History

Rollup merge of #147457 - the8472:slice_fill_memset2, r=RalfJung,joboet

specialize slice::fill to use memset when possible

It helps const eval performance https://github.com/rust-lang/miri/issues/4616, debug builds and the gcc backend.

Previously attempted in https://github.com/rust-lang/rust/pull/83245 but reverted due to unsoundness https://github.com/rust-lang/rust/issues/87891 around potentially-uninitialized types. This PR only handles primitives where the problem does not arise.

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
