RUSTC ROLLUP LANDS XTENSA SUPPORT, CRATES.IO FIXES SELF-REFERENCING BLOCKS

The compiler gained a major new architecture target while the registry fixed a deletion blocker that was trapping maintainers with circular dependencies.

The rust compiler inbox is moving fast. A 13-PR rollup landed overnight [1] that includes Xtensa architecture support for inline assembly, the first real implementation of compile-time function evaluation, and a new proc-macro `_value` API for number literals. These aren't incremental; Xtensa is a significant embedded win, and comptime functions open new doors for const evaluation. On the registry side, crates.io fixed a critical oversight where self-referencing dependencies were blocking crate deletion [2]. Maintainers trying to clean up old versions were getting trapped because the deletion check couldn't distinguish between legitimate reverse dependencies and a crate depending on itself. That's resolved now. The http crate bumped to 1.4.2 [3] with a fix allowing `"*"` as a valid URI path in the builder, a small but necessary correction for HTTP spec compliance. Meanwhile, the regex team landed a significant performance win [4] by avoiding repeated canonicalization of huge IntervalSets on push operations, addressing a real-world bottleneck hit by lalrpop-generated lexers with massive character ranges. Observability work continues at crates.io with new logging conventions [5] and better error interpolation into messages [6], making the backend easier to debug in production.
