...like the C++ API allows one to do what I'm describing, but I don't see a way to do it with the C bindings. I'd like to add the following functions. Hopefully my intent is clear. I'm very open to name suggestions, as these are a mouthful: void LLVMAppendExistingBasicBlockInContext(LLVMContextRef C, LLVMValueRef Fn, LLVMBasicBlock BB); void LLVMInsertExistingBasicBlockInContext(LLVMContextRef C, LLVMBasicBlockRef InsertBeforeBB, LLVMBasicBlock BB); void LLVMAppendExistingBasicBlock(LLVMValueRef Fn, LLVMBasicBlock BB); void LLVMInsertExistingBasicBlock(LLVMBasicBlockRef InsertBeforeBB, LLVMB...

I'm trying to use LLVMGetBitcodeModuleInContext2 to load a .bc file. However, it's not working. The code looks something like this: void llvm_load_IR_library(char *path) { LLVMContextRef global_context; LLVMMemoryBufferRef module_path; LLVMModuleRef ir_lib_module; bool flag; module_path = LLVMCreateMemoryBufferWithMemoryRange(path, strlen(path), "path", 1); global_context = LLVMGetGlobalContext(); flag = LLVMGetBitcodeMod...

Hi Tim, Thanks for the hint. I tried the following, (it's a C interface since that's what I need it for) where a and b are the top and bottom halves of the 128 bit value, LLVMValueRef TestConst(LLVMContextRef C, uint64_t a, uint64_t b) { Type *ty = Type::getFP128Ty(*unwrap(C)); ArrayRef<uint64_t> ar[2] = {a,b}; APInt ai(128,*ar); APFloat quad(APFloat::IEEEquad(), ai); return wrap(ConstantFP::get(ty,quad)); } but for 1.0e0 it returns zero store fp128 0xL0000000000000000000000000000000...

Hi All I am a novice LLVM user trying to use LLVMConstIntOfString using the c api to get a integer of arbitrary size from a hexadecimal string. Example code follows: LLVMContextRef context = LLVMContextCreate(); LLVMValueRef value = LLVMConstIntOfString(LLVMInt64TypeInContext(context), "0x0000000f0000ffff", 16); This is working properly as expected. However I have noticed that if the bits are not prefixed with enough zeros to correspond to 32 or 64 bits this gi...

Or do you mean I need to load the module into memory before calling LLVMGetBitcodeModuleInContext2? > Yes, you need to load the module into memory first. > LLVMCreateMemoryBufferWithContentsOfFile will do that for you.

...nly take a LLVMContext, such as replacing the global variable Type::FloatTy with a function Type::getFloatTy(LLVMContext&). For llvm-c though, we need to maintain backwards compatibility so we've modified LLVMFloatType() to internally use getGlobalContext(), and added LLVMFloatTypeInContext(LLVMContextRef) in order to explicitly choose which context to use. So, the question is what do we do with OCaml? Do we feel that we can break backwards compatibility and force passing around the LLVMContext, or should I follow llvm-c's lead, and add a bunch of *_in_context functions so that the API doesn'...

Hi, Just wondering if it's possible to construct a 128 bit quad precision floating point constant without converting the value back to a string.

...ing is that I must get a handle (LLVMValueRef) to the function and from that pull it's type as a LLVMTypeRef. This would be a 'function type', from which I can pull info about the return type and iterate the arguments, etc. At least, that's what I'm trying to do in my code: LLVMContextRef context = LLVMContextCreate(); LLVMMemoryBufferRef fileMemBuff; LLVMCreateMemoryBufferWithContentsOfFile( "test.bin", &fileMemBuff, &msg); LLVMModuleRef module; LLVMGetBitcodeModuleInContext( context, fileMemBuff, &module, &msg...
