* Remove `Module`'s `finalize_function` and `finalize_data`.
Remove the ability to finalize individiual functions and data objects,
and instead just provide a way to finalize everything that's been
defined but not yet finalized. This allows SimpleJIT to share an
allocation between multiple functions without having to worry about
individual functions being finalized and needing to be published
without the other functions in the same allocation.
Users of the return values of `Module`'s `finalize_function` and
`finalize_data` should now use `get_finalized_function` and
`get_finalized_data` to obtain these values.
When an object being finalized references an object declared as needing
a definition, the definition needs to be available. Add asserts to catch
this specific case.
* Reorganize the global value kinds.
This:
- renames "deref" global values to "load" and gives it a offset that works
like the "load" instructions' does
- adds an explicit "iadd_imm" global value kind, which replaces the
builtin iadd in "vmctx" and "deref" global values.
- also renames "globalsym" to "symbol"
Add `publish()` function to cranelift-module's `Backend` trait, which
allows `finalize_all()` to defer making memory executable until it
has finished all of the patching it needs to do.
It was redundant, as data object declarations also have a writable
field, so just use that, avoiding the need for users to declare the
same thing twice.
Fixes#456.
The individual crates are published separately from the main repository
on crates.io. To ensure that a copy of the LICENSE file accompanies all
published copies of the code, give each crate its own LICENSE file.
Make cretonne-codegen's `result` module private, and instead just export
`CodegenError` and `CodegenResult` at the top level of the
cretonne-codegen crate. This makes them more consistent with Result and
Error types in other cretonne crates.
