174cea8023 * changed calling of external procedures to be the same as under gcc 
(don't worry about all the generated stubs, they're optimized away
     by the linker)
    -> side effect: no need anymore to use special declarations for
       external C functions under Darwin compared to other platforms
       (it's still necessary for variables though)

    be reused before some point

Jonas Maebe
4f8c390198 * fixed regvars so they work with newra (at least for ppc) 
* fixed some volatile register bugs
  + -dnotranslation option for -dnewra, which causes the registers not to
    be translated from virtual to normal registers. Requires support in
    the assembler writer as well, which is only implemented in aggas/
    agppcgas currently
 2003-08-17 16:59:20 +00:00

a3cb0d2002 * don't use rg.getregisterint() anymore in g_stackframe_entry_*, because 
the register colouring has already occurred then, use a hard-coded
    register instead
 2003-07-23 11:02:23 +00:00
Jonas Maebe
d73acd12f6 * fixed newra bug due to the fact that we sometimes need a temp reg 
when loading/storing to memory (base+index+offset is not possible)
    and because a reference is often freed before it is last used, this
    temp register was soemtimes the same as one of the reference regs
 2003-07-20 20:39:20 +00:00

Jonas Maebe
c70f75f1b7 * compile with -dppc603 to not use unaligned float loads in move() and 
g_concatcopy, because the 603 and 604 take an exception for those
    (and netbsd doesn't even handle those in the kernel). There are
    still some of those left that could cause problems though (e.g.
    in the set helpers)
 2003-05-29 21:17:27 +00:00
