Revision 1.38 2001-10-01 13:38:44 jonas
|
|
* allow self parameter for normal procedures again (because Kylix allows
|
|
it too) ("merged")
|
|
|
|
Revision 1.37 2001/09/10 10:26:26 jonas
|
|
* fixed web bug 1593
|
|
* writing of procvar headers is more complete (mention var/const/out for
|
|
paras, add "of object" if applicable)
|
|
+ error if declaring explicit self para as var/const
|
|
* fixed mangled name of procedures which contain an explicit self para
|
|
* parsing para's should be slightly faster because mangled name of
|
|
procedure is only updated once instead of after parsing each para
|
|
(all merged from fixes)
|
|
|
|
Revision 1.36 2001/08/26 13:36:45 florian
|
|
* some cg reorganisation
|
|
* some PPC updates
|
|
|
|
Revision 1.35 2001/08/23 14:28:36 jonas
|
|
+ tempcreate/ref/delete nodes (allows the use of temps in the
|
|
resulttype and first pass)
|
|
* made handling of read(ln)/write(ln) processor independent
|
|
* moved processor independent handling for str and reset/rewrite-typed
|
|
from firstpass to resulttype pass
|
|
* changed names of helpers in text.inc to be generic for use as
|
|
compilerprocs + added "iocheck" directive for most of them
|
|
* reading of ordinals is done by procedures instead of functions
|
|
because otherwise FPC_IOCHECK overwrote the result before it could
|
|
be stored elsewhere (range checking still works)
|
|
* compilerprocs can now be used in the system unit before they are
|
|
implemented
|
|
* added note to errore.msg that booleans can't be read using read/readln
|
|
|
|
Revision 1.34 2001/08/22 21:16:21 florian
|
|
* some interfaces related problems regarding
|
|
mapping of interface implementions fixed
|
|
|
|
Revision 1.33 2001/08/19 21:11:20 florian
|
|
* some bugs fix:
|
|
- overload; with external procedures fixed
|
|
- better selection of routine to do an overloaded
|
|
type case
|
|
- ... some more
|
|
|
|
Revision 1.32 2001/08/19 11:22:23 peter
|
|
* palmos support from v10 merged
|
|
|
|
Revision 1.31 2001/08/05 13:18:50 peter
|
|
* turn pocall_inline off when inline is not supported
|
|
|
|
Revision 1.30 2001/08/01 15:07:29 jonas
|
|
+ "compilerproc" directive support, which turns both the public and mangled
|
|
name to lowercase(declaration_name). This prevents a normal user from
|
|
accessing the routine, but they can still be easily looked up within
|
|
the compiler. This is used for helper procedures and should facilitate
|
|
the writing of more processor independent code in the code generator
|
|
itself (mostly written by Peter)
|
|
+ new "createintern" constructor for tcal nodes to create a call to
|
|
helper exported using the "compilerproc" directive
|
|
+ support for high(dynamic_array) using the the above new things
|
|
+ definition of 'HASCOMPILERPROC' symbol (to be able to check in the
|
|
compiler and rtl whether the "compilerproc" directive is supported)
|
|
|
|
Revision 1.29 2001/07/09 21:11:14 peter
|
|
* fixed overload checking for delphi. Empty parameters are only
|
|
allowed in implementation and not when the forward declaration
|
|
contains overload directive
|
|
|
|
Revision 1.28 2001/07/01 20:16:16 peter
|
|
* alignmentinfo record added
|
|
* -Oa argument supports more alignment settings that can be specified
|
|
per type: PROC,LOOP,VARMIN,VARMAX,CONSTMIN,CONSTMAX,RECORDMIN
|
|
RECORDMAX,LOCALMIN,LOCALMAX. It is possible to set the mimimum
|
|
required alignment and the maximum usefull alignment. The final
|
|
alignment will be choosen per variable size dependent on these
|
|
settings
|
|
|
|
Revision 1.27 2001/06/04 18:12:26 peter
|
|
* fixed crash with procvar directive parsing. Be carefull as the procvar
|
|
directive parsing uses aktprocsym.definition that is a tprocdef, but
|
|
for procvar the type is tprocvardef. So some fields are not available
|
|
|
|
Revision 1.26 2001/06/04 11:53:13 peter

Revision 1.25 2001/06/03 21:57:36 peter
