...c = dyn_cast <ConstantExpr>(op2)) { // how to extract the Int Constant here? } } The problem is that given ConstantExpr, i am not sure how to extract the Int Constant operand. According to http://llvm.org/doxygen/classllvm_1_1ConstantExpr.html, this class only provides method such as getWithOperands(), but this method doesnt seem to do what I want. I grep through the code of LLVM, but cannot find any example doing this. any more hint, please? Thanks, Jun -------------- next part -------------- An HTML attachment was scrubbed...

Thanks Duncan, Yes, it is a ConstantExpr! Thank you! Now trying to find a clue in ConstantExpr's functions to get that string :-) Regards, Welson On Thu, Jan 26, 2012 at 9:04 PM, Duncan Sands <baldrick at free.fr> wrote: > Hi Welson Sun, > > > Hi, if I have some LLVM code like this: > > > > @.str = private unnamed_addr constant [7 x i8]

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

Hi Sanjay, Thanks, I saw this flag and it's definitely should be considered, but it appeared to me to be static characteristic of target platform. I'm not sure how appropriate it would be to change its value from a front-end. It says "Has", while optional flag would rather say "Uses" meaning that implementation cares about floating point exceptions. Regards, Sergey
