Summary

The FreeBSD-clang package contains a 32-bit shared object at
/usr/lib/clang/19/lib/freebsd/libclang_rt.asan-i386.so

This is expected, since clang uses this object when compiling for i386
targets with asan enabled.

What is not expected is that the FreeBSD-clang package currently depends
on 32-bit libc packages due to pkg's shared library analysis, making it
impossible to install pkgbase on x86_64 without any lib32 packages.

This commit leverages a new pkg feature implemented in [1], but could
be landed before a pkg version including that feature is released
without any ill effects. Unknown keys in package manifests are ignored.

Won’t that break the dependencies list if clang is itself 32-bit? This also introduces a new hard-coding of the set of compat libraries rather than using _ALL_libcompats.

No, it shouldn't break when building src for a 32-bit target. The :32 is appended by pkg only when pkg config ABI is amd64, aarch64, or powerpc64 and it finds a shared library for the corresponding 32-bit architecture. On a fully 32-bit system there would be no :32.

This also introduces a new hard-coding of the set of compat libraries rather than using _ALL_libcompats.

Upstream pkg does not know about _All_libcompats and only supports detecting and handling 32-bit and linux compat libraries separately. Support for differentiating libraries for other libcompats would need to be implemented in upstream pkg.

ifreund_freebsdfoundation.org mentioned this in D55978: EC2: Add clibs-lib32 pkg to small/builder images.Tue, Apr 7, 3:55 PM

The new pkg feature used by this patch was released in pkg 2.6.0 on March 3rd. I think this is ready to land.
