+ the compiler uses now fldz and fld1 if possible
+ some fixes to floating point registers
+ some math. functions (arctan, ln, sin, cos, sqrt, sqr, pi) are now inlined
* .... ???
if a tree uses more than registers32 regs then
internalerror(10) is issued
+ EXTTEMPREGDEBUG will also give internalerror(10) if
a same register is freed twice (happens in several part
of current compiler like addn for strings and sets)
+ message handler can now take an explicit self
* typinfo fixed: sometimes the type names weren't written
* the type checking for pointer comparisations and subtraction
and are now more strict (was also buggy)
* small bug fix to link.pas to support compiling on another
drive
* probable bug in popt386 fixed: call/jmp => push/jmp
transformation didn't count correctly the jmp references
+ threadvar support
* warning if ln/sqrt gets an invalid constant argument
+ lexlevel cleanup
normal_function_level main_program_level and unit_init_level defined
* tins_cache grown to A_EMMS (gave range check error in asm readers)
(test added in code !)
* -Un option was wrong
* _FAIL and _SELF only keyword inside
constructors and methods respectively
(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 !!
