[LLVMdev] How to retrieve IntToPtr from StoreInst?
hi,
i am writing a simple LLVM pass to analyze the Store instruction.
my pass derives from InstVisitor class, and the method to handle Store
instruction is like this:
void MyPass::visitStoreInst(StoreInst &I) {
...
}
It is pretty simple to handle Store. however, in on test i got an
instruction like below:
store i8 %tmp5, i8* inttoptr (i32 301959828 to i8*)
the second operand is "i8* inttoptr (i32 301959828 to i8*)", and i have no
idea how i can retrieve the address 30195...

The inttoptr used here is a Constant Expression (llvm::ConstantExpr).

[LLVMdev] Determine whether a stored variable is local or global in the code of LLVM 2.7
Hi,
I am trying to modify visitStoreInst() function in Execution.cpp of LLVM 2.7
to do some extra things. How I can determine whether the stored variable is
global or local for some function?
Regards,
Nayden

[LLVMdev] InstVisitor usage problem
...my pass is like that:
using namespace llvm;
namespace
{
class InstVisit : public ModulePass,
public InstVisitor<InstVisit>
{
public :
static char ID;
InstVisit():ModulePass(ID){}
virtual bool runOnModule(Module &M)
{
visit(M);
return false;
}
void visitStoreInst(StoreInst &SI)
{
errs()<<"a store inst:"<<&SI<<"\n";
}
};
char InstVisit::ID = 0;
static RegisterPass<InstVisit>
X("visitInst","visit inst test");
}
then I use

[LLVMdev] reference to non-static member function must be called
I'm using LLVM 3.3 Release. From the Class Reference Page. CallInst has a
member function :
static CallInst * Create (Value *Func, ArrayRef< Value * > Args, const
Twine &NameStr="", Instruction *InsertBefore=0)
This is what I want to use! the default name is "" and I also use that .
Thanks!

[LLVMdev] reference to non-static member function must be called
Hi,everyone.
I'm writing a pass in which a CallInst to an external function will be
inserted. The function is declared like this:
void func(int a, unsigned chat *p);
and in the Pass(a Function Pass ,and using the InstVistor template ), I
wrote like this:
void visitStoreInst(StoreInst &SI)
{
//Get the refference of the types
Module *M = SI.getParent()->getParent()->getParent();
IntegerType* Int8Type = IntegerType::getInt8Ty(M->getContext());
IntegerType* Int32Type = IntegerType::getInt32Ty(M->getContext());
IntegerType* Int64Type = In...

Why getNumOperands() incorrectly returns 0?
Hi all,
I have encountered a weird case that I cannot understand. Inside the
visitStoreInst I have a reference (F) to the function png_set_mem_fn. If I
do F->dump() i can set the IR of that function correctly e.g.:
; Function Attrs: nounwind uwtable
define void @png_set_mem_fn(%struct.png_struct_def.68* noalias %png_ptr,
i8* %mem_ptr, i8* (%struct.png_struct_def.68*, i64)* %malloc_fn,...

[LLVMdev] question about enabling cfl-aa and collecting a57 numbers
...rand directly , but such is life ...
CFL-AA *should* treat this like an assignment to GEP operand, not like a
normal store, which is *x = y. This is really *(&GEP operand) = y.
But currently, it does nothing right here :)
I haven't tracked down entirely what is happening, but for sure,
visitStoreInst doesn't do the right thing in this case.
Fixing that still gives a wrong result, i haven't started to track down
what *else* is going on here.
I suspect either more ConstantExpr related bugs, or the global attribute
is not being fully propagated around or something.

...al Alias Queries Performed
176 no alias responses (33.7%)
- 334 may alias responses (64.1%)
- 10 partial alias responses (1.9%)
+ 344 may alias responses (66.0%)

1 must alias responses (0.1%)
I suspect this is all caused by a different set of bugs:
1. visitStoreInst does not appear to handle the case of value being a GEP
properly (Personally, i had no idea this was allowed ...)
It should somehow call into the visitGEP code, but it doesn't.
Thus, it never assigns anything into the value of the global.
2. Something is either busted in querying or in attribu...

Interpreter crash due to an "Unknown constant pointer type!"
Hi David,
In pretty sure that the crash is due to the instruction I have shared in my
first email. In order to run pngpixel you just need libpng and zlib..
honest I thought that the .bc had Al the necessary. I'm happy to help you
to reproduce it. As a curiosity, why do you think you cannot reproduce it?
Unfortunately I won't be able to modify the interpreter soon.. anyway, I'll
