Dear sirs,
When trying to generate code debuggable by GDB, I meet a problem:
* it seems mips C code will expect a frame pointer = sp after stack
adjustment
* but in cpupara.pas, when we create para info, we don't know yet the
whole stack size, thus the reference offset cannot be set correctly

The following code compiles both with :

Dear sirs,
C code is something like:
addiu sp,sp,-LocalSize
swfp, 4(sp)
move fp, sp
in this way, I don't know how to generate parameter references since no
usable base register to get fixed offset for parameters in
create_paraloc_info_intern.
Can we use a special virtual
