d03841dc16 * store register para's to memory before copying the valuepara's, because 
that one requires them to be there already (and it calls subroutines ->
    could overwrite those registers)

56132c1a9c * assembler procedures now again get a stackframe if they have local 
variables. No space is reserved for a function result however.
    Also, the register parameters aren't automatically saved on the stack
    anymore in assembler procedures.

a15d8cfe39 * a_load_reg_reg() now has two size parameters: source and dest. This 
allows some optimizations on architectures that don't encode the
    register size in the register name.

f77536fece * use index register when available for generating a reference with 
only a signle register. Using the base register could possibly
    destroy the framepointer
 2002-09-01 19:27:34 +00:00
peter
5a06f334b7 * fixed maybe_save that did not support a reference with only

peter
a28f75ed03 * sym.insert_in_data removed 
* symtable.insertvardata/insertconstdata added
  * removed insert_in_data call from symtable.insert, it needs to be

    directives are parsed. This fixes the cdecl parast problem
  * push_addr_param has an extra argument that specifies if cdecl is used
    or not

peter
ac71268ce6 * saving of asmsymbols in ppu supported 
* asmsymbollist global is removed and moved into a new class
    tasmlibrarydata that will hold the info of a .a file which
    corresponds with a single module. Added librarydata to tmodule
    to keep the library info stored for the module. In the future the
    objectfiles will also be stored to the tasmlibrarydata class
  * all getlabel/newasmsymbol and friends are moved to the new class
 2002-08-11 13:24:10 +00:00
carl
947142291c * stack allocation is now done separately (at the end) of genentrycode
