In my specific case I am passing "&p1, &p2, ..." deliberately. I will try removing the "&" operator and see what is generated...
OK, tried that and without a "&" operator the generated code passes the address of a COPY of the value of the variable. So, the parameter list is addresses, but NOT the address of the actual variable, only a COPY of the value, at least for scalar variables. String parameters (char *) specifically declared in the function declaration are passed the actual variable address. Don't know yet how "struct" or "union" parameters will be passed, still experimenting with those. The manuals really ought to make these rules clearer. I need to RTFM in the C/C++ language reference manual again to see if I can find a better description of what should be generated in each case.

Does this pragma imply that parameters are passed by reference? I hope so. Because, if not, the last by value parm will get the first bit set, which changes its value.
