f6dfc89a - Implement Aarch64AdrPrelPgHi21 and Aarch64AddAbsLo12Nc relocations in cranelift-object (#12824)

Tue, 24 Mar 2026 15:41:48 +0000

Implement Aarch64AdrPrelPgHi21 and Aarch64AddAbsLo12Nc relocations in cranelift-object (#12824)On aarch64 in non-PIC mode, colocated symbols (non-preemptible linkage)generate adrp+add instruction pairs with Aarch64AdrPrelPgHi21 andAarch64AddAbsLo12Nc relocations. These relocations were not handled incranelift-object's process_reloc, causing an unimplemented!() panic.Fixes #12818Co-authored-by: Claude Opus 4.6 (1M context) List of files: /wasmtime-44.0.1/cranelift/object/src/backend.rs

Another batch of dependency updates (#11832)* Another batch of dependency updatesBringing some deps in `Cargo.toml` up-to-date with their latest versionsalong the same lines as #11820 to avoid deps getting too stale/old.Code-wise this updates `anyhow` which enables preexisting Clippywarnings to check more code, so those warnings are fixed here as well.prtest:full* Run rustfmt List of files: /wasmtime-44.0.1/cranelift/object/src/backend.rs

2af0a1f7 - Introduce log2_min_function_alignment flag (#10391)

Thu, 13 Mar 2025 22:55:43 +0000

Introduce log2_min_function_alignment flag (#10391)* Remove function_alignment handling from cranelift-object and cranelift-jitIt is already handled by MachBuffer. The symbol_alignment could also beremoved as no current backend has a symbol alignment bigger than thefunction alignment, but keeping it around is a bit safer when newbackends are introduced.* Introduce log2_min_function_alignment flagThis is required for cg_clif to implement -Zmin-function-alignment.

ee818682 - Improvements to the subsection support in cranelift-object (#9742)

Thu, 05 Dec 2024 15:08:33 +0000

Improvements to the subsection support in cranelift-object (#9742)* Use a single section name for all subsectionsThis reduces the size of the object file as identical section names getdeduplicated.* Add a per_function_section equivalent for data objectsOn cg_clif's simple-raytracer benchmark this reduces the executable'ssize by 1MB from ~10MB to ~9MB. It does make lld slower though seeminglyunlike per_function_sections, so keeping this as separate flag isbeneficial for cg_clif.* Add link to PR List of files: /wasmtime-44.0.1/cranelift/object/src/backend.rs

f96aac79 - Deprecate Context::compile_and_emit (#9281)

Thu, 19 Sep 2024 15:18:01 +0000

Deprecate Context::compile_and_emit (#9281)The only thing it does over Context::compile is writing the machine codeto a Vec specified by the user. Every user of Context::compile_and_emitin Cranelift didn't actually need ownership over the machine code bytesand thus would have been able to use Context::compile instead to avoidan unnecessary allocation. This commit moves all in-tree users ofcompile_and_emit to compile and additionally to avoid other users addingan unnecessary allocation as they though it to be necessary, this commitadditionally deprecates compile_and_emit.
