Revision 1.12 2002-09-07 20:57:08 carl
|
|
* cardinal -> longword
|
|
|
|
Revision 1.11 2002/09/07 15:25:14 peter
|
|
* old logs removed and tabs fixed
|
|
|
|
Revision 1.10 2002/08/15 15:15:55 carl
|
|
* jmpbuf size allocation for exceptions is now cpu specific (as it should)
|
|
* more generic nodes for maths
|
|
* several fixes for better m68k support
|
|
|
|
Revision 1.9 2002/08/12 15:08:44 carl
|
|
+ stab register indexes for powerpc (moved from gdb to cpubase)
|
|
+ tprocessor enumeration moved to cpuinfo
|
|
+ linker in target_info is now a class
|
|
* many many updates for m68k (will soon start to compile)
|
|
- removed some ifdef or correct them for correct cpu
|
|
|
|
Revision 1.8 2002/08/10 14:52:52 carl
|
|
+ moved target_cpu_string to cpuinfo
|
|
* renamed asmmode enum.
|
|
* assembler reader has now less ifdef's
|
|
* move from nppcmem.pas -> ncgmem.pas vec. node.
|
|
|
|
Revision 1.7 2002/05/18 13:34:26 peter
|
|
* readded missing revisions
|
|
|
|
Revision 1.6 2002/05/16 19:46:53 carl
|
|
+ defines.inc -> fpcdefs.inc to avoid conflicts if compiling by hand
|
|
+ try to fix temp allocation (still in ifdef)
|
|
+ generic constructor calls
|
|
+ start of tassembler / tmodulebase class cleanup
|
|
|
|
Revision 1.4 2002/05/13 19:52:46 peter
|
|
* a ppcppc can be build again
|
|
|
|
Revision 1.3 2002/04/07 13:43:11 carl
|
|
- moved type constant
|
|
|
|
