make `ptr::rotate` smaller when using `optimize_for_size` code to reproduce https://github.com/folkertdev/optimize_for_size-slice-rotate In the example the size of `.text` goes down from 1624 to 276 bytes. ``` > cargo size --release --features "left-std" -- -A slice-rotate : section size addr .vector_table 1024 0x0 .text 1624 0x400 .rodata 0 0xa58 .data 0 0x20000000 .gnu.sgstubs 0 0xa60 .bss 0 0x20000000 .uninit 0 0x20000000 .debug_loc 591 0x0 .debug_abbrev 1452 0x0 .debug_info 10634 0x0 .debug_aranges 480 0x0 .debug_ranges 1504 0x0 .debug_str 11716 0x0 .comment 72 0x0 .ARM.attributes 56 0x0 .debug_frame 1036 0x0 .debug_line 5837 0x0 Total 36026 > cargo size --release --features "left-size" -- -A slice-rotate : section size addr .vector_table 1024 0x0 .text 276 0x400 .rodata 0 0x514 .data 0 0x20000000 .gnu.sgstubs 0 0x520 .bss 0 0x20000000 .uninit 0 0x20000000 .debug_loc 347 0x0 .debug_abbrev 965 0x0 .debug_info 4216 0x0 .debug_aranges 168 0x0 .debug_ranges 216 0x0 .debug_str 3615 0x0 .comment 72 0x0 .ARM.attributes 56 0x0 .debug_frame 232 0x0 .debug_line 723 0x0 Total 11910 ``` tracking issue: https://github.com/rust-lang/rust/issues/125612 |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
