(not very efficient but should work !)

|
|
|
|
Revision 1.74 1998/09/21 08:45:25 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

UseBrowser still not stable and probably broken by

|
the definition hash array !!
