No, there is no such page. We parse everything from 4.5, but have very limited support in codegen for target-specific directives, especially combined one. Moreover, some of them are not implemented at all and we may produce incorrect code. I can try to revisit
these "badly" supported constructs and provide some basic codegen to produce working code at least, though without actual offloading. But not sure that I will be able to do it quickly. <br>

Hi Hal,
<div>As soon as we get the support for 4.5, including offloading. Otherwise there always are going to be some people blaming the compiler for not supporting 4.5 in full. Will try to support it ASAP. </div>
<div>Meanwhile, you can use -fopenmp-version=45 option to force to 4.5 <br>

Thanks!<br>
<br>
Do we have a status page anywhere that shows where we stand on the various features? Are there still features that we don't parse, or where we don't generate something that conservatively correct (e.g., as with "declare simd")?<br>

<div><span>Hi, Alexey,</span><br>
<span></span><br>
<span>At what point can we switch, by default, to reporting a version for _OPENMP corresponding to 4.x? We're missing out on some OpenMP simd directives because the source code guards them with '#if _OPENMP >= 201307' or similar.</span><br>
<span></span><br>
<span>Thanks again,</span><br>
