@wesleywiser Do you know why check builds get optimized MIR?
cc @rust-lang/compiler

Aaron1011 · 2020-02-04T00:32:27Z

According to the dep graph, it's coming from const_eval_raw, probably here:

rust/src/librustc_mir/interpret/eval_context.rs

Line 327 in 0859451

Ok(self.tcx.optimized_mir(did).unwrap_read_only())

Zoxc · 2020-02-04T00:57:44Z

Well unicode_normalization has a large constant. Maybe we're copying that due to inlining?

wesleywiser · 2020-02-04T02:11:53Z

I didn't know we did that either. I guess for consts coming from other crates, the only MIR we have is from the optimized_mir query?
