History

Stuart Cook 9c73bcfa8d Rollup merge of #130225 - adetaylor:rename-old-receiver, r=wesleywiser Rename Receiver -> LegacyReceiver As part of the "arbitrary self types v2" project, we are going to replace the current `Receiver` trait with a new mechanism based on a new, different `Receiver` trait. This PR renames the old trait to get it out the way. Naming is hard. Options considered included: * HardCodedReceiver (because it should only be used for things in the standard library, and hence is sort-of hard coded) * LegacyReceiver * TargetLessReceiver * OldReceiver These are all bad names, but fortunately this will be temporary. Assuming the new mechanism proceeds to stabilization as intended, the legacy trait will be removed altogether. Although we expect this trait to be used only in the standard library, we suspect it may be in use elsehwere, so we're landing this change separately to identify any surprising breakages. It's known that this trait is used within the Rust for Linux project; a patch is in progress to remove their dependency. This is a part of the arbitrary self types v2 project, https://github.com/rust-lang/rfcs/pull/3519 https://github.com/rust-lang/rust/issues/44874 r? `@wesleywiser`		2024-10-24 14:19:53 +11:00

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
// bbb-NOT:  emitted-only-for-aaa
// bbb-SAME:                       emitted-only-for-bbb
