[PATCH 0/7] openmp: OpenMP metadirectives support

[Kwok Cheung Yeung]

Hello

This is my current patchset for OpenMP metadirectives support. It aims 
to implement the specification from OpenMP 5.1, with dynamic selector 
support (though currently only the dynamic user selector set is 
supported), and supports the C, C++ and Fortran front ends.

The patch has been bootstrapped on a x86_64 Linux machine, and the 
testsuite run with no regressions (libgomp tested with both no 
offloading and with offloading to nvptx). Okay for inclusion in trunk?
