global variables. Objective-C goes through this code twice with the same identifier. The first time, is to create meta-data for a "property". The second time is to add a reference to that property into the

I'm having some trouble getting access to a global variable with getPointerToGlobal. The resulting value is not what I am expecting. My assembly looks something like this: @gresult = global i32 undef define i32 @eval_expr() { entry: ... store i32 %3, i32* @gresult ret i32 %3 } Where "gresult" is created with: auto global = new llvm::GlobalVariable( *module, int32Type,

Hi all, are there any plans to correct/implement the "getPointerToGlobal()" method for accessing global variables that are emitted by MCJIT? (see for details the unit test of MCJIT) Best Regards Armin

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

Hello! I am coming back to the below discussion again, regarding the LLVM support of Ruby dynamics. The initial problem description is as follow, to refresh your memory :) After that my questions come: -----------BEGIN Initial problem description--------------- Problem is though, that the Ruby compiler is integrated in the compilation of the program being executed, to be able to parse &

Hi all, I need to run c++ prgrams using lli. However, I find lli cannot handle the alias instruction correctly. Following is an example: ------------ example.cc ------------- #include <iostream> using namespace std; class cls { public: cls(); ~cls(); }; cls::cls() { cout << "constructor" << endl; }; cls::~cls() { cout <<

As far as I know, no one is working to fix the test case in question.

Hi Everyone, I'm quite new to LLVM and I want to update value of global variable in LLVM IR. I created new global variable in ModulePass: bool runOnModule(llvm::Module &M) { IRBuilder<> Builder(M.getContext()); Instruction *I = &*inst_begin(M.getFunction("main")); Builder.SetInsertPoint(I); M.getOrInsertGlobal("globalKey",
