In cranelift x86 encodings, it seemed unintuitive to specialize Templates with both `infer_rex()`` and `w()`: if `w()` is specified, the REX.W bit must be set so a REX prefix is alway required--no need to infer it. This change forces us to write `rex().w()``--it's more explicit and shows more clearly what cranelift will emit. This change also modifies the tests that expected DynRex recipes.
Previously `test rodata` would cause failures when compiling Cranelift IR that had assertions about the current sink offset (e.g. multiple blocks, see `emit_function` in `binemit/mod.rs`).
- Convert recipes to have necessary size calculator
- Add a missing binemit function, `put_dynrexmp3`
- Modify the meta-encodings of x86 SIMD instructions to use `infer_rex()`, mostly through the `enc_both_inferred()` helper
- Fix up tests that previously always emitted a REX prefix
Removes an edge towards the `synstructure` dependency in our dependency
graph which, if removed entirely, is hoped to reduce build times locally
and on CI as you switch between `cargo build` and `cargo test` because
deep dependencies like `syn` won't have their features alternating back
and forth.
Until #1306 is resolved (some spilling/regalloc issue with larger FPR register banks), this removes FPR32 support. Only Wasm's `i64x2.mul` was using this register class and that instruction is predicated on AVX512 support; for the time being, that instruction will have to make do with the 16 FPR registers.
This patch updates or removes all references to the Cranelift repository. It affects links in README documents, issues that were transferred to the Wasmtime repository, CI badges, and a small bunch of sundry items.
Update the documentation for the merger, and also for various changes in
Cranelift. Remove some old obsolete documentation, and convert the remaining
Sphinx files to Markdown. Some of the remaining content is still out of
date, but this is a step forward.
* Manually rename BasicBlock to BlockPredecessor
BasicBlock is a pair of (Ebb, Inst) that is used to represent the
basic block subcomponent of an Ebb that is a predecessor to an Ebb.
Eventually we will be able to remove this struct, but for now it
makes sense to give it a non-conflicting name so that we can start
to transition Ebb to represent a basic block.
I have not updated any comments that refer to BasicBlock, as
eventually we will remove BlockPredecessor and replace with Block,
which is a basic block, so the comments will become correct.
* Manually rename SSABuilder block types to avoid conflict
SSABuilder has its own Block and BlockData types. These along with
associated identifier will cause conflicts in a later commit, so
they are renamed to be more verbose here.
* Automatically rename 'Ebb' to 'Block' in *.rs
* Automatically rename 'EBB' to 'block' in *.rs
* Automatically rename 'ebb' to 'block' in *.rs
* Automatically rename 'extended basic block' to 'basic block' in *.rs
* Automatically rename 'an basic block' to 'a basic block' in *.rs
* Manually update comment for `Block`
`Block`'s wikipedia article required an update.
* Automatically rename 'an `Block`' to 'a `Block`' in *.rs
* Automatically rename 'extended_basic_block' to 'basic_block' in *.rs
* Automatically rename 'ebb' to 'block' in *.clif
* Manually rename clif constant that contains 'ebb' as substring to avoid conflict
* Automatically rename filecheck uses of 'EBB' to 'BB'
'regex: EBB' -> 'regex: BB'
'$EBB' -> '$BB'
* Automatically rename 'EBB' 'Ebb' to 'block' in *.clif
* Automatically rename 'an block' to 'a block' in *.clif
* Fix broken testcase when function name length increases
Test function names are limited to 16 characters. This causes
the new longer name to be truncated and fail a filecheck test. An
outdated comment was also fixed.
* All: Drop 'basic-blocks' feature
This makes it so that 'basic-blocks' cannot be disabled and we can
start assuming it everywhere.
* Tests: Replace non-bb filetests with bb version
* Tests: Adapt solver-fixedconflict filetests to use basic blocks
This commit adds a basic test for reference types on 32/64bit systems.
* Storing a ref type in a table
* Loading a ref type from a table
* Passing ref types to a function
* Returning ref types from a function
* `is_null` instruction
* `is_invalid` instruction
This commit aligns the representation of stackmaps to be the same
as Spidermonkey's by:
* Reversing the order of the bitmap from low addresses to high addresses
* Including incoming stack arguments
* Excluding outgoing stack arguments
Additionally, some accessor functions were added to allow Spidermonkey
to access the internals of the bitmap.
This is a breaking API change: the following settings have been renamed:
- jump_tables_enabled -> enable_jump_tables
- colocated_libcalls -> use_colocated_libcalls
- probestack_enabled -> enable_probestack
- allones_funcaddrs -> emit_all_ones_funcaddrs
The Intel manual uses `CMPNLT` and `CMPNLE` to denote not-less-than and not-less-than-or-equals. These were translated previously to `FloatCC::GreaterThan` and `FloatCC::GreaterThanOrEqual` but should be correctly translated to `FloatCC::UnorderedOrGreaterThanOrEqual` and `FloatCC::UnorderedOrGreaterThan`. This change adds the necessary legalizations to make use of these new encodings.
This patch adds a third mode for templates: REX inference is requestable
at template instantiation time. This reduces the number of recipes
by removing rex()/nonrex() redundancy for many instructions.
