Hi,<br>
<br>
I have written a simple code to insert putchar() function into
IR. <br>
It compiled well but when I tried to run the generated .bc file
with lli, its not showing <br>
proper output.<br>
<br>
Function *putchar_func = cast<Function>(M-><br>
getOrInsertFunction("putchar",
IntegerType::getInt32Ty(Context),<br>
IntegerType::getInt32Ty(Context), NULL));<br>
<br>
Value *One = ConstantInt::get(Type::getInt32Ty(Context), 1);<br>
<br>
CallInst *CallFibX1 = CallInst::Create(putchar_func, One,
"fibx1", BB);<br>
CallFibX1->setTailCall();<br>

I'm assuming the program runs through lli but is not showing any
output.<br>
<br>
I think you're calling putchar() with a value of 1. That may be an
unprintable character (like ctrl-a). Try a value that is an ASCII
character (I think 'A' is 65, but it's been awhile).<br>
