This commit is intended to update wasmparser to 0.59.0. This primarily
includes bytecodealliance/wasm-tools#40 which is a large update to how
parsing and validation works. The impact on Wasmtime is pretty small at
this time, but over time I'd like to refactor the internals here to lean
more heavily on that upstream wasmparser refactoring.
For now, though, the intention is to get on the train of wasmparser's
latest `main` branch to ensure we get bug fixes and such.
As part of this update a few other crates and such were updated. This is
primarily to handle the new encoding of `ref.is_null` where the type is
not part of the instruction encoding any more.
- Create the ELF image from Compilation
- Create CodeMemory from the ELF image
- Link using ELF image
- Remove creation of GDB JIT images from crates/debug
- Move make_trampoline from compiler.rs
This somewhat cuts down on duplicate dependencies. `wast` is used in a much older version (`11.0.0`) by `witx`, and can be updated without issues there as well, but this at least gets us from 3 copies to 2.
* Refactor how relocs are stored and handled
* refactor CompiledModule::instantiate and link_module
* Refactor DWARF creation: split generation and serialization
* Separate DWARF data transform from instantiation
* rm LinkContext
There was a bug how value labels were resolved, which caused some DWARF expressions not be transformed, e.g. those are in the registers.
* Implements FIXME in expression.rs
* Move TargetIsa from CompiledExpression structure
* Fix expression format for GDB
* Add tests for parsing
* Proper logic in ValueLabelRangesBuilder::process_label
* Tests for ValueLabelRangesBuilder
* Refactor build_with_locals to return Iterator instead of Vec<_>
* Misc comments and magical numbers
Support a few DWARF-5 only features:
* read .debug_addr
* read .debug_rnglists
* read .debug_loclists when present
* add dwarf-5 test
* read .debug_addr
* read .debug_rnglists
* read .debug_loclists when present
* support .debug_line_str and .debug_str_offsets

This commit makes the following changes to unwind information generation in
Cranelift:
* Remove frame layout change implementation in favor of processing the prologue
and epilogue instructions when unwind information is requested. This also
means this work is no longer performed for Windows, which didn't utilize it.
It also helps simplify the prologue and epilogue generation code.
* Remove the unwind sink implementation that required each unwind information
to be represented in final form. For FDEs, this meant writing a
complete frame table per function, which wastes 20 bytes or so for each
function with duplicate CIEs. This also enables Cranelift users to collect the
unwind information and write it as a single frame table.
* For System V calling convention, the unwind information is no longer stored
in code memory (it's only a requirement for Windows ABI to do so). This allows
for more compact code memory for modules with a lot of functions.
* Deletes some duplicate code relating to frame table generation. Users can
now simply use gimli to create a frame table from each function's unwind
information.
Fixes#1181.
This exposes the functionality of `fde::map_reg` on the `TargetIsa` trait, avoiding compilation errors on architectures where register mapping is not yet supported. The change is conditially compiled under the `unwind` feature.
* Wasmtime 0.15.0 and Cranelift 0.62.0. (#1398)
* Bump more ad-hoc versions.
* Add build.rs to wasi-common's Cargo.toml.
* Update the env var name in more places.
* Remove a redundant echo.
Both cranelift-codegen and wasmtime-debug need to map Cranelift registers to Gimli registers. Previously both crates had an almost-identical `map_reg` implementation. This change:
- removes the wasmtime-debug implementation
- improves the cranelift-codegen implementation with custom errors
- exposes map_reg in `cranelift_codegen::isa::fde::map_reg` and subsequently `wasmtime_environ::isa::fde::map_reg`
* Bump Wasmtime to 0.14.0.
* Update the publish script for the wiggle crate wiggle.
* More fixes.
* Fix lightbeam depenency version.
* cargo update
* Cargo update wasi-tests too.
And add cargo update to the version-bump scripts.
The crates/debug/src/transform/address_transform.rs is unoptimized in terms of data structures. This PR refactors this file to remove creation of intermediate in-heap structures, thus improves overall performance of the DWARF transformation.
* Reduce amount of memory allocated in translate_ranges_raw
* refactor translate_ranges
* Don't transform non-unit .debug_line
* type annotation for TransformRangeXXXIter's
* Fix empty generated wasm positions
* Cargo.lock: Update, to no longer use multiple versions of autocfg
* Update wasmtime-debug and wasmtime-profiling to current gimli 0.20.0
This also eliminates duplicate versions of gimli and arrayvec, and
eliminates the nodrop dependency entirely.
* Update wasmtime-profiling to goblin 0.1.3 and object 0.17.0
This also eliminates two duplicate versions of goblin, and duplicate
versions of proc-macro2, quote, syn, scroll_derive, and unicode-xid.
* Update wasmtime-profiling to current scroll 0.10.1
This eliminates duplicate versions of scroll.
* Update wasmtime-profiling to current target-lexicon 0.10.0
This eliminates duplicate versions of target-lexicon.
* Update wasmtime-interface-types to current walrus and wasm-webidl-bindings
This also eliminates the oldest of the three duplicate versions of
wasmparser.
* Update wasmtime-wast to current wast 8.0.0
This eliminates one of the duplicate versions of wast.
