87ed3b60 - Cranelift: make all non-tail, non-indirect calls patchable, and rename patchable ABI to `preserve_all`. (#12160)

Mon, 15 Dec 2025 23:29:06 +0000

Cranelift: make all non-tail, non-indirect calls patchable, and rename patchable ABI to `preserve_all`. (#12160)* Cranelift: make all non-tail, non-indirect calls patchable, and rename patchable ABI to `preserve_all`.As discussed in this week's Cranelift meeting, we've discovered a needto generalize the `patchable_call` mechanism and corresponding`patchable` ABI slightly. In particular, we will need patchable`try_call` callsites as well in order to allow breakpoint handlers tothrow exceptions (desirable functionality eventually) and have this workin the presence of inlining. Also, it's just a nice generalization tosay that patchability is an orthogonal dimension to the call ABI and theother restrictions we initially imposed, and works as long as the basicrequirement (no return values) is met.This also renames the `patchable` ABI to `preserve_all`, to make itclear that its purpose is actually orthogonal, and it can be usedindependently of patchable callsites. It also deletes the `cold` ABI,which never actually did anything and is misleading in the presence ofan actual cold-ish (subzero temperature, actually) ABI like`preserve_all`.* Review feedback.

9ec02f9d - Decouple `serde` from its `derive` crate (#6917)

Tue, 29 Aug 2023 16:02:06 +0000

Decouple `serde` from its `derive` crate (#6917)By not activating the `derive` feature on `serde`, the compilation speedcan be improved by a lot. This is because `serde` can then compile inparallel to `serde_derive`, allowing it to finish compilation possiblyeven before `serde_derive`, unblocking all the crates waiting for`serde` to start compiling much sooner.As it turns out the main deciding factor for how long the compile time of aproject is, is primarly determined by the depth of dependencies ratherthan the width. In other words, a crate's compile times aren't affectedby how many crates it depends on, but rather by the longest chain ofdependencies that it needs to wait on. In many cases `serde` is part ofthat long chain, as it is part of a long chain if the `derive` featureis active:`proc-macro2` compile build script > `proc-macro2` run build script >`proc-macro2` > `quote` > `syn` > `serde_derive` > `serde` >`serde_json` (or any crate that depends on serde)By decoupling it from `serde_derive`, the chain is shortened and compiletimes get much better.Check this issue for a deeper elaboration:https://github.com/serde-rs/serde/issues/2584For `wasmtime` I'm seeing a reduction from 24.75s to 22.45s whencompiling in `release` mode. This is because wasmtime through `gimli`has a dependency on `indexmap` which can only start compiling when`serde` is finished, which you want to happen as early as possible sosome of wasmtime's dependencies can start compiling.To measure the full effect, the dependencies can't by themselvesactivate the `derive` feature. I've upstreamed a patch for`fxprof-processed-profile` which was the only dependency that activatedit for `wasmtime` (not yet published to crates.io). `wasmtime-cli` andco. may need patches for their dependencies to see a similarimprovement.

91d1d246 - Allow serializing all cranelift-module data structures (#6172)

387426e7 - cranelift: improve syscall error/oom handling in JIT module (#5173)

Thu, 03 Nov 2022 23:59:41 +0000

cranelift: improve syscall error/oom handling in JIT module (#5173)* cranelift: improve syscall error/oom handling in JIT module The JIT module has several places where it `expect`s or `panic`s on syscall or allocator errors. For example, `mmap` and `mprotect` can fail if Linux `vm.max_map_count` is not high enough, and some users may wish to handle this error rather than immediately crashing. This commit plumbs these errors upward as new `ModuleError` types, so that callers of jit module functions like `finalize_definitions` and `define_function` can handle them (or just `unwrap()`, as desired). * cranelift: Remove ModuleError::Syscall variant Syscall errors can just be folded into the generic Backend error, which is an anyhow::Error * cranelift-jit: return io::ErrorKind::OutOfMemory for alloc failure Just using `io::Error::last_os_error()` is not correct as global allocator impls are not required to set errno List of files: /wasmtime-44.0.1/cranelift/module/src/module.rs
