Revision 1.11 2003-04-28 09:49:58 mazen
- InternalError removed from TSparcCallNode.push_framepointer as it is called by common coplier code.
Revision 1.10 2003/04/27 11:21:36 peter
* aktprocdef renamed to current_procdef
* procinfo renamed to current_procinfo
* procinfo will now be stored in current_module so it can be
cleaned up properly
* gen_main_procsym changed to create_main_proc and release_main_proc
to also generate a tprocinfo structure
* fixed unit implicit initfinal
Revision 1.9 2003/04/04 15:38:56 peter
* moved generic code from n386cal to ncgcal, i386 now also
uses the generic ncgcal
Revision 1.8 2003/02/05 22:44:55 mazen
* making UNIT lower case.
Revision 1.7 2003/02/04 21:50:54 mazen
* fixing internal errors related to notn when compiling RTL
Revision 1.6 2003/01/22 22:30:03 mazen
- internal errors rmoved from a_loar_reg_reg when reg sizes differs from 32
Revision 1.5 2002/11/14 21:42:08 mazen
* fixing return value variable address
Revision 1.4 2002/10/10 19:57:52 mazen
* Just to update repsitory
Revision 1.3 2002/09/30 19:12:14 mazen
* function prologue fixed
Revision 1.2 2002/08/30 13:16:23 mazen
*call parameter handling is now based on the new param manager
Revision 1.2 2002/08/17 09:23:49 florian
* first part of procinfo rewrite
Revision 1.1 2002/08/13 21:40:59 florian
* more fixes for ppc calling conventions
