* Add encodings for i8 and i16 copy, spill, fill, ireduce.i8.i16
Also adds legalization for srem, irsub_imm, {u,s}extend.i16.i8
Fixes#477 cc #466
* Legalize popcnt, clz and ctz for i8 and i16
* Fix bug in call_memset
* Add 'jump_table_entry' and 'indirect_jump' instructions.
* Update CodeSink to keep track of code size. Pretty up clif-util's disassembly output.
* Only disassemble the machine portion of output. Pretty print the read-only data after it.
* Update switch frontend code to use new br_table instruction w/ default.
The majority of the test modules were already named "tests", and that's
what the example in the Rust book uses, so switch to that for all test
modules, for consistency.
* 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.
* Add more content to cranelift-entity's README.md.
Summarize what cranelift-entity provides, and how it differs from
similar systems such as slotmap, which was recently highlighted in the
RustConf 2018 Closing Keynote.
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"
