<p class="MsoNormal">Hi Kiran,<br>
<br>
Vector pgmath routines are present in the Flang libraries, however the Flang front end only generates scalar pgmath calls.<br>
<br>
The LLVM vectorizer has been modified to recognize scalar pgmath calls and generate appropriate vector calls. Here’s the PR that introduced this change if you’re interested:<br>

Are vector pgmath symbols called directly in Flang? Are they directly used in the Flang libraries?<o:p></o:p></span></p>
