[LLVMdev] How to load a data from the address of unsiged long type
...astInst to vern):
Value* addr = CONST(0xc0008000);
a = new BitCastInst(a, PointerType::get(XgetType(Int32Ty), 0), "", bb);
Value* data = new LoadInst(addr, "", false, bb);
Error:
Bitcast requires types of same width
3. Code:
Type const *intptr_type =
cpu->dyncom_engine->exec_engine->getTargetData()->getIntPtrType(_CTX());
Value* ptr = new IntToPtrInst(a, intptr_type, "", bb);
Value* data = new LoadInst(ptr, "", false, bb);
Error:
Segmentation fault
Any person can give me some hints...

...LLVM so you get an assert
message instead of a segfault. Here you're trying to load from an
