# Add some glues between recompiler block | |||
==== DispatcherReg ==== | |||
* Generated by '''_DynGen_DispatcherReg''' | |||
* High-Level Description | |||
# Compute the address of BASEBLOCK related to the current PC. It is equivalent to "'''bb = PC_GETBLOCK(cpuRegs.pc)'''" | |||
# Jump to the related function pointer. It is equivalent to "'''bb->m_pFnptr()'''" | |||
