Dear llvm-dev community,<br>
   I am trying to analyze the optimization remarks generated through clang<br>
using -fsave-optimization-remark with -O3.<br>
<br>
--- !Analysis<br>
Pass: loop-vectorize<br>
Name: CFGNotUnderstood<br>
DebugLoc: { File: c-ray-mt.c, Line: 177, Column: 2 }<br>
Function: main<br>
Args:<br>
- String: 'loop not vectorized: '<br>
- String: loop control flow is not understood by vectorizer<br>
<br>
<br>
I tried to look for information about "loop vectorize pass" and other<br>
emitted pass in the official llvm passes documentaiton here<br>
<<a href="https://llvm.org/docs/Passes.html" rel="noreferrer" target="_blank">https://llvm.org/docs/Passes.html</a>> but it is not there. Please let me know<br>
where to find information about passes emitted in the optimization report.<br>
<br>
Regards,<br>
Pradeep<br><br>
