<html><body><p><font size="2">Hi Daniel,</font><br><br><font size="2">As Jonas said, support for declare target has not been upstreamed yet. I am working on this right now. There is a Sema patch under review, once it gets accepted I'll also upstream the codegen patch. Hopefully we'll get done with this soon.</font><br><br><font size="2">George</font><br><br><img width="16" height="16" src="cid:1__=0ABB0B7ADFFED5888f9e8a93df938690918c0AB@" border="0" alt="Inactive hide details for Daniel Schürmann via Openmp-dev ---01/12/2017 10:18:42---Hello!
