bors 537aab7a2e Auto merge of #120131 - oli-obk:pattern_types_syntax, r=compiler-errors Implement minimal, internal-only pattern types in the type system rebase of https://github.com/rust-lang/rust/pull/107606 You can create pattern types with `std::pat::pattern_type!(ty is pat)`. The feature is incomplete and will panic on you if you use any pattern other than integral range patterns. The only way to create or deconstruct a pattern type is via `transmute`. This PR's implementation differs from the MCP's text. Specifically > This means you could implement different traits for different pattern types with the same base type. Thus, we just forbid implementing any traits for pattern types. is violated in this PR. The reason is that we do need impls after all in order to make them usable as fields. constants of type `std::time::Nanoseconds` struct are used in patterns, so the type must be structural-eq, which it only can be if you derive several traits on it. It doesn't need to be structural-eq recursively, so we can just manually implement the relevant traits on the pattern type and use the pattern type as a private field. Waiting on: * [x] move all unrelated commits into their own PRs. * [x] fix niche computation (see 2db07f94f44f078daffe5823680d07d4fded883f) * [x] add lots more tests * [x] T-types MCP https://github.com/rust-lang/types-team/issues/126 to finish * [x] some commit cleanup * [x] full self-review * [x] remove 61bd325da19a918cc3e02bbbdce97281a389c648, it's not necessary anymore I think. * [ ] ~~make sure we never accidentally leak pattern types to user code (add stability checks or feature gate checks and appopriate tests)~~ we don't even do this for the new float primitives * [x] get approval that [the scope expansion to trait impls](https://rust-lang.zulipchat.com/#narrow/stream/326866-t-types.2Fnominated/topic/Pattern.20types.20types-team.23126/near/427670099) is ok r? `@BoxyUwU`		2024-04-08 16:25:23 +00:00

README.md

The files here use the LLVM FileCheck framework, documented at https://llvm.org/docs/CommandGuide/FileCheck.html.

One extension worth noting is the use of revisions as custom prefixes for FileCheck. If your codegen test has different behavior based on the chosen target or different compiler flags that you want to exercise, you can use a revisions annotation, like so:

// revisions: aaa bbb
// [bbb] compile-flags: --flags-for-bbb

After specifying those variations, you can write different expected, or explicitly unexpected output by using <prefix>-SAME: and <prefix>-NOT:, like so:

// CHECK: expected code
// aaa-SAME: emitted-only-for-aaa
// aaa-NOT:                        emitted-only-for-bbb
