re-gimplifing things when variables have been replaced with complex
expressions.
- Lowering of a parallel statement results in the contents of the
- parallel being moved to a new function, to be invoked by the thread
- library. The variable remapping process is complex enough that only
- one level of parallel statement is handled at one time. If there are
- nested parallel statements, those nested statements are handled when
- the new function is lowered and optimized. The result is not 100%
- optimal, but lexically nested parallels effectively only happens in
- test suites. */
+ Final code generation is done by pass_expand_omp. The flowgraph is
+ scanned for parallel regions which are then moved to a new
+ function, to be invoked by the thread library. */
