# 1.1: Register definitions
# -------------------------

# IPInt uses a number of core registers which store the interpreter's state:
# - PC: (Program Counter) IPInt's program counter. This records the interpreter's position in Wasm bytecode.
# - MC: (Metadata Counter) IPInt's metadata pointer. This records the corresponding position in generated metadata.
# - WI: (Wasm Instance) pointer to the current JSWebAssemblyInstance object. This is used for accessing
#       function-specific data.
# - PL: (Pointer to Locals) pointer to the address of local 0 in the current function. This is used for accessing
#       locals quickly.
# - MB: (Memory Base) pointer to the current Wasm memory base address.
# - BC: (Bounds Check) the size of the current Wasm memory region, for bounds checking.
#
# Additionally, there are a few registers that are optionally supported for optimization:
# - IB: (Instruction Base) pointer to the address of the `unreachable` (0x00) label, removing the need to reload
#       this address at every dispatch.
# - HR: (Hoist Register) used for hoisting the load of the next opcode in Wasm instructions with low register
#       pressure, helping reduce the impact of load misses.
#
# Finally, we provide four "sc" (safe for call) registers which are guaranteed to not overlap with argument
# registers (sc0, sc1, sc2, sc3)
