|
|
|
|
Revision 1.72 1998/10/08 23:29:03 peter

|
|
isn't found
|
|
|
|
Revision 1.67 1998/09/26 17:45:39 peter
|
|
+ idtoken and only one token table
|
|
|
|
Revision 1.66 1998/09/24 23:49:16 peter
|
|
+ aktmodeswitches
|
|
|
|
Revision 1.65 1998/09/24 11:08:14 florian
|
|
* small problem in _proc_header with array of const fixed:
|
|
getsymonlyin doesn't set srsym to nil
|
|
|
|
Revision 1.64 1998/09/23 15:39:12 pierre
|
|
* browser bugfixes
|
|
was adding a reference when looking for the symbol

if -bSYM_NAME was used
|
|
|
|
Revision 1.63 1998/09/22 17:13:50 pierre
|
|
+ browsing updated and developed
|
|
records and objects fields are also stored
|
|
|
|
Revision 1.62 1998/09/22 15:37:21 peter
|
|
+ array of const start
|
|
|
|
Revision 1.61 1998/09/21 08:45:20 pierre
|
|
+ added vmt_offset in tobjectdef.write for fututre use
|
|
(first steps to have objects without vmt if no virtual !!)
|
|
+ added fpu_used field for tabstractprocdef :
|
|
sets this level to 2 if the functions return with value in FPU
|
|
(is then set to correct value at parsing of implementation)
|
|
THIS MIGHT refuse some code with FPU expression too complex
|
|
that were accepted before and even in some cases
|
|
that don't overflow in fact
|
|
( like if f : float; is a forward that finally in implementation
|
|
only uses one fpu register !!)
|
|
Nevertheless I think that it will improve security on
|
|
FPU operations !!
|
|
* most other changes only for UseBrowser code
|
|
(added symtable references for record and objects)
|
|
local switch for refs to args and local of each function
|
|
(static symtable still missing)
|
|
UseBrowser still not stable and probably broken by
|
|
the definition hash array !!
|
|
|
|
Revision 1.60 1998/09/17 09:42:42 peter
