[LLVMdev] LLVM: Very simple question
Hi, guys. I'm a newbie to LLVM and have a very simple question.
Which instructions should I use (in terms of IRBuilder calls) to allocate an
array of bytes in stack (alloca?), then to work with it (from a given
offset) as with integer (bitcast?). I mean something like that:
unsigned char var[8];
unsigned int offset = 3;
int val = *(int*)(&var+offset); /* read */
*(int*)(&var+offset)

[LLVMdev] Cast specific pointer type to generic one
Hi,
Suppose I have a pointer to "something" (a structure I defined) and I want
to pass the pointer to a generic function, that gets a 64-bit address
pointer.
How do I do that?
For instance:
The function is:
void Foo (void *);
I get the specific pointer using getPointerOperand() on a store instruction
that store to it:
inst->getPointerOperand()->getType()
Now I want

[LLVMdev] need to store the address of a variable
..."llc -march=cpp arndt.bc -f -o -" to see the C++ code that
constructs the module from the input bytecode. In your case, the
relevant section looks like this:
AllocaInst* ptr_a_addr = new AllocaInst(IntegerType::get(32), "a_addr",
label_4);
AllocaInst* ptr_d = new AllocaInst(PointerTy_1, "d", label_4);
StoreInst* void_5 = new StoreInst(int32_a /* argument %a */, ptr_a_addr,
false, label_4);
StoreInst* void_6 = new StoreInst(ptr_a_addr, ptr_d, false, label_4);
void_5 is putting the argument %a into the locally allocated %a_addr.
void_6 is taking %a_addr and storing it i...

[LLVMdev] need to store the address of a variable
Hello everybody,
my problem is, that I want to get an array of pointers to all local variables
in a function. This array will be used for transfering these Variables to
another execution engine.
I've code which generates this array, and a pointer to the target field of the
array.
name = variables.fname + "_pointerArray";
Instruction* pointerArray = new
