As some of you might know, I have been researching and working on a region-based memory management plugin for GCC. My target is specifically the Go language. With that said, I have been making a fair amount of progress. More recently, I have been benchmarking my work, and it came to my attention that I need to handle types defined in an external object files. For instance, when a new List object is created, the external package for List, calls "new" and returns us a nice sparkly new List object. The runtime of Go implements "new" as "__go_new," which calls the runtime's special allocator to produce an object that is garbage collected. This is causing some snags in my system. Mainly, I want to use my own allocator, since there is only a special case when I want to use garbage collection in my region system. Is there a way/interface to register data as a root in the garbage collector, so that its not in conflict with my allocation?
The other option would be to try to override "__go_new" with my own implementation, but keeping the same symbol name so that the linker does the dirty work. -Matt
