<div dir="ltr">Dear all,<div><br></div><div><br></div><div>I'm writing an LLVM pass, and I want to insert a call instruction that takes a function pointer as a parameter. The effect would be the same as following:</div><div><br></div><div>atexit(foo);</div><div><br></div><div>Where foo is a function I insert with M.getOrInsertFunction(), which in LLVM is a Function class.</div><div><br></div><div>I searched for a while and did not come up with a satisfying answer. Should I create a Value class of pointer type, or a Int64Ty for a pointer? How do I get the pointer to the function I create? I also tried passing foo as Function* in LLVM as parameter to create CallInst directly, and I doesn't seem to work.</div><div><div><br></div><div>Any hints and enlightenment is appreciated. Many thanks.</div><div><br></div><div><br></div>Regards,<br><div class="gmail_signature"><div dir="ltr">Yours,<div>Kevin Hu</div></div></div>
