Two unfortunate allocations were wrapping a proc() in a proc() with GreenTask::build_start_wrapper, and then boxing this proc in a ~proc() inside of Context::new(). Both of these allocations were a direct result from two conditions: 1. The Context::new() function has a nice api of taking a procedure argument to start up a new context with. This inherently required an allocation by build_start_wrapper because extra code needed to be run around the edges of a user-provided proc() for a new task. 2. The initial bootstrap code only understood how to pass one argument to the next function. By modifying the assembly and entry points to understand more than one argument, more information is passed through in registers instead of allocating a pointer-sized context. This is sadly where I end up throwing mips under a bus because I have no idea what's going on in the mips context switching code and don't know how to modify it. Closes #7767 cc #11389 |
