Hi all,<div><br></div><div>I am trying to do an analysis of a parallelized code using sse optimizations. The problem I am encountering is that I need to do some matching based on the analysis and I would like to extract the names of the functions as is rather than llvm intrinsics with an llvm. representation. Essentially I would like to extract the control flow graph representation with function names (eg. <span class="Apple-style-span" style="font-family: 'Courier New'; ">_mm_cvtsi32_si128<span class="Apple-style-span" style="font-family: arial; ">) instead of the functions being replaced by 'llvm.*'</span></span></div>
<div><br></div><div>Is there anyway to extract these names directly as function calls?</div><div><br></div><div><br></div><div>I have included the sample code below.</div><div><br></div><div>I get the function call names as llvm.x86 something instead of getting function names(eg. <span class="Apple-style-span" style="font-family: 'Courier New'; ">_mm_cvtsi32_si128<span class="Apple-style-span" style="font-family: arial; ">) </span></span></div>
