+ Revision 1.1 2002/08/10 14:47:50 carl
|
|
|
+ + moved target_cpu_string to cpuinfo
|
|
|
+ * renamed asmmode enum.
|
|
|
+ * assembler reader has now less ifdef's
|
|
|

|
|
|
+
|
|
|
+ Revision 1.21 2002/07/20 11:58:05 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 1.15 2002/05/12 16:53:18 peter
|
|
|
+ * moved entry and exitcode to ncgutil and cgobj
|
|
|
+ * foreach gets extra argument for passing local data to the
|
|
|
+ iterator function
|
|
|
+ * -CR checks also class typecasts at runtime by changing them
|
|
|
+ into as
|
|
|
+ * fixed compiler to cycle with the -CR option
|
|
|
+ * fixed stabs with elf writer, finally the global variables can
|
|
|
+ be watched
|
|
|
+ * removed a lot of routines from cga unit and replaced them by
|
|
|
+ calls to cgobj
|
|
|
+ * u32bit-s32bit updates for and,or,xor nodes. When one element is
|
|
|
+ u32bit then the other is typecasted also to u32bit without giving
|
|
|
+ a rangecheck warning/error.
|
|
|
+ * fixed pascal calling method with reversing also the high tree in
|
|
|
+ the parast, detected by tcalcst3 test
|
