Revision 1.15 1999-02-22 13:07:11 pierre
+ -b and -bl options work !
+ cs_local_browser ($L+) is disabled if cs_browser ($Y+)
is not enabled when quitting global section
* local vars and procedures are not yet stored into PPU
Revision 1.14 1999/01/20 10:20:22 peter
* don't make localvar copies for assembler procedures
Revision 1.13 1999/01/14 21:49:59 peter
* fixed forwardpointer problem with multiple forwards for the same
typesym. It now uses a linkedlist instead of a single pointer
Revision 1.12 1999/01/12 14:25:37 peter
+ BrowserLog for browser.log generation
+ BrowserCol for browser info in TCollections
* released all other UseBrowser
Revision 1.11 1998/12/30 22:15:55 peter
+ farpointer type
* absolutesym now also stores if its far
Revision 1.10 1998/12/30 13:41:15 peter
* released valuepara
Revision 1.9 1998/11/28 16:20:57 peter
+ support for dll variables
Revision 1.8 1998/11/18 15:44:19 peter
* VALUEPARA for tp7 compatible value parameters
Revision 1.7 1998/11/16 10:13:50 peter
* label defines are checked at the end of the proc
Revision 1.6 1998/11/13 10:18:12 peter
+ nil constants
Revision 1.5 1998/11/05 23:39:32 peter
+ typedconst.getsize
Revision 1.4 1998/10/20 08:07:02 pierre
* several memory corruptions due to double freemem solved
=> never use p^.loc.location:=p^.left^.loc.location;
+ finally I added now by default
that ra386dir translates global and unit symbols
+ added a first field in tsymtable and
a nextsym field in tsym
(this allows to obtain ordered type info for
records and objects in gdb !)
Revision 1.3 1998/10/08 17:17:34 pierre
* current_module old scanner tagged as invalid if unit is recompiled
+ added ppheap for better info on tracegetmem of heaptrc
(adds line column and file index)
* several memory leaks removed ith help of heaptrc !!
Revision 1.2 1998/09/24 15:11:18 peter
* fixed enum for not GDB
Revision 1.1 1998/09/23 12:03:57 peter
* overloading fix for array of const
