Hi, everybody! Although SDCC manual contains some information about stm8 options it has no information on working register set and procedure calling convention.
Can anyone explain: what registers are used and for what purpose? What are function call prologues and epilogues like? What about interrupt ? How parameters and return values are placed in registers/stack? What is the difference between medium and large memory models with regard to previous questions? Best regards, Paul Beltyukov
