(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 !!
- inc/dec didn't take care of CREGISTER
- register calculcation of inc/dec was wrong
- var/const parameters get now assigned 32 bit register, but
const parameters only if they are passed by reference !
* bug in psub.pas in function specifier removed
* stdcall allowed in interface and in implementation
(FPC will not yet complain if it is missing in either part
because stdcall is only a dummy !!)
(accepted are popstack cdecl and pascal)
+ added C vars with the following syntax
var C calias 'true_c_name';(can be followed by external)
reason is that you must add the Cprefix
which is target dependent
now all is already set correctly the first time
under EXTDEBUG try -gp to skip all other firstpasses
it works !!
* small bug fixes
- for smallsets with -dTESTSMALLSET
- some warnings removed (by correcting code !)
+ smartlink per module $SMARTLINK-/+ (like MMX) and moved to aktswitches
+ $LIBNAME to set the library name where the unit will be put in
* splitted cgi386 a bit (codeseg to large for bp7)
* nasm, tasm works again. nasm moved to ag386nsm.pas
* 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
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
+ change_keywords_to_tp implemented to remove
keywords which aren't supported by tp
* break and continue are now symbols of the system unit
+ widestring, longstring and ansistring type released
* corrected operator overloading
* corrected nasm output
+ started inline procedures
+ added starstarn : use ** for exponentiation (^ gave problems)
+ started UseTokenInfo cond to get accurate positions
* correct handling of hidding methods via virtual (COM)
* correct result type of constructor calls (COM), the resulttype
depends now on the type of the class reference
ADD ADC and AND are also sign extended
nasm output OK (program still crashes at end
and creates wrong assembler files !!)
procsym types sym in tdef removed !!
* overflow checking bugfix (m68k and i386) -- pretty useless in
secondadd, since everything is done using 32-bit
* loading pointer to routines hopefully fixed (m68k)
* flags problem with calls to RTL internal routines fixed (still strcmp
to fix) (m68k)
* #ELSE was still incorrect (didn't take care of the previous level)
* problem with filenames in the command line solved
* problem with mangledname solved
* linking name problem solved (was case insensitive)
* double id problem and potential crash solved
* stop after first error
* and=>test problem removed
* correct read for all float types
* 2 sigsegv fixes and a cosmetic fix for Internal Error
* push/pop is now correct optimized (=> mov (%esp),reg)
