Major API-incompatible changes include:
- Introduce TrapCode::UnreachableCodeReached, used for unreachable in wasm.
- cranelift-wasm's `declare_signature` now takes its signature by value
- cranelift-wasm's `declare_table_elements` `elems` parameter now takes a boxed slice
- Remove cranelift-wasm's `ModuleEnvironment`'s `get_signature`,
`get_num_func_imports`, `get_func_type`, and `get_global`.
With Rust 2018 Edition, the `mod std` trick to alias `core` names to
`std` no longer works, so switch to just having the code use `core`
explicitly.
So instead, switch to just using `core::*` for things that in core.
This is more consistent with other Rust no_std code. And it allows
us to enable `no_std` mode unconditionally in the crates that support
it, which makes testing a little easier.
There actually three cases:
- For things in std and also in core, like `cmp`: Just use them via
`core::*`.
- For things in std and also in alloc, like `Vec`: Import alloc as std, as
use them from std. This allows them to work on both stable (which
doesn't provide alloc, but we don't support no_std mode anyway) and
nightly.
- For HashMap and similar which are not in core or alloc, import them in
the top-level lib.rs files from either std or the third-party hashmap_core
crate, and then have the code use super::hashmap_core.
Also, no_std support continues to be "best effort" at this time and not
something most people need to be testing.
* initial cargo fix run
* Upgrade cranelift-entity crate
* Upgrade bforest crate
* Upgrade the codegen crate
* Upgrade the faerie crate
* Upgrade the filetests crate
* Upgrade the codegen-meta crate
* Upgrade the frontend crate
* Upgrade the cranelift-module crate
* Upgrade the cranelift-native crate
* Upgrade the cranelift-preopt crate
* Upgrade the cranelift-reader crate
* Upgrade the cranelift-serde crate
* Upgrade the cranelift-simplejit crate
* Upgrade the cranelift or cranelift-umbrella crate
* Upgrade the cranelift-wasm crate
* Upgrade cranelift-tools crate
* Use new import style on remaining files
* run format-all.sh
* run test-all.sh, update Readme and travis ci configuration
fixed an AssertionError also
* Remove deprecated functions
* test-no_std: use cargo +nightly
assume folks have rustup set to use stable by default
* cretonne-module, -faerie, -simplejit: use new ModuleError enum
CtonError is not really appropriate for use in the module system.
Instead, create a new enum ModuleError, which implements failure::Fail
(works with no_std). Translate existing panics and unimplemented
error cases to return ModuleErrors.
* cretonne-faerie: export FaerieProduct
* cretonne-module: expose FuncOrDataId, and Module::get_name to lookup
This is helpful for looking up a name that has already been declared.
Also, implement FuncOrDataId -> ExternalName conversion.
* cretonne-faerie: depend on faerie 0.3.0
which has bugfix for data relocations
* cretonne-module: change InvalidDefinition to InvalidImportDefinition
per dan's code review. plus another typo fix
* cretonne-faerie: add optional manifest of all traps from codegen
* cretonne-module: provide more context in panics
* cretonne-faerie: updates to docs
* cretonne-faerie: return an Err instead of debug_assert when isa not pic
* Initial skeleton.
* Add basic faerie support.
This adds enough functionality to enable simple .o file writing through
faerie. This included adding the functionality to Module to support
RelocSink implementations.
* Add basic SimpleJIT support.
This adds enough functionality to enable a simple program to be jitted
and executed.
* Make declare_func_in_func take a Function instead of a Context.
It only needs the Function, and sometimes it's useful to call it from
places that don't have a full Context.
* Temporarily disable local and exported global variables in the Faerie backend.
Faerie assumes these variables use pc-relative offset instructions, and
Cretonne is not yet emitting those instructions.
* FaerieBackend depends on PIC.
Faerie itself only supports PIC objects for now, so add an assert to
Cretonne to check that it's using a PIC target flag.
* SimpleJIT support for data objects.
* Preliminary faerie support for data objects.
* Support for data objects in faerie using the new colocated flag.
* Unit tests for DataContext and friends.
* Add a Module::consume() function.
This consumes the Module and returns the contained Backend, so that
users can call Backend-specific functions with it. For example, the
Faerie backend has functions to write an object file.
* Update the new crates to version 0.4.4.
* Make FaerieBackend own its TargetIsa.
This simplifies its interface, as it eliminates a lifetime parameter.
While we may eventually want to look into allowing multiple clients to
share a TargetIsa, it isn't worth the complexity for FaerieBackend
right now.
* Don't try to protect faerie from multiple declarations.
Let faerie decide for itself whether it wants to consider two
declarations to be compatible.
* Use debug_assert_eq rather than debug_assert with ==.
* Fix FaerieRelocSink's reloc_external to handle data object names.
* Relax the asserts in get_function_definition and get_data_definition.
These functions don't require definable symbols, but they do require
that definable symbols be defined. This is needed for the simplejit
backend.
* Add a function to the faerie backend to retrieve the artifact name.
* Sync up with cretonne changes.
