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.
This makes several changes:
- It adds an index_type to heap declarations, allowing heaps to specify the
type for indexing. This also anticipates 64-bit heap support.
- It adds a memory_type to deref global values, allowing deref globals to
have types other than pointers. This is used to allow the bound variable
in dynamic heaps to have type i32, to match the index type in heaps
with i32 index type.
- And, it fixes heap legalization to do the bounds check in the heap's
index type.
* fix error not reported if at least one other error expected.
* Fixed unused extern crate error if wasm feature is not enabled.
* No longer reporting deref cycles multiple times.
* Fix filetest type_check.clif.
* Switched comparison order for perf.
* Fixed isa/riscv/verify-encoding.clif filetest.
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.
* Fixed error reporting.
* Fixed compile time error when wasm feature is disabled.
* Fixed valid instructions not being printed in print_function_error.
* Fixed errors print_function_error not writing valid instructions after end.
* Made multiple checks non-fatal.
* verify_global_values is no longer fatal.
* Slightly better formatting of errors in pretty_verifier_error.
Allows for host programs to directly expose symbols to jitted code without
needing to deal with platform-specific linker arguments, or dynamic
dispatch.
* clippy: Allow subsec_nanos usage for now.
The recommendation from clippy requires Rust 1.27, but we currently
support Rust 1.25 and later.
* Simplify ref pattern matches.
This was recommended by clippy.
