Revision 1.98 2003/01/05 22:41:40 peter

* when converting from and to currency divide or multiple the
result by 10000
Revision 1.89 2002/11/25 17:43:18 peter
* splitted defbase in defutil,symutil,defcmp
* merged isconvertable and is_equal into compare_defs(_ext)

Revision 1.88 2002/11/17 16:31:56 carl
* memory optimization (3-4%) : cleanup of tai fields,
cleanup of tdef and tsym fields.
* make it work for m68k
Revision 1.87 2002/10/10 16:07:57 florian
+ several widestring/pwidechar related stuff added
Revision 1.86 2002/10/06 16:10:23 florian
* when compiling <interface> as <interface> we can't assume
anything about relation
Revision 1.85 2002/10/05 12:43:25 carl
* fixes for Delphi 6 compilation
(warning : Some features do not work under Delphi)
Revision 1.84 2002/10/02 20:23:50 florian
- removed the relation check for <class> as <interface> because we don't
know the runtime type of <class>! It could be a child class of the given type
which implements additional interfaces
Revision 1.83 2002/10/02 20:17:14 florian
+ the as operator for <class> as <interface> has to check the parent classes as well
Revision 1.82 2002/09/30 07:00:47 florian
* fixes to common code to get the alpha compiler compiled applied
Revision 1.81 2002/09/16 14:11:13 peter

Revision 1.80 2002/09/07 20:40:23 carl
* cardinal -> longword
Revision 1.79 2002/09/07 15:25:03 peter
* old logs removed and tabs fixed
Revision 1.78 2002/09/07 12:16:04 carl
* second part bug report 1996 fix, testrange in cordconstnode
only called if option is set (also make parsing a tiny faster)
Revision 1.77 2002/09/05 05:56:07 jonas
- reverted my last commit, it was completely bogus :(
Revision 1.75 2002/09/02 19:24:42 peter
* array of char support for Str()
Revision 1.74 2002/09/01 08:01:16 daniel
* Removed sets from Tcallnode.det_resulttype
+ Added read/write notifications of variables. These will be usefull
for providing information for several optimizations. For example
the value of the loop variable of a for loop does matter is the
variable is read after the for loop, but if it's no longer used
or written, it doesn't matter and this can be used to optimize
the loop code generation.
Revision 1.73 2002/08/23 16:14:49 peter
* tempgen cleanup
* tt_noreuse temp type added that will be used in genentrycode
Revision 1.72 2002/08/20 18:23:33 jonas
* the as node again uses a compilerproc
+ (untested) support for interface "as" statements
Revision 1.71 2002/08/19 19:36:43 peter
* More fixes for cross unit inlining, all tnodes are now implemented
* Moved pocall_internconst to po_internconst because it is not a
calling type at all and it conflicted when inlining of these small
functions was requested
Revision 1.70 2002/08/17 09:23:36 florian
* first part of current_procinfo rewrite
Revision 1.69 2002/08/14 19:26:55 carl
+ generic int_to_real type conversion
+ generic unaryminus node
Revision 1.68 2002/08/11 16:08:55 florian
+ support of explicit type case boolean->char
Revision 1.67 2002/08/11 15:28:00 florian
+ support of explicit type case <any ordinal type>->pointer
(delphi mode only)
Revision 1.66 2002/08/09 07:33:01 florian
* a couple of interface related fixes
Revision 1.65 2002/07/29 21:23:42 florian
* more fixes for the ppc
+ wrappers for the tcnvnode.first_* stuff introduced
Revision 1.64 2002/07/23 12:34:30 daniel
* Readded old set code. To use it define 'oldset'. Activated by default
for ppc.
Revision 1.63 2002/07/23 09:51:22 daniel
* Tried to make Tprocsym.defs protected. I didn't succeed but the cleanups
are worth comitting.
Revision 1.62 2002/07/22 11:48:04 daniel

Revision 1.61 2002/07/20 17:16:02 florian
+ source code page support
Revision 1.60 2002/07/20 11:57:54 florian
* types.pas renamed to defbase.pas because D6 contains a types
unit so this would conflicts if D6 programms are compiled
+ Willamette/SSE2 instructions to assembler added
Revision 1.59 2002/07/01 16:23:53 peter
* cg64 patch
* basics for currency
* asnode updates for class and interface (not finished)
Revision 1.58 2002/05/18 13:34:09 peter
