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/tests/basic.rs

`cranelift-frontend`: Refactor how variables are declared (#10965)* cranelift-frontend: Refactor how variables are declaredRather than requiring users to construct a `Variable` entity out of thin airand *then* declare it to the frontend, declaring a new variable now returns thenew `Variable` entity.

8a9b1a90 - Implement an incremental compilation cache for Cranelift (#4551)

Fri, 12 Aug 2022 16:47:43 +0000

Implement an incremental compilation cache for Cranelift (#4551)This is the implementation of https://github.com/bytecodealliance/wasmtime/issues/4155, using the "inverted API" approach suggested by @cfallin (thanks!) in Cranelift, and trait object to provide a backend for an all-included experience in Wasmtime. After the suggestion of Chris, `Function` has been split into mostly two parts: - on the one hand, `FunctionStencil` contains all the fields required during compilation, and that act as a compilation cache key: if two function stencils are the same, then the result of their compilation (`CompiledCodeBase`) will be the same. This makes caching trivial, as the only thing to cache is the `FunctionStencil`. - on the other hand, `FunctionParameters` contain the... function parameters that are required to finalize the result of compilation into a `CompiledCode` (aka `CompiledCodeBase`) with proper final relocations etc., by applying fixups and so on. Most changes are here to accomodate those requirements, in particular that `FunctionStencil` should be `Hash`able to be used as a key in the cache: - most source locations are now relative to a base source location in the function, and as such they're encoded as `RelSourceLoc` in the `FunctionStencil`. This required changes so that there's no need to explicitly mark a `SourceLoc` as the base source location, it's automatically detected instead the first time a non-default `SourceLoc` is set. - user-defined external names in the `FunctionStencil` (aka before this patch `ExternalName::User { namespace, index }`) are now references into an external table of `UserExternalNameRef -> UserExternalName`, present in the `FunctionParameters`, and must be explicitly declared using `Function::declare_imported_user_function`. - some refactorings have been made for function names: - `ExternalName` was used as the type for a `Function`'s name; while it thus allowed `ExternalName::Libcall` in this place, this would have been quite confusing to use it there. Instead, a new enum `UserFuncName` is introduced for this name, that's either a user-defined function name (the above `UserExternalName`) or a test case name. - The future of `ExternalName` is likely to become a full reference into the `FunctionParameters`'s mapping, instead of being "either a handle for user-defined external names, or the thing itself for other variants". I'm running out of time to do this, and this is not trivial as it implies touching ISLE which I'm less familiar with. The cache computes a sha256 hash of the `FunctionStencil`, and uses this as the cache key. No equality check (using `PartialEq`) is performed in addition to the hash being the same, as we hope that this is sufficient data to avoid collisions. A basic fuzz target has been introduced that tries to do the bare minimum: - check that a function successfully compiled and cached will be also successfully reloaded from the cache, and returns the exact same function. - check that a trivial modification in the external mapping of `UserExternalNameRef -> UserExternalName` hits the cache, and that other modifications don't hit the cache. - This last check is less efficient and less likely to happen, so probably should be rethought a bit. Thanks to both @alexcrichton and @cfallin for your very useful feedback on Zulip. Some numbers show that for a large wasm module we're using internally, this is a 20% compile-time speedup, because so many `FunctionStencil`s are the same, even within a single module. For a group of modules that have a lot of code in common, we get hit rates up to 70% when they're used together. When a single function changes in a wasm module, every other function is reloaded; that's still slower than I expect (between 10% and 50% of the overall compile time), so there's likely room for improvement.

44d1dee7 - Fix failing cranelift-object tests: make panic message match more generic. (#4211)

Thu, 02 Jun 2022 20:34:10 +0000

Fix failing cranelift-object tests: make panic message match more generic. (#4211)Rust 1.61 changed the way `Debug` output looks for strings with null bytes in them, which broke some expected-panic error message matches. This makes the expectations more generic while still capturing the important part ("has a null byte"). List of files: /wasmtime-44.0.1/cranelift/object/tests/basic.rs

Fix CI for Rust 1.61.0 (#4164)A new version of rustc was released this morning and we have a few small breakages on our CI which need fixing: * A new warning was coming out of the c-api crate about an unneeded `unsafe` block. * The panic message of a task in `cranelift-object` needed updating since the standard library changed how it formats strings with the nul byte.

43a86f14 - Remove more old backend ISA concepts (#3402)

Mon, 04 Oct 2021 08:36:12 +0000

Remove more old backend ISA concepts (#3402)This also paves the way for unifying TargetIsa and MachBackend, since now they map one to one. In theory the two traits could be merged, which would be nice to limit the number of total concepts. Also they have quite different responsibilities, so it might be fine to keep them separate. Interestingly, this PR started as removing RegInfo from the TargetIsa trait since the adapter returned a dummy value there. From the fallout, noticed that all Display implementations didn't needed an ISA anymore (since these were only used to render ISA specific registers). Also the whole family of RegInfo / ValueLoc / RegUnit was exclusively used for the old backend, and these could be removed. Notably, some IR instructions needed to be removed, because they were using RegUnit too: this was the oddball of regfill / regmove / regspill / copy_special, which were IR instructions inserted by the old regalloc. Fare thee well! List of files: /wasmtime-44.0.1/cranelift/object/tests/basic.rs
