(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 !!
* unit in interface uses and implementation uses gives error now
* only one error for unknown symbol (uses lastsymknown boolean)
the problem came from the label code !
+ first inlined procedures and function work
(warning there might be allowed cases were the result is still wrong !!)
* UseBrower updated gives a global list of all position of all used symbols
with switch -gb
+ V_Normal which is between V_Error and V_Warning and doesn't have a
prefix like error: warning: and is included in V_Default
* fixed some messages
* first time parameter scan is only for -v and -T
- removed old style messages
+ consts labels are now concated/generated in hcodegen
* moved some cpu code to cga and some none cpu depended code from cga
to tree and hcodegen and cleanup of hcodegen
* assembling .. output reduced for smartlinking ;)
UseTokenInfo greatly simplified
+ added check for changed tree after first time firstpass
(if we could remove all the cases were it happen
we could skip all firstpass if firstpasscount > 1)
Only with ExtDebug
* corrected operator overloading
* corrected nasm output
+ started inline procedures
+ added starstarn : use ** for exponentiation (^ gave problems)
+ started UseTokenInfo cond to get accurate positions
