TurboFan expects the offset input of a Load or Store node to be a pointer-size input, i.e. an int32 input on 32-bit platforms, and int64 on 64-bit platforms. In WebAssembly we always provided 32-bit offset though, which caused problems when the high word of the register which contained the offset was not empty. With this CL we change the offset input to int64 on 64-bit platforms. In addition we also change the type of the memory_size_ node to int64, so that that we do not have to adjust the type of the memory size at every memory load. This CL will cause performance regressions but is necessary for correctness and to avoid crashes.
