bors 4573a4a879 Auto merge of #86383 - shamatar:slice_len_lowering, r=bjorn3 ... Add MIR pass to lower call to `core::slice::len` into `Len` operand During some larger experiment with range analysis I've found that code like `let l = slice.len()` produces different MIR then one found in bound checks. This optimization pass replaces terminators that are calls to `core::slice::len` with just a MIR operand and Goto terminator. It uses some heuristics to remove the outer borrow that is made to call `core::slice::len`, but I assume it can be eliminated, just didn't find how. Would like to express my gratitude to `@oli-obk` who helped me a lot on Zullip		2021-06-21 22:24:13 +00:00
