Hi, In llvm 3.0 llvm::ConstantArray had a ::getAsCString() method that returned the buffer as a std::string. Now it seems that 3.1 this method dissapeared. I found that llvm::ConstantDataArray has a method called getAsString(), but it returns a Constant*. What is the safe way to retrieve the pointer of the Constant array as a C string?

i'm afraid this question is extremely basic, but i've assumed that dumping a .bc file from a module was a trivial operation, but now, first time i have to actually do it from code, for the life of me i can't find one missing step in the process: static void WriteModule ( const Module * M, BitstreamWriter & Stream )

Hi, I have two functions in a module, X.foo, which is the callee, and Y.foo2, which calls X.foo. If i either try to run llvm::Function::eraseFromParent() on any one of the functions, i'll get this assertion error: F is used in instruction: %"calling function" = call i32 @X.foo(i32 %read) F is used in instruction: %"calling function" = call i32 @X.foo(i32 %read) While

Would that work

Hi, JIT does not allow functions to call others in different modules, so all modules need to be statically linked in a big fat module. If a module needs to be recompiled, all the others need to as well as relinked. there are two ways i intend to approach this problem: 1) forget about JITing, build each module into a .bc, call gcc to generate .soname libraries, dynamically load with dlopen()

Hi, in ExceptionDemo code ( https://llvm.org/viewvc/llvm-project/llvm/trunk/examples/ExceptionDemo/ExceptionDemo.cpp?view=markup&sortby=file ) the function "ourPersonality" is defined. a llvm::Function is created with the same name inside function "createStandardUtilityFunctions". The llvm::Function is retrieved in function "createCatchWrappedInvokeFunction".

suppose module B has call/InvokeInst to calls in module A after i clone both modules i get B' and A' my concrete question is this: Are there any special steps that i need to do before linking the modules B' and A' together? my main concern is that B' will have call/InvokeInst pointing to module A, not A', and the linker will not be able to notice that it should replace

Hi, I have this module: ; ModuleID = './executableModule' @typeInfo0 = constant { i32 } zeroinitializer @typeInfo1 = constant { i32 } { i32 1 } @typeInfo2 = constant { i32 } { i32 2 } @typeInfo3 = constant { i32 } { i32 3 } @typeInfo4 = constant { i32 } { i32 4 } @typeInfo5 = constant { i32 } { i32 5 } @typeInfo6 = constant { i32 } { i32 6 } declare void @print32Int(i32, i8*) declare

Hi, I'm having an issue with the below modules. I build module X, then module Y (which has a dependency on X). I've added an external declaration on module Y of the functions defined in X. i also link the except-handling module, but i think it is peripheral to the issue i like all the modules together in a single module called executableModule. I link them with the method:
