* 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-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
