Small Perl task for the interested Want to get involved in the Parrot development process? Don't know much about Virtual Machine design and implementation? Do know Perl? Dan has a small but interesting task for you.
At present, Parrot gets built without any compiler level optimizations turned on because files like tsq.c can't have any optimizations turned on (tsq.c is the thread safe queue module, which is "annoyingly execution-order-dependent because it has to operate safely as interrupt code potentially interrupting itself").
Dan would like a version of Configure.pl which can build a makefile (or whatever build tool we end up using) with per-C-file compiler flags, and it needs to be possible to override those flags, per file, by the platform configuration module.
Hmm, I'm only a lurker, but that looks *very* suspect to me. Some compilers may choose to reorder even without optimization turned on. I'd say that it is a bug in Parrot if it requires optimization to be off for this code - how many different compilers have you tried?
