* Update to rustfmt-preview.
* Run "cargo fmt --all" with rustfmt 0.4.1.
rustfmt 0.4.1 is the latest release of rustfmt-preview available on the
stable channel.
* Fix a long line that rustfmt 0.4.1 can't handle.
* Remove unneeded commas left behind by rustfmt.
* 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
This eliminates API confusion and surface area with respect to what state
the `Backend` needs to be in at different points.
Now, API users will construct a `Builder`, and pass it into the `Module`
which uses it to constrct a `Backend`. The `Backend` instance only lives
inside the `Module`. And when finished, the `Module` can return a
`Product` back to the user providing any outputs it has.
* 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.
