Revision 1.6 2002-09-06 16:58:43 jonas
* fixed wrong references (used r0 as base register)
Revision 1.5 2002/08/10 17:14:36 jonas
* various fixes, mostly changing the names of the modifies registers to
upper case since that seems to be required by the compiler
Revision 1.4 2001/09/27 15:30:29 jonas
* conversion to compilerproc and to structure used by i386 rtl
* some bugfixes
* powerpc.inc is almost complete (only fillchar/word/dword, get_frame etc
and the class helpers are still needed
- removed unnecessary register saving in set.inc (thanks to compilerproc)
* use registers reserved for parameters as much as possible instead of
those reserved for local vars (since those have to be saved by the
called anyway, while the ones for local vars have to be saved by the
callee)
Revision 1.3 2001/07/07 12:46:12 jonas
* some small bugfixes and cache optimizations
Revision 1.2 2001/02/11 12:15:03 jonas
* some small optimizations and bugfixes
Revision 1.1 2001/02/10 16:10:32 jonas
* initial implementation: everything implemented, nothing tested
