* small update to support ibstartdef
Revision 1.12 1998/09/21 08:45:28 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 1.11 1998/09/18 08:01:42 pierre
