* Support 32-bit build. Signatures/functions/imports/exports etc are defined as varuint32 in the WebAssembly specification so use u32 rather than u64. Decrease the static memory constants for 32-bit addressing mode so that they fit within 32-bit memory constraints. Conditionalize cmake compile of SignalHandlers.cpp so that -m32 is passed when building 32-bit. Add a no-op match for Reloc::X86CallPCRel4 during linking. This is probably the wrong thing, but it allows the tests to pass. Using the same logic from the Reloc::X86PCRel4 case did not work.
This is the wasmtime-runtime crate, which contains wasm runtime library
support, supporting the wasm ABI used by wasmtime-environ,
wasmtime-jit, and wasmtime-obj.
This crate does not make a host vs. target distinction; it is meant to be compiled for the target.
