It will be bumped for 1.83 as tagged in the pull request.> It leads > me to wonder if lang/rust should be using an external From using pkg to update to the recent official lang/rust distribution: # rustc -vV rustc 1.82.0 (f6e511eec 2024-10-15) (built from a source tarball) binary: rustc commit-hash: f6e511eec7342f59a25f7c0534f1dbea00d01b14 commit-date: 2024-10-15 host: x86_64-unknown-freebsd release: 1.82.0 LLVM version: 19.1.1 So the internal LLVM for lang/rust is LLVM 19.1.1 based as of that update. It is not my build, but is the official FreeBSD one for main [so: 15 as stands].

The only way the internal LLVM for lang/rust ends up being based on LLVM 18 for 1.82.0 is via use of PORT_LLVM , which the official FreeBSD package builders do not do (at this time). So lang/rust 1.82.0 builds can potentially have newer, LLVM 19 specific material if there is such. >> devel/llvm* by default, set to match a default ports tree >> LLVM to be used for major ports that involve lang/rust use. > No. Not something upstream encourages by default even if support exists, > especially because the default upstream builds use the bundled LLVM which is > what most consumers qualify with. The FreeBSD may at times have to update such that the default LLVM is forced to well match the lang/rust default LLVM. That might mean not updating lang/rust . (I'm not claiming there are always conflicts to deal with when LLVM's mismatch, just that there could be such at times.) === Mark Millard marklmi at yahoo.com
