Revision 1.26 2002/05/18 13:34:16 peter
|
|
* readded missing revisions
|
|
|
|
Revision 1.25 2002/05/16 19:46:44 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 1.23 2002/05/12 16:53:09 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
|
|
|
|
Revision 1.22 2002/01/24 12:33:53 jonas
|
|
* adapted ranges of native types to int64 (e.g. high cardinal is no
|
|
longer longint($ffffffff), but just $fffffff in psystem)
|
|
* small additional fix in 64bit rangecheck code generation for 32 bit
|
|
processors
|
|
* adaption of ranges required the matching talgorithm used for selecting
|
|
which overloaded procedure to call to be adapted. It should now always
|
|
select the closest match for ordinal parameters.
|
|
+ inttostr(qword) in sysstr.inc/sysstrh.inc
|
|
+ abs(int64), sqr(int64), sqr(qword) in systemh.inc/generic.inc (previous
|
|
fixes were required to be able to add them)
|
|
* is_in_limit() moved from ncal to types unit, should always be used
|
|
instead of direct comparisons of low/high values of orddefs because
|
|
qword is a special case
|
|
|
|
}
