* Add ARMv7 as CI test target
* Avoid UB in conversions from floating point
When truncating floating point values to integer values, we need to
avoid undefined behavior if the argument does not fit into the target
type which is currently impossible using casts of primitive types.
Hence, this reimplements those conversions using arbitrary precision
integers and rationals from the num crate.
* Remove hashbrown and use BTree{Map,Set} from the alloc crate
wasmi-validation must handle untrusted input and hence we switch from
Hash{Set,Map} (whether std's or hashbrown's) to BTree{Set,Map} to avoid
algorithmic complexity attacks while retaining no_std support.
Closes#183
* Improve memory locality of checking for duplicate exports
Using a sorted slice gives us the same O(N log N) worst case execution
time as using a BTreeMap, but using a single allocation as with HashMap,
so that we should see better memory locality and hence better constant
factors when checking for duplicate exports.
* Add some docs.
* return_type isn't failable
* Add comment about safety of top_label
* Attempt number 10
* Rework.
Now we will a compiler which wraps and uses info from a evaluation simulator.
* Get rid of outcome
* Introduce StartedWith
* Actually use started_with.
* Mirror label_stack.
* Avoid using frame_type.
* Finally get rid from frame_type.
* Extract compilation
* Refactoring cleaning
* Validation separated from compilation.
* Move sink to FunctionReader
* Rename to compiler.
* fmt
* Move push_label under validation context.
* Add Validation traits
* Express the compiler using validation trait
* Move code under prepare
* Comments.
* WIP
* The great move of validation
* Make validation compile
* Make it compile.
* Format it.
* Fix warnings.
* Clean.
* Make it work under no_std
* Move deny_floating_point to wasmi
* Rename validate_module2 → validate_module
* Make validation tests work
* Make wasmi compilation tests work
* Renamings.
* Get rid of memory_units dependency in validation
* Rename.
* Clean.
* Estimate capacity.
* fmt.
* Clean and detail End opcode.
* Add comment about top_label safety
* Remove another TODO
* Comment access to require_target
* Remove redundant PartialEq
* Print value that can't be coerced to u32
* s/with_instruction_capacity/with_capacity
* fmt.
* fmt
* Proofs
* Add better proof
* Get rid of unreachable in StackValueType
* Propagate error if frame stack overflown on create
* use checked sub instead of -
* Keep::count
* add default-enabled std feature
* use parity-wasm/std feature only if std is enabled
* drop dependency on std::io
* use hashmap_core instead of std::collections::HashMap
* disable std::error in no_std
* core and alloc all the things
* mention no_std in readme
* add no_std feature and use hashmap_core only on no_std
* rename the no_std feature to core
* drop dependency on byteorder/std
* simplify float impl macro
* remove some trailing whitespace
* use libm for float math in no_std
* add note about no_std panics of libm to readme
* Embed nan-preserving-float crate.
* Add no_std check to the Travis CI config
* add missing dev-dependency
Move all spec testsuite into `/tests` directory.
So it means that several changes will happen:
- Compilation will share common dependencies in target directory. This should make CI builds faster. This also should reduce space requirements.
- Common Cargo.lock file
- `cargo test` will include spec tests.
- `cargo check --tests` will also include spec tests.
* Initial implementation
* Not use grow as it is makes debug builds very slow
* Use Pages::BYTE_SIZE for LINEAR_MEMORY_PAGE_SIZE
* Tidy docs.
* Use memory_units from git.
