|
* very basic widestring support
|
|
|
|
Revision 1.70 1999/12/02 11:28:27 peter
|
|
* moved verbose to implementation uses
|
|
|
|
Revision 1.69 1999/12/01 22:32:35 pierre
|
|
* give info of original duplicated symbol more often
|
|
|
|
Revision 1.68 1999/11/30 10:40:56 peter
|
|
+ ttype, tsymlist
|
|
|
|
Revision 1.67 1999/11/24 11:41:05 pierre
|
|
* defaultsymtablestack is now restored after parser.compile
|
|
|
|
Revision 1.66 1999/11/22 00:23:09 pierre
|
|
* also complain about unused functions in program
|
|
|
|
Revision 1.65 1999/11/19 14:49:15 pierre
|
|
* avoid certain wrong notes/hints
|
|
|

Revision 1.64 1999/11/18 15:34:48 pierre
|
|
* Notes/Hints for local syms changed to
|
|
Set_varstate function
|
|
|
|
Revision 1.63 1999/11/17 17:05:06 pierre
|
|
* Notes/hints changes
|
|
|
|
Revision 1.62 1999/11/15 22:00:48 peter
|
|
* labels used but not defined give error instead of warning, the warning
|
|
is now only with declared but not defined and not used.
|
|
|
|
Revision 1.61 1999/11/15 17:52:59 pierre
|
|
+ one field added for ttoken record for operator
|
|
linking the id to the corresponding operator token that
|
|
can now now all be overloaded
|
|
* overloaded operators are resetted to nil in InitSymtable
|
|
(bug when trying to compile a uint that overloads operators twice)
|
|
|
|
Revision 1.60 1999/11/09 23:35:50 pierre
|
|
+ better reference pos for forward defs
|
|
|

Revision 1.59 1999/11/06 16:21:57 jonas
|
|
+ search optimial register to use in alignment code (compile with
|
|
-dalignreg, -dalignregdebug to see chosen register in
|
|
assembler code). Still needs support in ag386bin.
|
|
|

not yet for functions inside other functions
