<div dir="ltr"><div><div>Hello,<br><br></div>I'm compiling my C code to IR, using opt and then compiling into a binary. I'm getting different runtimes when I use 'opt -O1' and when I use 'opt -debug-pass=Arguments' and then copy the list of flags into opt. Why could this be?<br>
<br></div><div>Essentially I'm trying to track down which optimizations cause a speedup (so I extracted the list of optimizations and am running opt repeatedly with individual optimizations removed).<br><br></div><div>
Thanks, <br></div><div>Peter<br></div></div>
