This page contains information on GCC's implementation of the OpenMP standard and related functionality like the auto parallelizer (-ftree-parallelize-loops).
As of GCC 4.2, the compiler implements version 2.5 of the OpenMP standard and as of 4.4 it implements version 3.0 of the OpenMP standard. The OpenMP 3.1 is supported since GCC 4.7.

Feel free to add new items to this list as you run into issues or features that would be interesting to add. Send mail to the list and/or the GCC OpenMP maintainers if any item in this list sounds interesting but is hard to understand.
Fix PR 35423 (missing parts of OpenMP WORKSHARE).
Fine tune the auto scheduling feature for parallel loops.
Implement untied tasks (no compliance issue; needs to be well tuned to be actually faster; cf. page 53 of pdf) - see also next item
Note: There is a GSoC 2011 project regarding task and untied tasks
