rust/tests/mir-opt/pre-codegen
History
Jacob Pratt 1ba9b7873a Rollup merge of #138135 - scottmcm:chaining-ord, r=Mark-Simulacrum 
Simplify `PartialOrd` on tuples containing primitives

We noticed in https://github.com/rust-lang/rust/pull/133984#issuecomment-2704011800 that currently the tuple comparison code, while it [does optimize down](https://github.com/rust-lang/rust/blob/master/tests/codegen/comparison-operators-2-tuple.rs) today, is kinda huge: <https://rust.godbolt.org/z/xqMoeYbhE>

This PR changes the tuple code to go through an overridable "chaining" version of the comparison functions, so that for simple things like `(i16, u16)` and `(f32, f32)` (as seen in the new MIR pre-codegen test) we just directly get the
```rust
if lhs.0 == rhs.0 { lhs.0 OP rhs.0 }
else { lhs.1 OP rhs.1 }
```
version in MIR, rather than emitting a mess for LLVM to have to clean up.

Test added in the first commit, so you can see the MIR diff in the second one.

README.md

The goal of this directory is to track the quality of MIR that is given to codegen in a standard -O condiguration.

As such, feel free to --bless whatever changes you get here, so long as doing so doesn't add substantially more MIR.
