It is only used within cg_llvm.
It is always false nowadays. ThinLTO summary writing is instead done by llvm_optimize.
Upstream Solaris flock emulation to libstd from cargo. This is borrowed from https://github.com/rust-lang/cargo/blob/3b379fcc541b39321a7758552d37e5e0cc4277b9/src/cargo/util/flock.rs#L502-L536 which was implemented by an Oracle employee. The code has been in cargo since 2022-12. Python's `fcntl.flock` emulates like this as well: https://github.com/python/cpython/blob/c919d02edecfe9d75fe374756fb8aa1db8d95f55/Modules/fcntlmodule.c#L337-L400 We did the same thing in https://github.com/rust-lang/rust/blob/0d0f4eac8b98133e5da6d3604d86a8f3b5a67844/compiler/rustc_data_structures/src/flock/unix.rs#L13-L39
…crum fix: offline rustdoc html missing favicon As discussed in the rust-lang#146149 the doc was missing the favicon icon when build locally and viewed on a browser. I changed the relative path and also now we explicitly copy both SVG and PNG. <img width="1132" height="425" alt="Screenshot 2025-09-03 at 11 57 46 PM" src="https://github.com/user-attachments/assets/062cbb08-04ec-4d88-a43a-710fb6190f82" />
Misc LTO cleanups Follow up to rust-lang#145955. * Remove want_summary argument from `prepare_thin`. Since rust-lang#133250 ThinLTO summary writing is instead done by `llvm_optimize`. * Two minor cleanups
…mulacrum feat(std): emulate flock for solaris via fcntl Upstream Solaris flock emulation to libstd from cargo. This is borrowed from https://github.com/rust-lang/cargo/blob/3b379fcc541b39321a7758552d37e5e0cc4277b9/src/cargo/util/flock.rs#L502-L536 which was implemented by an Oracle employee.

…ethlin Introduce PlaceContext::may_observe_address. A small utility method to avoid open-coding the logic in several MIR opts.
