Shaves off 368 bytes from the total size of all Unicode data tables.
This avoids having to add several unhelpful annotations when enabling diagnostic checks for `cpass` and `rpass` revisions.
This allows warnings to be annotated, and verifies that no unexpected warnings occur.
* Adds musl CVE fix to compiler section * Removes Cargo section per feedback in the PR
`DroplessArena::alloc` already disallows ZST allocation. `TypedArena::alloc` allows it but: - (a) it's never used, and - (b) writing to `NonNull::dangling()` seems dubious, even if the write is zero-sized. This commit just changes it to panic on a ZST. This eliminates an untested code path, and we shouldn't be allocating ZSTs anyway. It also eliminates an unused ZST code path in `clear_last_chunk`. Tests are also updated accordingly.

This adds a `--quiet` flag to x.py and bootstrap to suppress some of the output when compiling Rust. It conflicts with `--verbose`, matching the behavior of `cargo` which does not allow `--verbose` and `--quiet`. It works by passing quiet flags down to the underlying cargo, or LLVM build processes. Note that for LLVM, we only can suppress logs when we explicitly configure it with ninja. Otherwise we won't know what flag to pass along to whichever build system cmake decides to use. This can be helpful with AI workloads in the Rust codebase to help shrink down the output to reduce token usage, which can help prevent context pollution and lower costs. This patch was partially generated with Gemini, but I've reviewed the changes it made.

The queue is fairly long, so let's run a few try jobs in parallel while we're waiting. @bors try jobs=x86_64-msvc-1,i686-msvc-1,x86_64-mingw-1,test-various,armhf-gnu,aarch64-apple |
