This will require updates to the Static SDK build job, because it changes the versions of dependencies and adds some dependencies. Also, we will need to check the licensing situation before merging this. |
Updated the versions of: - libxml2 (2.14.5) - curl (8.15.0) - BoringSSL (newer SHA) and added: - bzip2 (1.0.8) - xz-utils (5.8.1) - libarchive (3.8.1) - mimalloc (2.2.4) Plus two security patches for musl to fix CVE-2025-26519. Also link mimalloc by default, so programs using the Static SDK for Linux get a better memory allocator out of the box. rdar://156423711

We need to run the build and install of bzip2 together, otherwise bzip2 tries to run tests, which won't necessarily work when cross compiling for a different architecture. We also want to remove various directories from the final result. Oh, and we don't want to build libxml2 with lzma support either, otherwise we'll have to link with liblxma whenever we use libxml2.

To do this properly, we remove all of the allocator implementation from `libc.a` and `libc++abi.a`, and add `mimalloc.o`, mimalloc's static implementation, directly to `libc.a`.

Ideally we should land swiftlang/swift#84705 and swiftlang/swift#84706 first, as that will mean that all builds of the 0.1.0 version of the Static SDK for Linux will have library evolution disabled. That seems cleaner than landing this one first. |
