Hi All,
I am doing a port of GCC for a small internal processor and I have a question about function parameter passing. I am allocating space for function parameters on the frame (via crtl->outgoing_args_size) and want gcc to use this space via frame pointer manipulation, not stack pointer manipulation. So far, I cannot get gcc to use the frame pointer for the args, it manipulates the stack pointer directly (this is a problem since the stack pointer is not directly accessible). I have the following configurations set: #define ACCUMULATE_OUTGOING_ARGS (1) #define REG_PARM_STACK_SPACE(x) (0) //NOT USED #define INCOMING_REG_PARM_STACK_SPACE #define OUTGOING_REG_PARM_STACK_SPACE(x) (1) #define STACK_PARMS_IN_REG_PARM_AREA (1) but these do not seem to help. The compiler uses the frame pointer correctly for all the local variables, so I know it is aware of it. Any suggestions are appreciated. Steve (Broadcom)
