+ powerpc-specific genlinearlist
|

|
||||
Revision 1.13 2002/08/11 06:14:40 florian
|
||||
* fixed powerpc compilation problems
|
||||
|
||||
Revision 1.12 2002/08/10 17:15:12 jonas
|

* optimizations and bugfix

Revision 1.11 2002/07/28 09:24:18 carl
|
||||
+ generic case node
|
||||
|
||||
Revision 1.10 2002/07/23 14:31:00 daniel
|
||||
* Added internal error when asked to generate code for 'if expr in []'
|
||||
|
||||
Revision 1.9 2002/07/23 12:34:30 daniel
|
||||
* Readded old set code. To use it define 'oldset'. Activated by default
|
||||
for ppc.
|
||||
|
||||
Revision 1.8 2002/07/22 11:48:04 daniel
|
||||
* Sets are now internally sets.
|
||||
|
||||
Revision 1.7 2002/07/21 16:58:20 jonas
|
||||
* fixed some bugs in tcginnode.pass_2() and optimized the bit test
|
||||
|
||||
Revision 1.6 2002/07/20 11:57:54 florian
|
||||
* types.pas renamed to defbase.pas because D6 contains a types
|
||||
unit so this would conflicts if D6 programms are compiled
|
||||
+ Willamette/SSE2 instructions to assembler added
|
||||
|
||||
Revision 1.5 2002/07/11 14:41:28 florian
|
||||
* start of the new generic parameter handling
|
||||
|
||||
Revision 1.4 2002/07/07 10:16:29 florian
|
||||
* problems with last commit fixed
