许杰友 Jieyou Xu (Joe)	10b8ba4ecb	Mark simplify_aggregate_to_copy mir-opt as unsound ... Co-authored-by: DianQK <dianqk@dianqk.net>	2024-10-31 13:48:06 +08:00
Nathan Perry	d793766a61	liballoc: introduce String, Vec const-slicing ... This change `const`-qualifies many methods on Vec and String, notably `as_slice`, `as_str`, `len`. These changes are made behind the unstable feature flag `const_vec_string_slice` with the following tracking issue: https://github.com/rust-lang/rust/issues/129041	2024-10-06 19:58:35 -04:00
DianQK	c16c22cc9c	Simplify the canonical clone method to copy ... The optimized clone method ends up as the following MIR: ``` _2 = copy ((*_1).0: i32); _3 = copy ((*_1).1: u64); _4 = copy ((*_1).2: [i8; 3]); _0 = Foo { a: move _2, b: move _3, c: move _4 }; ``` We can transform this to: ``` _0 = copy (*_1); ```	2024-09-14 13:30:35 +08:00

Scott McMurray	0d63e6b608	[ACP 362] genericize ptr::from_raw_parts	2024-05-29 09:34:16 -07:00
Scott McMurray	61517dbbe6	Avoid a cast in ptr::slice_from_raw_parts(_mut) ... Casting to `*const ()` or `*mut ()` just bloats the MIR, so let's not. If ACP#362 goes through we can keep calling `ptr::from_raw_parts(_mut)` in these also without the cast, but that hasn't had any libs-api attention yet, so I'm not waiting on it.	2024-05-06 01:53:54 -07:00
