74355b0b03 NFC. Move looking up a function in the same wasm module to CtxType. 
This is a straight refactor, this doesn't add caching yet.

7a1ac7b843 Don't mark loads and stores volatile when they're bounds checked at runtime. 2020-05-26 14:57:11 -07:00
Nick Lewycky
3d654d2c25 Add function that marks loads/store volatile. Static/dynamic condition is TODO. 
Now that we apply three annotations to every user memory access, factor it out into a new function to apply them.

We do this for the load and stores, but not yet the atomicrmw's.

630be7733d Add llvm 'readonly' attribute to calls of the memory size function.

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.
