when I originally implemented that for metadirectives on the OG13 branch about a year ago, only C++ had general support for attribute syntax. My C++ testcases failed to "just work" in C because the lookahead save/restore mechanism for attribute directives collided with the token caching used by metadirective for parsing the body. So I fixed that, now the testcases work in both languages. Also note the lists of improvements and bug fixes for previous versions of the patch set, which I won't duplicate here. I realize this is a large and complicated patch set with many dependencies between the pieces (and I have another layer on top of this in the works to support "begin declare variant"). If the maintainers would find it easier to review if I refactored the pieces in some other way, please let me know what would help to expedite the process. I'd really like to get these patches in somehow or another, so I don't have to continue to spend so much time maintaining them out of tree. :-S -Sandra Sandra Loosemore (12): OpenMP: metadirective tree data structures and front-end interfaces OpenMP: middle-end support for metadirectives libgomp: runtime support for target_device selector OpenMP: C front end support for metadirectives OpenMP: C++ front-end support for metadirectives OpenMP: common c/c++ testcases for metadirectives OpenMP: Fortran front-end support for metadirectives.
