--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- The issue is that someone needs to go through all the parsing for OpenMP constructs, and figure out exactly where to add calls to convert_lvalue_to_rvalue (if an OpenMP construct reads the value of an object, reading the value of an _Atomic object must be an atomic load) and what other special handling might be needed (if an OpenMP construct writes to an object, it must be an atomic store; if it both reads and writes, some form of compare-and-exchange may be needed).
