630be7733d Add llvm 'readonly' attribute to calls of the memory size function. 
In passing, delete a lot of dead code. Remove old VM intrinsics for memory.size, memory.grow and breakpoints.

4d791d3e55 Rename mem_buf_slice to contents. 
The callers are slicing a memory buffer, but that's not relevant to this function's API.

c02cd76623 Refactor trampoline generation to use load_object_file. 2020-05-21 13:53:48 -07:00
Nick Lewycky
3764e7b9f8 Change load_object_file to take a RelocationTarget instead of a LocalFunctionIndex. 
This removes its last connection to the implementation details of having a wasm_module, which we don't want to have to rely on when building trampolines.

There currently isn't a RelocationTarget for a trampoline function that refers to itself (none of been observed to done so yet), so we make the RelocationTarget optional.

02f7e58c01 Change load_object_file to take a callback that converts symbol names into relocation targets. 
This change means that load_object_file no longer needs a ModuleInfo, which trampoline generation doesn't have.

ae6f0dadb2 Stop naming instructions with numbered names. 
LLVM will number instructions if you don't provide a name, so we get %7 instead of %s7 from calling state.var_name(). LLVM doesn't assign the numbers until printing out the LLVM IR as text, which we never do in a normal run of wasmer.

If you're editing a .ll text by hand and you're worried about messing up the numbering, use `opt --instnamer` to assign autogenerated names to all numbered instructions.

Cache lookup of VMMemoryDefinition.

0df99b5dbc Cache lookup of VMMemoryDefinition. 
To add to the cache, mutability is required, so now `resolve_memory_ptr` must be `&mut self` which means that `translate_operator` may not hold those convenient immutable references across the whole function.

The search and replace to implement the above changes affected some commented out code, that code is removed.

MemoryStyle grows PartialEq and Eq so that we can check what the memory style is without a match expression.
