retool MIR passes completely The new setup is as follows. There is a pipeline of MIR passes that each run per def-id to optimize a particular function. You are intended to request MIR at whatever stage you need it. At the moment, there is only one stage you can request: - `optimized_mir(def_id)` This yields the final product. Internally, it pulls the MIR for the given def-id through a series of steps. Right now, these are still using an "interned ref-cell" but they are intended to "steal" from one another: - `mir_build` -- performs the initial construction for local MIR - `mir_pass_set` -- performs a suite of optimizations and transformations - `mir_pass` -- an individual optimization within a suite So, to construct the optimized MIR, we invoke: mir_pass_set((MIR_OPTIMIZED, def_id)) which will build up the final MIR. 2017-04-27 16:48:48 -04:00
Move the dataflow framework to its own crate. 2021-01-05 19:53:07 +01:00			`pub use rustc_middle::mir::MirPass;`
